From ab1ae150f73199fbd64449eb7c43fd1f45a29c5d Mon Sep 17 00:00:00 2001 From: cloudQuant Date: Thu, 3 Sep 2026 06:34:08 +0800 Subject: [PATCH 01/83] docs(strategies): add bilingual strategy series covering all 1,152 backtests - New docs/source/strategies-series/ with 43 Chinese articles and 30 English category digests (+ 2 bilingual overview pages) - One article per strategy family across all 30 categories in tests/functional/strategies; deep dives verified against test source and asserted baselines - Mount series into site navigation (index.rst / index_zh.rst) via glob toctree; exclude opposite-language dir per build in conf.py - All source links point to the development branch (default) --- docs/source/conf.py | 6 + docs/source/index.rst | 7 + docs/source/index_zh.rst | 7 +

Compendium** is a serialized deep-dive into the **1,152 strategy backtests** living in [tests/functional/strategies](https://github.com/cloudQuant/backtrader/tree/main/tests/functional/strategies) of this repository. They span **30 categories** — from the classic Turtle Trader and Dual Thrust breakouts, through HMM regime switching and Kalman-filtered pairs trading, to grid/martingale systems and options expiration-week effects. Every one of them is a **complete, runnable backtest with precise assertions** — not pseudocode, not a toy example. + +Why this matters: + +1. **Real data** — XAUUSD (gold) M15/D1 bars, rebar & glass futures minute data, ORCL daily prices; +2. **Asserted metrics** — final portfolio value, Sharpe ratio, and max drawdown are compared against baselines (e.g., the Donchian test asserts `final_value` within 0.01); +3. **Dual-mode parity** — each strategy runs in both vectorized (`runonce=True`) and event-driven (`runonce=False`) engine modes and must produce identical results, guarding engine correctness. + +All of this rides on the [cloudQuant/backtrader](https://github.com/cloudQuant/backtrader) high-performance engine: 46% faster than the original in pure Python, 128x median speedup with the C++/pybind11 backend, and 3,200+ tests protecting correctness. + +## Series Index + +> All 30 digests published (completed 2026-09-02).

It is the first "technical analysis" most traders ever meet: fast line crosses above slow line, buy; crosses below, sell. And because it is so simple, it is also the most underestimated family in the shop — within this repository's `trend_following` category (340 strategies), crossovers and their close relatives alone occupy roughly 69 seats. + +Here is a counterintuitive fact to set the tone: on gold's 2008-2025 bull run, a bare 50/200 golden-cross system traded only **13 times in 18 years**, won fewer than a third of those trades, and still turned 1,000,000 into 3,571,828. Win rate and profit are different variables — that is lesson one of trend following. + +This digest tours the category through three of its highlights: the patient Golden Cross, the full Original Turtle Rules (position engineering, not just signals), and a Hidden Markov Model that turns "what regime are we in" into a computable quantity.

The signal is sparse, lagging, and very quiet. + +The implementation ([test_0175](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/trend_following/test_0175_golden_cross.py)) precomputes signals in pandas and keeps the strategy side dumb: + +```python +out['ma_fast'] = out['close'].rolling(window=fast_period).mean() # fast = 50 +out['ma_slow'] = out['close'].rolling(window=slow_period).mean() # slow = 200 + +out['golden_cross'] = ((out['ma_fast'].shift(1) <= out['ma_slow'].shift(1)) & + (out['ma_fast'] > out['ma_slow'])).astype(float) +out['death_cross'] = ((out['ma_fast'].shift(1) >= out['ma_slow'].shift(1)) & + (out['ma_fast'] < out['ma_slow'])).astype(float) + +def next(self): + golden_cross = float(self.data.golden_cross[0]) > 0.5 + death_cross = float(self.data.death_cross[0]) > 0.5 + if not self.position: + if golden_cross: + self.pending_order = self.buy(size=self._get_position_size( + target_notional_pct=float(self.p.lot_size))) + return + if death_cross: + self.pending_order = self.close() +``` + +Note the `shift(1)`: the cross must compare the *previous* bar's averages, so a signal cannot retro-fit itself on the current bar. + +**The pinned baseline.** XAUUSD daily 2008-2025, 1,000,000 initial, 0.02% commission: 13 trades, 4 wins and 8 losses (one open), a 30.77% win rate, final value **3,571,828.03** (+257.18%), profit factor 2.04, max drawdown 37.54%. The test pins every number with tolerances like `abs(final_value - 3571828.03) < 3.6`. A 31% win rate making 2.5x on the back of a 2:1 payoff profile is trend following in one sentence: cut losses, let winners run. + +The neighboring control group sharpens the point. The price-crossing variant ([test_0001](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/trend_following/test_0001_sma_trend_following.py)) trades 65 times (16.92% win rate) for a similar 3,686,124.79 — five times the turnover for the same money. And the death-cross-reverse strategy ([test_0174](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/trend_following/test_0174_death_cross_reverse.py)) bets on the *opposite* side of the same signal: 12 trades, 75% win rate, +28.41%. Same indicator, three coherent uses. + +## Deep Dive 2: Original Turtle Rules — the Signal Is 10% of the System + +The minimal Turtle rule fits in one line (see [No. 15](15-breakout.md) for the Donchian minimal version). The full rulebook Richard Dennis handed his students is mostly *position engineering*: ATR-sized units, pyramiding every 1×ATR of favorable movement, a 4-unit cap. [test_0074](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/trend_following/test_0074_0776_original_turtle_rules_trader.py) ports all of it — `n_st=20` (system-one channel), `n_lt=55` (backup channel after a failed breakout), `n_exit=10`, `atr_period=20`, `max_risk=0.01`. + +The soul of the system is the unit size — **each unit risks only 1% of equity, converted to lots through ATR**: + +```python +def _unit_size(self): + atr = float(self.atr[-1]) if len(self) > 1 else float(self.atr[0]) + if atr <= 0: + return self.p.volume_min + equity = self.broker.getvalue() + risk_budget = equity * self.p.max_risk # 1% of equity per unit + unit = risk_budget / max(atr * self.p.stop_loss * self.p.multiplier, 1e-9) + return self._round_volume(unit) +``` + +Entries fire on a 20-day channel break (a 55-day backup re-confirmation follows a failed breakout); stops sit 1×ATR from entry; and each new unit of profit adds another unit: + +```python +st_upper = self._channel_max(self.p.n_st) +st_breakout = self._breakout(close, st_upper, st_lower) +if st_breakout == 0: + return +unit = self._unit_size() +self._set_risk_prices(st_breakout, close) # stop = entry ∓ 1×ATR +self.entry_order = self.buy(size=unit) if st_breakout > 0 else self.sell(size=unit) + +# inside the position manager: add a unit every adding_interval × ATR of profit +if (close - self.last_entry_price) * current_direction > self.p.adding_interval * atr: + self.entry_order = self.buy(size=unit) if current_direction > 0 else self.sell(size=unit) +``` + +Baseline on three months of XAUUSD M15: 6,109 bars, 345 trades, 173 wins vs 172 losses (50.14% win rate), final value **1,190,431.17** (+19.04%), profit factor 1.23, max drawdown just 8.08%. A coin-flip win rate that still compounds — the profit lives entirely in the position structure: add into trends, stop at the start of them. + +## Deep Dive 3: Gold HMM — Making "Regime" Computable + +"Is this a bull market?" Humans answer with feel; a hidden Markov model answers with posterior probabilities. [test_0002](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/trend_following/test_0002_gold_hmm_trend_following.py) is a hand-written 431-line test that rolls a 3-state `GaussianHMM(covariance_type="full")` over gold daily bars — retrained every 21 days on a 252-day window, using just two features: log returns and 20-day annualized volatility. Raw states are then *labeled* BULL/BEAR/NEUTRAL by their mean return on the training set. + +A state alone is not enough; the model must also be confident: + +```python +vol_factor = min(target_volatility / max(float(current_row["volatility_20"].iloc[0]), 1e-6), + max_target_percent / max(base_target_percent, 1e-6)) +dynamic_target = min(max_target_percent, base_target_percent * current_confidence * vol_factor) +if current_confidence < state_persistence_min or persistence < state_persistence_min or consistent < 0.5: + dynamic_target = 0.0 +``` + +Target exposure is `min(0.10, 0.03 × confidence × volatility factor)`, and any of three trust checks — state posterior, transition-matrix stickiness, three consecutive same-state days — falling below 0.7 zeroes the position. Once unrealized profit reaches 8%, the stop ratchets from −3% to break-even. Result over 2024-2025: 245 daily bars, just 6 trades (3 wins, 3 losses), final value 1,001,059.99 — roughly flat after commissions. Two engineering habits worth stealing: `pytest.importorskip("hmmlearn")` degrades gracefully when the ML dependency is absent, and HMM features are precomputed in pandas, keeping the backtest engine itself pure. + +## The Rest of the Bench + +- **MACD, three fates** (`test_0116`/`test_0163`/`test_30`): the MT5 official template with a zero-axis filter loses gently (-0.19%, PF 0.60); the naked stop-and-reverse crossover bleeds slower (-0.72% over 474 trades); and the MACD+KDJ combo with all-in sizing turns 100,000 into 5,870.49 — a 98.63% drawdown preserved forever as a lesson: sizing *is* the strategy. +- **ADX gates and trailing stops** (`test_0064`, `test_0140`): the ADX+MA gate wins 45.5% and loses money; the ATR chandelier wins only 35.5% yet profits (PF 1.117, Sharpe 4.40).

Thirty years later Larry Connors turned that doctrine upside down: cut the period to 2, cut the threshold to 5, and **only ever buy oversold in an uptrend**. + +That is a complete reinterpretation of the word "oversold." In Wilder's frame, an RSI of 20 means falling momentum — stay away. In Connors' frame, an extremely oversold reading inside a long-term uptrend is precisely the golden dip-buy, because the "mean" you are reverting to is itself rising. This digest walks the 331 backtests in `tests/functional/strategies/mean_reversion/` through three of them: the classic RSI2, the smoothed-oscillator school of KDJ and DiNapoli, and Connors' one-line classic Double 7s.

And `sma_period=100` is the seatbelt: in 2008, 2013, or 2021-style crashes the RSI(2) hugs the floor for weeks, but with price below the mean, not one signal fires. + +The asserted baseline: 4,538 daily bars, 311 trades, **67.85% win rate**, final value **1,703,436.24** (+70.34%), max drawdown 17.37%, SQN 2.06. Not a fortune machine — but a four-parameter rule system holding two-thirds winners over 17 years is exactly why this is the textbook of short-term reversion. Its composite sibling ([test_0020](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/mean_reversion/test_0020_connorsrsi_mean_reversion.py)) averages price momentum, *streak* RSI (RSI of the win/loss streak itself), and percent rank into one score, then enters via limit orders 0.3% below yesterday's close: just 38 fills in 17 years (14 limit orders expired unfilled), 78.95% win rate, profit factor 3.38, max drawdown 6.42%. Pickier entry, cheaper fills, shallower drawdowns — "less is more" with receipts. + +## Deep Dive 2: KDJ and DiNapoli — Taming a Twitchy Oscillator + +Raw oscillators jitter; the interesting engineering question is how to make them tradeable. The KDJ system ([test_0239](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/mean_reversion/test_0239_0515_kdj_trading_system.py)) — the stochastic's Chinese-market evolution — computes KDJ(30, 3, 6) on an H1 resampled feed and executes on M15: + +```python +self.kdj = bt.indicators.KDJIndicator(self.data_h1, m1=3, m2=6, kdj_period=30) + +# long: the KDC midline flips positive (cross), or K is positive and still rising +if (val_kdc_prev < 0.0 and val_kdc_current > 0.0) or \ + (val_kdc_current > 0.0 and (val_k_prev - val_k_current) < 0.0): + self.stop_price = self._round(price - sl_dist) # 25-point stop + self.take_profit_price = self._round(price + tp_dist) # 45-point target + self.order = self.buy(data=self.data, size=float(self.p.lots)) +``` + +Three months of M15: 1,149 trades, 50.22% win rate, profit factor 1.16, final value 1,006,404 — thin-edge, high-volume reversion earning discipline and spread control. + +DiNapoli goes the opposite way: slow the oscillator down. [test_0275](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/mean_reversion/test_0275_1013_dinapoli_stochastic.py) takes an 8-period raw %K, then applies recursive exponential smoothing twice: + +```python +res = 100.0 * (frame['close'] - lowest) / raw_range # 8-period raw %K + +for value in res.tolist(): + prev_sto = prev_sto + (float(value) - prev_sto) / max(1, int(slow_k)) # 3-period main + prev_sig = prev_sig + (prev_sto - prev_sig) / max(1, int(slow_d)) # 3-period signal + +buy_signal = (sto.shift(1) > sig.shift(1)) & (sto <= sig) # main crosses BELOW signal = buy +``` + +Read that last line twice: the main line crossing *below* the signal line is the buy — pure contrarian, betting price follows the oscillator's first step down from a high. Signals evaluate on a 6-hour frame; the result is 24 trades in three months (14 wins, 9 losses, 58.33%), final value 1,000,797.20. Two smoothings turn an aggressive reversal rule into a low-frequency, holdable system. + +## Deep Dive 3: Double 7s — A Classic Rule, Frozen in Assertions + +Blog folklore mutates: parameters drift, conditions get added, samples get cherry-picked. The cure is freezing the rule in code and pinning the result.

The neighboring `test_0010_double_n_gold.py` re-implements the same idea with N instead of 7 and asserts identical numbers — two independent implementations proving the rule didn't warp in translation. Related frozen classics: consecutive-down-days (203 trades, 56.65%, final 1,167,207.74 — note the -0.1% daily threshold and the 5-day cap that refuses falling knives) and the efficiency-ratio gate (548 trades, final 2,700,065.50) that only buys oversold when Kaufman's ER says the market is choppy. + +## The Rest of the Bench + +- **BB Squeeze** (`test_0224`): the category's traitor — after a Bollinger-inside-Keltner compression, it trades *momentum* on the release: 309 trades, 40.78% win rate, PF 1.27. +- **The 3σ touch-reversion** (`test_0140_0616_bollinger.py`): an 80-period, 3σ band requiring the *whole bar* outside the band — 4 trades in 6,050 bars, all winners, final value 999,218.55. Signal quality versus signal quantity, quantified. +- **A four-way confirmator experiment** (`test_0225`–`test_0228`): identical three-crows/soldiers detector, only the confirming oscillator swapped (RSI/MFI/CCI/Stoch) — the cleanest design for studying "which confirmator." +- **Statistical tail** (`test_0009`, `test_63`): gold z-score reversion wins 63.46% to a final 1,289,841.82; the Visa/Mastercard pairs trade finishes flat with a 1.157% max drawdown — and doubles as a runonce/runnext parity exemplar. + +## Run It Yourself + +```bash +# The whole category (331 strategies, runonce/runnext parity asserted automatically) +pytest tests/functional/strategies/mean_reversion/ -v + +# Just the classic Connors RSI2 +pytest tests/functional/strategies/mean_reversion/test_0004_rsi2_mean_reversion.py -v +``` + +## Why Study Mean Reversion Here + +The RSI family is among the most parameter-sensitive in existence — period 2 or 3, threshold 5 or 10, mean 100 or 200; every knob reshapes the trade distribution, and without mass reproduction you cannot tell edge from luck.

The canonical trend-following profile: many small losses exchanged for a few large wins. Note two quiet guardrails: position sizing divides by the contract multiplier (100), so futures margin is not silently 100x-leveraged; and a `pending_order` gate stops `next()` from re-firing while an order is alive — the kind of detail that makes cent-level assertion parity possible. + +## Deep Dive 2: Relative Momentum as a Ranking + +A single asset can only answer "in or out."

The headline number, though, is the max drawdown: **12.08%**, versus 33.71% for the single-asset switch. No line of "market timing" code exists anywhere — the two momentum conditions migrate the portfolio to risk assets in bulls and to cash when even the strongest asset is falling. That is why dual momentum earned its place in allocation circles. + +## Deep Dive 3: The 52-Week High — Anchored, Not Broken + +George and Hwang (2004) found that *proximity to the 52-week high* predicts returns better than conventional momentum — the behavioral read is anchoring: investors fixate on the high, so price near it is "expensive" and under-reacts.

The most famous reversal pattern in the world, implemented to textbook standard, is noise at this frequency in a trending market like gold. + +Now add the second vote. [test_0028](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/price_patterns/test_0028_1339_engulfing_rsi.py) keeps the engulfing but requires a *meaningful* bar and an oscillator opinion: + +```python +def _bullish_engulfing(self): + o2, c2 = float(self.data.open[-2]), float(self.data.close[-2]) + o1, c1 = float(self.data.open[-1]), float(self.data.close[-1]) + avg = self._avg_body() # rolling mean body (SMA 5) + mid2 = (o2 + c2) / 2.0 + close_avg = float(self.sma[-2]) + return ( + o2 > c2 and # previous bar bearish + (c1 - o1) > avg and # body beats the rolling average + c1 > o2 and # closes past the prior open + mid2 < close_avg and # pattern sits below the SMA + o1 < c2 + ) + +# entry: pattern AND regime — previous RSI(11) below 40 for longs, above 60 for shorts +if bull_eng and rsi_1 < 40: + self.buy(...) +``` + +Same data, same engine: 27 trades, 10 wins, **37.04% win rate**, final value 996,678.80.

Push further with *location* (hammer hanging below its SMA) plus RSI(14) in `test_0023_1323_hammer_rsi.py` and the win rate reaches 52.38%. The A/B ladder — pattern, pattern+momentum, pattern+location+momentum — is the real teaching artifact here. + +## Deep Dive 2: NR7 — Crabel's Volatility-Contraction Law + +Toby Crabel's observation: the day with the narrowest range of the last seven tends to precede range expansion. [test_0037](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/price_patterns/test_0037_nr7_pattern_breakout.py) implements it over 18 years of gold daily bars — detection is a one-liner, the discipline lives in the exits: + +```python +out['daily_range'] = out['high'] - out['low'] +out['min_range_prev6'] = out['daily_range'].shift(1).rolling(window=lookback - 1).min() +out['nr7'] = (out['daily_range'] < out['min_range_prev6']).astype(float) +out['breakout_up'] = ((out['nr7'].shift(1) > 0.5) & + (out['close'] > out['nr7_high'])).astype(float) + +self.stop_loss = self.entry_price - self.p.stop_loss_atr * atr # 2.5 × ATR +self.take_profit = self.entry_price + self.p.take_profit_atr * atr # 4.0 × ATR +if bars_held >= self.p.time_exit: # 5 bars, then out + self.pending_order = self.close() +``` + +The 5-bar time stop is the strategy's soul: NR7 bets on *immediate* expansion, so a squeeze that hasn't delivered within a week is simply wrong. Baseline: 132 trades, 48.48% win rate, final value **1,310,862.61** (+31.09%), Sharpe 0.46 — bought at the price of a 49.46% max drawdown. A 1.6:1 payoff ratio near coin-flip odds is positive expectation; the drawdown column is the cardiologist's opinion. Sibling variants (`test_0038`, `test_0039`) add trend-mean filters and volatility-gated exits for contrast. + +## Deep Dive 3: Darvas Boxes — the Dancer's Legacy, Engineered + +In 1960, dancer Nicolas Darvas turned roughly $25,000 into $2 million trading boxes from telegraphed quotes while touring the world. [test_0044](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/price_patterns/test_0044_0853_darvasboxes_system.py) ports the MT5 version as a dual-timeframe system — M15 executes, H4 builds boxes — with the indicator publishing a color state and the strategy trading only *transitions*: + +```python +if len(self.signal_data) == self._last_signal_len: + return # dedupe: one look per H4 bar +self._last_signal_len = len(self.signal_data) +c0 = float(self.ind.color[-sb]) if sb else float(self.ind.color[0]) +c1 = float(self.ind.color[-(sb + 1)]) +buy_open = c1 > 2.0 and c0 < 3.0 and self.p.buy_pos_open # transition into green +sell_open = c1 < 2.0 and c0 > 1.0 and self.p.sell_pos_open # transition into red +``` + +Exits are a fixed bracket — 1,000-point stop, 2,000-point target. On the three-month window the system took 11 trades, **every one of them a short** (buy_count=0), 3 wins against 8 losses, final value 999,221.40. Structure strategies can be picky eaters about regime — that bias is invisible until you backtest. The `_last_signal_len` dedupe is the port's quiet gem: without it, one H4 signal fires four times inside its M15 children. + +## The Rest of the Bench + +- **Heikin Ashi** (`test_0015`): six lines of recursion smooth candles into color — as a *trigger* it wins 34.14% and loses gently; the lesson is to use color runs as a filter, not a gun. +- **Three Inside + bracket** (`test_0001`): MT5's bracket-order habits (`buy_bracket`, 500/500 points) faithfully translated — entries by pattern, exits by order types, separable concerns. +- **Doji breakout** (`test_0005`): refuses to read the doji as reversal; treats it as a springboard and trades the break of its extremes. +- **Close-price fractals** (`test_0041`, `test_0043`): Williams fractals computed on closes (fewer shadow traps), with a minimum-distance gate that refuses whipsaw markets. +- **Adaptive Renko** (`test_0036`): brick size breathes with ATR — noise below one brick simply ceases to exist. + +## Run It Yourself + +```bash +# The whole category (44 strategies) +pytest tests/functional/strategies/price_patterns/ -v + +# Just the RSI-confirmed engulfing +pytest tests/functional/strategies/price_patterns/test_0028_1339_engulfing_rsi.py -v +``` + +## Why Study Price Patterns Here + +Pattern strategies live and die by details — an extra boolean in the engulfing definition, an RSI threshold moved from 40 to 35, a 1:1 versus 1:2 bracket.

The setup is four AND-ed conditions: + +```python +out['prior_day_new_low'] = out['new_50d_low'].shift(1).fillna(0.0) # yesterday: 50-day low +out['gap_up_abs'] = out['open'] - out['prev_close'] +pct_gap_trigger = out['gap_up_abs'] > (out['prev_close'] * gap_threshold_pct) # 0.3% +atr_gap_trigger = out['gap_up_abs'] > (out['atr'] * gap_atr_multiple) # 0.5 × ATR(14) +out['significant_gap_up'] = (pct_gap_trigger | atr_gap_trigger).astype(float) +out['gap_unfilled'] = (out['close'] > out['prev_close']).astype(float) # gap never filled +out['close_above_open'] = (out['close'] > out['open']).astype(float) # bullish confirmation + +out['setup_signal'] = ((out['prior_day_new_low'] > 0.5) & (out['significant_gap_up'] > 0.5) + & (out['gap_unfilled'] > 0.5) & (out['close_above_open'] > 0.5)).astype(float) +``` + +Two details travel well: "significant" gap is a dual trigger — percent *or* ATR-scaled — so volatile months automatically raise the bar; and the exit is purely temporal (2 days), no stop, no target — removing every human temptation to "hold until it comes back." The baseline is honesty itself: in 4,588 daily bars, the setup fired **6 times** — 3 wins, 3 losses, final value 1,030,141.98 (+3.01%), profit factor 1.56, max drawdown 3.27%.

Over 18 years of GLD: average exposure just 10.1%, final value **1,250,223.05** (+25.0%), max drawdown 5.16%, Sharpe 0.53.

The diagnosis is more interesting than the number: gold has spent these 18 years being a famously *trending* market, and the mean-reversion leg kept getting run over by one-way moves.

It assumes three hidden states and infers them from three observables — log return, 20-day annualized volatility, 60-day momentum — refitting a `GaussianHMM` on the trailing 252 bars, retraining every 63 days: + +```python +model = GaussianHMM(n_components=n_states, covariance_type='full', + n_iter=300, random_state=42) # n_states = 3 +model.fit(train_std) +labels = _label_states(model, train_std) # relabel states BULL/BEAR/NEUTRAL by mean return + +current_state = int(state_seq[-1]) +current_confidence = float(proba[-1, current_state]) +consistent = len(recent_states) >= smoothing_window and \ + all(s == current_state for s in recent_states[-smoothing_window:]) # 5 straight days + +signed_target = 0.0 +if current_confidence >= confidence_threshold and consistent: # confidence ≥ 0.55 + if current_label == 'BULL': + signed_target = min(1.0, 1.0 * current_confidence) # long, scaled by confidence + elif current_label == 'BEAR': + signed_target = max(-0.5, -0.5 * current_confidence) # small short +``` + +Both defenses matter. HMM state *numbers* are meaningless — state 0 can be a bull this month and a bear after the next retrain — so states are relabeled by their mean standardized return every time. And regime signals are noisy, so exposure requires confidence above 0.55 **and** five consecutive days of agreement: better late than wrong. Over the 2024-2025 window (205 bars, 4 retrains): 27 signal changes, but the gates admitted only **2 trades — both winners** — final value 1,014,553.76 (+1.46%), SQN 4.76, max drawdown 4.22%. One more habit worth copying: the module opens with `pytest.importorskip("hmmlearn")`, so a missing optional ML dependency skips gracefully instead of painting CI red. + +## Deep Dive 2: The Asymmetric Bollinger — a 3σ Door In, a 1σ Door Out + +Anyone can write a Bollinger breakout. The soul of [test_0021](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/volatility_systems/test_0021_bollinger_band_breakout.py) is that entry and exit live at *different* sigmas: + +```python +out['bb_middle'] = out['close'].rolling(bb_period).mean() # bb_period = 100 +out['bb_std'] = out['close'].rolling(bb_period).std() +out['bb_upper_entry'] = out['bb_middle'] + entry_dev * out['bb_std'] # +3.0σ to enter +out['bb_lower_exit'] = out['bb_middle'] - exit_dev * out['bb_std'] # -1.0σ to exit +out['entry_signal'] = (out['close'] > out['bb_upper_entry']).astype(float) +out['exit_signal'] = (out['close'] < out['bb_lower_exit']).astype(float) +``` + +Requiring a close above three standard deviations filters 18 years of daily bars down to **7 entries**; exiting at just one sigma below the mean gives trends a wide runway. The result is a textbook low-frequency trend profile: 7 trades, 3 wins and 3 losses closed (42.9% win rate), profit factor **2.97**, final value **3,076,810.25** (+207.7%), max drawdown 23.1%. Low win rate × high payoff — the exact mirror image of the HMM's two-trade precision, and both are trend strategies. Same goal, two architectures, assertions holding each to its word. + +## Deep Dive 3: Fisher Cyber Cycle — Ehlers' Filter Philosophy + +Most indicators are statistics; Ehlers' indicators are filters. [test_0019](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/volatility_systems/test_0019_fisher_cyber_cycle.py) smooths the median price, extracts the cycle with a second-order super-smoother, normalizes it, then applies the Fisher transform — which stretches any distribution toward Gaussian and makes turning points knife-sharp: + +```python +k0 = (1.0 - 0.5 * alpha) ** 2 # alpha = 0.07 +k2 = 2.0 * (1.0 - alpha) +k3 = (1.0 - alpha) ** 2 +smooth[bar] = (price[bar] + 2.0*price[bar-1] + 2.0*price[bar-2] + price[bar-3]) / 6.0 +cycle[bar] = k0*(smooth[bar] - 2.0*smooth[bar-1] + smooth[bar-2]) \ + + k2*cycle[bar-1] - k3*cycle[bar-2] # Cyber Cycle +value1[bar] = (cycle[bar] - ll) / (hh - ll) # normalize in a length-8 window +weighted = (4.0*vals[-1] + 3.0*vals[-2] + 2.0*vals[-3] + vals[-4]) / 10.0 +scaled = 1.98 * (weighted - 0.5) +scaled = min(max(scaled, -0.999999), 0.999999) # clamp: Fisher diverges at ±1 +fish[bar] = 0.5 * math.log((1.0 + scaled) / (1.0 - scaled)) # Fisher transform +trigger[bar] = fish[bar - 1] # trigger lags one bar +``` + +Fish crossing its trigger line trades the turn; signals compute on an H8 (480-minute) resampled stream, orders execute on M15, with a 1,000/2,000-point stop/target bracket. Three months: 18 trades, 7 wins, 11 losses, final value 996,022.30 (-0.40%) — a losing baseline pinned by assertion. It proves not "Ehlers doesn't work" but "these parameters had no positive expectation on this window," and it leaves you a controlled starting point. Note the clamp line, a small monument of numerical engineering: the Fisher transform diverges at ±1, and one `min(max(...))` prevents a NaN cascade. + +## The Rest of the Bench + +- **VIX-SPX divergence** (`test_0011`): no VIX data? Use realized volatility — short when price prints a new high while volatility rises and the price-vol correlation breaks. +- **Adaptive VIX MA** (`test_0012`): the volatility percentile over 500 days sets the EMA's alpha (constant 4.6) — the more extreme the regime, the tighter the average hugs price. +- **Gold volatility position** (`test_0005`): tercile sizing — full position below the 20th percentile, half above the 80th, 75% in between. "Be greedy when others are fearful," as three if-statements. +- **Volatility long memory** (`test_0010`): runs Hurst on the *volatility series* — trending vol follows a moving average, anti-persistent vol trades reversal. +- **Correlation regime** (`test_0015`): the stock-bond correlation is a free risk barometer — negative means risk-on (equities), positive means risk-off (bonds), ambiguous means stay balanced. + +## Run It Yourself + +```bash +# The whole category (32 strategies) +pytest tests/functional/strategies/volatility_systems/ -v + +# Just HMM regime detection (requires hmmlearn) +pytest tests/functional/strategies/volatility_systems/test_0007_0125_hmm_regime_detection.py -v +``` + +## Why Study Volatility and Regimes Here + +Regime-switching strategies are the ceiling of backtest complexity: HMMs refit on a rolling window, Ehlers systems align dual feeds across timeframes — one run is slow enough, let alone a parameter sweep.

Three indicator families each govern one aspect: CCI(30) for momentum extremes, MACD(12, 26, 9) for momentum direction, and the EMA "camel" channel for price location. Long entry requires all four gates: + +```python +self.camel_high = bt.indicators.ExponentialMovingAverage( + self.data.high, period=self.p.ma_period_ma_high) # EMA(40) of highs +self.camel_low = bt.indicators.ExponentialMovingAverage( + self.data.low, period=self.p.ma_period_ma_low) # EMA(5) of lows +self.macd = bt.indicators.MACD(self.data.close, + period_me1=12, period_me2=26, period_signal=9) +self.cci = bt.indicators.CCI(self.data, period=self.p.ma_period_cci) # 30 + +if cci_prev > 100 and macd_main_prev > 0 \ + and macd_main_prev > macd_signal_prev \ + and close_prev > camel_high_prev: # all four green: go long + self.order = self.buy(size=self.p.lot) + +if cci_prev < -100 and macd_main_prev < 0 \ + and macd_main_prev < macd_signal_prev \ + and close_prev < camel_low_prev: # short is the exact mirror + self.order = self.sell(size=self.p.lot) +``` + +Exits also demand "consensus breakdown": while long, MACD main falling back under its signal, or CCI retreating inside 100, or a 40-pip take-profit touch — any one closes the position. Two engineering details reward close reading: every comparison uses `[-1]` (the **previous** bar's values), eliminating same-bar self-reference look-ahead; and the camel bands are deliberately asymmetric (40 vs 5), so the upper band is slow and the lower fast — longs get more room than shorts. Over three months and 6,071 M15 bars the system traded 687 times, 352 wins against 335 losses, ending at 1,038,763.00 on a 1,000,000 account (+3.88%). High-frequency micro-profit trading: the edge is ground out by win rate, one small trade at a time. + +## Deep Dive 2: MQL5 Wizard MACD + Parabolic SAR — a Scoring Lesson + +The Wizard's standard play is module voting: each module outputs ±100 times its weight, and the total crossing a line opens a trade. This port ([test_0020](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/multi_indicator_system/test_0020_mql5_wizard_macd_parabolic_sar.py)) assigns MACD the momentum seat and PSAR the trend seat: + +```python +def _macd_score(self): + if self.macd.macd[0] > self.macd.signal[0]: + return 100.0 * float(self.p.signal_macd_weight) # weight 0.9 + if self.macd.macd[0] < self.macd.signal[0]: + return -100.0 * float(self.p.signal_macd_weight) + return 0.0 + +def _sar_score(self): + if self.data.close[0] > self.sar[0]: + return 100.0 * float(self.p.signal_sar_weight) # weight 0.1 + if self.data.close[0] < self.sar[0]: + return -100.0 * float(self.p.signal_sar_weight) + return 0.0 + +def _signal_value(self): + return self._macd_score() + self._sar_score() # range [-100, +100] +``` + +With `signal_threshold_open=20`, a total of +20 or more goes long and −20 or less goes short; exits are any of fixed 50/115-point stop/target, or the score swinging to the full opposite 100 (`signal_threshold_close`) — both indicators in complete revolt. Now look harder at this "democracy": MACD's vote is worth 90 points, PSAR's only 10, and the threshold is 20 — **MACD alone can open the door; PSAR is a ceremonial voter.** Scoring looks like it smooths disagreement, but the weights decide who actually dictates. The backtest delivers a sharp verdict: 3,077 trades, 48.6% win rate, profit factor 0.915, final value 910,005.00 (−9.0%) — steady losses even on zero-commission M15 data. In high-frequency churn, a faint signal edge cannot survive even a sliver of friction. That losing baseline is asserted to the cent in the test file, which makes it a superb control group for studying how combination methodologies fail. + +Put the two deep dives side by side and a third lesson appears: voting and scoring both add parameters as they add indicators — the Camel system carries four periods plus a take-profit distance, the Wizard system six weights and thresholds, and the bench below goes up to seven indicators (Binary Wave) or a five-input perceptron. Every extra knob buys more power to fit history and quietly spends out-of-sample reliability. That is precisely what a regression library is for: **pin every combination's raw score into a baseline first, and force any "optimization" to compete head-to-head on identical data.** + +## The Rest of the Bench + +- **Kaufman Efficiency Ratio** (`test_0001`): ER = net displacement over path length; above 0.3 the market is worth following, and only then does the KAMA adaptive-moving-average breakout get a hearing — filter "is there a trend" before asking "which way." +- **SAR + ADX + SMA100** (`test_0027`): direction (which side of SAR) × strength (ADX > 20) × trend (above/below SMA100) — the cleanest example of dividing labor among indicators. +- **Perceptron** (`test_0028`): MA cross, RSI, CCI, momentum, and Awesome Oscillator weighted into one perceptron emitting a directional bias — scoring reduced to its neural-network minimal form. +- **Binary Wave** (`test_0029`): MA/MACD/OSMA/CCI/momentum-ratio/RSI/ADX weighted into a single smoothed wave crossing zero — parliament compressed into one curve. +- **Universum 3.0** (`test_0022`): DeMarker above/below 0.5 for direction, then martingale doubling after losses until a circuit-breaker — a cautionary tale of money management substituting for a missing edge. + +## Run It Yourself + +```bash +# The whole category (29 strategies) +pytest tests/functional/strategies/multi_indicator_system/ -v + +# Just Camel CCI MACD +pytest tests/functional/strategies/multi_indicator_system/test_0014_steve_cartwright_trader_camel_cci_macd.py -v +``` + +## Why Study Multi-Indicator Systems Here + +No category has a higher parameter density — seven or eight knobs per strategy is routine, and combinatorial sweeps quickly reach tens of thousands of backtests.

These are not marketing numbers; they are test assertions (`abs(final_value - 2875338.15) < 2.88` and friends, line after line). The honest caveat: gold itself was in a great bull market over 2008-2025, so a chunk of this is beta. The strategy's real value is as a baseline — "hold all year" versus "hold six months" — and an independent second implementation (`test_0015_0366`) lives in the same directory for cross-checking. + +## Deep Dive 2: Turn of Month — the Window as a Window Function + +The turn-of-month effect is the tendency for returns to concentrate in the last few and first few days of each month; the usual suspects are payroll/pension inflows and institutional rebalancing. This implementation ([test_0020](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/calendar_effects/test_0020_0407_turn_of_month_strategy.py)) defines the window exactly, with groupby-rank: + +```python +fwd_rank = pd.Series(range(len(out)), index=out.index).groupby(current_period).transform( + lambda x: x.rank(method='first')) +rev_rank = pd.Series(range(len(out)), index=out.index).groupby(current_period).transform( + lambda x: x.rank(ascending=False, method='first')) +out['is_month_end_window'] = (rev_rank <= last_days).astype(float) # last_days = 3 +out['is_month_start_window'] = (fwd_rank <= first_days).astype(float) # first_days = 3 +in_window = (out['is_month_end_window'] > 0.5) | (out['is_month_start_window'] > 0.5) +out['entry_signal'] = (in_window & (~prev_in_window)).astype(float) +out['exit_signal'] = ((~in_window) & prev_in_window).astype(float) +``` + +On an entry signal the strategy goes fully long via `order_target_percent(target=1.0)` and arms a 2% percentage stop: `self.stop_price = close * (1.0 - self.p.stop_loss_pct)` — the standard engineering combo of "calendar window plus risk control." The file even carries a version-compatibility lesson: pandas 3.x `fillna(False)` no longer silently downcasts object booleans, so the author explicitly keeps the object dtype so pandas 2.x and 3.x emit identical signals. + +**The backtest:** same XAUUSD daily series, 1,296 of 4,638 bars inside the window (about 28% of the time), 210 trades, 115 wins against 94 losses (54.8%), final value 2,000,333 (+100.0%), profit factor 1.50, Sharpe 0.562. Achieving that while invested less than a third of the time is precisely the turn-of-month pitch. + +## Deep Dive 3: the FOMC Effect — Events as Calendars + +Calendar effects are not only about months; they are about dates that matter. [test_0022](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/calendar_effects/test_0022_0016_gold_fomc_effect.py) studies gold drift around Federal Reserve meetings. Since a backtest cannot fetch the real FOMC calendar, it synthesizes a proxy: + +```python +FOMC_MONTHS = (1, 3, 5, 6, 7, 9, 11, 12) +# take the 3rd Wednesday of each FOMC month as the proxy date, aligned to the nearest trading day +stop_pct = float(np.clip(stop_vol_multiplier * stop_pct * math.sqrt(pre_event_days), + min_stop_pct, max_stop_pct)) # 2.0 x vol x sqrt(5), clipped to [1%, 5%] +if historical_drift > 0 and current_trend > 0: + direction = 1 # long only when historical pre-event drift and current trend agree +``` + +Position sizing is deliberately restrained: 3% notional per event (`event_position_pct=0.03`), and after three consecutive losses the system pauses for one event. **The backtest:** 69 trades, 33 wins against 36 losses, final value 994,992 (−0.50%), Sharpe −0.17, max drawdown just 1.29%. It loses money — but transparently, with tiny positions and tight stops. As a template for "testing a hypothesis that fails, at low risk," it is unmatched; positive-return companions (`test_0024` jobs-report new high, `test_0026` pre-election drift) sit in the same directory for contrast. + +## The Rest of the Bench + +- **Seasonal flip & composite** (`test_0012_0275` / `test_0013_0281`): assemble single-month effects into combined signals. +- **Commodity front-running** (`test_0019_0406`, GLD data): position ahead of seasonal demand. +- **Cultural calendar gold** (`test_0021_0412`, GLD data): windows around Chinese New Year and Diwali physical-demand seasons. +- **Rate-hike cycle gold** (`test_0023_0079`): three data sources (XAUUSD/GTIP/IEF) locate the rate cycle. +- **expert_news** (`test_0028`, XAUUSD 15-minute): the category's only intraday implementation — event-window engineering on high-frequency data. + +## Run It Yourself + +```bash +# The whole category (28 strategies) +pytest tests/functional/strategies/calendar_effects/ -v + +# Just Sell in May +pytest tests/functional/strategies/calendar_effects/test_0008_0103_sell_in_may.py -v +``` + +## Why Study Calendar Effects Here + +Calendar rules are simple and signals are sparse, which is exactly when you need infrastructure for **massive horizontal comparison**: does the proverb hold on gold, Bitcoin, and FX alike?

Prices cannot fall forever — but after nine consecutive down-closes and a further countdown of thirteen, the sellers should be tired. The repository's implementation ([test_65](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/misc/test_65_td_sequential_strategy.py)) faithfully reproduces the two-stage structure. The Setup phase: nine consecutive closes below the close four bars earlier (`candles_past_to_compare=4`): + +```python +if len(self.dataclose) > self.p.candles_past_to_compare: + # buy trigger: this close < close 4 back, and the previous bar did not qualify + if (self.dataclose[0] < self.dataclose[-self.p.candles_past_to_compare] and + self.dataclose[-1] > self.dataclose[-(self.p.candles_past_to_compare + 1)]): + self.buyTrig = True + self.sellTrig = False + # Setup count: each further qualifying bar increments + if self.dataclose[0] < self.dataclose[-self.p.candles_past_to_compare] and self.buyTrig: + self.tdsl += 1 +``` + +The Countdown phase starts once Setup reaches nine, and only at bar 13 — with price breaking the low recorded at countdown bar 8 — is the "ideal buy point" confirmed: + +```python +if self.buyCountdown == 8: + self.buyVal = countdown_compare # record bar-8 price +elif self.buyCountdown == 13: + if self.dataprimary.low[0] <= self.buyVal: + self.idealBuySig = True + if not self.position: + self.buy(size=10) # ideal buy point, go long + self.buySetup = False + self.buyCountdown = 0 +``` + +The parameters — `cancel_1/2/3`, `recycle_12`, `aggressive_countdown` — are the full vocabulary of DeMark's cancellation and recycling clauses. **The backtest:** ORCL 2010-2014, 100,000 initial, 0.1% commission; after 1,257 bars the account stands at 100,002.91 — dead flat, with Sharpe locked to six decimals (0.022949...). The test is parametrized over `runonce=True/False` and asserts identical numbers both ways. Exhaustion counting does not make money on a single stock — but as an engineering blueprint for a complex state machine under regression discipline, it is priceless. + +## Deep Dive 2: Pinkfish — the Honesty of Two Bars + +If TD Sequential is maximalism, the Pinkfish challenge ([test_46](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/misc/test_46_pinkfish_strategy.py)) is minimalism perfected: buy a 20-day high, hold exactly two bars, sell unconditionally. The entire trading logic: + +```python +def next(self): + self.bar_num += 1 + if not self.position: + if self.data.high[0] >= self.highest[0]: # current high touches the 20-day highest + self.buy() + self.inmarket = len(self) + else: + if (len(self) - self.inmarket) >= self.p.sellafter: # held 2 bars + self.sell() +``` + +Note the difference from Turtle-style breakouts: no exit channel, no stop — the exit reads the calendar, and "time's up" means go. **The backtest:** YHOO 2005-2006, 50,000 initial, fixed 100-share lots; after 484 bars the account is worth 49,739.00 — Sharpe −2.5197, roughly −0.26% annualized. Those ugly numbers are welded into the assertions. Why read it at all? Because it is the best hypothesis-testing teaching aid in the drawer: momentum entry plus a random holding period is a grinding machine in a choppy market. Would `sellafter=20` change the picture? What about a trailing stop? Change one line, and the assertions instantly quote you the price of the experiment — that is how a regression library teaches research. + +## Deep Dive 3: The Slippage Test — the Foundation Under the Drawer + +The third deep dive belongs to no trading idea, yet decides how much every other backtest can be trusted. [test_47](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/misc/test_47_slippage_strategy.py) carries a standard SMA(10/30) crossover strategy, but its reason for existence is to host the broker's slippage API: + +```python +cerebro = bt.Cerebro(stdstats=True) +cerebro.broker.setcash(50000.0) +cerebro.broker.set_slippage_perc(0.01) # 1% slippage on all trades +... +assert strat.bar_num == 482 +assert abs(final_value - 52702.98) < 0.01 +assert abs(sharpe_ratio - (7.146238384824227)) < 1e-6 +``` + +The same strategy's fills and equity under zero versus fixed/percentage slippage are asserted one by one, in both `runonce` modes. Its siblings in arms: the commission-scheme matrix (`test_54`), the data writer (`test_60`), numeric analyzer baselines for Calmar/VWR/Sharpe (`test_49/50/57`), the PSAR indicator (`test_55`), and sizer mechanics (`test_56`). They share the exact Cerebro pipeline with the strategies, so any engine change that touches fills, fees, or indicator math trips these tests before the strategy tests notice — **the misc category is not a junk drawer; it is a load-bearing wall.** + +## The Rest of the Bench + +- **BTFD trio** (`test_39` / `test_79` / `test_110`): one "buy the dip" idea in three parameterizations — dip depth, confirmation, and entry cadence — made for horizontal comparison. +- **Sky Garden** (`test_11`): an opening-pattern intraday system on Shanghai zinc minute bars; the Chinese futures session handling is ready to copy. +- **The Strategy** (`test_21`): the reference sample for 5-minute + daily dual-timeframe backtests via `resampledata`. +- **Double Sevens & up/down candles** (`test_71` / `test_85`): candle-pattern statistics, quantified. +- **cheat-on-open** (`test_40`): demonstrates the boundaries of the open-price cheat mode — know it before you use it. + +## Run It Yourself + +```bash +# The whole category (28 tests: strategies + framework verification) +pytest tests/functional/strategies/misc/ -v + +# Just TD Sequential (runonce/runnext dual-mode asserted automatically) +pytest tests/functional/strategies/misc/test_65_td_sequential_strategy.py -v +``` + +## Why Study Misc Strategies Here + +The misc category stresses an engine's corners hardest: Renko and Heikin Ashi non-standard bars, multi-timeframe alignment, slippage and commission minutiae — precisely where numerical divergence is born.

It approximates the equity leg with a single asset (gold) and the bond leg with de-risking: above SMA200 the target exposure is 60%; below it, 30% — "half off below the line" is a soft stop-loss for the whole portfolio. Signal side: + +```python +out["ma"] = out["close"].rolling(ma_period).mean() # ma_period = 200 +out["trend_up"] = (out["close"] > out["ma"]).astype(float) +# a rebalance flag is raised every rebalance_days = 63 days +``` + +On rebalance days the strategy adjusts to the trend target, and only acts when the drift exceeds 10%: + +```python +target_weight = self.p.equity_weight if trend_up else 0.30 # 0.60 / 0.30 +if abs(current_size - target_size) > target_size * 0.1: + self.pending_order = self.close() # flatten first, then resize +``` + +**The backtest:** XAUUSD daily 2008-2025 from 1,000,000 — only 19 adjustments in 17 years, 13 wins against 6 losses (68.4%), final value 2,542,114 (+154.2%), profit factor 5.24, max drawdown a modest 11.9%, Sharpe 0.770. Low frequency plus a trend filter is a drawdown-control combination that buy-and-hold cannot offer on the same series. For the unfiltered versions in a multi-asset setting, `test_0002` and `test_0003` provide the contrast. + +## Deep Dive 2: the Permanent Portfolio — 25% x 4 Philosophy + +Harry Browne proposed the Permanent Portfolio in 1981: stocks, bonds, gold, and cash at 25% each, betting that the future is always in one of four states — prosperity, recession, inflation, or deflation — and that in each state some asset thrives. The implementation ([test_0007](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/asset_allocation/test_0007_permanent_portfolio.py)) uses three daily ETF feeds (GLD/IVV/IEF) plus a cash leg: + +```python +params = dict( + target_weights={'GLD': 0.25, 'IVV': 0.25, 'IEF': 0.25}, + cash_weight=0.25, + rebalance_threshold=0.05, # drift band for ordinary assets: 5% + gold_rebalance_threshold=0.02, # gold is volatile; give it a tighter 2% +) +``` + +Rebalancing runs on dual tracks — annual plus threshold — which is standard practice for live portfolios: + +```python +if current_year != self.last_rebalance_year: + self._rebalance() # forced on the first trading day of each year + return +if self._needs_threshold_rebalance(): # drifted past the band: correct early + self.threshold_rebalance_count += 1 + self._rebalance() +``` + +**The backtest:** 2008-2025, 4,518 trading days, 50 rebalances fired — 32 of them by threshold, the gold leg's tight 2% band staying busy as designed — final value 4,268,547 (+326.9%), 8.43% annualized, max drawdown 32.3%, Sharpe 0.659. Caveat printed honestly: both gold and US equities enjoyed a mighty bull run in this window, so the headline numbers flatter the design. But details like "a tighter drift band for the gold leg" are what textbooks omit and backtests teach. + +## Deep Dive 3: CPPI — Capital Preservation by Formula + +CPPI (Constant Proportion Portfolio Insurance) is 1980s technology invented for "guaranteed funds": set a floor the portfolio must not breach, call the excess of portfolio value above the floor the cushion, and set risky exposure = cushion × multiplier. Rallies thicken the cushion and enlarge exposure; declines shrink it and de-risk automatically — in theory the floor is never pierced. The implementation ([test_0017](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/asset_allocation/test_0017_cppi_portfolio_insurance.py)): + +```python +running_max = out['close'].cummax() +floor_value = running_max * floor_pct # floor_pct = 0.8, i.e. 80% of peak +out['cushion_pct'] = (out['close'] - floor_value) / out['close'] +out['exposure'] = (out['cushion_pct'] * cppi_mult).clip(0.0, 1.0) # multiplier = 3.0 +``` + +Rebalancing every 21 days, entries only when exposure exceeds 10%, full liquidation below 5%. **The backtest:** 35 trades, 14 wins against 20 losses — a 40% win rate — yet the account finishes at 1,533,999 (+53.4%) with Sharpe 0.447. Winning less than half the time while banking profit is CPPI's personality: with a 3x multiplier, upside cushions expand exposure quickly while downside compresses the balance sheet fast. Its enemy is gap risk — one jump straight through the floor. Whether a daily-bar 20% cushion survives a 2008-style crash is an excellent experiment to run yourself by editing the parameters. + +## The Rest of the Bench + +- **HRP / HERC** (`test_0012` / `test_0015`): Lopez de Prado's answer to covariance inversion, from *Advances in Financial Machine Learning* — hierarchical clustering plus recursive bisection; stable, interpretable weights, the modern face of risk parity. +- **Dual-asset leveraged portfolio** (`test_0009`): the minimum viable allocation — one risky asset plus cash. +- **Volatility-based family** (`test_0020` / `test_0021`): switch between stocks and bonds against a volatility target. +- **Random-data portfolio optimization** (`test_0006`): the portfolio-optimization pipeline demonstrated on GDX/XAGUSD/XAUUSD. +- **Open-to-open TAA** (`test_0016`): rebalance at the open instead of the close — execution-timing sensitivity, tested. + +## Run It Yourself + +```bash +# The whole category (23 strategies) +pytest tests/functional/strategies/asset_allocation/ -v + +# Just the Permanent Portfolio +pytest tests/functional/strategies/asset_allocation/test_0007_permanent_portfolio.py -v +``` + +## Why Study Asset Allocation Here + +Allocation backtests are bottlenecked by multi-asset alignment and rebalance scheduling: decades of daily bars, several data feeds, hundreds of rebalance events, each involving cash arithmetic and multi-leg ordering.

Step one, define the log spread with a fixed hedge ratio: + +```python +def _spread(self): + gold_price = max(float(self.gold.close[0]), 1e-6) + silver_price = max(float(self.silver.close[0]), 1e-6) + return math.log(gold_price) - float(self.p.hedge_ratio) * math.log(silver_price) +``` + +Step two, a rolling z-score over 192 bars. Step three, three thresholds managing the position: + +```python +if not has_position: + if zscore <= -float(self.p.entry_threshold): # entry = 2.0, spread cheap: buy gold, sell silver + self._open_long_spread() + elif zscore >= float(self.p.entry_threshold): # spread rich: sell gold, buy silver + self._open_short_spread() + return +if abs(zscore) <= float(self.p.exit_threshold) or abs(zscore) >= float(self.p.stop_threshold): + self._close_all() # exit = 0.5 on reversion; stop = 3.0 when the spread runs away +``` + +Each leg is sized at 5% notional (`max_notional_pct=0.05`). **The backtest:** gold/silver H1 bars from July to December 2025, 2,986 bars, 102 pair trades, 46 wins against 56 losses (45.1%), final value 990,238 (−0.98%), Sharpe −1.91, max drawdown a contained 1.67%. Small sizing caps the damage, but the fixed `hedge_ratio=1.0` is the visible weak point — the gold/silver ratio's center has drifted from around 60 to 120 over two decades, and a static ratio eats that drift as a loss. Hence the second deep dive. + +## Deep Dive 2: the Kalman Filter — a Beta That Moves + +If the relationship drifts, make the hedge ratio β a state variable and estimate it online. [test_0001](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/pairs_trading/test_0001_gold_kalman_filter_pairs_trading.py) runs a one-dimensional Kalman filter, updating "how many ounces of silver per ounce of gold" bar by bar: + +```python +def update(self, price_a, price_b): + beta_pred = self.beta + P_pred = self.P + self.Q # process noise Q = 0.0005 + denominator = P_pred * price_b * price_b + self.R # observation noise R = 1.0 + K = (P_pred * price_b) / denominator # Kalman gain + innovation = price_a - beta_pred * price_b # residual = new spread information + self.beta = beta_pred + K * innovation # beta adapts to new evidence + self.P = (1.0 - K * price_b) * P_pred + spread = price_a - self.beta * price_b + return self.beta, spread +``` + +Seeded at `initial_beta=78.0` (roughly the historical ratio), it is data-driven thereafter. The masterstroke is the **beta stability gate**: entries are allowed only when the coefficient of variation of β over the last 96 bars stays under 0.03 — when the relationship is unstable, stand aside: + +```python +if self.current_zscore <= -float(self.p.entry_threshold) and is_stable: + self._submit_pair_orders(1, price_a, price_b) # entry = 2.0, exit = 0.35, stop = 3.25 +``` + +**The backtest:** the same H1 data, 103 closes (61 wins against 42 losses, 59.2%, including 9 stops), final value 997,507 (−0.25%). Against Deep Dive 1: win rate up from 45% to 59%, drawdown smaller — the value of a dynamic β is not earning more, but being wrong less. + +## Deep Dive 3: the Copula — Not Just the Spread, but "Extreme Together?" + +A z-score silently assumes the spread is elliptically distributed, but gold/silver coupling lives in the tails: in panics, gold up and silver down can be extreme simultaneously. The copula approach models the joint distribution directly ([test_0007](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/pairs_trading/test_0007_copula_pairs_trading.py)): estimate a Clayton copula parameter from Kendall's tau over a 252-day rolling window (Clayton captures lower-tail dependence), then compute "the conditional probability of silver's move, given gold's": + +```python +tau = stats.kendalltau(u, v).correlation +theta = 2.0 * tau / max(1e-6, 1.0 - tau) # tau -> theta +def clayton_conditional(u, v, theta): + term1 = u ** (-(theta + 1.0)) + term2 = (u ** (-theta) + v ** (-theta) - 1.0) ** (-(theta + 1.0) / theta) + return term1 * term2 # P(V<=v | U=u) +``` + +Read the conditional probability like this: `P(V<=v|U=u)` near zero means "gold barely moved, yet silver tanked" — silver is the mispriced leg; buy silver, sell gold, hedged by the rolling beta. The thresholds: + +```python +if prob_v_given_u < entry_threshold: # 0.05, silver distinctly cheap + position = 1 +elif prob_v_given_u > 1.0 - entry_threshold: # silver distinctly rich + position = -1 +if abs(prob_v_given_u - 0.5) <= exit_band: # 0.10, back in the neutral band: flatten + position = 0 +``` + +**The backtest:** gold/silver daily 2018-2025, 1,812 bars, 292 trades with 136 wins (46.6%), final value 986,607 (−1.34%), Sharpe −0.24. All three deep dives lost money — not by accident: in increasingly efficient markets, plain statistical arbitrage stopped printing money long ago.

The former compresses several features into one score and sets a threshold; the latter (next section) discretizes market regimes. [test_0003](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/machine_learning/test_0003_gold_ml_prediction.py) is the synthesizer's textbook exhibit — an RSI score, an MA trend score, and a volatility-rank score, averaged: + +```python +# RSI score (0-1, oversold=1) +rsi = 100 - (100 / (1 + rs)) +out['rsi_score'] = 1.0 - rsi / 100.0 + +# MA score (fast > slow = 1) +fast_ma = out['close'].rolling(ma_fast).mean() # ma_fast = 20 +slow_ma = out['close'].rolling(ma_slow).mean() # ma_slow = 60 +out['ma_score'] = (fast_ma > slow_ma).astype(float) + +# Vol score (low vol = high score) +vol = ret.rolling(vol_period).std() # vol_period = 20 +out['vol_score'] = 1.0 - vol.rolling(min(252, len(vol))).rank(pct=True) + +# Composite +out['composite_score'] = (out['rsi_score'] + out['ma_score'] + out['vol_score']) / 3.0 +``` + +The trading rule is two comparisons: `score > threshold (0.6)` buys in full; `score < 1.0 - threshold (0.4)` flattens. No model files, no random seeds — everything reproduces. On XAUUSD 2008-2025 from 1,000,000 with 0.02% commission, the asserted baseline reads: 39 trades, 20 wins against 18 losses (51.28% win rate), final value 3,334,048.03 (+233.40%), profit factor 2.451, Sharpe 0.636, max drawdown 34.93%. Notice that all three scores derive from price alone — the "ML" here is really hand-crafted feature engineering. That is precisely the regression library's taste: **interpretable, assertable, replayable.** + +## Deep Dive 2: KMeans Clustering — a 0-for-70 Lesson in Out-of-Sample + +[test_0001](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/machine_learning/test_0001_candlestick_kmeans_classification_gold.py) takes the classifier posture — and delivers the category's most honest lesson. It feeds KMeans three ratio features per bar (upper shadow, lower shadow, body, each normalized by ATR), fits on a 756-day training window, refits every 20 days, and promotes the "active cluster" whose next-day mean return beats the benchmark: + +```python +fitted_model = KMeans(n_clusters=n_clusters, random_state=42, n_init=10) # n_clusters = 4 +train_labels = fitted_model.fit_predict(train_x) +cluster_stats = train.groupby("cluster")["next_intraday_return"].agg(["mean", "count"]) +benchmark = float(train["next_intraday_return"].mean()) +eligible = cluster_stats[cluster_stats["count"] >= min_cluster_size] # min_cluster_size = 20 +if not eligible.empty and float(eligible.iloc[0]["mean"]) > benchmark: + active_cluster = float(eligible.index[0]) +``` + +When today's bar is predicted into the active cluster, the strategy buys at the next open and force-closes before the session ends. Signals are shifted with `shift(1)` to kill look-ahead. The result? On XAUUSD 2022-2025, 262 trading days, 70 trades — **zero wins, seventy losses.** The test asserts `win_count == 0` and `loss_count == 70`, nailing the shutout into the baseline. A cluster's in-sample statistical edge evaporates the moment it leaves the training window — the canonical overfitting specimen on low-signal-to-noise financial data, more vivid than any textbook lecture. (The file also demonstrates graceful degradation: without scikit-learn, the whole module skips rather than errors.) + +## Deep Dive 3: Reinforcement Learning — a q_score Is Not a Q Value + +[test_0004](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/machine_learning/test_0004_reinforcement_learning.py) has the scariest name and the tiniest core. It computes a "q_score" — the average of RSI's normalized distance from 50 and price's percentage distance from its 50-day moving average: + +```python +ma = out['close'].rolling(ma_period).mean() # ma_period = 50 +rsi_norm = (out['rsi'] - 50) / 50.0 # rsi_period = 14 +trend = (out['close'] - ma) / ma +out['q_score'] = (rsi_norm + trend) / 2.0 +``` + +Trading rules: flat and `q > 0.2` buys; long and `q < -0.2` flattens. No environment, no reward updates, no Bellman equation — it is an RL-*shaped* state-to-action mapping, not the real thing. The engineering commentary writes itself: a genuine RL backtest can hardly be made a deterministic regression (training's own randomness drifts every run), so this "frozen decision function" keeps RL's form while discarding its unreproducible soul. Its baseline is equally frank: 56 trades, 41.07% win rate, final value 1,956,006.56 (+95.60%), max drawdown 44.85%, Sharpe 0.348 — it earns a lot and shakes hard doing it. + +## The Rest of the Bench + +- **Extreme short-term gain** (`test_0002`): detect multi-day surges as "extreme events," enter on the next pullback, exit on a fixed holding period — event-driven feature engineering. +- **Random forest ratios** (`test_0005`): a real sklearn random forest classifying synthetic fundamental ratios across five ETFs; the module skips gracefully when sklearn is missing. +- **Sentiment signal** (`test_0006`): no news feed?

[cloudQuant/backtrader](https://github.com/cloudQuant/backtrader) builds the countermeasures into the infrastructure: 1,152 strategy regression tests and per-strategy asserted metric baselines record out-of-sample failures like "0 wins in 70 trades" permanently instead of letting them vanish into quiet re-tuning; the pure-Python engine runs 46% faster than the original, so feature experiments and parameter sweeps never need an overnight window; and the C++ backend (`pip install back-trader-cpp`) adds a median 128x speedup on top, with runonce/runnext dual-mode parity keeping both execution paths honest.

[test_0004_gold_cot.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/commodity_currency/test_0004_gold_cot.py) encodes it as 156-week (three-year) rolling z-scores: + +```python +out['commercial_z'] = (cot_weekly['commercial_net'] - commercial_mean) / commercial_std +out['speculator_z'] = (cot_weekly['speculator_net'] - spec_mean) / spec_std +long_entry = (out['commercial_z'] >= extreme_threshold) & (out['speculator_z'] <= -extreme_threshold) +long_exit = (out['commercial_z'] < exit_threshold) & (out['speculator_z'] > -exit_threshold) +``` + +Enter when commercials are extremely long (z ≥ +2.0) while speculators are extremely short (z ≤ −2.0); exit as both revert toward neutral (±1.0). Size scales with extremity — 3% base, 5% cap — plus a 3% stop and a "three consecutive losses, pause four weeks" cooldown. The engineering is serious too: daily XAUUSD is resampled to W-FRI weeks and aligned with COT releases (888 usable bars), the CFTC archive auto-downloaded when the local cache is missing. The result is honest: 22 trades, 36.36% win rate, final value 997,205.05 (−0.28%), profit factor 0.749. The smart-money hypothesis did not pay on twenty years of gold — and the baseline records exactly that. + +## Deep Dive 3: Real-Rate Signal — An ETF Log-Ratio Proxy + +Real rates (nominal minus inflation expectations) are the first-order variable in gold pricing. The trick in [test_0010_gold_real_rate_signal.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/commodity_currency/test_0010_gold_real_rate_signal.py): skip the macro database — a ratio of two ETFs approximates the level: + +```python +ratio = nominal['close'] / inflation['close'] # IEF / GTIP +signal_df['real_rate_proxy'] = np.log(ratio) +signal_df['real_rate_change'] = signal_df['real_rate_proxy'] - signal_df['real_rate_proxy'].shift(signal_window) +signal_df['real_rate_trend'] = signal_df['real_rate_proxy'] - signal_df['real_rate_proxy'].rolling(trend_window).mean() +... +active = rr_change < entry_threshold and rr_trend < 0 and drawdown > -stop_loss_pct +``` + +When the proxy is falling over 63 days and below its 126-day trend — gold-supportive — and gold itself is not in a deep (>8%) drawdown, exposure scales from 50% to 100% by signal strength; annualized volatility above 25% halves the target; rebalancing is monthly. Baseline over 2011-2025: 2,748 daily bars, only 10 trades, final value 1,064,691.53 (+6.47%), profit factor 1.284, max drawdown 25.10%, Sharpe 0.135.

Layer one is volatility targeting — target 12% annualized, so the higher the realized vol, the smaller the position, clipped to [0.25, 1.0]: + +```python +if current_vol > 0: + vol_position = self.p.target_vol / current_vol # target_vol = 0.12 + return max(0.25, min(1.0, vol_position)) +``` + +Layer two is the drawdown ladder — peak-to-trough drawdown `(close - cummax) / cummax` crossing each threshold steps the multiplier down (documented intent: 3%/6%/10% → 1.0/0.75/0.5/0.25): + +```python +if drawdown < -self.p.dd_threshold_1: # 0.03 + return self.p.position_level_1 # 1.0 +elif drawdown < -self.p.dd_threshold_2: # 0.06 + return self.p.position_level_2 # 0.75 +elif drawdown < -self.p.dd_threshold_3: # 0.10 + return self.p.position_level_3 # 0.5 +else: + return self.p.position_level_4 # 0.25 +``` + +The two layers combine via `min(dd_position, vol_position)`, then pass through an exponential smoother (factor 0.15) and a 5% rebalancing band — only act when the smoothed target moves more than 5%. + +**The engineering note (read this twice).** Look at the branch order above: since `drawdown` is never positive, any drawdown beyond −3% returns 1.0 immediately — the 0.75 and 0.5 tiers are unreachable, and *shallow* drawdowns fall through to `else` and get 0.25. The migration baseline locks the code's **actual behavior**, not the documentation's intent: 2008-2025, 4,618 daily bars, 289 rebalances, final value 2,732,100.12 (+173.21%), Sharpe 0.616, max drawdown 31.43%. That is precisely what asserted baselines are for — fix the ladder ordering and the test goes red, forcing the change to be reviewed and re-recorded instead of drifting silently. + +## Deep Dive 2: Tail-Risk MA Warning — the 10-Month Moving Average Switch + +After 2008, "cut exposure when price loses the 10-month moving average" graduated from futures-floor folklore to a published tail-risk mitigation model (Meb Faber's classic study used exactly the 10-month MA). [test_0003_tail_risk_ma_warning.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/risk_management/test_0003_tail_risk_ma_warning.py) replicates the rule faithfully: + +```python +monthly_close = out['close'].groupby(month_end_index).last() +monthly_ma = monthly_close.rolling(ma_period).mean() # ma_period = 10 months +monthly_risk_state = (monthly_close < monthly_ma).astype(float) +active_risk_state = monthly_risk_state.shift(1).reindex(month_end_index).fillna(0.0) +out['target_pct'] = np.where(out['risk_state'] >= 0.5, risk_position, normal_position) # 0.5 / 1.0 +``` + +Three details show the craft: daily bars are grouped to month-end closes so the signal has monthly granularity; `shift(1)` delays the regime by one month — last month's close below the MA cuts *this* month's exposure, killing any lookahead; and a 2% rebalancing band stops the target from churning orders at the boundary. Over 2008-2025: 216 calendar months, 68 in the risk state (31.48%), 32 regime switches. Of 24 "large-loss months" (≤ −5%), 16 (66.67%) occurred below the MA — the switch really did keep most of the worst months out. Final value 3,806,875.01 (+280.69%), Sharpe 0.555, max drawdown 39.41% — against gold's 2011-2015 bear market, halving exposure could soften but not immunize. + +## The Rest of the Bench + +- **Risk on / risk off** (`test_0008`): the phrase compressed to one AND — annualized vol below 20% AND price above the 100-day MA. 81 trades, only 23 wins (28.40%) yet profit factor 3.75: classic regime filtering, mostly small stops plus a few large trends. Final value 3,881,633.30 (+288.16%), Sharpe 0.746, SQN 2.27, max drawdown 19.44% — the best drawdown control of the lot. +- **Probit risk modeling** (`test_0001`): a probit regression estimates the probability of a near-term crash; above threshold, go flat — a statistical model used as a circuit breaker. +- **Multi-market hedge / Crisis hedge** (`test_0002/0007`): a gold-long/miner-short relative-value book, and a system that buys gold specifically in crash regimes to harvest crisis alpha. +- **Bond risk premium / Managed futures hedge / Risk premium value** (`test_0005/0006/0009`): stock-bond de-risking, a CTA-style trend switch, and return-per-volatility scoring — three classic institutional recipes. +- **Grid delta hedge** (`test_0010`): a symmetric grid whose target exposure steps per crossing, with periodic re-centering. +- **The MA family (test_0011-0019)**: full disclosure — nine EA ports (0040/0150/0300/0375/0407/0705/1120/1273/1276) filed under this category by source; they carry no risk logic of their own.

The test pins that result with `abs(final_value - 99965.62) < 0.01`. That is the point of a regression library: strategies are here **to be compared, not performed**. A naked breakout bleeds in choppy markets; later articles in this series show how a single ADX filter or volume confirmation transforms the same idea. + +## Deep Dive 2: Dual Thrust — the Futures Intraday Workhorse + +Dual Thrust ([test_09](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/breakout/test_09_dual_thrust_strategy.py)) runs on glass-futures minute bars in three steps. + +**Step 1 — build a range from the last N days (default 10):** + +```python +hh = max(day_high_list[-look_back:]) # N-day high +lc = min(day_close_list[-look_back:]) # N-day lowest close +hc = max(day_close_list[-look_back:]) # N-day highest close +ll = min(day_low_list[-look_back:]) # N-day low +range_price = max(hh - lc, hc - ll) # the more conservative of the two +``` + +**Step 2 — anchor two trigger lines at today's open:** + +```python +upper_line = now_open + k1 * range_price # k1 = 0.5 +lower_line = now_open - k2 * range_price # k2 = 0.5 +``` + +**Step 3 — trade the touch, reverse on the opposite band, flatten at 14:55.** + +The elegance: bands anchored at the open adapt to where each day starts, while the Range scales with volatility — wilder markets automatically get wider bands and fewer fake signals. The test also encodes the real rhythm of Chinese futures sessions (night session 21:00-23:00, day session 09:00-11:00). + +## Deep Dive 3: R-Breaker — One Ladder of Levels, Two Playbooks + +If Dual Thrust is a one-way pursuer, R-Breaker ([test_10](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/breakout/test_10_r_breaker_strategy.py)) is a double agent — **trend and reversal in one system**, a long-time resident of intraday strategy rankings. + +From yesterday's high (H), low (L), and close (C): + +```python +pivot = (pre_high + pre_low + pre_close) / 3 +r1 = pivot + 0.5 * (pre_high - pre_low) # observation resistance +r3 = pivot + 1.0 * (pre_high - pre_low) # breakout resistance +s1 = pivot - 0.5 * (pre_high - pre_low) # observation support +s3 = pivot - 1.0 * (pre_high - pre_low) # breakout support +``` + +Two rule sets share the ladder: + +- **Trend mode:** from flat, a close above R3 → go long; below S3 → go short (strong breakouts continue); +- **Reversal mode:** long positions that fall back through R1 are closed **and reversed** to short; shorts rising through S1 are reversed to long. + +Flatten everything at 14:55. The trend mode harvests follow-through; the reversal mode punishes failed breakouts — whichever script the day follows, R-Breaker has a plan. On the engineering side, the test prices rebar with `ComminfoFuturesPercent` (10% margin, 10x multiplier) from 50,000 cash — a ready-made template for margin-aware futures backtests. + +## The Rest of the Bench + +- **Volume breakout** (`test_115`): a breakout must be *heard* — entry requires volume well above its moving average; exits on RSI overbought or a max holding period. +- **Price channel** (`test_117`): the minimal Turtle variant — enter at an N-day high, exit at an M-day low.

This article dives into those three sources. + +## Category at a Glance + +| Strategy | Data | Core idea | Source | +|----------|------|-----------|--------| +| Keltner multi-contract | Rebar futures, multi-contract | Channel breakout both ways + auto rollover to the dominant contract | `test_08_kelter_strategy.py` | +| MACD + ATR | YHOO daily 2005-2014 | MACD cross entry, ATR trailing stop protection | `test_36_macd_atr_strategy.py` | +| Keltner (backhacker) | ORCL daily 2010-2014 | EMA mid ± 2×ATR, upper-band entry, mid-band exit | `test_70_keltner_channel_strategy.py` | +| SuperTrend | ORCL daily 2010-2014 | ATR(10)×3 dynamic line, trade the flip | `test_81_supertrend_strategy.py` | +| SuperTrend indicator | ORCL daily 2010-2014 | Same idea, alternate parameterization | `test_88_supertrend_indicator_strategy.py` | +| Adaptive SuperTrend | ORCL daily 2010-2014 | Multiplier self-adjusts with ATR | `test_89_adaptive_supertrend_strategy.py` | +| Keltner channel | ORCL daily 2010-2014 | Detailed companion implementation (same baseline as test_70) | `test_108_keltner_channel_strategy.py` | +| Chandelier exit | ORCL daily 2010-2014 | SMA8/15 cross + 22-day high − 3×ATR stop | `test_111_chandelier_exit_strategy.py` | +| SuperTrend + RSI | ORCL daily 2010-2014 | Enter only above the line AND with RSI confirmation | `test_114_supertrend_rsi_strategy.py` | + +## Deep Dive 1: SuperTrend — A Channel That Flips + +SuperTrend is the minimal form of a channel: draw no upper and lower bands, keep only **the one line on the trend side** — below price in an uptrend (support at ATR×multiplier), above it in a downtrend (resistance). When price crosses, the line jumps to the other side and the trend is declared reversed. The trading logic of [test_81_supertrend_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/volatility/test_81_supertrend_strategy.py) fits in one glance: + +```python +params = dict( + stake=10, + period=10, # ATR period + multiplier=3.0, # ATR multiple +) + +def next(self): + self.bar_num += 1 + if self.order: + return + + # Buy when trend turns up + if not self.position: + if self.supertrend.direction[0] == 1 and self.supertrend.direction[-1] == -1: + self.order = self.buy(size=self.p.stake) + else: + # Sell when trend turns down + if self.supertrend.direction[0] == -1: + self.order = self.sell(size=self.p.stake) +``` + +Buy the bar where direction flips from −1 to +1; sell it all when it flips back. Entry and exit are the same event — naturally symmetric, no separate stop rule needed, because the stop *is* the SuperTrend line. The baseline is honest: ORCL 2010-2014, $100,000 initial, 0.1% commission, 1,247 bars, final value 99,999.23 — flat-to-slightly-negative, Sharpe −0.0038, max drawdown 11.22%. A naked SuperTrend gets whipsawed on a chop-heavy stock, which is exactly the gap `test_114`'s RSI filter fills later. + +## Deep Dive 2: Keltner Channel — Bollinger Bands with ATR Inside + +The one-sentence difference from Bollinger Bands in [test_108_keltner_channel_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/volatility/test_108_keltner_channel_strategy.py): **Bollinger uses the standard deviation of closes; Keltner uses ATR.** Standard deviation sees only the close-to-close distribution and can "pinch" misleadingly in quiet markets; ATR counts highs, lows, and gaps, so the band width tracks true volatility. The channel is an EMA midline with bands offset by 2×ATR: + +```python +params = dict( + stake=10, + period=20, # EMA period + atr_mult=2.0, # ATR multiplier +) + +def next(self): + self.bar_num += 1 + if self.order: + return + + if not self.position: + # close breaks the upper band: bullish momentum confirmed + if self.data.close[0] > self.kc.top[0]: + self.order = self.buy(size=self.p.stake) + else: + # falls back to the mid line (EMA): trend fading, exit + if self.data.close[0] < self.kc.mid[0]: + self.order = self.close() +``` + +Note the asymmetry: entry demands a break of the *upper* band (only strong moves count), but exit only requires falling back to the *middle* — room for the trade to breathe without waiting for a full lower-band breach. Baseline: ORCL 2010-2014, 1,238 bars, final value 100,039.51, Sharpe 0.2796, max drawdown just 5.50% — one of the best drawdown profiles in the category. `test_70` implements the identical idea with a different parameterization and asserts the exact same numbers (100,039.51 / 0.2796), forming a tidy "same rules, two implementations, mutual confirmation" pair. + +## Deep Dive 3: Chandelier Exit — the Stop That Hangs from the Ceiling + +Chuck LeBeau's chandelier exit generates no entries; it answers one question: **when does a trend position go back to the market?** The answer: a trailing stop at the highest high since entry minus N×ATR, hanging from the ceiling like its namesake, never descending. [test_111_chandelier_exit_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/volatility/test_111_chandelier_exit_strategy.py) welds it onto a moving-average cross: + +```python +params = dict( + stake=10, + sma_fast=8, # fast MA + sma_slow=15, # slow MA + ce_period=22, # chandelier lookback + ce_mult=3, # ATR multiplier +) + +def next(self): + self.bar_num += 1 + if self.order: + return + + if not self.position: + # SMA golden cross AND price above Chandelier Short + if self.sma_fast[0] > self.sma_slow[0] and self.data.close[0] > self.ce.short[0]: + self.order = self.buy(size=self.p.stake) + else: + # SMA death cross AND price below Chandelier Long + if self.sma_fast[0] < self.sma_slow[0] and self.data.close[0] < self.ce.long[0]: + self.order = self.close() +``` + +Entry needs the golden cross AND price above the short chandelier line (healthy volatility structure); exit needs the death cross AND price below the long line — timing and volatility protection must deteriorate together. Baseline: 1,235 bars, final value 100,018.36, Sharpe 0.1430, max drawdown 8.41%. A 22-day lookback with 3×ATR is exactly the magnitude LeBeau recommended — the source code *is* the literature. + +## The Rest of the Bench + +- **SuperTrend + RSI** (`test_114`): one momentum filter transforms the naked SuperTrend — final value 100,085.04, Sharpe 0.8988, the category's best. One filter was worth that much. +- **SuperTrend indicator / Adaptive** (`test_88/89`): two variants of the same idea, final values 99,977.89 and 99,936.86 — a self-adjusting multiplier did not automatically help. +- **Keltner multi-contract** (`test_08`): channel breakout on Chinese rebar futures with automatic rollover to the dominant contract — channel thinking meets real contract-expiry plumbing. +- **MACD + ATR** (`test_36`): 46 trades on YHOO (17 wins, 28 losses); contrarian MACD entries protected by an `atr * atrdist` trailing stop — the stop engineering outshines the signal. + +## Run It Yourself + +```bash +# The whole category (9 strategies, each asserted in runonce AND runnext modes) +pytest tests/functional/strategies/volatility/ -v + +# Just SuperTrend +pytest tests/functional/strategies/volatility/test_81_supertrend_strategy.py -v + +# Just the Chandelier Exit +pytest tests/functional/strategies/volatility/test_111_chandelier_exit_strategy.py -v +``` + +All 9 tests here are parametrized with `@pytest.mark.parametrize("runonce", [True, False])` — vectorized and event-driven engines each replay every backtest and must agree digit-for-digit, so a single indexing slip in the ATR rolling window or the channel carry cannot hide. + +## Why Study Volatility Channels Here + +Channel strategies are the best touchstone for a backtesting engine: rolling ATR windows, recursive band carries, flip-point boundary logic — everywhere the vectorized and event-driven paths can disagree. [cloudQuant/backtrader](https://github.com/cloudQuant/backtrader) bets heavily on exactly that: runonce/runnext dual-mode parity plus per-strategy asserted baselines across 1,152 strategy regression tests — change the multiplier from 3.0 to 2.5 and the curve's move is immediately visible against a pinned baseline. The pure Python engine is 46% faster than the original; with the C++ backend (`pip install back-trader-cpp`) and its median 128x speedup, a two-dimensional grid of ATR period × multiplier sweeps in minutes. + +Find it useful?

The most legendary is Larry Williams: in the 1987 Robbins World Cup Trading Championship he turned $10,000 into over a million dollars, an 11,000%+ year; his daughter (later the actress Michelle Williams) won the same contest at 16.

Williams' 1985 answer in *Technical Analysis of Stocks & Commodities* was surgical — **blend three periods into one indicator**, weighting the shortest most heavily: + +```python +params = dict( + stake=10, + p1=7, + p2=14, + p3=28, + oversold=30, + overbought=70, +) + +def __init__(self): + self.uo = bt.indicators.UltimateOscillator( + self.data, p1=self.p.p1, p2=self.p.p2, p3=self.p.p3 + ) + +def next(self): + self.bar_num += 1 + if self.order: + return + + if not self.position: + # Entry: UO in oversold territory + if self.uo[0] < self.p.oversold: + self.order = self.buy(size=self.p.stake) + else: + # Exit: UO in overbought territory + if self.uo[0] > self.p.overbought: + self.order = self.close() +``` + +That is the entirety of [test_109_ultimate_oscillator_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/multi_indicator/test_109_ultimate_oscillator_strategy.py) — under 20 lines. Note the `bar_num` assertion of **1,229**, some 20-26 bars fewer than its siblings: the UO needs full history for 28-period buying pressure and true range, so a longer warm-up is the inherent tax of multi-period blending. + +It posts the brightest report card of the textbook group: final value 100,199.75, Sharpe 2.2256, max drawdown just 6.37%. Against SAR's Sharpe 0.158 and 14.47% drawdown, the multi-period weighting genuinely earns its noise reduction — though the 0.04% annualized return also reminds you that an overbought/oversold system without a trend filter wins only "respectably." + +## Deep Dive 2: Stochastic KD — Adding a Location Gate to Crossovers + +George Lane's 1950s stochastic observes where the close sits inside its recent range: closing at the highs is strength, at the lows weakness. But raw K/D crossovers fire far too often, and the textbook patch is to **buy only in the oversold zone, sell only in the overbought zone**. [test_103_stochastic_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/multi_indicator/test_103_stochastic_strategy.py) implements the rule faithfully: + +```python +def __init__(self): + self.stoch = bt.indicators.Stochastic( + self.data, + period=self.p.period, + period_dfast=self.p.period_dfast, + ) + self.crossover = bt.indicators.CrossOver(self.stoch.percK, self.stoch.percD) + +def next(self): + self.bar_num += 1 + if self.order: + return + + if not self.position: + # K crosses above D and in oversold zone + if self.crossover[0] > 0 and self.stoch.percK[0] < self.p.oversold: + self.order = self.buy(size=self.p.stake) + else: + # K crosses below D and in overbought zone + if self.crossover[0] < 0 and self.stoch.percK[0] > self.p.overbought: + self.order = self.close() +``` + +Parameters are the classic 14/3 with 20/80 thresholds. The double gate — crossover AND location — compresses 1,239 bars of trading into a handful of high-quality windows: final value 100,219.02, Sharpe 0.692, max drawdown 8.50%. The engineering lesson is `CrossOver`: it pushes the boundary arithmetic (yesterday ≤, today >) down into the indicator layer, so the strategy reads a single sign — better readability, fewer bugs than hand-rolled comparisons. + +## Deep Dive 3: Parabolic SAR — Wilder's One-Book Legacy + +J. Welles Wilder Jr.'s 1978 *New Concepts in Technical Trading Systems* is probably the single most productive book in technical analysis history: RSI, ATR, ADX, and parabolic SAR all came from it. SAR's twist is the **acceleration factor** — each new trend extreme ratchets the stop tighter, faster, like a parabola, until profit is squeezed out. [test_106_parabolic_sar_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/multi_indicator/test_106_parabolic_sar_strategy.py): + +```python +params = dict( + stake=10, + af=0.02, + afmax=0.2, +) + +def __init__(self): + self.sar = bt.indicators.ParabolicSAR( + self.data, af=self.p.af, afmax=self.p.afmax + ) + self.crossover = bt.indicators.CrossOver(self.data.close, self.sar) + +def next(self): + self.bar_num += 1 + if self.order: + return + + if not self.position: + if self.crossover[0] > 0: + self.order = self.buy(size=self.p.stake) + else: + if self.crossover[0] < 0: + self.order = self.close() +``` + +af starting at 0.02 and capped at 0.2 are Wilder's original numbers. SAR is elegant — the stop is the signal — but its weakness is equally famous: getting slapped back and forth in range-bound markets. The backtest is honest about it: final value 100,044.47, Sharpe 0.158, max drawdown 14.47% over 1,255 bars — a whole lot of work for nothing. The module's own docstring says it plainly: SAR is strongest in trending markets; add a filter for chop. + +## The Rest of the Bench + +- **Williams %R** (`test_102`): Larry Williams, 1973 — same "where does the close sit in the range" idea as KD, traded as a one-sided swing: final value 100,102.86, Sharpe 0.479. +- **CCI** (`test_104`): Donald Lambert's 1980 commodity-cycle oscillator — price deviation from its typical price over mean absolute deviation, traded at ±100 crossings. +- **TRIX** (`test_107`): Jack Hutson's triple-EMA rate of change — three low-pass filters deep, zero-line crossings; the bluntest and most noise-resistant momentum indicator in the batch. +- **The Aberration twins** (`test_12` / `test_25`): blue-blooded long-term channel systems — 200-period Bollinger bands, 2 standard deviations, long the upper break, short the lower, exit at the midline. The futures version on rebar minute bars: 94 trades, Sharpe 0.55, final value 1,079,820 from 1,000,000. The stock version on 22 years of SPDB: 423,916.71 from 100,000 — with a 46.5% max drawdown. Same idea transplanted across markets, wildly different risk portraits. +- **UDVD** (`test_95`): the simplest seat — long when the 3-bar SMA of candle bodies is positive, flat when negative. Final value 99,939.44, the group's only loser: "simpler" does not mean "better." + +## Run It Yourself + +```bash +# The whole category (9 strategies, runonce/runnext parity asserted automatically) +pytest tests/functional/strategies/multi_indicator/ -v + +# Just the Ultimate Oscillator +pytest tests/functional/strategies/multi_indicator/test_109_ultimate_oscillator_strategy.py -v +``` + +## Why Study Classic Indicators Here + +Classic indicators, with few parameters and transparent formulas, are perfect for **reproducible controlled experiments**: same data, same cash settings, nine indicators, one leaderboard.

The signal side of [test_0009_1198_martgreg.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/grid_trading/test_0009_1198_martgreg.py) is not grid-like at all: two MACDs on the median price `(high+low)/2` (fast 5/20, slow 10/15, signal 3) require the fast line to turn from a local trough with slow-line confirmation; every trade carries a 500-point stop and a 1,500-point target.

The result: 687 trades, only a 35.66% win rate, but the 1,500-to-500 payoff ratio (plus the capped doubling) delivers final value 1,032,971.20 (+3.30%) with a 5.14% max drawdown — low win rate, high payoff, the opposite end of the martingale spectrum from VR-SETKA-3. + +## Deep Dive 3: Truly Random Robot — Why a Coin Flip Also Doesn't Lose + +The category's most heterodox asset is its random trio, led by [test_0008_1196_random_robot.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/grid_trading/test_0008_1196_random_robot.py): no indicator whatsoever; when flat, flip a coin (fixed `seed=1`) for direction, then place a 3,000-point stop and a 1,000-point target: + +```python +self.last_coin_toss = self.rng.randint(0, 1) +if self.last_coin_toss == 0: + self.order = self.buy(size=self.p.lot) + return +self.order = self.sell(size=self.p.lot) +``` + +909 trades, 66.23% win rate, final value 1,005,472.40 (+0.55%), max drawdown 0.56%. Why does a random strategy belong in a regression library? Because it is the **control group**. Any sophisticated strategy on this data must first beat "coin flip plus asymmetric exits" — if an indicator system can't, its intelligence is suspect. RndTrade (`test_0006`, direction re-randomized every 60 minutes, expected return near zero) and New_Random (`test_0007`, symmetric 50-point stop and target) complete the family as internal controls — random direction, asymmetric payoff, fixed cadence, each perturbation isolated.

But in spot FX and gold the aphorism needs a patch: there is **no central exchange**, hence no unified traded volume. What MT5 offers instead is tick volume — the number of quote updates inside each bar. Empirical research has long supported an interesting conclusion: tick volume correlates strongly enough with real volume to play the role. So the question becomes — what happens when you feed tick volume into classic indicators? + +The 7 strategies in `tests/functional/strategies/volume_system/` answer it.

A high-volume breakout leaves a deep mark on the VWMA; low-volume chop barely moves it. That is exactly the mechanism [test_0004_volume_weighted_ma.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/volume_system/test_0004_volume_weighted_ma.py) uses to catch turning points — and the signal is a **slope flip**, not a price crossover: + +```python +self.indicator = bt.indicators.VolumeWeightedMAIndicator(self.signal_data, length=self.p.length, ipc=self.p.ipc, use_tick_volume=self.p.use_tick_volume) +``` + +```python +v0 = self._val(self.indicator.vwma, signal_bar) +v1 = self._val(self.indicator.vwma, signal_bar + 1) +v2 = self._val(self.indicator.vwma, signal_bar + 2) +if v1 < v2: + if self.p.buy_pos_open and v0 > v1: + buy_open = True + if self.p.sell_pos_close: + sell_close = True +if v1 > v2: + if self.p.sell_pos_open and v0 < v1: + sell_open = True + if self.p.buy_pos_close: + buy_close = True +``` + +Three H4 VWMA values (`length=12`, tick-volume weighted) must trace a V — falling, then rising — to open long; an inverted V opens short. Positions carry a 1,000-point stop and a 2,000-point target enforced on the M15 execution feed. Note the `use_tick_volume=True` switch: MT5 exports carry both tick and real volume columns, and spot gold's real volume is perennially zero — this whole family defaults to the tick column, and mixing up the two is the most common migration bug. The backtest produced 54 trades at a 42.59% win rate, profit factor 1.154, final value 1,000,646.80 — another low-win-rate, payoff-ratio specimen: slope-turn signals lag by construction, so entries are not cheap; the edge is that once an H4 trend does form, the 2,000-point target dwarfs the 1,000-point stop. Engineering note: the `_last_signal_len` latch evaluates each signal bar exactly once — without it in a dual-timeframe setup, one H4 bar gets consumed 16 times by M15 bars and the signals degenerate into noise. + +## Deep Dive 2: Ergodic TVI — Blau's Multiple-Smoothing Philosophy + +In the 1990s William Blau (*Momentum, Direction, and Divergence*) systematized the "Ergodic" family: pass any raw quantity through **double exponential smoothing** before building an oscillator. The TVI (Tick Volume Index) is his recipe applied to tick volume, and [test_0006_ergodic_ticks_volume_indicator.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/volume_system/test_0006_ergodic_ticks_volume_indicator.py) lays out the whole pipeline: + +```python +up_ticks = (vol + (frame['close'].astype(float) - frame['open'].astype(float)) / point) / 2.0 +down_ticks = vol - up_ticks + +ema_up = apply_ma(up_ticks, xlength1, xma_method) +ema_down = apply_ma(down_ticks, xlength1, xma_method) +dema_up = apply_ma(ema_up, xlength2, xma_method) +dema_down = apply_ma(ema_down, xlength2, xma_method) + +denom = (dema_up + dema_down).replace(0.0, np.nan) +tvi_calculate = 100.0 * (dema_up - dema_down) / denom +tvi = apply_ma(tvi_calculate, xlength3, xma_method) +ema_tvi = apply_ma(tvi, xlength4, xma_method) +ergodic_tvi = apply_ma(ema_tvi, xlength5, xma_method) +ergodic_signal = apply_ma(ergodic_tvi, xlength6, xma_method) +``` + +The first step is the elegant one: a bullish bar's (close>open) ticks are all credited to the bulls, bearish bars to the bears, the count split in two and each side double-smoothed (`xlength1=xlength2=12`) — **tick volume is promoted into a bull-vs-bear force ratio**. TVI = 100×(up−down)/(up+down), then four more smoothing passes produce the ergodic line and its signal; crossovers trade. The six `xlength` knobs map to the six pipeline stages, with `xlength3=1` meaning TVI itself gets no extra smoothing — Blau's own trade-off point on the "deeper smoothing, duller signal" curve. Signal sparsity is the price: the whole H6 window holds only 236 bars and produced 14 trades (8 wins, 6 losses), profit factor 2.04, final value 1,005,203.90, max drawdown 0.34%. Few signals, clean curve. + +## The Rest of the Bench + +- **VWMA Candle** (`test_0001`): uses VWMA values as synthetic open/close to paint candles; flip the color, reverse the position — the pattern-reading version of the same idea. +- **VWMA Digit System** (`test_0002`): rounds VWMA highs/lows into a channel; closes beyond the rails light up color codes processed as breakout signals. +- **VWMA StDev** (`test_0003`): VWMA's bar-to-bar change divided by its rolling standard deviation — momentum as a volatility-normalized z-score with 1.5σ/2.5σ tiers. +- **Ergodic OSMA** (`test_0005`): the same TVI pipeline as Deep Dive 2 but signals on OSMA-histogram turns on H8 — a controlled comparison of "crossover" vs "inflection" signal extractors. +- **XPVT** (`test_0007`): the Price-Volume Trend ledger — each bar adds `volume × price change rate`, so a 1% rise on heavy volume moves the line more than a 5% rise on thin volume; the signal line is a 5-bar EMA of PVT. The category's best report card: 49 trades, 48.98% win rate, profit factor 3.26, final value 1,015,722.30 (+1.57%), max drawdown 0.19%.

The hypothesis of [test_0002_night_flat_trade.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/time_session_system/test_0002_night_flat_trade.py): **late at night the book thins, price compresses into a box, and the edges mean-revert**. M1 bars execute; `resampledata` builds an H1 signal feed; signals are evaluated only inside the two-hour window around `open_hour` (configured as 0:00): + +```python +hour = signal_dt.hour +if hour < int(self.p.open_hour) or hour > int(self.p.open_hour) + 1: + return +if self.position: + return + +highs = [float(self.data1.high[-i]) for i in range(3)] +lows = [float(self.data1.low[-i]) for i in range(3)] +highest = max(highs) +lowest = min(lows) +diff = highest - lowest + +pip = self._pip_value() +diff_min = float(self.p.diff_min_pips) * pip +diff_max = float(self.p.diff_max_pips) * pip +if not (diff > diff_min and diff < diff_max): + return +``` + +Three gates fall in sequence: the clock, then a channel from the **previous 3 H1 bars'** highs and lows, then the channel width must sit between 100 and 400 pips — too narrow has no meat, too wide isn't consolidation. Entries are precise to the quadrant: + +```python +if bid > lowest and bid <= lowest + diff / 4.0: + sl = lowest - diff / 3.0 + tp = ask + float(self.p.take_profit_pips) * pip if int(self.p.take_profit_pips) > 0 else None +``` + +Price in the **lower quadrant** buys, with the stop a third of the channel below the floor (`lowest − diff/3`); the upper quadrant sells symmetrically. Exits use a 50-pip fixed target plus 15/5-pip trailing protection. Sizing is equally deliberate: fixed `lots=0.1`, or derived from `risk=5.0%` and `margin_per_lot=1000` — the risk budget written into the position formula, not guessed. The honest cost is selectivity: over the five-day window (2026-03-05 to 03-10, 4,562 M1 bars) exactly **one** short trade triggered — profitable, final value 1,000,061.30. It demonstrates two things at once: how session filters and volatility gates work, and how meaningless any win rate becomes when the sample is one trade. + +## Deep Dive 2: OpenTime — the Clock, and Nothing Else + +Strip time-session trading to its skeleton and you get [test_0003_opentime.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/time_session_system/test_0003_opentime.py).

The `_window_key` — a date-plus-time string — prevents duplicate opens inside one window. One more detail deserves a circle: at load time every bar's timestamp is shifted forward 15 minutes so bars are stamped at their **close**, meaning the configured 18:45 refers to "this M15 bar closes at 18:45." The classic pitfall of session-strategy ports is the source EA and the backtest engine disagreeing about timestamp semantics — off by one bar, and every open time drifts with it. Over the three-month window: 67 trades, 37 wins / 30 losses (55.2% win rate), profit factor 1.53, final value 1,002,199.70. A fixed two-hour nightly gold short earning that says the evening drift in this data leaned downward — and note that it is simultaneously **a hypothesis test with almost no degrees of freedom**: no indicator, nothing to tune, the answer to "should this hour be shorted?" is printed in plain sight. `Exp_TimesDirection` (`test_0006`) and `Open Close on Time` (`test_0007`) are its near kin, differing only in window-detection details — side by side they form a controlled experiment isolating that one variable. + +## The Rest of the Bench + +- **21hour** (`test_0004`): a steadier variant — schedule the formation, let price pick the direction.

Writing feature verification as full strategy backtests with asserted metric baselines guards numerical drift far better than isolated unit tests. + +## Category at a Glance + +| Strategy | Data | Core idea | Source | +|----------|------|-----------|--------| +| Timer scheduling | Daily 2005-2006 (with sessions) | Dual MA cross + `SESSION_START` timer firing checks | `test_62_timers.py` | +| Pandas loading | Daily 2005-2006 | `PandasData` feeds a DataFrame straight into Cerebro | `test_52_data_pandas.py` | +| Resampling | Daily → weekly | `resampledata` aggregates weekly bars + dual MA cross | `test_53_data_resample.py` | +| Data replay | Daily → weekly | `replaydata` advances a "growing" weekly bar day by day | `test_58_data_replay.py` | +| Replay × Bollinger | Daily → weekly | Bollinger breakout on replayed weekly bars | `test_118_data_replay_bollinger.py` | +| Replay × EMA | Daily → weekly | EMA(12,26) crossover on replayed weekly bars | `test_119_data_replay_ema.py` | +| Replay × MACD | Daily → weekly | MACD(12,26,9) crossover on replayed weekly bars | `test_120_data_replay_macd.py` | + +## Deep Dive 1: Timers — Writing "Do This at 9:00" into the Strategy + +What live strategies need most is not a smarter indicator but **scheduling**: pull quotes at 9:25, rebalance before Friday's close, flatten overnight exposure at 14:55. backtrader's answer is registering timers inside the strategy and receiving callbacks in `notify_timer` ([test_62_timers.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/time_based/test_62_timers.py)): + +```python +class TimerStrategy(bt.Strategy): + params = dict( + when=bt.timer.SESSION_START, + timer=True, + fast_period=10, + slow_period=30, + ) + + def __init__(self): + self.fast_ma = bt.ind.SMA(period=self.p.fast_period) + self.slow_ma = bt.ind.SMA(period=self.p.slow_period) + self.crossover = bt.ind.CrossOver(self.fast_ma, self.slow_ma) + + if self.p.timer: + self.add_timer(when=self.p.when) + + def notify_timer(self, timer, when, *args, **kwargs): + self.timer_count += 1 +``` + +The data feed declares a trading session (`sessionstart=9:00, sessionend=17:30`), so the timer knocks at the open of every trading day. The baseline the test pins is telling: `timer_count == 512` while `next()` was only called **482 times** — the difference is exactly the 30 warm-up bars of the slow MA. In other words, **timers fire from the very first bar, without waiting for indicators to be ready**. In production terms: risk checks and data sync during warm-up never miss a day. The same run also asserts a final value of 104,966.80, Sharpe 0.721, max drawdown 3.43%, and 9 completed trades. + +## Deep Dive 2: Data Replay — Revisiting the Afternoon When the Bar Wasn't Finished + +Resampling *compresses* history; replay *re-enacts* it. With the same daily file, `replaydata` runs the strategy on a weekly timeframe but **advances once per incoming daily bar**: you watch a weekly candle that grows through the week — half-formed on Monday's close, complete only on Friday's ([test_58_data_replay.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/time_based/test_58_data_replay.py)): + +```python +# Use replay functionality to replay daily data as weekly data +cerebro.replaydata( + data, + timeframe=bt.TimeFrame.Weeks, + compression=1 +) + +cerebro.addstrategy(ReplayMAStrategy, fast_period=5, slow_period=15) + +print("Starting backtest...") +results = cerebro.run(runonce=runonce, preload=False) +``` + +Compare the same 5/15 parameters. Under resampling the strategy sees **89 weekly bars** and makes 3 trades (final value 100,765.01, Sharpe 1.079). Under replay the same strategy is advanced **439 times**, makes 13 trades, and finishes at 108,263.90 with Sharpe 1.179. Why? Replayed indicators recompute on every daily bar, so a crossover can trigger *mid-week*. That is precisely the point of replay: **testing how a strategy behaves with no future data and only a half-built bar**. It is also why replay must run with `preload=False`, feeding bars one at a time — a natural stress test of the engine's slow path. + +## The Rest of the Bench + +- **Pandas loading** (`test_52`): not all data lives in CSV files. `pd.read_csv` into a DataFrame, then `bt.feeds.PandasData(dataname=dataframe)` — the last mile from research notebook to backtest is often just this one line. Baseline: 482 bars, 9 trades, final value 100,496.68, matching the CSV-direct run. +- **Replay × Bollinger** (`test_118`): a Bollinger breakout replayed on weekly bars — 419 advances, 2 trades. +- **Replay × EMA** (`test_119`): EMA(12,26) crossover under replay — 384 advances, 9 trades. +- **Replay × MACD** (`test_120`): MACD(12,26,9) under replay — 344 advances, Sharpe 1.323, confirming a third indicator family doesn't drift on replayed data. + +## Run It Yourself + +```bash +# The whole category (7 strategies, runonce/runnext parity asserted automatically) +pytest tests/functional/strategies/time_based/ -v + +# Just data replay +pytest tests/functional/strategies/time_based/test_58_data_replay.py -v +``` + +## Why Study Time and Data Flow Here + +Timers, resampling, and replay all manipulate the engine's timeline — be off by a single bar anywhere and everything downstream is wrong.

Rather than predict, follow — [test_18_etf_rotation_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/special/test_18_etf_rotation_strategy.py) turns "relative strength" into one comparable number via a 20-day moving average: + +```python +# If both ETFs are below moving averages, close all positions +if sz_close < self.sz_ma[0] and cy_close < self.cy_ma[0]: + if self.sz_pos > 0: + self.close(sz_data) + if self.cy_pos > 0: + self.close(cy_data) + +# If at least one ETF is above its moving average +if sz_close > self.sz_ma[0] or cy_close > self.cy_ma[0]: + # If SSE 50 momentum indicator is larger + if sz_close / self.sz_ma[0] > cy_close / self.cy_ma[0]: + if self.sz_pos == 0 and self.cy_pos == 0: + total_value = self.broker.get_value() + lots = int(0.95 * total_value / sz_close) + self.buy(sz_data, size=lots) +``` + +Three design details worth stealing. First, the comparison uses `close/MA` ratios, not raw prices — momentum is normalized so two ETFs at different price scales become comparable. Second, "both below the MA → close everything" gives the strategy the right to *decline to play*; rotation strategies die when forced to pick a side in a downtrend. Third, sizing with `int(0.95 * total_value / price)` instead of a fixed lot lets the equity curve compound. Baseline (from 2011-09-20, 0.02% commission, 50,000 initial): 2,600 bars, 266 buys, 265 trades, 16.19% annualized, 32.03% max drawdown, final value 235,146.29. Handsome returns — and a one-third drawdown to remind you style rotation is never gentle. + +## Deep Dive 2: Treasury Calendar Spread — A Lesson in Ideal vs Reality + +The textbook calendar arbitrage reads like a physics problem: when the near/far spread exceeds carry cost, sell near, buy far, wait for convergence. [test_20_arbitrage_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/special/test_20_arbitrage_strategy.py) builds the full engineering version — including the hardest part, rollover: + +```python +# Open position +if self.market_position == 0: + # Open long + if near_data.close[0] - far_data.close[0] < self.p.spread_low: + self.buy(near_data, size=1) + self.sell(far_data, size=1) + self.market_position = 1 + self.holding_contract_name = [near_data, far_data] + # Open short + if near_data.close[0] - far_data.close[0] > self.p.spread_high: + self.sell(near_data, size=1) + self.buy(far_data, size=1) + self.market_position = -1 + self.holding_contract_name = [near_data, far_data] +``` + +The band `spread_low=0.06 / spread_high=0.52` defines the channel: break out to enter, revert to exit. The genuinely valuable engineering is `get_near_far_data()`: on every bar it ranks contracts by open interest to find the two most active, and once the dominant contract rolls, it closes old legs and re-opens them on the new pair in the original direction. A calendar-spread position *must* outlive the roll date — any arbitrage backtest without rollover logic is a toy. Then the honest part: 1,990 bars and 86 trades of T-contract data end at Sharpe **-2.24** and a final value of 918,003.89 from 1,000,000. These fixed thresholds lose money in-sample. Spreads do not revert unconditionally — and this asserted baseline teaches more than any profit curve. + +## The Rest of the Bench + +- **Convertible double-low** (`test_02`): registers bond value, conversion value, and premium rates as data lines; ranks price and premium cross-sectionally (`rank()`, not raw values — different scales demand ranks), blends 50/50 into a score, buys the top 20, rebalances on each month's last trading day. Baseline: 1,300 bars, 89 trades, Sharpe -2.97, max drawdown 4.03% — low drawdown, negative return: hiding in bond floors while missing the trend. +- **Premium-rate crossover** (`test_01`): the same extended fields on a single bond — 1,384 bars, 21 trades, final value 104,275.87. +- **Multi-source MA** (`test_04`): 30 bonds, each with its own 60-day MA — 4,434 bars, 460 trades, final value 14,535,803.03.

The price tag of naked breakouts on choppy instruments. +- **Hans123** (`test_14`): same data, a 200-MA direction filter on the opening-range breakout — 235 trades, final 958,610.35; less than a quarter of Fei's loss from the same 1M start.

That asymmetric buffer is the most practical small design in all ranked strategies. The rank itself arrives as a custom data line (`return_rank` via an extended `PandasData` feed), a clean pattern for shipping precomputed signals into backtrader. Eighteen years of gold: 4,324 bars, 20 trades, 12 wins against 7 losses (60% win rate, profit factor 3.50, final value 2,631,363.63 on 1,000,000) under futures-style commission — a low-frequency rhythm, plain to see. + +## Deep Dive 2: Safe Haven Rotation — When the Defensive Assets Hold a Tournament + +[test_0002_safe_haven_rotation.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/rotation/test_0002_safe_haven_rotation.py) asks a question most portfolios never formalize: *when risk-off actually arrives, which safe haven is strongest?* Five candidates — gold, silver, yen, franc, and a bond ETF as fallback. Note the neat trick for FX: USDJPY and USDCHF are inverted into yen- and franc-*strength* series, so all five assets point the same conceptual direction: + +```python +returns = {period: close_df / close_df.shift(period) - 1.0 for period in momentum_periods} +rank_scores = pd.DataFrame(0.0, index=close_df.index, columns=close_df.columns) +for period in momentum_periods: + period_rank = returns[period].rank(axis=1, ascending=False, method='min') + rank_scores = rank_scores.add(period_rank, fill_value=0.0) + +trend_ma = close_df.rolling(trend_ma_period).mean() +trend_ok = close_df > trend_ma + +# at month end: take the top-ranked asset that also confirms its trend +for asset in candidate_assets: + if bool(trend_ok.loc[dt, asset]): + chosen = asset + break +if chosen is None: + chosen = backup_asset # nobody confirms: retreat to the bond ETF +``` + +Blended 63/126-day momentum ranks pick the leader — but the crown only transfers if the leader also trades above its 63-day MA; otherwise capital falls back to bonds.

What separates it from a textbook pivot system is the four-way confirmation on the H1 timeframe: + +```python +if dif2 > 14 and self.adx[0] > 20 and self.plus_di[0] > self.plus_di[-1] and self.plus_di[0] > self.minus_di[0] and (self.ma_close[0] - self.ma_open[0]) >= ext_step and self.ma_close[-1] > self.ma_open[-1] and self.osma[0] > self.osma[-1]: +``` + +ADX above 20 (a trend exists), +DI rising and above -DI (direction is up), dual EMAs on close/open spreading for two bars (momentum confirms), OSMA histogram climbing (MACD pushes). The pivot answers "*where*"; four indicators jointly answer "*may I*." The baseline is sobering: 6,001 M15 bars produce 387 trades (200 wins, 187 losses) and a final value of 999,163.7 — a million in capital, three months of combat, 387 round trips, net standing still. No number states the cost-sensitivity of intraday breakout trading more plainly. + +## Deep Dive 2: Fibo iSAR — A Limit Order Waiting at the 50% Retrace + +[test_0004_fibo_isar.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/pivot_fibonacci_system/test_0004_fibo_isar.py) is the complete engineering specimen of Fibonacci trading. Direction comes from a dual-speed Parabolic SAR (fast 0.02/0.2, slow 0.01/0.1); entry waits at the 50% retracement of the swing, take profit sits at the 161.8% extension: + +```python +def _get_fibo(self, high, low, level): + return round(low + (high - low) * level, self.p.price_digits) + +... +op = self._get_fibo(max_price, min_price, self.p.fibo_entrance_level / 100.0) # 50.0 +tp = self._get_fibo(max_price, min_price, self.p.fibo_profit_level / 100.0) # 161.0 +sl = round(min_price - self.p.indent_stop_loss * self._trade_unit(), self.p.price_digits) + +if self.pending_buy is None and not self._has_position_side(True): + valid = bt.num2date(self.data0.datetime[0]) + pd.Timedelta(minutes=15 * self.p.order_valid_bars) + self.pending_buy = self.buy(size=self.p.size, exectype=bt.Order.Limit, price=op, valid=valid) +``` + +Three engineering details to steal. First, `exectype=bt.Order.Limit` *waits* for the pullback instead of chasing at market — a retracement strategy lives or dies on that one parameter. Second, `valid` gives the order a 45-minute lifetime (3 M15 bars): if price never pulls back, the order expires and levels are recomputed, so no stale "good price" lurks in the book. Third, the stop sits 30 trade-units beyond the swing extreme and then trails in 10/5 steps as profit accrues — entry, expiry, and trailing each have an explicit clock and ruler. Baseline: 6,128 bars, 335 trades, 194 wins / 141 losses, final value 1,005,690.9 — one of the few on the profitable side of this category. + +## The Rest of the Bench + +- **SimplePivot** (`test_0002`): the fruit knife to the first two strategies' heavy machinery. Pivot is just the midpoint of yesterday's high/low; direction is wherever the open lands — below yesterday's high but above the midpoint means short, otherwise long — always in the market, flipping via `notify_order`'s close-first-then-reopen choreography. ~3 months of daily data (resampled from M15), 25 trades, 15 wins / 10 losses. +- **PivotHeiken 3** (`test_0003`): LWMA double-smoothed Heikin-Ashi momentum as a mean-reversion trigger below the daily pivot — 6,038 bars, a category-high 1,584 trades. +- **FiboCandles** (`test_0005`): multiplies the range by fibo ratios (0.236/0.382/0.5/0.618/0.762, five selectable) as color-flip thresholds — 6,093 bars, 95 trades, 56 wins / 39 losses. +- **Volatility Pivot** (`test_0006`): the pivot becomes a moving flip line that breathes with ATR(100)×3 — 4,446 bars, just 9 trades. The most patient of the six. + +## Run It Yourself + +```bash +# The whole category (6 strategies) +pytest tests/functional/strategies/pivot_fibonacci_system/ -v + +# Just Fibo iSAR +pytest tests/functional/strategies/pivot_fibonacci_system/test_0004_fibo_isar.py -v +``` + +## Why Study Pivots and Fibonacci Here + +All six strategies run on M15 data with multi-timeframe feeds, limit orders, order lifetimes, and bar-by-bar trailing stops — each feature is a stress test of the engine's event-driven path, and being one bar off anywhere rewrites MostasHaR15's 387-trade win/loss distribution. [cloudQuant/backtrader](https://github.com/cloudQuant/backtrader) pins every count, win/loss tally, and final value into asserted baselines across 1,152 strategy regression tests, with runonce/runnext dual-mode parity ensuring both engine paths emit the identical trade list.

The classic tragedy: perfect signal, precise entry — then lunch runs long and nobody placed the stop. + +This article covers the 6 order-type backtests in `tests/functional/strategies/order_types/`. They are not six "strategy ideas" but six interface contracts between your strategy and the market — how the bracket trio makes "every entry carries a stop" an atomic operation, how OCO makes a group of orders mutually exclusive. Consider this the "framework feature + strategy" episode of the series: a working tour of backtrader's order API. + +## Category at a Glance + +| Strategy | Data | Core idea | Source | +|----------|------|-----------|--------| +| Stop order | Convertible-bond index, daily | After a golden-cross fill, auto-place a 3% stop; exit on dead cross | `test_05_stop_order_strategy.py` | +| Bracket trio | 2005-2006 daily | Limit main + stop + target submitted as one package; child orders arm on parent fill | `test_37_bracket_order_strategy.py` | +| OCO orders | 2005-2006 daily | Three limit buys at different depths; one fill cancels the rest | `test_41_oco_order_strategy.py` | +| StopTrail | 2005-2006 daily | MA-cross entry template with a `trailpercent` parameter on standby | `test_42_stoptrail_strategy.py` | +| Order Target | YHOO 2005-2006 daily | Compute target position percent by date; `order_target_percent` does the diff | `test_43_order_target_strategy.py` | +| Order Close | 2005-2006 daily | `exectype=bt.Order.Close` fills at the current bar's close | `test_61_order_close.py` | + +## Deep Dive 1: Bracket — Making the Stop an Atomic Operation + +In a backtest, "forgot the stop" never happens — code always remembers. The bracket order's value is sinking that memory into the **order structure itself**: main order, stop-loss, and take-profit submitted as one unit; the moment the main order fills, both children arm; when either child fills, the other is cancelled. The human loophole is closed by the order book. + +The implementation ([test_37_bracket_order_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/order_types/test_37_bracket_order_strategy.py)) builds the trio in one shot on a golden cross: + +```python +if self.cross > 0.0: + close = self.data.close[0] + p1 = close * (1.0 - self.p.limit) # main: limit buy 0.5% below + p2 = p1 - 0.02 * close # stop: 2% of close below p1 + p3 = p1 + 0.02 * close # target: 2% of close above p1 + + o1 = self.buy(exectype=bt.Order.Limit, price=p1, + valid=valid1, transmit=False) + o2 = self.sell(exectype=bt.Order.Stop, price=p2, + valid=valid2, parent=o1, transmit=False) + o3 = self.sell(exectype=bt.Order.Limit, price=p3, + valid=valid3, parent=o1, transmit=True) # last order ships the group +``` + +The keys are `transmit` and `parent`: the first two orders are held back with `transmit=False` until the third one's `transmit=True` releases the whole group; `parent=o1` declares the hierarchy the engine uses to arm children on fill and cancel the sibling when one side executes. On 2005-2006 data this yields 8 completed round trips (4 wins, 4 losses — a clean 50%), final value 99,875.56, pinned by `abs(final_value - 99875.56) < 0.01`. Note the main order is a limit valid for 3 days: if price never pulls back, the whole package expires — in a bull run you miss the move. That's the bracket's price of discipline. + +## Deep Dive 2: OCO — One Group of Orders, Only One Future + +OCO (One-Cancels-Other) solves the opposite problem: **you want to buy the dip, but you don't know how deep the dip runs.** Instead of guessing one price, place a limit order at each of three depths and declare them mutually exclusive — first to fill cancels the rest. + +[test_41_oco_order_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/order_types/test_41_oco_order_strategy.py) hangs three buys on a golden cross, depths growing with the square and cube of the offset: + +```python +p1 = self.data.close[0] * (1.0 - self.p.limit) # 0.5% below +p2 = self.data.close[0] * (1.0 - 2 * 2 * self.p.limit) # 2% below +p3 = self.data.close[0] * (1.0 - 3 * 3 * self.p.limit) # 4.5% below + +o1 = self.buy(exectype=bt.Order.Limit, price=p1, valid=valid1, size=1) +o2 = self.buy(exectype=bt.Order.Limit, price=p2, valid=valid2, oco=o1, size=1) +o3 = self.buy(exectype=bt.Order.Limit, price=p3, valid=valid3, oco=o1, size=1) +``` + +`oco=o1` links the later orders into the first one's group. The near order gets only 3 days of validity (`limdays=3`), the far ones get 1,000 — betting that shallow pullbacks come fast while deep ones are worth waiting for. After a fill, the position is held 10 bars and closed by time. The backtest ends at 99,936.20 with a Sharpe of **-728** — an extreme value that is not a bug but the arithmetic of 1-share positions with sparse trades under tiny annualized volatility. The test's own comment says it plainly: these numbers confirm the **OCO cancellation mechanism works**, not that the strategy profits. That is a regression test doing its actual job — validating framework behavior, not returns. + +## The Rest of the Bench + +- **Stop order** (`test_05`): on the convertible-bond index, the fill triggers `self.sell(exectype=bt.Order.Stop, price=buy_price * 0.97)` inside `notify_order`; a dead cross cancels the stop before the market close — cancel-then-close ordering is the classic detail of managing resting orders. 211 buys over the run, 106 stopped out. +- **StopTrail** (`test_42`): descended from the official stoptrail sample, params keep `trailpercent=0.02`; this version runs on cross-driven market orders (final 105,190.30, Sharpe 1.19). Rewriting it as a true `sell(exectype=bt.Order.StopTrail, trailpercent=0.02)` is the best exercise on this page. +- **Order Target** (`test_43`): declare targets, not trades — odd months hold `date/100` percent, even months `(31-date)/100`, and `order_target_percent` computes and places the difference. The on-ramp from "trade thinking" to "position thinking." +- **Order Close** (`test_61`): `exectype=bt.Order.Close` fills at the current bar's close (paired with `seteosbar(True)`), removing the one-bar next-open delay; final value 102,995.50. + +## Run It Yourself + +```bash +# The whole category (6 strategies, runonce/runnext dual-mode parity) +pytest tests/functional/strategies/order_types/ -v + +# Just the bracket trio +pytest tests/functional/strategies/order_types/test_37_bracket_order_strategy.py -v +``` + +## Why Study Order Types Here + +Order semantics are where backtest fidelity quietly dies: whether a limit fills on a touch, the gap between a stop's trigger and its fill price, the exact timing of OCO cancellations — all depend on broker-simulator precision.

Expiration week therefore behaves differently in volatility, volume, and price — prime hunting ground for calendar strategies.

Around that week, hedging flows (gamma hedging, rolling) are believed to suppress or push the spot price. This strategy does not try to predict *where* pinning happens — it bets on a coarser claim: **certain months exhibit systematic drift during expiration week**. + +[test_0002_options_expiration_week.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/options/test_0002_options_expiration_week.py) first locates the expiration week with a calendar algorithm, assigns each month a bull/bear bias, then enters Monday and exits Friday: + +```python +def _third_friday(year, month): + month_calendar = calendar.monthcalendar(year, month) + friday_count = 0 + for week in month_calendar: + if week[calendar.FRIDAY] != 0: + friday_count += 1 + if friday_count == 3: + return week[calendar.FRIDAY] # third Friday of the month + +monday_day = third_friday - 4 # Monday = Friday minus 4 days +in_week = monday_day <= idx.day <= third_friday and idx.weekday() <= 4 +bias = 1.0 if idx.month in bullish_months else (-1.0 if idx.month in bearish_months else 0.0) +entry_signal.append(1.0 if in_week and idx.weekday() == 0 and bias != 0.0 else 0.0) +exit_signal.append(1.0 if in_week and idx.weekday() == 4 else 0.0) +``` + +Parameters declare months 1-5 and 9-12 bullish, 6-8 bearish, with 95% position size, a 2% stop-loss, and a 1.5% take-profit. The honest verdict is written into the assertions: on GLD 2008-2025 — 4,519 bars, 199 trades, 49.2% win rate, final value 947,033.84, a **5.3% loss**, Sharpe -0.02, max drawdown 32.89%. Hard-coded monthly biases do not even survive in-sample — a textbook example of the most common trap in seasonality research. + +The engineering is worth studying: **features and strategy are layered**. Expiration-week flags, monthly bias, and entry/exit signals are all computed offline in pandas and attached as extra columns on a custom `PandasData` feed; `next()` reads just three lines (`entry_signal`, `exit_signal`, `direction`). Calendar logic and trading logic are fully decoupled — change one without touching the other, and the engine never needs to understand calendars. + +## Deep Dive 2: GLD Put Write — What Premium Sellers Actually Earn + +A cash-secured put write is the strategy of "I am willing to buy at this price, and you pay me a deposit first." The payoff is inherently twisted: **high probability of small wins (premium), small probability of large losses (catching a falling knife)** — high win rate, poisonous tail. + +[test_0005_gld_put_write_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/options/test_0005_gld_put_write_strategy.py) prices the option with an approximation that skips full Black-Scholes: + +```python +def _estimate_option_mark(self, spot, strike, days_to_expiry, realized_vol): + vol = max(float(realized_vol or 0.0), 0.05) + time_value = vol * math.sqrt(max(days_to_expiry, 1) / 365.0) * float(spot) * float(self.p.premium_factor) + intrinsic = max(0.0, float(strike) - float(spot)) + return intrinsic + time_value + +def _round_strike(self, price): + strike = price * float(self.p.moneyness) # 0.95 → 5% out-of-the-money + return round(strike / 0.5) * 0.5 # rounded to $0.50 +``` + +The entry filter requires price above the 200-day average **and** RSI at or above 30 — no knife-catching mid-crash. While holding, the mark is re-priced daily at the new volatility; if the premium doubles (a 50% rise, the stop line), the put is bought back; otherwise it is held to the 30-day expiry. This open—mark-to-market—stop-or-expire loop is precisely the daily rhythm of a real option seller. + +The backtest (2010-2025): 92 opens, 82 natural expiries, 9 stops, **win rate 81/91 ≈ 89%**, final value 1,156,219.97 (+15.6%). But remember what the 9 stops represent — the tail risk made visible. In a 2008-style market that number grows exponentially. Split the win rate from the payoff ratio: the flip side of 89% wins is how much those 9 stops must average to drag expectancy back to zero. The "comfort" of a put write is exactly where its danger lives. + +## The Rest of the Bench + +- **Expiration week, XAUUSD version** (`test_0001`): the same idea on spot gold, long-only in months 3/4/10/12 with October and December weighted 1.2x — month-weighting is one of the less arbitrary variants in calendar trading. +- **Low-volatility options combo** (`test_0003`): 0.5 parts JEPI + 0.25 parts PBP + 0.25 parts synthetic put-write, rebalanced every 63 days, 12% volatility target, risk halved when drawdown exceeds 20% — an institutional-style "options income all-weather" portfolio. +- **Options valuation** (`test_0004`): does not trade options at all — it treats "volatility is cheap/expensive" as a timing signal, going long when the 252-day percentile of realized volatility falls below 0.2 and exiting above 0.8. + +## Run It Yourself + +```bash +# The whole category (5 strategies) +pytest tests/functional/strategies/options/ -v + +# Just the GLD put write +pytest tests/functional/strategies/options/test_0005_gld_put_write_strategy.py -v +``` + +## Why Study Options Here + +Approximate option modeling is terrified of "the engine's numbers quietly changed": tiny drift in the `sqrt(days/365)` pricing term or the daily mark-to-market cash flows distorts every win-rate statistic.

[test_51_optimization.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/advanced/test_51_optimization.py) compresses the standard workflow into three moves: + +```python +cerebro.optstrategy( + OptimizeStrategy, + smaperiod=range(10, 13), # 3 values: 10, 11, 12 + macdperiod1=[12], macdperiod2=[26], macdperiod3=[9], +) +... +best_result = max(all_results, key=lambda x: x['sharpe_ratio'] or -999) +best_params = {'smaperiod': best_result['smaperiod']} +best_metrics = run_best_strategy(best_params, runonce=runonce) # full rerun with the winner +``` + +**Sweep → select by Sharpe → rerun and verify.** The assertions lock the outcome down: of the 3 parameter sets the best is `smaperiod=10`; the rerun covers 221 bars and 10 trades, ending at 100,150.06 with Sharpe 0.4979. Note the plumbing detail: optimization results arrive as a nested list (`for stratrun in results: for strat in stratrun`) — one strategy instance per parameter set, each with its own analyzers. The framework does the grouped-collection dirty work for you. + +But this 3-cell grid is itself an overfitting lesson. Picking parameters on a single year (2006) means any "best" is likely noise; the serious approach is in-sample/out-of-sample splitting — tune on the first half, validate on the second, and if out-of-sample performance collapses, you optimized a historical coincidence, not a pattern. A subtler trap is **the selection metric itself**: choosing by Sharpe favors low-volatility, low-trade combinations that may rest on one or two lucky trades; switching to Calmar or adding a minimum-trade constraint often crowns a completely different "best." Also note `bt.Cerebro(maxcpus=1)`: single-threaded for reproducibility — in production, unleash the cores. + +## Deep Dive 2: Signal Strategies — Trading Without a Strategy Class + +The same "go long when price stands above its average" can be declared as a signal line handed to the framework — no `next()`, no order management ([test_44_signals_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/advanced/test_44_signals_strategy.py)): + +```python +cerebro.add_signal(bt.SIGNAL_LONG, bt.indicators.SMACloseSignal, period=30) +``` + +That is the entire strategy — one line. `SMACloseSignal` outputs `price - SMA(30)`: positive opens a long, negative closes it, and **position size is proportional to the signal value** — the further price runs from the average, the larger the position. Four signal types exist (`SIGNAL_LONG`, `SIGNAL_SHORT`, `SIGNAL_LONGSHORT`, `SIGNAL_LONGEXIT`), and multiple lines can be stacked so entry uses signal A while exit uses signal B — more powerful than it looks. + +The cost is in the numbers: 21 trades, final value 50,607.58, Sharpe -12.58, max drawdown 64%. "Size scales linearly with distance" means the position is heaviest at trend tops. Declarative signals are perfect for quickly validating indicator combinations; complex risk logic still belongs in a Strategy class. Two dialects, one engine — use each where it fits. + +## The Rest of the Bench + +- **Multiple trades** (`test_45`): with `mtrade=True`, each new entry rotates the trade id (0→1→2) so several trades book P&L and close independently inside one strategy — the underlying machinery for pyramiding and scaled exits. +- **Strategy selection** (`test_48`): `StrategyA` (dual-MA crossover) and `StrategyB` (price vs single MA) share one interface and are injected at runtime — turning the *strategy itself* into a configurable parameter. +- **Multi-data** (`test_59`): `bt.ind.SMA(self.data1, period=15)` computes the signal on data 1 while orders execute on data 0 (0.5% commission); backtrader aligns the two streams by timestamp automatically — the generic skeleton for lead-lag and pairs trading. + +## Run It Yourself + +```bash +# The whole category (5 strategies, runonce/runnext parity asserted automatically) +pytest tests/functional/strategies/advanced/ -v + +# Just the optimizer +pytest tests/functional/strategies/advanced/test_51_optimization.py -v +``` + +Every test runs twice — vectorized (`runonce=True`) and event-driven (`runonce=False`) — and asserts identical metrics, so engine regressions get caught immediately. + +## Why Study the Framework Here + +Parameter optimization is a bottomless pit of compute: a 3-cell grid is trivial, a 300-cell grid is another story. [cloudQuant/backtrader](https://github.com/cloudQuant/backtrader)'s pure-Python engine is 46% faster than the original, and the C++ backend (`pip install back-trader-cpp`) adds a median 128x speedup — turning sweeps from overnight jobs into coffee breaks. The 1,152 strategy regression tests and runonce/runnext dual-mode parity guarantee the speed was not bought with matching-semantics drift: you are optimizing your parameters, not chasing engine bugs. Asserted metric baselines make every grid rerun precisely comparable to the last. + +Find it useful? Star the project on [GitHub](https://github.com/cloudQuant/backtrader).

Everyone can recite Buffett's maxim — but how do you *quantify* fear?

The Fear & Greed index is a composite of seven sub-indicators (momentum, breadth, volatility...) — a *state* measure; PCR records which way option buyers are betting right now — a *behavior* measure; VIX is the implied quote for 30-day volatility — an *expectation* measure. Sentiment strategies use these **slow variables** as timing filters — extreme readings appear only a few times a year, so the strategies trade only a few times a year.

The engineering lesson is the data plumbing: sentiment indicators are not OHLC bars, so the test extends `GenericCSVData` and mounts Put/Call, F&G, and VIX as three extra lines on the price stream: + +```python +class SPYFearGreedData(bt.feeds.GenericCSVData): + lines = ('put_call', 'fear_greed', 'vix') + params = (('dtformat', '%Y-%m-%d'), ('datetime', 0), ('open', 1), ('high', 2), + ('low', 3), ('close', 4), ('volume', 6), ('openinterest', -1), + ('put_call', 7), ('fear_greed', 8), ('vix', 9)) +``` + +The backtest (SPY, 2011-2021): 2,445 daily bars, only **6 buys and 2 sells**, both closed trades winners, final value 280,859.60 (11.2% annualized, Sharpe 0.89), max drawdown 24.3%. Note the last buy never closes — if greed is late to arrive, the position stays exposed to the market, and that 24.3% drawdown is the price of waiting. Six buys in 11 years also exposes the statistical embarrassment of this family: a 100% win rate on two closed trades proves nothing. 2011-2021 was a historic US bull run — "extreme fear always rebounds" may be a property of bull markets, not of sentiment. Run the same 10/94 thresholds over 2000-2010 and the answer may differ entirely. + +## Deep Dive 2: Put/Call Ratio — the Options Market's Ballot + +PCR = put volume / call volume. A spiking ratio means everyone is buying insurance; a bottoming ratio means everyone is chasing calls naked. [test_23_put_call_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/sentiment/test_23_put_call_strategy.py) keeps the same skeleton and swaps the signal line: `PCR > 1.0` reads as peak fear — buy; `PCR < 0.45` reads as euphoria — liquidate. On the same SPY data: 6 buys, 3 sells, all 3 closed trades winners, final value 240,069.35 (Sharpe 0.83). + +The comparison with Fear & Greed is instructive: the two indicators are highly correlated (both fear-derived), the entry counts are identical (6), yet different exit timing produces a 40,000-dollar gap in final value — **the alpha of sentiment strategies hides in the exit rules**. The other implication of slow variables is tiny samples: 3-6 trades in 11 years cannot pass any significance test. A backtest can prove the logic *runs*; it cannot prove the pattern *exists*. + +## The Rest of the Bench + +- **VIX** (`test_24`): the bluntest version — buy above 35, exit below 10. In 11 years it triggers only 3 buys (readings above 35 are rare), ending at 261,273.50 with Sharpe 0.92 — the laziest and sharpest of the trio. VIX above 35 happens almost exclusively mid-crash: this is knife-catching, with the worst drawdown of the three (33.7%) and the fattest returns. +- **BTC Google Trends** (`test_33`): retail sentiment, crypto edition — Bollinger bands (period 10, devfactor 1) on Google Trends search heat; a break above the upper band goes long, below the lower band goes short, return to the midline flattens. Engineering-wise it demonstrates dual feeds: BTC price is `datas[0]`, search heat rides in as `datas[1]`'s close, and the indicator sits directly on the sentiment line. On weekly bars: 16 buys, 16 sells, roughly 50/50 (final value 15,301.43 from 10,000) — far higher turnover than the SPY trio. Crypto sentiment is a fast variable, and here it is used *with* the trend — the exact opposite of the contrarian SPY family. + +## Run It Yourself + +```bash +# The whole category (4 strategies, runonce/runnext parity asserted automatically) +pytest tests/functional/strategies/sentiment/ -v + +# Just Fear & Greed +pytest tests/functional/strategies/sentiment/test_22_fear_greed_strategy.py -v +``` + +Every test runs twice — vectorized (`runonce=True`) and event-driven (`runonce=False`) — and asserts identical metrics, so engine regressions get caught immediately. + +## Why Study Sentiment Here + +Sentiment strategies trade sparsely and are path-sensitive — a single fill at a different price reshapes the whole equity curve, which makes matching fidelity and reproducibility in the backtest engine critical.

The pure-Python engine is 46% faster than the original and the C++ backend (`pip install back-trader-cpp`) adds a median 128x speedup — so scanning alternative thresholds (what if 10/94 became 15/90?) takes minutes, not weekends. + +Find it useful?

The 2008 crisis tore up the menu: panic sent the yen soaring, carry positions worldwide unwound simultaneously, and AUD/JPY collapsed within months — the rent-collectors gave back years of rent in weeks. **Carry is not a free lunch; it is a premium for bearing tail risk** — academia gave it a blunt name: carry crash. + +Why does the spread exist at all? One explanation: it is compensation for depreciation risk. High-yield currencies usually pay high rates because inflation is high and the central bank is tight — and over the long run their exchange rates tend to weaken, while low-yield safe-haven currencies appreciate in crises.

The 2008-2025 backtest — 4,549 bars, 217 rebalances, 200 trades — delivers a brutally honest result: final value 912,208.05 (**-8.8%**), Sharpe -0.27, win rate 41%. The proxy did not reproduce the interest-rate spread — the trend term hijacked the signal. That is itself the engineering lesson: **bias introduced by a proxy variable can quietly turn a factor strategy into a different strategy.** + +## Deep Dive 2: Gold-Rate Carry — Turning Carry into a Cointegration Pair + +The other route skips rankings and builds a pair.

Exits trigger when the residual converges inside ±0.2, with a hard 3x ATR stop as backstop (25% position, shorts allowed). The dual z-score design is one notch more rigorous than "trade when the spread moves": it requires both the driver (rates) and the driven (gold) to flash extreme readings, filtering out reams of one-sided noise. + +The result: 4,258 bars, 117 trades, a 41% win rate carried by the payoff ratio to a profit factor of 1.13, final value 1,032,287.54 (+3.2%).

Forecasting markets — especially forecasting prices — has a worse reputation still.

Split the problem: predicting tomorrow's *magnitude* (up 0.83% or 1.2%?) is nearly impossible; predicting *direction* (green candle or red?) runs slightly better than a coin flip in trending markets — and a directional position only needs direction. Combine that with exits that cut losses and let winners run, and a 55% directional hit rate can compound into positive expectancy. All three strategies in `tests/functional/strategies/forecasting/` take this path: ARIMA describes "how much tomorrow's return remembers today" in autoregressive language; the forecast oscillator measures "how far price sits from its regression-forecast line."

Choosing ARIMA(1,0,1) over something grander is itself a position: the dependency structure worth modeling in daily returns is shallow — a little memory of yesterday's return, a little of yesterday's shock, and beyond that you are fitting historical noise. The classic stylized facts agree: return autocorrelation is weak; the strong structure is volatility clustering, and that is GARCH territory, not ARIMA's. + +[test_0001_arima_time_series_forecast.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/forecasting/test_0001_arima_time_series_forecast.py) rolls the forecast over daily returns: + +```python +for idx in range(train_window, len(out)): + if fitted_model is None or (idx - train_window) % refit_interval == 0: + train_series = returns.iloc[idx - train_window:idx].reset_index(drop=True) + fitted_model = ARIMA(train_series, order=selected_order).fit() # (1, 0, 1) + forecast = fitted_model.forecast(steps=1) + forecasts[idx] = float(forecast.iloc[0]) + +out["signal"] = np.where(np.nan_to_num(out["forecast_return"], nan=0.0) > forecast_threshold, 1.0, 0.0) +out["target_pct"] = out["signal"] * target_percent # positive → 95% long, else flat +``` + +Three parameters deserve a chew: a 252-day training window (one year), **a refit every 20 days**, and a zero forecast threshold — positive forecast means long, negative means flat, never short. Fixed-interval refitting is walk-forward in its cheapest form: the model only ever sees the past, absorbs new information every 20 days, and lookahead bias never gets a chance. It also explains the architecture — features are precomputed in pandas, and `next()` merely rebalances toward `target_pct`. Model fitting and order execution live in two worlds separated by a signal table. + +The backtest (gold 2022-2025, a futures-style contract with 100x multiplier): across 1,032 daily bars the strategy signals long on 740 days and flat on 292 — yet only 6 rebalances and 2 completed trades (2 wins, 0 losses), ending at 2,151,710.03. Two cautions. First, leverage flatters the optics: at 1% margin and a 100x multiplier, a 95% target position means enormous notional exposure. Second, a sample of 2 closed trades says the **forecast signal is a slow variable** — with only 5 sign switches in four years, ARIMA is catching months-scale drift in gold, not daily fluctuation. Direction can indeed be guessed — but it rides trend inertia, not a crystal ball. + +## The Rest of the Bench + +- **Forecast oscillator** (`test_0002`): a port of the MT4/MT5 Forecast Oscillator — the percentage deviation of price from its linear-regression forecast, smoothed with Tillson T3 and traded on line crossovers at the 12-hour timeframe. 21 trades over 111 bars, 52.4% win rate, final value 999,479.5 — high-frequency break-even, a textbook for the commission-sensitive. +- **EMA prediction** (`test_0003`): a dual-timeframe structure — fast/slow EMAs (periods 1 and 2, so aggressive they nearly track price) cross on H6 to set direction, M15 executes, with a 1,000-point stop and 2,000-point target. 55 trades, 40% win rate, final value 1,000,475.90, Sharpe 0.80 — another exhibit for "win rate is not the point." + +Taken together, the category's practical lesson is clear: **forecasting in production means producing an executable directional call today, then letting exit rules stitch a small edge into positive expectancy.** Improving model accuracy by a point is brutal; improving stop discipline pays immediately — study forecasting, and you end up studying position management. + +## Run It Yourself + +```bash +# The whole category (3 strategies) +pytest tests/functional/strategies/forecasting/ -v + +# Just the ARIMA walk-forward +pytest tests/functional/strategies/forecasting/test_0001_arima_time_series_forecast.py -v +``` + +## Why Study Forecasting Here + +Rolling refits plus bar-by-bar replay make walk-forward backtests several times more expensive than ordinary strategies — a model fit hides behind every bar. [cloudQuant/backtrader](https://github.com/cloudQuant/backtrader)'s pure-Python engine is 46% faster than the original and the C++ backend (`pip install back-trader-cpp`) adds a median 128x speedup, so compressing the refit interval from 20 days to 5 becomes an experiment you can run over coffee. The 1,152 strategy regression tests with asserted metric baselines and runonce/runnext dual-mode parity keep every number in the pipeline reproducible and comparable — before you research forecasting, you must be able to forecast your own backtest results. + +Find it useful?

+[test_0002_gold_hmm_trend_following.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/trend_following/test_0002_gold_hmm_trend_following.py) 是全篇最手写的测试（431 行，非模板生成），也是"状态机"思想的完整落地。它对黄金日线（2024-01-01 至 2025-12-31）做三件事： + +**第一，滚动拟合。** 用 252 个交易日窗口、每 21 天重训一次 `GaussianHMM(n_components=3, covariance_type="full")`，特征只有两个——对数收益与 20 日年化波动率。模型输出 3 个隐藏状态后，按训练集上的平均收益**贴标签**：均值最高的是 BULL，最低的是 BEAR，剩下的是 NEUTRAL。 + +**第二，三重置信度门。** 光有状态不够，还要确信： + +```python +vol_factor = min(target_volatility / max(float(current_row["volatility_20"].iloc[0]), 1e-6), + max_target_percent / max(base_target_percent, 1e-6)) +dynamic_target = min(max_target_percent, base_target_percent * current_confidence * vol_factor) +if current_confidence < state_persistence_min or persistence < state_persistence_min or consistent < 0.5: + dynamic_target = 0.0 +``` + +仓位 = min(0.10, 0.03 × 状态置信度 × 波动率目标因子)；而"状态后验概率、转移矩阵对角线（状态黏性）、连续 3 日同状态"三个置信度任一低于 0.7，目标仓位直接归零——宁可错过，不可误判。 + +**第三，保本武装。** 浮盈一旦达到 8%，止损线从 −3% 上移到 0；此外还有状态反转平仓与 NEUTRAL 状态减半仓。**回测结果**：两年 245 根日线只做 6 笔（3 胜 3 负），终值 1,000,059.99——含 0.02% 佣金后约打平。工程上两处值得学：`pytest.importorskip("hmmlearn")` 让可选依赖缺席时整模块优雅跳过；HMM 特征在 pandas 里预计算、经自定义 `PandasData` 行注入策略，回测引擎保持纯净。 + +## 深读二：FATL/SATL——把趋势线做成数字滤波器 + +均线是"滤波器"的粗糙形态，俄罗斯技术分析学派干脆按频域设计指标：FATL（Fast Adaptive Trend Line）是 39 项固定系数的 FIR 低通滤波器，SATL（Slow）是 65 项——系数直接写死在数组里（FATL 首项 0.4360409450，SATL 首项 0.0982862174），无任何参数可调。[test_0258_1048_fatl_satl_osma.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/trend_following/test_0258_1048_fatl_satl_osma.py) 在 H12 周期上计算两者之差构成 OsMA 振荡器，拐头即入场： + +```python +def compute_fatl_satl_osma(frame, point=0.01): + price = frame['close'].to_numpy(dtype=float) + values = np.full(len(frame), np.nan, dtype=float) + min_rates_total = int(max(len(FATL_COEFFS), len(SATL_COEFFS))) + for idx in range(min_rates_total - 1, len(frame)): + fatl = float(np.dot(FATL_COEFFS, price[idx - np.arange(len(FATL_COEFFS))])) + satl = float(np.dot(SATL_COEFFS, price[idx - np.arange(len(SATL_COEFFS))])) + values[idx] = (fatl - satl) / point # 快慢趋势的背离程度 + out = frame.copy() + out['fatl_satl_osma'] = values + return out.dropna(subset=['fatl_satl_osma']) +``` + +FIR 卷积被一行 `np.dot` 向量化——指标即数据。**回测结果**同样诚实：16 笔交易只赢 3 笔，终值 992,663.99。滤波器把噪声滤掉了，也把这段行情的趋势滤掉了；65 根 H12 的暖机窗口就要吃掉样本的一大半。它留在测试库里的价值不是收益，而是"零参数指标"这个流派的完整参照。 +

ETF IEF——对齐到 2008-2025 的共同交易日历，每月末做两件事：按 252 日波动率的倒数分配等风险权重，然后用 200 日均线做闸门，价格在下方的资产权重归零、转为现金： + +```python +if bool(month_end.loc[dt]): + vol_row = rolling_vol.loc[dt].dropna() + if len(vol_row) > 0:

float(trend_signal.loc[dt, asset]) if asset in trend_signal.columns else 0.0 + active_weights[asset] = base_weight * signal # 趋势闸门 + total_active = float(sum(active_weights.values())) + current_weights.update(active_weights) + current_cash = max(0.0, 1.0 - total_active) # 熊市权重让给现金 +``` + +细节见功力：`invert_price_frame` 把 USDJPY 取倒数变成"日元强度"序列时，high/low 必须互换——倒数会反转高低顺序，这种坑只有真做过的人知道。**回测结果**：18 年、4,287 根日线、206 次再平衡、89 笔交易只赢 23 笔（胜率约 26%），终值 1,235,742.09（+23.6%，佣金 0.1%）。又一次，低胜率与正收益并存——趋势闸门把熊市的仓位让给现金，剩下的小亏是门票，少数大波段是奖品。 + +## 其余策略，快速点将 + +-

的规则可以浓缩成一句话：**长期趋势向上时，短期超卖就是买点**。仓库实现（[test_0004_rsi2_mean_reversion.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/mean_reversion/test_0004_rsi2_mean_reversion.py)）在 XAUUSD 日线上跑了 2008 到 2025 共 17 年： + +```python +params = dict( + rsi_period=2, # 极短周期：只捕捉两根 K 线内的衰竭 + rsi_buy_threshold=5, # 阈值不是 30，是 5——极度超卖 + rsi_sell_threshold=30, # RSI 修复到 30 即离场，不贪 + sma_period=100, # 趋势过滤：只在 100 日均线上方做多 +) + +# Entry: RSI 低于买阈值，且收盘价仍在 SMA 上方（趋势内超卖） +out['buy_signal'] = ((out['rsi'] < rsi_buy) & + (out['close'] > out['sma'])).astype(float) +# Exit: RSI 回升穿越卖阈值 +out['sell_signal'] = (out['rsi'] > rsi_sell).astype(float) +``` + +两个设计值得咀嚼。其一，`rsi_period=2` 让 RSI 变得极其敏感——两天连跌就能把它打到 5 以下，这正是 Connors 想要的"恐慌计"。其二，`sma_period=100` 是安全带：2008、2013、2021 这类单边崩跌里 RSI(2) 天天贴地，但只要价格在均线下方，信号一个都不会触发。 + +回测数字（断言钉死的基线）：4,538 根日线、311 笔交易、胜率 67.85%，终值从 100 万做到 1,703,436.24（+70.34%），最大回撤 17.37%，SQN 2.06。这不是暴利策略，但作为一个只有四个参数的规则系统，17 年翻 1.7 倍、三分之二交易赚钱——这就是它被封为短线均值回归教科书的原因。 + +## 深读二：ConnorsRSI——把三个维度揉成一个振荡器 + +Connors 后来的进化版 ConnorsRSI（[test_0020_connorsrsi_mean_reversion.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/mean_reversion/test_0020_connorsrsi_mean_reversion.py)）不再只看价格动量，而是把三个互补的维度平均成一个复合分数： + +```python +price_rsi = _calculate_rsi(close, 3) # 价格动量 RSI(3) +streak_rsi = _calculate_rsi(_calculate_streaks(close), 2) # 连胜/连败天数序列的 RSI(2) +percent_rank = _calculate_percent_rank(close, 100) # 当前价在 100 日内的百分位 +out['crsi'] = pd.concat([price_rsi, streak_rsi, percent_rank], axis=1).mean(axis=1) + +# 入场：CRSI 深度超卖 + 距 26 周高点不远（趋势没坏）+ 价在 200 日均线上方 +out['setup_signal'] = ( + (out['crsi'] < float(params.get('crsi_entry', 20.0))) + & (out['days_since_high'] <= float(params.get('recent_high_max_days', 30))) + & (out['close'] > out['trend_ma']) +).astype(float) +``` + +`streak_rsi` 是点睛之笔：先数出"连续上涨/下跌天数"序列，再对这个序列算 RSI——它衡量的是**连胜连败本身的衰竭程度**，和价格 RSI 相互印证。入场端还多了一层工程味道：不是市价追入，而是挂**低于昨收 0.3% 的限价单、次日作废**： + +```python +limit_price = float(self.data.close[-1]) * (1.0 - float(self.p.entry_discount_pct) / 100.0) +valid_until = current_dt + timedelta(days=1) +self.order = self.buy(size=..., exectype=bt.Order.Limit, price=limit_price, valid=valid_until) +``` + +结果：17 年只有 38 笔成交（52 次信号中 14 张限价单过期作废——等不到更便宜就放弃），胜率 78.95%，盈利因子 3.38，最大回撤仅 6.42%。信号更挑剔、入场更便宜、回撤更浅，这是"少即是多"的量化样本。 + +## 深读三：Cronex RSI——给 RSI 做两次平滑 + +如果说 Connors 的方向是把 RSI 变得更"快"，Cronex

SMA(14) 平滑一次得到快线 `ind`，对 `ind` 再做 SMA(25) 平滑得到慢线 `sign`： + +```python +rsi = compute_rsi(price, rsi_period) # RSI(25)，Wilder 平滑 +ind = smooth_series(rsi, fast_period, xma_method) # SMA(14) → 快线 +sign = smooth_series(ind, slow_period, xma_method) # SMA(25) → 慢线（对快线再平滑） + +# 快线上穿慢线做多，下穿做空（信号在 H4 上评估，M15 执行） +if ind_curr > sign_curr and ind_prev <= sign_prev: + buy_open = True +``` + +双重平滑牺牲灵敏度换来极少的信号——3 个多月只有 7 次买入信号、9 笔成交，5 胜 4 负，但盈利因子仍有 2.07。这个测试还是**双周期工程**的好范本：指标在重采样的 H4 框架上计算（368 根信号 K 线），订单在 M15 执行框架（6,129 根）上成交，两套 feed 通过 `resampledata` 挂进同一个

Lane 对实习生们反复念叨一句话："随机指标告诉你，收盘价坐在近期区间的哪个位置。" 这就是 Stochastic 的全部哲学：如果一轮下跌的尾声、收盘价却开始收在近几日区间的上沿，说明空头已经推不动价格了——**收盘位置比价格本身更早泄露拐点**。后来这条思路开枝散叶：Lane 的 %K/%D 演化出中国交易者最爱的 KDJ；Lambert 的 CCI 用典型价偏离均值的标准化距离衡量"极端"；William Blau 则在 1990 年代系统性地把"原始动量 → 多重平滑 → 比值归一"做成了一整个家族（TSI、Ergodic、SM Stochastic）。 + +有趣的是，本仓库这批 MT5

50.22%，盈利因子 1.16，终值微涨到 1,006,404——典型的薄利多销型均值回归，赚的是纪律和点差控制的钱。 + +## 深读二：DiNapoli Stochastic——交易大师的"减速"改造 + +Joe DiNapoli 是斐波那契交易法的旗手，他对 Stochastic 的改造看似简单却改变了信号性格：原始 %K 用 8 期，然后用**递推式指数平滑**连做两次（3

+ +```python +def _three_white_soldiers(self): + if len(self.data) < 4: + return False + avg = self._avg_body() # 近 51 根 K 线的平均实体 + if avg <= 0: + return False + return ( + (float(self.data.close[-3])

and rsi_1 > 60: self.sell(...) +``` + +两个工程细节值得咀嚼：**"长实体"是相对的**——必须大于近期平均实体，而不是绝对点数，这样同一套阈值才能同时适用于平静盘整和暴力行情；**"连续"用中点上移判定**，过滤掉三根大阳线但重心不动的高波动假形态。四个变体里 `ma_period`（平均实体的窗口）也不尽相同：RSI 版用 51、MFI/CCI 版用 13、Stoch 版用 5——移植时连这些细节差异都被原样保留，恰好构成另一个可研究的维度。 + +**对照实验的结果**。四份测试都在同一窗口（XAUUSD M15，2025-12-03 至 2026-03-10，6,129 根 K 线）上运行：RSI 版只触发 1 笔交易，净亏 2,083.40（终值 997,916.60）；MFI 版 7 笔，胜率 42.86%，终值 999,408.80；Stoch 版 4 笔，胜率 25%，终值 999,394.30；CCI 版仅断言了最基本的活动性。三个月窗口内信号稀疏，**结论不是"哪个确认器更好"，而是这套矩阵正是做该研究的正确姿势**——把确认器当唯一变量，数据、成本、断言全部锁死，换一段更长的历史数据即可复用。 + +## 深读二：锤子 + RSI(2)——经典组合的诚实基线 + +[test_0035_candlestick_mean_reversion.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/mean_reversion/test_0035_candlestick_mean_reversion.py) 在 XAUUSD 日线上跑了 2008-2025 整整 18 年：RSI(2) 跌破 5 的极端超卖，再要求锤子或看涨吞没确认，持有 5 天离场。 + +```python +def detect_hammer(open_price, high, low, close): + body = abs(close - open_price) + lower_shadow = pd.concat([open_price,

`abs(final_value - 836509.26) < 0.83` 把这个亏损钉成了基线。它教给你的正是回归测试库的价值观：**形态确认没有自动带来优势，"教科书直觉"必须先过历史数据这一关**。作为练习，试着把 `rsi_oversold` 调回常用的 30、或去掉形态确认只留 RSI(2)，看看断言会怎样崩开。 + +## 深读三：卡尔曼滤波蜡烛——当形态学家遇上状态估计 + +如果不用固定窗口的平均实体，而是让"蜡烛"自己随噪声自适应呢？[test_0186_0951_kalmanfiltercandle.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/mean_reversion/test_0186_0951_kalmanfiltercandle.py) 移植自 MT5 EA，对 open/high/low/close **各跑一条卡尔曼滤波**（`k=1.0`），拼出一根"滤波蜡烛"： + +```python +def next(self): + source_price = indicator_source_price(self.data, 0) + # （首根 K 线的初始化分支从略） + prev_value = float(self.lines.value[-1]) - float(self.p.price_shift_points) + distance = source_price - prev_value + error = prev_value + distance * self.sqrt100 # sqrt(k/100) + self._velocity += distance * self.k100 # k/100 + filtered = error + self._velocity + float(self.p.price_shift_points) + self.lines.value[0] = filtered + +# KalmanFilterCandleIndicator：滤波 OHLC 拼蜡烛，再判色 +# if o < c: color = 2 # 看涨 +# elif o > c: color = 0 # 看跌 +``` + +策略交易"滤波蜡烛的颜色翻转"：翻红开多、翻绿开空，配 1,000 点止损 / 2,000 点止盈。结果很有教育意义：6,127 根 K 线里做了 **497 笔**交易，胜率只有 29.38%，终值 997,343.30——低胜率靠止盈两倍于止损来续命，最终仍略亏。滤波抹掉了噪声，也抹掉了形态本身的节奏，这是所有"平滑反转"系统的共性代价：滤波越强，信号越滞后，翻转越频繁。想救活它，方向不在调 `k`，而在给翻转信号加一道确认（比如上一根滤波蜡烛的斜率），这正好可以借回深读一的确认器矩阵。 + +## 其余策略，快速点将 + +- **复合蜡烛反转**（`test_0229`）：把最多 3 根

佣金）：18 年 148 笔交易，胜率 **66.89%**，终值从 100 万涨到 **2,138,567.90**，夏普 0.566——代价是 30.35% 的最大回撤。高胜率、无止损、吃趋势内回调，这正是 Connors 学派的招牌画像：他反复强调短期均值回归**不要设止损**，用时间离场（这里是 7 日新高）代替价格止损，避免在最恐慌的点位被洗出局。30% 的回撤就是这份哲学的账单，能否接受因人而异。另注意 `close <= rolling(7).min()` 用的是"含当根"的新低，差一个 shift 就是另一个策略。旁边的 [test_0010_double_n_gold.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/mean_reversion/test_0010_double_n_gold.py) 是同一思想把 7 换成可调 N 的变体，断言结果与 0002 完全一致（148

Kaufman 的效率比率（Efficiency

**2,700,065.50**——比不加过滤的裸 RSI 策略好了不止一个档次。ER 的妙处还在于它不是二选一的开关，而是一个连续的"市场质量"刻度：Kaufman 后来的 KAMA（Kaufman Adaptive Moving Average）正是用 ER 去动态调节均线速度——趋势市跑得快、震荡市挪得慢。同一个比率，既能当过滤器（本篇），也能当调速器（KAMA），这是指标设计里"一鱼两吃"的典范。对比第 10 篇里胜率 48% 的蜡烛组合，你会看到"什么时候不交易"往往比"交易什么形态"更值钱。 + +## 其余策略，快速点将 + +- **波动率冲击**（`test_0019`）：波动率百分位低于 60 买入、高于 80

的意图是"小止损博大趋势"，但跟踪止损 15 点意味着价格只要回调 15 点就开始挪止损，步长 45 点又要求新止损价至少比旧价优 45 点才值得撤单重挂，三个参数共同决定了离场的节奏。回测很有教育意义：6,129 根 K 线做了 **3,057 笔**交易（本窗口内 buy_count=0、sell_count=3057——状态机只在翻空时进场），胜率 45.6%，终值

+[test_0010_momentum_rotation_roc.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/momentum/test_0010_momentum_rotation_roc.py) 在金银铂钯四个贵金属上做横截面轮动。打分用三个周期的 ROC 加权混合（权重 0.2/0.3/0.5，长期占比最重）： + +```python +periods = [int(x) for x in params.get('roc_periods', [21, 63, 252])] +weights = [float(x) for x in params.get('roc_weights', [0.2, 0.3, 0.5])] +for period,

60%。原因不难找：四个贵金属彼此相关性极高，"轮动"实际是在同一根趋势线上反复换车，2013-2015 贵金属齐跌时无处分散。回归测试把这个亏损结果钉进断言，价值正在于此：**横截面动量需要真正低相关的资产池**，这不是参数能修好的。它同时示范了信号前置的工程范式——打分、排名、权重全部在 pandas 里预计算成信号列，`next()` 只负责按 flag 下单，回测引擎因此可以放心走向量化快路径。 + +## 深读二：ESG Momentum——动量 × 低波动的正交叠加 +

19.19%，Sharpe 0.90——对比第 13 篇裸时序动量的 23.30% 回撤，低波动过滤确实削掉了最痛的一段。动量负责方向、低波动负责质量，这就是"因子叠加强化"最直观的教材案例。63 天的低频再平衡同样值得注意：它把动量最常见的成本杀手——过度交易——直接锁死，整个 18 年只动了二十几次仓位。 + +## 深读三：52 周新高效应——不突破，只贴近 +

0.57，最大回撤 30.61%。注意一个实现细节：配置里 `lookback_weeks=26`，滚动窗口实际是 26 周（130 个交易日）而非名字里的 52 周——**策略名与参数是两回事，读源码时永远以参数为准**，这也是回归测试把参数写死在文件里的意义。 + +## 其余策略，快速点将 + +- **Alpha 动量**（`test_0017`）：对 IVV 做滚动回归取截距

在 H1 周期（由 M15 重采样而来）上识别三内含涨/跌：一根长阳（阴）线、一根被其包裹的反向小 K 线、再一根收盘突破首根极值的确认 K 线。形态判定是八个布尔条件的直译： + +```python +return ( + older_open > older_close and # 首根阴线 + middle_open < middle_close and # 中间阳线 +

older_high # 确认收盘突破首根高点 +) +``` + +工程上最有看头的是出场——它没有写止损循环，而是把止损止盈直接交给 `buy_bracket` 一组三腿订单： + +```python +sl = close_price - self.p.stop_loss * self.p.point_size # 500 点止损 +tp = close_price + self.p.take_profit * self.p.point_size # 500 点止盈 +orders = self.buy_bracket(size=size, stopprice=sl, limitprice=tp) +``` + +点数 ×0.01 的换算、0.1 手的合法化（lot_min/lot_max/lot_step 夹逼）都忠实还原了 MT5 EA 的习惯。结果：终值 999,745.50（−0.03%），胜率 36.36%，最大回撤仅 0.08%——1:1 的盈亏比配上不足四成的胜率，数学上注定贴地飞行。**入场靠形态、盈亏比靠 bracket，两件事得分开学**；三内含作为一个"确认后再入场"的谨慎形态尚且如此，更激进的单 K 线形态可想而知。 + +## 深读二：多空吞没——最著名形态的成绩单 + +吞没形态是 Nison 体系里知名度最高的反转信号。[test_0010_0588_bullish_bearish_engulfing.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/price_patterns/test_0010_0588_bullish_bearish_engulfing.py) 的判定比教科书还严格——不但实体要包裹，上下影线也要全面覆盖，还要留出 `distance` 点的余量： + +```python +dist = float(self.p.distance) * self._point() +bullish = ( + c0_open < c0_close and # 当根阳线 + c1_open > c1_close and # 前根阴线 + c0_high

数据上，这份"教科书标准实现"终值 990,348.20（−0.97%），**胜率 0.0%**，Sharpe −8.34。一个参考解释：M15 级别的吞没在黄金这种趋势性市场里更多是噪声而非共识翻转——回测的意义就是让这类"图很美、数很难看"的假设现出原形。顺带一提，`shift` 参数把形态检测整体右移一根 K 线，配合 `pending_direction` 的两段式下单（先平后开），EA

年代起就注意到周末效应、月初效应、一月效应这些日历异象；而另一类异象藏在 K 线的缝隙里：开盘价与昨日收盘价之间那条肉眼几乎看不见的跳空缺口，民间谚语说"缺口必回补"，但真实的缺口有三种命运——回补、延续、反转，每种命运背后都有一套可回测的策略。 + +隔夜与日内的分裂同样反直觉：一根日 K

日新低之后出现一根强势高开的阳线，是"底部反转"的教科书信号。这个策略（[test_0001_gap_n_go_fade_from_50_day_low.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/others/test_0001_gap_n_go_fade_from_50_day_low.py)）偏偏反着做：跌势末端的跳空高开更像情绪的一次性宣泄，宣泄完继续跌。它在 setup 出现当日开空，持有 `hold_days=2` 天定时离场。 + +Setup 判定是四道条件的 AND： + +```python +out['prior_day_new_low'] = out['new_50d_low'].shift(1).fillna(0.0) # 昨日刚创 50 日新低 +out['gap_up_abs'] = out['open'] -

(out['close_above_open'] > 0.5) +).astype(float) +``` + +两处工程细节值得抄走：跳空的"显著"用百分比与 ATR 双触发取或——波动大的月份 0.3% 不算事，ATR 那条腿会自动抬高门槛；离场不设止损止盈，纯靠固定持有期，杜绝"扛单等回本"的人性漏洞。回测非常稀疏：18 年 4,588 根 bar 只触发 6 次，3 胜 3 负，终值 1,030,141.98（+3.01%），profit factor 1.56，最大回撤仅 3.27%。它不是印钞机，但每个数字都被断言锁死，是衡量"同思想不同过滤器"的干净起点。 + +## 深读二：Overnight Intraday——把一根日 K 线拆成两个市场 + +这个策略（[test_0037_overnight_intraday.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/others/test_0037_overnight_intraday.py)）的信号朴素到令人怀疑人生： + +```python

天，然后重新评估。`next()` 里就是"信号开仓、计时平仓"两件事。 + +结果：593 笔交易，胜率 56.2%，终值 4,235,224.89（+323.5%），Sharpe 0.64，SQN 3.21——先别激动，看一眼经纪商配置：`margin=0.01, multiplier=100` 的期货模型，等于 10 倍杠杆，最大回撤 30.27% 就是杠杆的代价。这也正是回归测试库的价值：数字不会骗人，但口径会——不知道杠杆就读收益，是回测第一坑。 + +## 深读三：Day of Month Timing——月末那一天的纪律 + +日历效应最容易过拟合的地方，是"哪一天调仓"可以无限微调。这个策略（[test_0026_day_of_month_timing.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/others/test_0026_day_of_month_timing.py)）选择把再平衡钉死在每月最后一个交易日（`signal_day=0`），其余日子一概不动：

3,050,417.26。注意它的逐笔战绩只有 4 胜 16 负——轮动策略的收益来自仓位路径而非单笔胜负，这个口径差异值得每个读回测报告的人记住。 + +## 其余策略，快速点将 + +- **Gap Down**（`test_0040`）：与深读一互为镜像——低开超 1% 做多赌回补，持有 5 日。同是缺口，方向假设完全相反，正好对照。 +- **Monday Drop

0.5：H 接近 1 表示趋势自增强，H 接近 0

Thrust**（`test_0018`）：单工具没有涨跌家数，就用一篮子动量条件构造宽度代理，其 EMA 从低于 0.4 一跃站上 0.615 视作"推进"，持多 20 日。 +- **Fifty Fifty**（`test_0020`）：一半资金永远持有、一半资金跟 200 日均线开关——懒人版的"核心 + 卫星"。 + +## 一条命令跑起来 + +```bash +# 整个分类（69

留下过一句被引用了六十年的观察：价格的大幅变动倾向于紧跟大幅变动，小幅变动倾向于紧跟小幅变动——**波动率聚集**。它意味着市场不是一台参数恒定的机器，而是在"平静"与"狂暴"两种性格之间来回切换。顺着这条路，量化界发展出两套语言：一套用隐马尔可夫模型（HMM）把切换本身建模成隐含状态；另一套用 VIX 这样的"恐慌温度计"直接测量当前体温。还有一个小众但迷人的流派——航天工程师 John

+这是全分类里机器学习浓度最高的策略（[test_0007_0125_hmm_regime_detection.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/volatility_systems/test_0007_0125_hmm_regime_detection.py)）。它假设市场存在三个隐含状态，从三个可观测量里推断：对数收益、20 日年化波动率、60 日动量。每根 bar 用过去 252 日训练一个三状态高斯 HMM，每 63 日重训： + +```python +model = GaussianHMM(n_components=n_states, covariance_type='full', + n_iter=300, random_state=42) # n_states = 3 +model.fit(train_std) +labels = _label_states(model, train_std) # 按各状态平均标准化收益标注 BULL/BEAR/NEUTRAL + +current_state = int(state_seq[-1]) +current_confidence = float(proba[-1, current_state]) +consistent = len(recent_states) >= smoothing_window and \ + all(s == current_state for s in recent_states[-smoothing_window:]) # 连续 5 日同状态 + +signed_target = 0.0 +if current_confidence >= confidence_threshold and consistent: # 置信度 ≥ 0.55 + if current_label == 'BULL': + signed_target = min(1.0, 1.0 * current_confidence) # 牛市做多，仓位随置信度 + elif current_label == 'BEAR': + signed_target = max(-0.5, -0.5 * current_confidence) # 熊市小空 +``` + +注意两处防御：HMM 的状态编号是无意义的（0/1/2 每次重训都可能换含义），所以先按各状态的平均收益重标注成 BULL/BEAR/NEUTRAL；状态信号噪声大，所以加了"置信度过阈值 + 连续 5 日同一状态"的双重过滤，宁迟勿错。回测窗口 2024-2025 共 205 根 bar，重训 4 次，信号翻转 27 次但真正换仓仅 2 笔、两笔全胜，终值 1,014,553.76（+1.46%），SQN 4.76。工程上还有一处值得抄：文件开头 `pytest.importorskip("hmmlearn")`——可选 ML 依赖缺席时整模块优雅跳过，而不是让 CI 红一片。 + +## 深读二：Bollinger Band Breakout——不对称的 σ 通道 + +布林带突破人人都写得出，但参数的"不对称"才是这个版本（[test_0021_bollinger_band_breakout.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/volatility_systems/test_0021_bollinger_band_breakout.py)）的灵魂： + +```python +out['bb_middle'] = out['close'].rolling(bb_period).mean() # bb_period = 100 +out['bb_std'] = out['close'].rolling(bb_period).std() +out['bb_upper_entry'] = out['bb_middle'] + entry_dev * out['bb_std'] # +3.0σ 才入场 +out['bb_lower_exit'] = out['bb_middle'] - exit_dev * out['bb_std'] # 跌破 -1.0σ 才离场 +out['entry_signal'] = (out['close'] > out['bb_upper_entry']).astype(float) +out['exit_signal'] = (out['close'] < out['bb_lower_exit']).astype(float) +``` + +入场要冲破 3 倍标准差——18 年的日线数据里这种事只发生 7 次；离场却只要求跌破中轨下方 1 倍标准差。门槛一高一低之间，给了趋势足够的呼吸空间，代价是回吐。结果是一张教科书式的低频趋势画像：7 次开仓仅 3 胜，胜率 42.9%，但 profit factor 2.97，终值 3,076,810.25（+207.7%），最大回撤 23.1%。**低胜率 × 高盈亏比**，与深读一的高胜率低换手恰好构成趋势策略的两副面孔。 + +## 深读三：Fisher Cyber Cycle——Ehlers 的信号处理流派 + +多数指标是统计量，Ehlers 的指标是滤波器。这个 M15 策略（[test_0019_fisher_cyber_cycle.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/volatility_systems/test_0019_fisher_cyber_cycle.py)）先把 (high+low)/2 平滑、再经二阶超级平滑器提取循环分量，然后把归一化后的循环值做 Fisher 变换——把任意分布拉成近似高斯，拐点因此变得锐利： + +```python +k0 = (1.0 - 0.5 * alpha) ** 2 # alpha = 0.07 +k2 = 2.0 * (1.0 - alpha) +k3 = (1.0 - alpha) ** 2 +smooth[bar] =

+value1[bar] = (cycle[bar] - ll) / (hh - ll) # length=8 窗口内归一化 +weighted = (4.0*vals[-1] + 3.0*vals[-2] + 2.0*vals[-3] + vals[-4]) / 10.0 +scaled = 1.98 * (weighted - 0.5) +scaled = min(max(scaled,

分钟重采样）上计算、订单在 M15 上执行，配 1000/2000 固定点数止损止盈。三个月 18 笔交易 7 胜 11 负，终值 996,022.30（-0.40%）。亏损的基线同样被断言钉死——它证明的不是"Ehlers 不行"，而是这套参数在这段行情里没有正期望，给你留出了改进的对照面。钳位那一行 `min(max(scaled, -0.999999), 0.999999)` 是数值工程的细节美：Fisher 变换在 ±1 处发散，一行代码挡住一次 NaN 崩溃。 + +## 其余策略，快速点将 + +- **VIX SPX Divergence**（`test_0011`）：没有真 VIX 数据就用历史波动率代理——价格创新高、波动率却在上升、价波相关性断裂，三信号共振时做空，周一与波动率尖峰放大权重。 +- **Adaptive VIX MA**（`test_0012`）：波动率在 500 日里的百分位直接决定 EMA 的 α（常数 4.6）——越极端的波动，均线跟得越紧。 +- **Gold Volatility Position**（`test_0005`）：波动率分位 < 0.2 满仓、> 0.8 半仓、其余 75%——"别人恐惧我贪婪"的量化直译。 +- **Volatility Long Memory**（`test_0010`）：对波动率序列本身算 Hurst——趋势化的波动跟均线，反持续的波动做反转。 +- **Correlation Regime**（`test_0015`）：股债相关性是免费的风险气压计——显著为负配股票（risk-on），转正配债券（risk-off），中间地带均衡配置。 + +## 一条命令跑起来 + +```bash +# 整个分类（32 个策略）

高低轨周期刻意不对称（40 vs 5），上轨慢、下轨快，多头给的容忍比空头大。三个月 6,071 根 M15 跑出 687 笔、352 胜 335 负，终值 1,038,763.00（+3.88%）——高频微利型，收益全靠胜率优势一点点磨出来。 + +## 深读二：MQL5 Wizard MACD + Parabolic SAR——评分制的教科书与反面教材 + +MQL5 Wizard 的标准玩法是"信号模块投票"：每个模块输出 ±100 分乘以权重，总分过线开仓。这个移植（[test_0020_mql5_wizard_macd_parabolic_sar.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/multi_indicator_system/test_0020_mql5_wizard_macd_parabolic_sar.py)）用

单独就能开门，PSAR 只是礼仪性投票**。评分制表面平滑了分歧，权重却决定了谁在独裁。回测给了它一记响亮的耳光：3,077 笔交易、48.6% 胜率、profit factor 0.915、终值 910,005.00（-9.0%），在零佣金的 M15 数据上照样稳定亏——M15

Wave）、五指标感知机（Perceptron）这样的重装部队。每加一个旋钮，拟合历史的能力就强一分，样本外的可靠度就暗降一分。这正是回归测试库存在的意义：**先把每个组合的原始成绩钉死在基线里，任何"优化"都必须在相同数据、相同口径下与前作硬碰硬**。 + +## 其余策略，快速点将 + +- **Kaufman Efficiency Ratio**（`test_0001`）：效率比 ER =

+这是全分类最"原教旨"的一个策略（[test_0008_0103_sell_in_may.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/calendar_effects/test_0008_0103_sell_in_may.py)）：规则只有一条——11 月第一个交易日附近买入，5 月第一个交易日附近卖出，其余时间空仓。信号生成干净得像教科书： + +```python +out['month'] = out.index.month +buy_signal = out['month'] == buy_month # buy_month = 11 +sell_signal = out['month'] == sell_month # sell_month = 5 +prev_month = out['month'].shift(1) +buy_entry = (prev_month != buy_month) & buy_signal # 仅在"进入11月"那根K线触发 +sell_entry = (prev_month != sell_month) & sell_signal +out['holding'] = ((out['month'] >= buy_month) | (out['month'] <= 4)).astype(float) +``` + +注意 `holding` 的写法：11、12 月用 `>= 11` 抓，1-4 月用 `<= 4` 抓——跨年区间的布尔逻辑是日历策略最常写错的地方。策略侧的 `next()` 只在信号翻转时下单：空仓遇 `buy_signal` 全仓买入，持仓遇 `sell_signal` 平仓。 + +**回测结果**：XAUUSD 日线 2008-2025、初始 100 万、万二佣金加 1% 保证金，17 年只做了 18 笔交易，胜 12 负 6（胜率 66.7%），终值 2,875,338——总收益 +187.5%，利润因子 4.93，最大回撤 28.9%，Sharpe 0.546。这些数字不是宣传语，是测试断言：`abs(final_value - 2875338.15) < 2.88` 之类一行行钉在文件里。当然要诚实地说：黄金本身 2008-2025 走了大牛市，这个策略吃到的相当一部分是 beta；它的真正价值在于提供了"全年持有 vs 只持 6 个月"的对照起点——仓库里另有 `test_0015_0366` 独立实现可供对拍。 + +## 深读二：Turn of Month——把"月初月末"变成窗口函数 + +换月效应（Turn of Month）指资产收益集中在月末最后几天与月初头几天的现象，主流解释包括工资/养老金定投现金流与机构再平衡。本篇的实现（[test_0020_0407_turn_of_month_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/calendar_effects/test_0020_0407_turn_of_month_strategy.py)）用 groupby-rank 把窗口定义得非常精确： + +```python +fwd_rank = pd.Series(range(len(out)), index=out.index).groupby(current_period).transform( + lambda x: x.rank(method='first')) +rev_rank = pd.Series(range(len(out)), index=out.index).groupby(current_period).transform( + lambda x: x.rank(ascending=False, method='first')) +out['is_month_end_window'] = (rev_rank <= last_days).astype(float) # last_days = 3 +out['is_month_start_window'] = (fwd_rank <= first_days).astype(float) # first_days = 3 +in_window = (out['is_month_end_window'] > 0.5) | (out['is_month_start_window'] > 0.5) +out['entry_signal'] = (in_window & (~prev_in_window)).astype(float) +out['exit_signal'] = ((~in_window) & prev_in_window).astype(float) +``` + +策略侧入场即 `order_target_percent(target=1.0)` 满仓，同时挂 2% 百分比止损：`self.stop_price = close * (1.0 - self.p.stop_loss_pct)`——这是"日历窗口+风控"的标准工程组合。 + +**回测结果**：同一份 XAUUSD 日线，4,638 根 K 线里有 1,296 根处于窗口内（约 28% 的时间），共 210 笔交易、115 胜 94 负（胜率 54.8%），终值 2,000,333（+100.0%），利润因子 1.50，Sharpe 0.562。只用不到三成的在市时间拿到这个结果，正是换月效应的卖点。文件里还有个细节值得学：pandas 3.x 的 `fillna(False)` 不再隐式降型，作者特意保持 object dtype 以保证 2.x/3.x 信号一致——版本兼容意识写进了注释。 + +## 深读三：FOMC 效应——事件驱动的日历策略 + +日历效应不只"月份"，还包括"事件日"。[test_0022_0016_gold_fomc_effect.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/calendar_effects/test_0022_0016_gold_fomc_effect.py) 研究美联储议息会议前后的黄金漂移。由于回测无法拿到真实 FOMC 日历，它用代理规则合成： + +```python +FOMC_MONTHS = (1, 3, 5, 6, 7, 9, 11, 12) +# 取每月第 3 个周三作为 FOMC 代理日，再对齐到最近的交易日 +stop_pct = float(np.clip(stop_vol_multiplier * stop_pct * math.sqrt(pre_event_days), + min_stop_pct, max_stop_pct)) # 2.0×波动×√5，夹在 [1%, 5%] +if historical_drift > 0 and current_trend > 0: + direction = 1 # 历史会前漂移为正且当前趋势向上，才做多 +``` + +仓位管理很克制：每次事件只用 3% 名义敞口（`event_position_pct=0.03`），连亏 3 次后暂停 1 个事件。**回测结果**：69 笔交易，33 胜 36 负，终值 994,992（-0.50%），Sharpe -0.17，最大回撤仅 1.29%。亏钱，但亏得明明白白——小仓位+严止损让它成了"低风险地验证一个不成立假设"的范本。想要正收益版本？同目录的 `test_0024`（非农新高）与 `test_0026`（大选前漂移）提供了对照。 + +## 其余策略，快速点将 + +- **季节性拼图**（`test_0012_0275` / `test_0013_0281`）：季节翻转与多窗口复合，把单月效应组装成组合信号。 +- **商品季节性抢跑**（`test_0019_0406`，GLD 数据）：在季节性需求兑现前提前布局。 +-

线数出的衰竭信号 + +Tom DeMark 的 TD Sequential 是技术分析界少见的"有完整算法规范"的指标，被交易员用来捕捉趋势衰竭：价格不会永远跌，但连续跌够 9 根、再熬过 13 格倒数，空头也该累了。仓库实现（[test_65_td_sequential_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/misc/test_65_td_sequential_strategy.py)）忠实还原了两段式结构。Setup 阶段：连续 9 根收盘价低于 4 根之前的收盘（`candles_past_to_compare=4`）： + +```python +if len(self.dataclose) > self.p.candles_past_to_compare: + # 买方向触发：本次收盘 < 4 期前收盘，且上一次不满足 + if (self.dataclose[0] < self.dataclose[-self.p.candles_past_to_compare] and + self.dataclose[-1] > self.dataclose[-(self.p.candles_past_to_compare + 1)]): + self.buyTrig = True + self.sellTrig = False + # Setup 计数：连续满足则累加 + if self.dataclose[0] < self.dataclose[-self.p.candles_past_to_compare] and self.buyTrig: + self.tdsl += 1 +``` + +Countdown 阶段在 Setup 计满 9 后启动，直到第 13 格、且收盘价跌破第 8 格低点才确认"理想买点"： + +```python +if self.buyCountdown == 8: + self.buyVal = countdown_compare # 记录第 8 格的价格 +elif self.buyCountdown == 13: + if self.dataprimary.low[0] <= self.buyVal: + self.idealBuySig = True + if not self.position: + self.buy(size=10) # 理想买点，做多 + self.buySetup = False + self.buyCountdown = 0 +``` + +实现里还带着 DeMark 体系的各种取消条款（`cancel_1/2/3`、`recycle_12`）与激进倒数开关（`aggressive_countdown`）——参数就是这套方法的完整词汇表。**回测结果**：ORCL 2010-2014、10 万本金、0.1% 佣金，1,257 根 K 线后终值 100,002.91——基本打平。测试用 `runonce` True/False 双参数化跑两遍并断言同一组数字，指标基准锁到小数点后六位（Sharpe 0.022949…）。衰竭计数在单只股票上不赚钱，但作为"复杂状态机的工程化样板"无价。 + +## 深读二：Pinkfish——两根 K 线的诚实 + +如果说 TD Sequential 是"繁"，Pinkfish 挑战就是"简"的极致（[test_46_pinkfish_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/misc/test_46_pinkfish_strategy.py)）：创 20 日新高就买，拿满 2 根 K 线，无条件卖。全部交易逻辑： + +```python +def next(self): + self.bar_num += 1 + if not self.position: + if self.data.high[0] >= self.highest[0]: # 当根最高触及 20 日最高 + self.buy() + self.inmarket = len(self) + else: + if (len(self) - self.inmarket) >= self.p.sellafter: # 持有 2 根 + self.sell() +``` + +注意它和海龟式突破的区别：没有出场通道、没有止损，出场只看日历——"到了就走"。**回测结果**：YHOO 2005-2006、5 万本金、固定 100 股，484 根 K 线后终值 49,739.00，Sharpe -2.5197，年化 -0.26%。测试把这组难看的数字焊死在断言里。为什么值得读？因为它是最好的"假设检验教具"：动量入场+随机持有期，在震荡市里就是磨损机器；把 `sellafter` 从 2 改成 20 会不会不一样？改成 trailing stop 呢？每改一处，断言立刻告诉你代价——这正是回归测试库教人研究的方式。 + +## 深读三：滑点验证——策略目录里的"地基" + +第三读不属于任何交易思想，却决定所有回测的可信度。[test_47_slippage_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/misc/test_47_slippage_strategy.py) 内置一个标准 SMA(10/30) 金叉策略，但它存在的意义是给 `cerebro.broker.set_slippage_*` 系列接口当载体：同一策略在零滑点与固定/百分比滑点下的成交价差、净值差被逐一断言。同族的还有佣金方案矩阵（`test_54`）、writer 落盘（`test_60`）、Calmar/VWR/Sharpe 的 analyzers 数值基线（`test_49/50/57`）、PSAR 指标（`test_55`）与 Sizer（`test_56`）。它们与策略共用同一套 Cerebro 管线，因此任何引擎改动若影响成交、计费或指标计算，这些测试会在策略测试之前先报警——**misc 分类因此是仓库的"策略+框架验证"双重角色承担者**，这不是杂物间，是承重墙。 + +## 其余策略，快速点将 + +- **BTFD

(out["close"] > out["ma"]).astype(float) +# 每 rebalance_days = 63 天打一次再平衡标记 +``` + +策略侧在再平衡日按趋势调仓，偏离超过 10% 才动手： + +```python +target_weight = self.p.equity_weight if trend_up else 0.30 # 0.60 / 0.30 +if abs(current_size - target_size) > target_size * 0.1: + self.pending_order = self.close() # 先平后调 +``` + +**回测结果**：XAUUSD 日线 2008-2025、100 万本金，17 年只调仓 19 次，13 胜 6 负（胜率 68.4%），终值 2,542,114（+154.2%），利润因子 5.24，最大回撤仅 11.9%，Sharpe 0.770。低频+趋势过滤的组合拳，回撤控制远好于买入持有（对照全目录：简单持有同段黄金的回撤要大得多）。想看"不加过滤的 60/40"长什么样？`test_0002` 与 `test_0003` 提供了多资产版本对照。 + +## 深读二：永久组合——25%×4 的极简哲学 + +Harry Browne 1981 年提出永久组合（Permanent Portfolio）：股票、债券、黄金、现金各 25%，赌的是"未来永远处于繁荣/衰退/通胀/通缩四态之一，且每态总有一类资产受益"。实现（[test_0007_permanent_portfolio.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/asset_allocation/test_0007_permanent_portfolio.py)）用 GLD/IVV/IEF 三只 ETF 日线加上现金腿： + +```python +params = dict( + target_weights={'GLD': 0.25, 'IVV': 0.25, 'IEF': 0.25}, + cash_weight=0.25, + rebalance_threshold=0.05, # 一般资产漂移带 5% + gold_rebalance_threshold=0.02, # 黄金波动大，给更紧的 2% +) +``` + +再平衡触发是"年度 + 阈值"双轨制，这正是实盘配置的标准工程： + +```python +if current_year != self.last_rebalance_year: + self._rebalance() # 每年第一个交易日强制再平衡 + return +if self._needs_threshold_rebalance(): # 漂移超带，提前纠偏 + self.threshold_rebalance_count += 1 + self._rebalance() +``` + +**回测结果**：2008-2025、4,518 个交易日，共触发 50 次再平衡（其中 32 次是阈值触发——黄金腿的 2% 紧带果然忙碌），终值 4,268,547（+326.9%），年化 8.43%，最大回撤 32.3%，Sharpe 0.659。注意：这段区间黄金与美股都是大牛，数字偏乐观；但"金腿用更紧的漂移带"这类细节，是教科书不写、回测才会告诉你的。 + +## 深读三：CPPI——用数学保本 + +CPPI（Constant Proportion Portfolio Insurance，常数比例组合保险）是 1980 年代为"保本基金"发明的技术：设定一条不能跌破的底线（floor），组合市值高出底线的部分叫"垫子"（cushion），风险资产敞口 = 垫子 × 乘数。涨得越多垫子越厚、敞口越大；跌的时候垫子收缩、自动减仓，理论上永不击穿底线。实现（[test_0017_cppi_portfolio_insurance.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/asset_allocation/test_0017_cppi_portfolio_insurance.py)）： + +```python +running_max = out['close'].cummax() +floor_value = running_max * floor_pct # floor_pct = 0.8，峰值的 80% +out['cushion_pct'] = (out['close'] - floor_value) / out['close'] +out['exposure'] = (out['cushion_pct'] * cppi_mult).clip(0.0, 1.0) # multiplier = 3.0 +``` + +每 21 天再平衡一次，敞口高于 10% 才建仓、低于 5% 清仓。**回测结果**：35 笔交易、14 胜 20 负（胜率只有 40%），终值 1,533,999（+53.4%），Sharpe 0.447。胜率不到一半却稳稳盈利——盈亏不对称才是 CPPI 的性格：3 倍乘数让上涨时垫子迅速放大敞口，下跌时快速缩表。它的敌人是"Gap 风险"（一步跳空击穿底线），日线级 20% 的缓冲垫在 2008 式崩盘里是否够用，值得你自己改参数验证。 + +## 其余策略，快速点将 + +- **HRP/HERC**（`test_0012` / `test_0015`）：Lopez de Prado 在《Advances in Financial

里一页看完。第一步定义对数价差（固定对冲比率 `hedge_ratio=1.0`）： + +```python +def _spread(self): + gold_price = max(float(self.gold.close[0]), 1e-6) + silver_price = max(float(self.silver.close[0]), 1e-6) + return math.log(gold_price) - float(self.p.hedge_ratio) * math.log(silver_price) +``` + +第二步对价差做 192 根 K 线的滚动 z-score；第三步用三条阈值管理头寸： + +```python +if not has_position: + if zscore <=

H1 数据 2025-07 至 2025-12 共 2,986 根 K 线，102 笔配对交易，46 胜 56 负（胜率 45.1%），终值 990,238（-0.98%），Sharpe -1.91，最大回撤仅 1.67%。小仓位让亏损可控，但固定 `hedge_ratio=1.0` 是明显短板——金银比中枢过去二十年从 60 漂到 120，静态比率必然吃亏，这正好引出第二读。 + +## 深读二：卡尔曼滤波——让对冲比率自己动起来 + +如果价差关系会漂移，就把对冲比率 β 做成状态量在线估计。[test_0001_gold_kalman_filter_pairs_trading.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/pairs_trading/test_0001_gold_kalman_filter_pairs_trading.py) 用一维卡尔曼滤波逐根更新"1 盎司金对多少盎司银"： + +```python +def update(self, price_a, price_b): + beta_pred = self.beta + P_pred = self.P + self.Q # 过程噪声 Q = 0.0005 + denominator = P_pred * price_b * price_b + self.R #

才允许开仓——关系不稳时宁可不做： + +```python +if self.current_zscore <= -float(self.p.entry_threshold) and is_stable: + self._submit_pair_orders(1, price_a, price_b) # entry = 2.0，exit = 0.35，stop = 3.25 +``` + +**回测结果**：同一份 H1 数据，103 次平仓（61 胜 42 负，胜率 59.2%，含 9 次止损），终值 997,507（-0.25%）。与深读一对照：胜率从 45% 提到 59%，回撤更小——动态 β 的价值不在多赚，而在少错。 + +## 深读三：Copula 配对——不只看价差，还看"一起极端吗" + +z-score 隐含假设价差服从椭圆分布，但金银真正的耦合藏在尾部：恐慌时金涨银跌可以同时极端。Copula 直接对"联合分布"建模（[test_0007_copula_pairs_trading.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/pairs_trading/test_0007_copula_pairs_trading.py)）：先用 252 天滚动窗口的 Kendall τ 估计 Clayton copula 参数（Clayton 擅长捕捉下尾依赖），再算"给定金的当日分位，银的条件概率"： + +```python +tau = stats.kendalltau(u, v).correlation +theta = 2.0 * tau / max(1e-6, 1.0 - tau) # τ → θ +def clayton_conditional(u, v, theta): + term1 = u ** (-(theta + 1.0)) + term2 = (u ** (-theta) + v ** (-theta) - 1.0) ** (-(theta + 1.0) / theta) + return term1 * term2 # P(V<=v | U=u) +``` + +条件概率的读法：`P(V<=v|U=u)` 接近 0，说明"金没怎么动、银却相对暴跌"——银被错杀，买银卖金（腿权按滚动 β 对冲）。信号阈值： + +```python +if prob_v_given_u < entry_threshold: # 0.05，银显著便宜 + position = 1 +elif prob_v_given_u > 1.0 - entry_threshold: # 银显著贵 + position = -1 +if abs(prob_v_given_u - 0.5) <= exit_band: # 0.10，回到中性带平仓 + position = 0 +``` + +**回测结果**：金银日线 2018-2025 共 1,812 根，292 笔交易 136 胜（胜率 46.6%），终值 986,607（-1.34%），Sharpe -0.24。三个深读策略全都没赚大钱，这不是意外：价差越来越有效的市场里，简单的统计套利早已不是印钞机。回归测试库如实收录，正是为了给"配对交易容易吗"提供诚实的基线答案——改进方向（更长持有期、跨品种篮子、成本模型）在其余策略里各有示例。 + +## 其余策略，快速点将 + +- **距离配对**（`test_0013`）：Gatev 1999

n_init=10) # n_clusters=4 +train_labels = fitted_model.fit_predict(train_x) +cluster_stats = train.groupby("cluster")["next_intraday_return"].agg(["mean", "count"]) +benchmark = float(train["next_intraday_return"].mean()) +eligible = cluster_stats[cluster_stats["count"] >= min_cluster_size] # min_cluster_size=20 +if not eligible.empty and float(eligible.iloc[0]["mean"]) > benchmark: + active_cluster = float(eligible.index[0]) +``` + +当当前 K 线被预测落入活跃簇，次日开盘买入、当日收盘前强制平仓。信号经过 `shift(1)` 对齐，避免了前视偏差。结果如何？2022-2025 年 XAUUSD 上 262 个交易日、70 笔交易——**胜 0 笔，负 70 笔**。测试断言 `win_count == 0`、`loss_count == 70`，把这场全败钉成了基线。训练窗内簇的统计优势一到样本外就蒸发，这是无监督聚类在低信噪比金融数据上的典型过拟合样本，比任何教科书说教都直观。 + +## 深读三：Reinforcement Learning——q_score 不是 Q 值 + +[test_0004_reinforcement_learning.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/machine_learning/test_0004_reinforcement_learning.py) 名字最唬人，内核却极简。它计算一个"q_score"——RSI 偏离 50 的归一值与价格偏离 50 日均线比例的均值： + +```python +ma = out['close'].rolling(ma_period).mean() # ma_period = 50 +rsi_norm = (out['rsi'] - 50) / 50.0 # rsi_period = 14 +trend = (out['close'] - ma) / ma +out['q_score'] = (rsi_norm + trend) / 2.0 +``` + +交易规则：空仓时 `q > 0.2` 买入，持仓时 `q < -0.2` 平仓。没有环境、没有奖励更新、没有 Bellman 方程——它是"强化学习式"的状态-动作映射，而非真正的 RL。工程点评：真 RL 的回测几乎不可能做成确定性回归（训练本身的随机性就会让每次结果漂移），而这种"冻结的决策函数"保留了 RL 的形，丢掉了不可复现的魂。它的基线同样老实：56 笔交易胜率 41.07%，终值 1,956,006.56（+95.60%），最大回撤 44.85%，Sharpe 0.348——赚得多，颠簸也大。 + +## 其余策略，快速点将 + +-

EURUSD、AUDUSD、NZDUSD、GBPUSD 四个货币对，但信号全部来自两个不交易的宏观代理：IVV（标普 500 ETF，增长代理）与 IEF（国债 ETF，利率代理）。因子构造只有几行： + +```python +growth_factor = _zscore(ivv['close'].pct_change(macro_lookback), zscore_lookback) #

upper=signal_threshold) / max(signal_threshold, 1e-6) * max_pair_weight +``` + +设计有两处值得咀嚼。其一，**利率因子取负号**：债券上涨（收益率下行）→ 利率因子为正 → 加仓商品货币——这正是"利率→持仓成本→价格"链条的向量化表达。其二，**beta 缩放**：AUDUSD/NZDUSD 作为典型商品货币 beta=1.0 拿满宏观信号，EURUSD 0.6、GBPUSD 0.8 逐级打折；信号再截断在 ±0.5、映射到单品种 ±25% 权重上限，每 21 个交易日调一次仓。risk-on 体制下高贝塔货币被抬高，risk-off 下削减甚至反向——一套杠杆随宏观状态呼吸的机器。基线：2008-2025 年 4,331 根日线、259 笔交易，终值 1,040,485.14（+4.05%），盈利因子

报告，把持仓拆成商业（套保者）与非商业（投机者）。经典假设：商业头寸是"聪明钱"，投机头寸是待收割的"群众"。[test_0004_gold_cot.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/commodity_currency/test_0004_gold_cot.py) 把这个假设写成 156 周（三年）滚动 z 值的极端判定： + +```python +out['commercial_z'] = (cot_weekly['commercial_net'] - commercial_mean) / commercial_std # zscore_window_weeks = 156 +out['speculator_z'] = (cot_weekly['speculator_net'] - spec_mean) / spec_std +long_entry = (out['commercial_z'] >= extreme_threshold) & (out['speculator_z'] <= -extreme_threshold) # ±2.0 +long_exit = (out['commercial_z'] < exit_threshold) & (out['speculator_z'] > -exit_threshold) # ±1.0 +``` + +商业极端做多且投机极端做空时入场，两组 z 值向中性回归时离场。仓位随极端程度缩放：基础 3%、上限 5%，另有 3% 止损与"连亏 3 次暂停 4 周"的冷却。工程上这份测试尤其扎实：日线 XAUUSD 重采样到 W-FRI 周线与 CFTC 数据对齐得到 888 根可用 K 线，COT 数据本地缓存、缺失时自动从 CFTC 历史归档下载。结果同样诚实：22 笔交易胜率 36.36%，终值 997,205.05（-0.28%），盈利因子 0.749——"聪明钱"假设在这 20 年黄金上没有兑现超额收益，基线把它如实记录。 + +## 深读三：实际利率信号——用 ETF 对数比率代理实际利率 + +实际利率 = 名义利率 −

12%，当前波动越高仓位越低，并截断在 [0.25, 1.0]： + +```python +if current_vol > 0: + vol_position = self.p.target_vol / current_vol # target_vol = 0.12 + return max(0.25, min(1.0, vol_position)) +``` + +第二层是回撤分级：价格相对滚动高点的回撤（`(close - cummax) / cummax`）每突破一档阈值，仓位系数降一级（文档口径 3%/6%/10% 对应 1.0/0.75/0.5/0.25）： + +```python +if drawdown < -self.p.dd_threshold_1: # 0.03 + return self.p.position_level_1 # 1.0 +elif drawdown < -self.p.dd_threshold_2: # 0.06 + return self.p.position_level_2 # 0.75 +elif drawdown < -self.p.dd_threshold_3: # 0.10 + return self.p.position_level_3 # 0.5 +else: + return self.p.position_level_4 # 0.25 +``` + +两层取 `min` 后，还要过平滑与再平衡带两道缓冲： + +```python +target_position = min(dd_position, vol_position) +smoothed_position = (self.current_position_pct * (1 - self.p.smoothing_factor) + + target_position * self.p.smoothing_factor) # smoothing_factor = 0.15 +if abs(smoothed_position - self.current_position_pct) > 0.05: # 变化超 5% 才动手 + ... self.order_target_size(target=target_size) +``` + +**工程点评（本篇最重要的一段）**：仔细读上面阶梯的分支顺序——由于 `drawdown` 恒为非正值，`drawdown < -0.03` 一旦成立就直接返回 1.0，0.75/0.5 两档实际不可达；浅回撤反而落入 else 拿 0.25。迁移基线锁定的正是这份代码的**真实行为**而非文档意图——2008-2025 年 4,618 根日线、289 次再平衡、终值 2,732,100.12（+173.21%）、Sharpe 0.616、最大回撤 31.43%。这正是断言基线的价值：如果你修复这个阶梯顺序，基线会立刻变红，提醒你"改动"本身需要被审视与重新记录，而不是无声漂移。 + +## 深读二：Tail Risk MA Warning——10 月均线的月度体制开关 + +2008 年金融危机后，"跌破 10 月均线就减仓"从期货老手的土办法升格为学术文献里的尾部风险缓解模型（Meb Faber 的经典研究用的正是 10

+仓库里的实现（[test_105_donchian_channel_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/breakout/test_105_donchian_channel_strategy.py)）干净到可以用 20 行讲清楚： + +```python +class DonchianChannelStrategy(bt.Strategy): + params = dict(stake=10, period=20) + + def __init__(self): + self.highest = bt.indicators.Highest(self.data.high, period=self.p.period) + self.lowest = bt.indicators.Lowest(self.data.low, period=self.p.period) + + def next(self): + if not self.position: + if self.data.close[0] > self.highest[-1]: # 突破上轨，买入 + self.order = self.buy(size=self.p.stake) + else: + if self.data.close[0] < self.lowest[-1]: # 跌破下轨，离场 + self.order = self.close() +``` + +注意 `self.highest[-1]` 的 `-1`：比较的是**上一根 K 线**的通道值，避免用"当根最高价突破当根最高价"的自我指涉——这是新手常犯的偏差之一。 + +**诚实的回测结果**。这个朴素版本在 ORCL 2010-2014 数据上、计入 0.1% 佣金后，终值 99,965.62（初始 100,000）——**略亏**。测试断言 `abs(final_value - 99965.62) < 0.01`，把这个"不赚钱"钉死成了基线。这正是回归测试库的价值观：**策略不是用来表演的，是用来比较的**。没有过滤的裸突破在震荡市会被反复打脸；你在后续篇目会看到加一个 ADX 趋势过滤、或叠加成交量确认后，同一思想可以脱胎换骨。 + +## 深读二：Dual Thrust——期货日内突破的标配 + +Dual Thrust 是国内外期货日内交易流传最广的策略框架之一（[test_09_dual_thrust_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/breakout/test_09_dual_thrust_strategy.py)）。它在玻璃期货 FG889 分钟线上运行，分三步： + +**第一步：用过去 N 日（默认 10 日）的波动构造 Range。** + +```python +hh = max(day_high_list[-look_back:]) # N 日最高价 +lc = min(day_close_list[-look_back:]) # N 日最低收盘价 +hc = max(day_close_list[-look_back:]) # N 日最高收盘价 +ll = min(day_low_list[-look_back:]) # N 日最低价 +range_price = max(hh - lc, hc - ll) # 取两者较大值，更保守 +``` + +**第二步：以当日开盘价为锚，上下各偏移 k 倍 Range 得到买卖触发线。** + +```python +upper_line = now_open + k1 * range_price # k1 = 0.5 +lower_line = now_open - k2 * range_price # k2 = 0.5 +``` + +**第三步：盘中触及轨道就入场，方向反转直接反手，14:55 强制平仓隔夜清零。** + +这套设计的精妙在于：开盘价锚定让轨道随每天的位置自适应，Range 又随波动率伸缩——波动大时轨道更宽、减少假突破；`max(HH-LC, HC-LL)` 的取法让波段估计偏保守。Dual Thrust 也是理解中国期货市场交易时段的好例子：代码里夜盘 21:00-23:00 与日盘 9:00-11:00 的时段判断，正是国内品种的真实节奏。 + +## 深读三：R-Breaker——一套价位，两种逻辑 + +如果说 Dual Thrust 是"单边追击"，R-Breaker（[test_10_r_breaker_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/breakout/test_10_r_breaker_strategy.py)）则是**趋势与反转的双面手**——它常年出现在国内外日内策略榜单上，被戏称为"日内交易者的瑞士军刀"。 + +它用昨日的高（H）、低（L）、收（C）推算五个价位： + +```python +pivot = (pre_high + pre_low + pre_close) / 3 +r1 = pivot + 0.5 * (pre_high - pre_low) # 观察阻力 +r3 = pivot + 1.0 * (pre_high - pre_low) # 突破阻力 +s1 = pivot - 0.5 * (pre_high - pre_low) # 观察支撑 +s3 = pivot - 1.0 * (pre_high - pre_low) # 突破支撑 +``` + +两套规则共享这组价位： + +- **趋势模式**：空仓时，收盘价突破 R3 追多、跌破 S3 追空——认为强突破会延续； +- **反转模式**：持多时若价格回落跌破 R1（涨不动了），立即平多并**反手开空**；持空时升破 S1 则平空反手做多。 + +最后同样 14:55 清仓。趋势模式赚"突破后的一波流"，反转模式赚"假突破的回马枪"——同一组价位，涨跌两种剧本都有预案，这是 R-Breaker 长盛不衰的原因。 + +测试工程上还有一处值得注意：它使用 `ComminfoFuturesPercent` 按 10% 保证金、10 倍乘数给螺纹钢定价，从 50,000 起步——日内期货策略的保证金与合约乘数处理，模板拿来就能改。 + +## 其余三席，快速点将 + +- **量价突破**（`test_115`）：突破必须有量。成交量显著高于其均线时才认 entry，RSI 超买或达到最大持有期离场——把"放量验证"这个古老直觉工程化。 +- **价格通道**（`test_117`）：Turtle 家族的极简变体——创 N 日新高做多、跌破 M 日新低平仓。入场周期 N 与出场周期 M 分离，是所有通道策略可调的第一个旋钮。 +- **Donchian backhacker 版**（`test_66`）：同一思想的另一份参数化实现，适合用来对照"同一规则、不同实现"的工程差异。 + +## 一条命令跑起来 + +```bash +# 整个分类（6 个策略，runonce/runnext 双模式自动对拍） +pytest

Williams 在 1985 年《Technical Analysis of Stocks & Commodities》的文章里给出的解法干脆利落——把三个周期**合成一个指标**，短周期权重最高： + +```python +params = dict( + stake=10, + p1=7, + p2=14, + p3=28, + oversold=30, + overbought=70, +) + +def __init__(self): + self.uo = bt.indicators.UltimateOscillator( + self.data, p1=self.p.p1, p2=self.p.p2, p3=self.p.p3 + ) + +def next(self): + self.bar_num += 1 + + if self.order: + return + + if not self.position: + # Entry: UO in oversold territory + if self.uo[0] < self.p.oversold: + self.order = self.buy(size=self.p.stake) + else: + # Exit: UO in overbought territory + if self.uo[0] > self.p.overbought: + self.order = self.close() +``` + +这是 [test_109_ultimate_oscillator_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/multi_indicator/test_109_ultimate_oscillator_strategy.py) 的全部交易逻辑——不到 20 行。注意 `bar_num` 断言是 **1229**，比同批策略少了 20-26 根：UO 需要 28 期买入压力（buying pressure）与真实波幅（true range）的完整历史，暖机期更长本身就是多周期合成的代价。 + +**结果是同批"教科书组"里最亮的一个**：终值 100,199.75，Sharpe 2.2256，最大回撤仅 6.37%。对比 SAR 版的 Sharpe 0.158、回撤 14.47%，多周期加权确实在降噪上做对了事情——当然，0.04% 的年化收益也提醒你：没有趋势过滤的超买超卖策略，赢的只是"体面"。 + +## 深读二：随机指标 KD——给交叉加一道"位置闸门" + +George Lane 在 1950 年代提出的随机指标，思想是"收盘价在近期区间中的位置"：贴着高点收盘是强，贴着低点收盘是弱。但裸的 K/D 交叉信号泛滥，教科书给出的修补是**只在超卖区买、只在超买区卖**。[test_103_stochastic_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/multi_indicator/test_103_stochastic_strategy.py) 忠实实现了这条规则： + +```python +def __init__(self): + self.stoch = bt.indicators.Stochastic( + self.data, + period=self.p.period, + period_dfast=self.p.period_dfast, + ) + self.crossover = bt.indicators.CrossOver(self.stoch.percK, self.stoch.percD) + +def next(self): + self.bar_num += 1 + + if self.order: + return + + if not self.position: + # K crosses above D and in oversold zone + if self.crossover[0] > 0 and self.stoch.percK[0] < self.p.oversold: + self.order = self.buy(size=self.p.stake) + else: + # K crosses below D and in overbought zone + if self.crossover[0] < 0 and self.stoch.percK[0] > self.p.overbought: + self.order = self.close() +``` + +参数是经典的 14/3，阈值 20/80。双闸门（交叉 + 位置）把 1,239 根 K 线里的交易压缩到只剩高质量区间：终值 100,219.02，Sharpe 0.692，最大回撤 8.50%。工程上值得学的是 `CrossOver` 这个封装——它把"上穿/下穿"的边界判断（昨天 ≤、今天 >）交给指标层，策略层只读一个正负号，可读性和出错率都优于手写比较。 + +## 深读三：抛物线 SAR——Wilder 的"一册宗师"遗产 + +J. Welles Wilder Jr. 1978 年的《New Concepts in Technical Trading Systems》大概是技术分析史上单本产出最高的书：RSI、ATR、ADX、抛物线 SAR 全部出自这里。SAR 的巧思在于**加速因子**——趋势每创新高，止损点就跟紧一步，像抛物线一样越收越快，直到把利润"逼"出来。[test_106_parabolic_sar_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/multi_indicator/test_106_parabolic_sar_strategy.py)： + +```python +params = dict( + stake=10, + af=0.02, + afmax=0.2, +) + +def __init__(self): + self.sar = bt.indicators.ParabolicSAR( + self.data, af=self.p.af, afmax=self.p.afmax + ) + self.crossover = bt.indicators.CrossOver(self.data.close, self.sar) + +def next(self): + self.bar_num += 1 + + if self.order: + return + + if not self.position: + if self.crossover[0] > 0: + self.order = self.buy(size=self.p.stake) + else: + if self.crossover[0] < 0: + self.order = self.close() +``` + +af 从 0.02 起步、封顶 0.2，是 Wilder 留下的原始参数。SAR 自带"止损即信号"的优雅，但它的软肋同样有名：震荡市里被反复打脸。回测也诚实——终值 100,044.47、Sharpe 0.158、最大回撤 14.47%，1,255 根 K 线下来几乎白忙。docstring 里那句提醒写得直白：SAR 在强趋势市场最有效，震荡市请配过滤器。 + +## 其余五席，快速点将 + +- **Williams %R**（`test_102`）：Larry Williams 1973 年的产物，与 KD

Σ(size)`。三个构件合起来，就是"摊成本、等回归、一把走"。回测窗口内它交出 1,591 笔交易、胜率 67.94%、盈利因子 2.57、终值 1,077,029.70（+7.70%）——但最大回撤 18.70%，且这还只是一段约三个月、未遇极端单边的行情。 + +## 深读二：MartGreg——给马丁格尔装上刹车 +

1,032,971.20（+3.30%），最大回撤 5.14%——低胜率高盈亏比，与 VR-SETKA-3 的高胜率重回撤正好是马丁光谱的两端。 + +## 深读三：Truly Random Robot——随机入场，为什么也能不亏？ + +这个分类里最"离经叛道"的资产是三个随机策略，以

线只评估一次"的门闩：双周期架构里没有它，一根 H4 会被 16 根 M15 重复消费，信号全乱。 + +## 深读二：Ergodic TVI——Blau 的多重平滑哲学 + +William Blau 在 1990 年代（《Momentum, Direction, and Divergence》）系统阐述了"Ergodic"一族指标：把任何原始量先做**双重指数平滑**滤掉噪声，再构造振荡器。TVI（Tick Volume Index）是他的思想用在 tick volume 上的样子。[test_0006_ergodic_ticks_volume_indicator.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/volume_system/test_0006_ergodic_ticks_volume_indicator.py) 的实现把整条流水线写得很清楚： + +```python +up_ticks = (vol + (frame['close'].astype(float) - frame['open'].astype(float)) / point) / 2.0 +down_ticks = vol - up_ticks + +ema_up = apply_ma(up_ticks, xlength1, xma_method) +ema_down = apply_ma(down_ticks, xlength1, xma_method) +dema_up = apply_ma(ema_up, xlength2, xma_method) +dema_down = apply_ma(ema_down, xlength2, xma_method) + +denom = (dema_up + dema_down).replace(0.0, np.nan) +tvi_calculate = 100.0 * (dema_up - dema_down) / denom +tvi = apply_ma(tvi_calculate, xlength3, xma_method) +ema_tvi = apply_ma(tvi, xlength4, xma_method) +ergodic_tvi = apply_ma(ema_tvi, xlength5, xma_method) +ergodic_signal = apply_ma(ergodic_tvi, xlength6, xma_method) +``` + +第一步最妙：阳线（close>open）的 tick 全记给多方，阴线记给空方，一分为二再各自双重平滑（`xlength1=xlength2=12`）——**tick volume 被升维成了"多空力量对比"**。TVI = 100×(多-空)/(多+空)，再经四道平滑得到 ergodic 线与信号线，交叉即交易。六个 `xlength` 参数对应流水线的六道工序，其中 `xlength3=1` 意味着 TVI 本身不再平滑——Blau 原文里这类旋钮的取舍，正是"平滑越深、信号越钝"这条曲线上的选点问题。H6 信号周期整段窗口只有 236 根 K 线、14 笔交易（8 胜 6 负），盈利因子 2.04、终值 1,005,203.90、最大回撤 0.34%。信号稀疏是高周期+多重平滑的必然代价，换来的是曲线的干净。 + +## 深读三：XPVT——把"量"乘进"价"的复利账本 + +PVT（Price-Volume Trend，价量趋势）是最古老的量价指标之一，思路朴素：价格上涨的 K 线把成交量加进账本，下跌则减去，形成一条累计线。[test_0007_xpvt.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/volume_system/test_0007_xpvt.py) 的 `compute_xpvt` 只有一个循环： + +```python +for i in range(1, len(out)): + prev_price = float(price.iloc[i - 1]) + curr_price = float(price.iloc[i]) + vol = float(volume.iloc[i]) + delta = 0.0 if prev_price == 0 else vol * (curr_price - prev_price) / prev_price + pvt.iloc[i] = pvt.iloc[i - 1] + delta +sign = smooth_series(pvt, xlength, xma_method) +``` + +每根 H4 K 线贡献 `volume × 价格变化率`——涨 1% 放量，比涨 5% 缩量对账本的推动更大，"量在价先"被写成了一个乘法。信号线是 PVT 的 5 期 EMA，上穿做多、下穿做空。本篇最漂亮的成绩单来自这里：49 笔交易、胜率 48.98%、盈利因子 3.26、终值 1,015,722.30（+1.57%）、最大回撤 0.19%。当然，三个月的黄金数据、零成本假设，都提示这只是基线而非福音——但它至少演示了量价合成线在方向过滤上的潜力。 + +## 其余四席，快速点将 + +- **VWMA

的假设是：**深夜盘口冷清，价格被压缩在箱体里，贴边即回归**。M1 数据执行、`resampledata` 重采出 H1 信号，只在 `open_hour`（配置为 0 点）前后的两小时窗口内评估信号： + +```python +hour = signal_dt.hour +if hour < int(self.p.open_hour) or hour >

diff_max): + return +``` + +三道闸门次第落下：先看时钟，再取**前 3 根 H1** 的高低点构成通道，最后要求通道宽度落在 100-400 点之间——太窄没有肉、太宽不是盘整。入场则精确到四分位： + +```python +if bid > lowest and bid <= lowest + diff / 4.0: + sl = lowest - diff / 3.0 + tp = ask + float(self.p.take_profit_pips) * pip if int(self.p.take_profit_pips) > 0 else None +``` + +价格落入通道**下四分位**做多、止损放在通道底下三分之一处（`lowest - diff/3`），上四分位对称做空；出场靠 50 点固定止盈加 15/5 点移动止损保护。仓位端也不含糊：`lots=0.1` 固定手数，或按 `risk=5.0%` 与 `margin_per_lot=1000` 从可用资金反推——把风险预算写进仓位公式，而不是拍脑袋。诚实的代价是信号极挑剔：2026-03-05 至 03-10 五天窗口、4,562 根 M1，只触发 **1 笔**空头交易——恰好盈利，终值 1,000,061.30。一箭双雕地示范了两件事：session 过滤+波动率闸门如何工作，以及样本量过小时任何胜率都毫无统计意义。 + +## 深读二：OpenTime——时钟即信号，别无他物 + +把时段交易删到只剩骨架，就是 [test_0003_opentime.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/time_session_system/test_0003_opentime.py)。它的 `next()` 里没有一个价格条件： + +```python +def next(self): + self.bar_num += 1 + dt = self.data.datetime.datetime(0) + if self.order is not None: + return + if bool(self.p.time_close) and dt.hour == int(self.p.close_hour) and dt.minute ==

float(self.data.close[0])) + return + if bool(self.p.use_sell): + self._arm('sell', float(self.data.close[0])) +``` + +每天 18:45 开一笔空单（`use_sell=True`，`stop_loss=0/take_profit=0`——纯裸仓），20:45 定时平掉；`_window_key` 这个日期+时刻的键值防止同一窗口重复开仓。实现细节还有一处值得圈点：数据加载时每根 K 线的时间戳整体前移 15 分钟、按**收盘时刻**标记，所以配置里的 18:45 指的是"这根 M15 收在 18:45"——时段策略移植中最常见的坑，就是源 EA 与回测引擎对时间戳语义理解不一致，差一根 K 线，全部开仓时刻跟着漂移。三个月窗口 67 笔交易、37 胜 30 负、胜率 55.2%、盈利因子 1.53、终值 1,002,199.70。每天两小时固定敞口的黄金空头能有此成绩，说明这段数据的傍晚漂移确实偏向下行——但请注意它同时是**一个自由度极少的假设检验**：没有指标、没有参数可调，"这个钟点该做空吗"的答案一目了然。`Exp_TimesDirection`（`test_0006`）与 `Open Close on Time`（`test_0007`）是它的近亲，区别只在"固定方向"与"首根越过时刻的 K 线"这类窗口判定的细节，三者摆在一起，恰好是一组隔离了窗口判定算法的对照实验。 + +## 深读三：21hour——两个窗口里的对夹突破 +

`notify_timer`（[test_62_timers.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/time_based/test_62_timers.py)）： + +```python +class TimerStrategy(bt.Strategy):

线。也就是说，**定时器从第一根 bar 就开始触发，而不用等指标就绪**。这个细节在实盘里意味着：预热期内该做的风控检查、数据同步，一天都不会漏。同一次回测的其余基线：终值 104,966.80、夏普 0.721、最大回撤 3.43%、9 笔完整交易。 + +## 深读二：重采样——日线攒成周线，历史一步到位 + +`resampledata` 解决的是"手上只有日线、策略想要周线"的问题。它把 5 根日 K 一次性聚合成 1 根周 K：开=周首开盘、高=周内最高、低=周内最低、收=周末收盘（[test_53_data_resample.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/time_based/test_53_data_resample.py)）：

1.079。数字本身平淡，真正有价值的是这 89 根周线被永久钉进了断言——任何人改动重采样的一行代码，这个测试都会立刻尖叫。这是"功能测试策略化"的典型样本：不 mock、不造数据，用一次真实回测守住一个框架特性。 + +## 深读三：数据回放——回到"那一根 K 线还没走完"的下午 + +重采样是把历史"压缩"，回放（Replay）则是把历史"重演"。同一份日线数据，`replaydata` 让策略在周线视角上运行，但**每来一根日线就推进一次**：你看到的是一根随交易日不断生长的周 K——周一收盘时它是"半根"，周五收盘才补全（[test_58_data_replay.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/time_based/test_58_data_replay.py)）： + +```python +# Use replay

108,263.90、夏普 1.179。为什么？因为回放中的指标每根日线都在重算，"周中"就能触发交叉——这正是回放存在的意义：**检验策略在没有未来数据、只有"半根 K 线"时的真实行为**。也正因如此，回放测试必须 `preload=False`、以事件驱动逐根喂数，它天然是对引擎慢路径的极限压测。同一套回放框架还跑了布林突破（419 根、2 笔）、EMA(12,26)（384 根、9

用 20 日均线把两只 ETF 的"相对强弱"变成一个可以比较的数字： + +```python +# If both ETFs are below moving averages, close all positions +if sz_close < self.sz_ma[0] and cy_close < self.cy_ma[0]: + if self.sz_pos > 0: +

sz_close) + self.buy(sz_data, size=lots) +``` + +三个设计细节值得抄：其一，比较的不是价格而是 `close/MA` 比率——动量被归一化，两只价格量级不同的 ETF 才可比；其二，"双双低于均线则全平"给了策略一个拒绝参赛的选项，轮动策略最怕的就是两边都是下跌趋势时被迫二选一；其三，仓位用 `int(0.95 * total_value / price)` 现金公式而不是固定手数，资金曲线才能复利。回测基线（2011-09-20 起、万分之二佣金、5 万本金）：2,600 根 bar、266 次买入、265 笔交易、年化 16.19%、最大回撤 32.03%、终值 235,146.29。收益不菲，但三成回撤提醒你：风格轮动从不温柔。 + +## 深读二：国债期货跨月套利——理想与现实的一课 +

定义价差通道，突破即开、回归即平。工程上真正值钱的是 `get_near_far_data()`：每根 bar 按持仓量排序找出当日最活跃的两个合约，一旦主力换月，自动平旧仓、按原方向开新仓——跨月套利的持仓寿命必然跨越主力切换日，没有移仓逻辑的套利回测都是玩具。然后是诚实的部分：T 品种 1,990 根 bar、86 笔交易跑完，夏普 **-2.24**、终值

溢价率升序排名，各占 50% 权重，合成分数取前 `hold_percent=20` 名等权买入；每根 bar 检查"当月最后一个交易日"触发调仓，过期订单自动撤销。注意排名用的是 `rank()` 而不是原始值——可转债的价格和溢价率量纲迥异，排名化是因子合成的第一课。基线同样诚实：1,300 根 bar、89 笔交易、夏普 -2.97、最大回撤

+实现（[test_37_bracket_order_strategy.py](https://github.com/cloudQuant/backtrader/blob/development/tests/functional/strategies/order_types/test_37_bracket_order_strategy.py)）在金叉出现时一次性构造三张单： +

self.sell(exectype=bt.Order.Limit, price=p3, + parent=o1, transmit=True) # 最后一张把三张一起发出 +``` + +关键是 `transmit` 与 `parent` 两个参数：前两张单 `transmit=False` 暂扣在手里，直到第三张 `transmit=True` 才整组提交；`parent=o1` 声明母子关系，引擎据此在主单成交后激活子单、在一张子单成交后撤销另一张。2005-2006 数据上共触发 8 笔完整交易（4 胜 4 负，胜率 50%），终值 99,875.56——测试以 `abs(final_value - 99875.56) < 0.01` 锁定基线。注意主单是限价单且 3 天有效：若价格不回落，整组过期作废，这在牛市里会错过行情，也是 bracket 的代价之一。 +

或加入最少交易数约束，往往选出完全不同的"最优"。另外注意 `bt.Cerebro(maxcpus=1)`：单线程保证可复现，生产中放开多核才是参数扫描的正确姿势。 + +## 深读二：信号策略——不写 Strategy 类的策略 + +同样的"价格站上均线做多"，可以不用 `next()`

Make product changes, packaging releases, and product-specific acceptance changes in their respective repositories; this repository only links to them from its README. +The cross-exchange arbitrage examples use `BtApiStore.getdata()` / `BtApiFeed` +with `orderbook_as_ticks=True` and `TimeFrame.Ticks`. Native `notify_orderbook` +callbacks drive `bt.Strategy.buy/sell` and `notify_order`; `BtApiBroker` routes +demo orders through public `BtApi` methods with `normalized=True`. +The SDK owns venue schemas, request mapping and optional execution-session state +(durable intents, unique client IDs, uncertain-order reconciliation and fees). +`bt_api_py.cross_venue` owns only provider-neutral, stateless typed execution +planning: quantity lattices, executable VWAP, cost accounting, funding schedule +validation and normalized orderbook evidence. It consumes SDK contracts and +does not own a client, account, order, pair state, alpha, or compensation policy. +The store holds `BtApi` directly and only maps framework orders, references and +native market-data objects; there is no second Backtrader trading client. +`examples/strategy_candidate_approval.py` binds the two example candidates' +manifest, offline receipt and source provenance. It is example admission policy, +not a Backtrader utility or SDK protocol. +OKX endpoint selection belongs to the SDK through +`api_region=global|eea|us|tr`: REST plus public/private/business WebSockets use +one atomic region/environment profile. Global/EEA/US support production and +demo; TR currently supports only production, so `tr+demo` fails before network +I/O. OKX 50119 proves that the selected credential/domain combination was +rejected; by itself it does not distinguish region, key, secret, passphrase, +expiry, or permission causes. +Funding is a typed SDK read model. `BtApiStore` refreshes it on a separate +single-concurrency read-only lane with request coalescing, TTL/schedule-boundary +expiry, and generation fencing; strategy callbacks only read the local cache. +This snapshot supports entry reserves and settlement-window risk. The SDK does +not yet expose a unified, pagination-complete, account-bound OKX/Binance funding +cashflow ledger, so a cycle crossing settlement cannot claim complete realized +net PnL. The production status is +`PRODUCTION_BLOCKED_ACTUAL_FUNDING_CASHFLOW_LEDGER`: venue-level single-page raw +income/bills parsers do not prove pagination coverage, identity, deduplication, +aggregation, settlement latency, or a complete empty result. Idle risk also +advances without a new bar through `notify_idle` polling. +The `exchange_kwargs` and `symbol_routes` +configuration supports multiple providers in a single broker. Amounts remain native units +(OKX contracts / Binance BTC); strategy sizing uses metadata multipliers. +The examples require independently verified dual-side/hedge mode and maintain +long/short legs separately; no net-position fallback is accepted. `shadow` uses +public production books with zero orders/fills/PnL, `paper-live` uses public books +with local hypothetical fills, and only `demo` can submit exchange orders. Demo +writes additionally require a strategy-specific, hash-bound approval receipt. +Both Iteration 21 frozen candidates failed their pre-OOS calibration cost screen, +so their `paper-live` simulated-fill and `demo` order paths remain prohibited; +read-only shadow and demo preflight remain available. Any new economic attempt +requires a new candidate ID, preregistration, and untouched holdout. +Credentials are kept in each example's ignored `.env`. Deterministic `replay` +reports are formula fixtures with zero orders/fills and no PnL; the native +Store/Feed/Cerebro/Broker path is tested separately. The second candidate is +classified as event-driven and remains `HFT FAIL/NOT_ADMITTED` until end-to-end +latency, queue and real-fill evidence exists. + ## Tests - `tests/functional/strategies/` holds 1,271 inlined regression tests across ~30 diff --git a/backtrader/brokers/bbroker.py b/backtrader/brokers/bbroker.py index 0f39f2f99..df623f47f 100644 --- a/backtrader/brokers/bbroker.py +++ b/backtrader/brokers/bbroker.py @@ -659,7 +659,7 @@ def _credit_key(self, data, position_side=None): def _validate_close_quantity(self, order, position): if not self._is_dual_side_mode(): return -

被视为待拆解的现有实现，不保留为 examples 级公共 +包，也不整体搬入 core。最终目标是活动代码零引用并删除目录。 + +### D-002：support 内容逐项判断 + +目录中的代码不能因已有测试就默认合理。元数据/数量量化、环境、readiness、单订单恢复等 +稳定能力进入 SDK/Core；策略参数和 pair 决策进入各自策略；fake/replay 进入 tests；重复入口、 +空高频子类和生成报告删除。 + +### D-003：两个现有策略都不作为已批准设计 + +012_1 保留“可执行基差均值回归”候选方向，但 z-score、完整成本、funding 和样本外准入必须 +重写。012_2 当前只是参数 profile，予以淘汰并重新做候选选择。 + +### D-004：SDK 维护统一交易接口 + +OKX/Binance/CTP/MT5 等 provider 的协议、环境、认证、schema、数量单位和执行会话仍由 +`bt_api_py` 维护。明确禁止 `_btapi_client.py`、`_btapi_crypto.py` 或等价第二客户端。 + +### D-005：Backtrader 只扩展现有适配层 + +Backtrader 使用现有 `BtApiStore`、`BtApiFeed`、`BtApiBroker`。Store 直接持有公共 `BtApi`， +Feed 映射行情，Broker 映射订单/账本；三者不解析 vendor schema。 + +### D-006：异步能力不能绕过安全会话 + +高频/事件驱动所需的非阻塞下单通过现有公共 `async_make_order/cancel/query` 的 typed normalized +扩展实现，并复用 journal、unique ID、environment、unknown 和 reconciliation。旧 async feed +方法不能成为 execution session 的旁路。 + +### D-007：只允许双向持仓 + +本目标明确要求 `dual_side`/hedge。任一账号为 net/one-way、unknown 或字段无法确认时，在写 +操作前 fail closed；不自动切换账户模式，不做净仓降级。 + +### D-008：暂不建立公共多腿套利引擎 + +单订单安全属于 SDK/Broker，pair alpha 与补偿策略属于示例。只有稳定语义和第二消费者证据 +出现后，才考虑把多腿协调器提升到 Core；当前允许两个策略各自有小型、可读状态机。 + +### D-009：高频名称由门禁决定 + +调短间隔、使用 tick 或继承中频类不足以称 HFT。012_2 只有在独立信号、非阻塞执行、事件 +连续性、本地延迟和机会寿命门通过时保留 highfreq 名称，否则改为 event-driven 并标记原 HFT +目标 `FAIL`；只有完成名称门所必需的外部数据不可得时才标 `BLOCKED`。 + +### D-010：默认研究 taker-taker，maker-taker 延期准入 + +taker-taker IOC 的状态和成本更容易在 demo 验证，作为默认安全基线；它仍可能因四笔成本而 +没有净机会。lead-lag 只有在特征、标签、阈值、方向敞口和 OOS 判据预注册且通过后才可替代 +基线。maker-taker 只有在队列位置、撤单延迟、fill probability、inventory 和 hedge markout +数据齐全时再进入实现。 + +### D-011：收益与工程验收分离 + +合成回放只验证机制，public shadow 不产生 fills，demo PnL 是观察性证据。平台工程子门禁可以 +PASS；但任一必交付策略在合格数据下被研究否决时，该策略不得提交 demo pair，原始总体目标 +为 `FAIL`。单次正收益不能推导实盘盈利。 + +### D-012：用户资产先保全后删除目录 + +support 当前含 ignored `.env`、reports/journal/lock。实施时只比较路径、权限、size、hash 并做 +字节备份；凭据不做语义解析、不展示。journal 由 SDK 迁移器按冻结 schema 解析，并在 fencing、 +原子 cutover、远程对账通过后才删除旧位置。 + +### D-013：新文档放在仓库既有迭代目录 + +BMad 默认 spec 输出在 `_bmad-output/specs`。本仓库 1–20 迭代均以 +`docs/_internal/opts/requirements/迭代N-*` 管理需求资产，因此本次把 `SPEC.md` 与 companion +放入迭代21目录，避免形成第二份规划真源；SPEC frontmatter 仍声明所有 companion。 + +### D-014：迭代20不列为已吸收 source + +迭代20仍是历史审计/实施记录，不能因新 SPEC 出现而失去下游价值，因此没有放入 +`SPEC.md::sources`。迭代21重新判定其结论，实施状态不沿用。 + +### D-015：每个账号只有一个 execution ledger owner + +SDK 对每个 `(provider, environment, account_id)` 维护唯一 physical ledger、canonical client order ID 与有效 writer +lease；strategy ID 只作分区。迁移必须冻结旧 writer、生成逐 intent claim manifest、隔离歧义、 +临时导入后原子发布并提升 fencing epoch。新 lock 重新创建，不能复制；新账本一旦产生写入， +回滚只能向前修复，不能重新启用旧 writer。 + +### D-016：队列、订单与补偿职责分开 + +SDK 提供 typed create/cancel/query/reduce-only、持久化和规范化 ID，不拥有 Backtrader 队列或 +pair flatten。Store 维护有界优先队列；Broker 创建 Backtrader order/close 语义并申请 SDK +canonical ID；策略决定双腿补偿方向和风险预算。 + +### D-017：成本只能由一个 Decimal oracle 计一次 + +L2 entry VWAP 已包含入场 spread/depth impact，不再重复扣减。统一 oracle 另计 entry fee、预计 +exit execution cost/fee、signed funding、latency reserve 和失败腿损失；策略、replay 与报告 +重算调用同一合同。 + +### D-018：HFT 因果证据强于计数守恒 + +两所接收时间必须来自同一 monotonic clock domain，或有可验证误差上界。ingress/coalesced/ +dropped 计数只作辅助；若无法证明 coalescing/drop 未改变策略可见因果序列，HFT 名称门失败。 + +### D-019：逐条追踪矩阵是唯一映射真源 + +新增 `追踪矩阵.md`，每个 FR/NFR 独占一行，直接关联设计章节、AC、TASK 和 Gate。验收文档不再 +用范围映射代替逐项可检验追踪。 + +### D-020：策略 demo 必须逐个批准 + +public shadow 和单 venue SDK smoke 只校准数据/执行；每个策略仍需独立 +`STRATEGY_APPROVED_FOR_DEMO`。收据绑定最终候选 manifest、源码、数据、配置、OOS、G4 与 +G5A 证据；无收据的策略自动 pair write 必须为零。 + +### D-021：第二策略降级为事件驱动候选，support 不作为运行时架构保留 + +独立对抗审查发现原“高频”实现没有端到端网络、交易所队列位置和真实成交延迟证据，且策略 +状态机仍有迟到成交、失败腿损益、远端空仓证明和账户累计止损缺口。因此目录和候选 ID 改为 +`012_2_event_driven_cross_exchange`，HFT Gate 固定为 `FAIL/NOT_ADMITTED`，只有新迭代产生完整 +端到端证据后才能重新命名。`examples/cross_exchange_arbitrage_support` 的通用协议、执行会话和 +框架适配能力分别迁入 `bt_api_py` 与既有 Store/Feed/Broker；策略假设留在各示例。用户资产经 +hash 验证迁移后删除 support 目录，不建立兼容转发包。 + +### D-022：公式 replay 不得冒充交易链路或收益证据 + +两个示例的确定性 replay 只检查成本公式、信号和拒绝分支，固定 `orders_submitted=0`、 +`fills=0`、PnL 指标为空，状态使用 `FORMULA_CHECK_PASS/FAIL`，证据等级为 +`R0_FORMULA_FIXTURE`。原 `profitable/loss` 名称仅作历史分支标签，不能形成盈利声明。原生 +Store/Feed/Cerebro/Broker 链路由独立集成回放和 public shadow 验收。 + +### D-023：训练成本屏先于 R1，两候选已否决 + +旧公开 L2 训练校准窗口的因果 executable-VWAP 屏在 149,387 个往返中没有任何一个 +能覆盖四笔、每笔 6 bps taker 费，最佳净结果仍为 -1.14246520 USDT。该屏属于 +`PRE_R1_CALIBRATION_TRAINING_SCREEN`，不是 OOS/R1。因此 012_1 和 +`012_2_event_driven_cross_exchange` 均为 `RESEARCH_REJECTED_AT_CALIBRATION_SCREEN`，预留 +holdout 保持 `NOT_CONSUMED`，`paper-live` 与 `demo` 写操作禁止。任何重新研究必须建立 +新 candidate ID、新预注册和未见数据。 + +### D-024：资金费快照与真实流水分层 + +SDK typed `FundingSnapshot` 和 Store 独立 refresh/TTL/generation-fence 通道只承担入场 reserve、结算 +窗口和 stale fail-closed。Binance 的周期必须来自 canonical symbol 唯一匹配的 `fundingInfo` 或 +公开 funding history 推导，不设 8h 默认，历史费率不冒充认证资金流水。虽然 venue +底层存在 Binance income/OKX bills，当前没有统一、分页完整且绑定账户身份的 +`FundingCashflow` primitive。所以执行摘要必须保持 `funding_evidence_status=unavailable` 和 +`signed_funding_cashflow=None`；跨结算 realized net 为 `INCOMPLETE`，该缺口是生产阻断。 +该状态统一记为 `PRODUCTION_BLOCKED_ACTUAL_FUNDING_CASHFLOW_LEDGER`；单页 raw parser 不具备 +统一 forwarding、分页覆盖、去重/高水位、currency 汇总、账户/策略归因、结算延迟和 +空结果证明，不能冒充 ledger 闭环。 + +### D-025：数据静默由 idle 通知推进，仍需完整网络证据 + +Backtrader 候选通过 `notify_idle` 让无 bar 的 TickBroker/MixBroker 执行安全风险轮询，避免 +在双 venue 行情同时静默时等待下一条事件。聚焦回归 2 passed 与更广的源码回归支持 +G2 工程 PASS；stop/restart、双 venue 中断、stale 到 wind-down 以及 public 网络现场证据仍归 G4。 + +### D-026：冻结研究否决 manifest 并闭合 G3 + +schema 3 candidate manifest 冻结为 `RESEARCH_REJECTED_DEMO_PROHIBITED`，总 SHA-256 为 +`1b654ca2c0335d9b8b2d50fea4eff62dddc572c9bbf57efd9b2aefd6afa95d0f`。两候选只允许 +`replay`/`shadow`，OOS 不消费，`paper-live`/`demo` 禁止。Backtrader 和 bt_api_py +wheel 分别以

**intent**：`bt_api_py` 统一处理 OKX/Binance 的模拟环境、认证、合约元数据、数量单位、订单请求、私有事件和不确定订单对账。 +- **success**：同步与非阻塞写操作都通过带类型、归一化、幂等和执行会话保护的公共 `BtApi` + 合约完成；账户持仓模式只经公共 `set_position_mode` 变更，且必须同时通过 provider + acknowledgement 与随后账户 readback；未知结果使缓存失效并锁住所有加密货币下单入口，直到 + fresh normalized read 收敛。持仓快照用 `Decimal` 保留精确零语义：query 只过滤 + `quantity_known=true` 且 `quantity_exact_zero=true` 的行，event 零量仍作为平仓 tombstone +

**success**：分别报告机制正确性、样本外研究结果、public shadow 机会质量、demo 执行正确性和 demo 观察性 PnL；任何单次正收益都不能单独通过发布门禁。 + +### CAP-9 安装与消费端一致性 + +- **intent**：改进后的 `bt_api_py` 和 Backtrader 可从源码构建、重新安装并由实际消费端运行。 +- **success**：记录源码 SHA、wheel SHA、安装位置和版本；本地源码测试与隔离安装测试均通过，且安装环境无法导入被禁止的第二客户端模块。 + +### CAP-10 支持目录退役 + +- **intent**：对支持目录逐项判定保留、重写、提升到公共 API、迁移到测试夹具或删除，不能机械搬迁整包代码。 +- **success**：每项能力已有新归属和测试后才原子删除目录；删除后两个示例、核心回归和安装态验收全部通过。 + +## Constraints + +- 候选源码可继续本地、隔离安装和只读网络验证；当前研究状态禁止 + `paper-live` 和 `demo` 订单写操作。 +- 交易范围限定 OKX 与 Binance 的 USDT

mode；不得在启动流程中自动变更账户， + 也不得维护 OKX/Binance 私有变更字段。需变更时由独立管理步骤显式调用 `BtApi.set_position_mode`， + 随后再用只读 preflight 确认。 +- 通用能力只有在存在稳定公共语义和至少两个合理消费者时才提升到框架；策略假设、阈值和配对状态保留在示例策略中。 +- 同一 demo 账户只能有一个权威 execution ledger 和一个有效 writer lease；策略 ID 只作分区， + 不能把旧共享 unknown intent 拆给多个恢复者。 +- 所有 Python 命令使用 `/Users/yunjinqi/opt/anaconda3/bin/conda run -n base python ...` 或该环境中的模块入口。 +- 本轮不读取、打印、提交或复制真实凭据；后续迁移只允许不解析内容的字节级备份/复制与 + hash 校验，示例源码只提交变量名和占位模板。 + +## Non-goals + +- 不保证模拟或实盘盈利，也不把 demo 成交质量等同于真实队列位置、流动性和延迟。 +- 不在本迭代接入更多交易所、现货、交割合约、CTP 或 MT5 套利策略。 +- 不构建独立交易终端、第二套 SDK 客户端或 examples 级公共框架。 +- 不以 maker 排队模型作为首版默认执行；maker-taker 只有在队列、撤单延迟和成交概率数据充分时另行准入。 +- 不要求跨交易所原子成交；系统必须显式管理腿风险和补偿。 +- 不因现有文件或类名存在就承诺保留其内容、参数或算法。 + +## Success signal + +迭代只有在需求追踪矩阵中的所有 P0/P1 自动化门禁、源码态与安装态门禁、两套独立策略语义门禁、两套策略各自的 `STRATEGY_APPROVED_FOR_DEMO`、两家模拟账户的只读预检和最小订单生命周期门禁均取得新鲜证据后，才可标记 `PASS`。外部账号、权限、合格数据或交易所环境不可用记为 `BLOCKED`；未执行记为 `NOT_RUN`；经济假设被数据否决记为 `RESEARCH_REJECTED`，对应策略与总体目标不得 PASS。当前两个必交付候选均在训练成本筛选被否决，所以总体策略目标已为 `FAIL`；后续工程或安装门禁即使通过也不能覆盖该结论。收益研究与工程子门禁分别报告，也不能把任何工程 `PASS` 描述为可实盘盈利。 + +## Assumptions + +- 首选研究标的是两家交易所共同提供、合约规则可精确对齐且深度充足的 USDT 本位永续合约；最终标的由实施时的元数据与流动性审计确定。 +- 第一版执行研究以 taker-taker IOC 为基线，原因是成交状态更容易验证；该冻结候选已被训练成本屏否决，不再进入 OOS 或 demo。 +- 候选路径、runner、strategy、config、qualification 和 economic screen 已由 schema 3 manifest + 冻结；只有绑定这些 hash 的收据可以改变对应 Gate。 + +## Open questions + +- 两个模拟账号的实际费率档位、资金费口径、最小下单量、杠杆和可交易标的需要在不泄露凭据的预检中重新读取。 +- 012_2 的 taker-taker 基线已在训练校准成本屏中被否决，HFT 命名已取消；新假设必须使用新 candidate ID、新预注册和未见 holdout。 +- 是否值得建立通用多腿订单协调器需要先找到第二个非 012

`examples/012_2_event_driven_cross_exchange`。 + +两个策略已分开实现统计/事件信号和腿状态，但“策略可实现模拟盈利”的必交付 +目标被数据否决。训练校准窗口的 149,387 个因果往返在四笔、每笔 6 bps taker +费后正样本为 0，最佳结果仍为 -1.14246520 USDT，而且还未扣不利 funding、网络 +延迟、失败腿损失与模型误差。这是对候选有利的上界否决。 + +因此，两候选均为 `RESEARCH_REJECTED_AT_CALIBRATION_SCREEN`，证据级别是 +`PRE_R1_CALIBRATION_TRAINING_SCREEN`。OOS/holdout 保持 +`NOT_CONSUMED_TRAINING_SCREEN_FAILED`，不存在 R1 收益通过或模拟账户准入。

`native_to_base_quantity(native_qty)`； +- `quantize_quantity(qty, rounding="floor")`； +- `validate_order_quantity(qty, price=None)`。 + +要求： + +- OKX contracts 与 Binance base quantity

`FeeSchedule`：account/venue/symbol、maker/taker、币种、来源、freshness； +- `FundingSnapshot`：当前费率、下一结算时间、结算周期、来源、freshness； +- `TradingReadiness`：environment、can_trade、position_mode、instrument status、max size、 + leverage/margin mode、阻断原因。 + +Fee 不可用时策略使用显式配置的保守上界，但研究结果标为 `COST_ASSUMPTION`；不能把静默 +fallback 当实际费率。资金费读路已实现为 SDK typed `FundingSnapshot` → Store 独立单并发 +刷新工作线程 → 带 TTL/下次结算边界的本地缓存 → 策略 venue/symbol 绑定校验。刷新 +不占用 order/cancel/reconcile 优先队列；缺失、过期、时区/周期非法或 identity 错配均 +fail closed。 + +这个读模型只能用于入场前资金费 reserve 和结算窗口风控。跨越结算时点后的 +realized net 必须由 OKX/Binance 认证资金费账单/私有流水聚合得到；当前 SDK 仅显式

normalized=True)` 已包含类型、环境和执行会话 +语义；现有 `async_make_order` 是旧 feed 异步路径，并在 execution session 开启时拒绝。因此 +本迭代扩展现有公共异步名称，而不是再造客户端： + +```python +await api.async_make_order(exchange_name, order_request, normalized=True) +await api.async_cancel_order(exchange_name, cancel_request, normalized=True) +await api.async_query_order(exchange_name, query_request, normalized=True) +``` + +设计要求： + +1. `normalized=True` 强制类型请求；返回字段和同步 normalized 路径一致。 +2. `_ExecutionSession` 增加 async invoke，但复用同一 ID 预留、写前 journal、环境门禁、 + unknown 分类、私有事件合并和恢复状态；绝不能绕过同步路径的安全层。 +3. 后端有原生 async 时直接 await；只有同步后端时由受控 worker 执行，不能堵塞调用者事件 + 循环。 +4. SDK 不实现 Backtrader placement queue 或 `flatten` 操作；它只提供 typed create/cancel/query、 + `reduce_only` 和单订单安全门。队列优先级由 Store/Broker 层负责。 +5.

验证；候选被研究否决后，`paper-live` 与 `demo` 写操作禁止 + +## 1. 背景与问题定义 + +用户要在 OKX 与 Binance 模拟环境中，以 USDT 本位永续合约运行两个跨所套利示例：一个 +中低频，一个高频。底层统一接口必须由 `bt_api_py` 维护，Backtrader 通过现有 +`BtApiStore`、`BtApiFeed`、`BtApiBroker` 使用这些能力，未来才可能谨慎迁移到实盘。 + +本迭代开始时，主要能力被放在 `examples/cross_exchange_arbitrage_support/`，形成了以下 +问题；该目录现已在用户资产字节级保全、能力归属和源码引用清零后移除： + +1. 012_1、012_2 的 `run.py` 和 `strategy.py` 主要是共享目录的薄包装，示例自身不能说明 + 策略逻辑、装配和风险边界。 +2. 共享目录包含配置、回放客户端、网络 runner、账户预检、风险状态机、报告和两套策略， + 已成为未经正式定义的应用框架；单元测试还直接依赖其内部对象。该目录当前未被 Git + 跟踪，而已跟踪的两个示例直接导入它，fresh checkout/候选提交存在确定的 `ImportError` + 风险。 +3. 012_2 的高频类只继承中频类并修改 `mode`/参数，没有独立信号或执行热路径。 +4. `SpreadZScore` 和 `entry_zscore` 只用于观测/报告，没有进入开平仓判定。 +5. 合成盈利回放预先构造大幅价差并忽略真实队列、延迟和冲击，只能验证状态机。 +6. 同步网络下单发生在策略事件路径时，会阻塞行情处理；把评估间隔改到 50ms 或 100ms + 不能使其成为高频系统。 +7. 通用能力、交易所能力、Backtrader 映射和策略专属逻辑的归属混杂，容易再次产生 + `_btapi_client.py` 或 `_btapi_crypto.py` 这类平行实现。 +8. 当前中频配置允许约 1800 秒持仓，而网络 runner 最长只允许运行约 600 秒并禁止跨资金费 + 结算，默认流程无法验证自己的持仓期与资金费假设。 + +因此本迭代不假定现有目录、类或策略值得保留。所有内容按证据分类为 `KEEP`、`REWRITE`、 +`PROMOTE`、`MOVE_TO_TESTS`、`DROP` 或 `NEEDS_EVIDENCE`。 + +## 2. 目标与使用场景 + +### 2.1 业务目标 + +-

conversion, grill-with-docs requirement analysis, opsx proposal workflow). ---- - -# 标准开发流程 - -## 概述 -JoyinCode 推荐采用“转换 → 拷问 → 提案 → 实施 → 归档”五步法。每一步必须依次执行，不可跳跃。 - -## 开发流程 - -### 步骤 1：需求文档转换（markitdown） -**目的**：将非 Markdown 格式的需求文档（如 Word、PDF）转为纯文本 Markdown，便于后续 AI 读取和拷问 - -**操作**： -1. 在对话中上传需求文档（.docx/.pdf 等） -2. 输入指令：`转为md`（或 `markitdown`） -3. 工具自动将文档内容提取为 Markdown 格式，并保存至 `docs/` 目录下，文件名与原始文档相同（后缀改为 .md） - -**示例**：选择需求word文档并输入 `转为md` - -> 📌 转换后的文档仅包含文字内容，图片、表格等复杂元素会被忽略或转为文字描述。若原文档包含关键图表，建议在拷问步骤中人工补充说明 - -### 步骤 2：需求拷问（grill-with-docs） -**目的**：对转换后的需求 Markdown 进行多轮问答，挖掘隐含需求、识别歧义、补全缺失细节，确保需求可执行 - -**操作**： -1. 在对话中选中刚生成的 .md 文件（或指定文件路径） -2. 输入指令：`/grill-with-docs 开发[功能名称]`（例如 `/grill-with-docs 开发用户登录模块`） -3. 系统会基于需求内容主动提问（如异常流程、边界条件、性能指标等），开发者逐一回答 -4. 拷问完成后，需求文档中所有模糊点应已澄清，并获得一份“拷问纪要” - -**示例**：选择需求 md 文档，输入 `/grill-with-docs 开发xxx` - -> ⚠️ 关键约束：OpenSpec 无法直接引用拷问过程的成果物，因此 拷问与下一步“发起提案”必须在同一个对话会话中连续进行，以共享上下文。若中途切换对话，拷问成果将丢失 - -### 步骤 3：发起提案（opsx propose） -**目的**：基于拷问后的需求，生成 OpenSpec 规格变更提案，包括影响范围、变更清单、验收标准等 - -**操作**： -1. 确保当前对话仍包含步骤 2 的拷问上下文 -2. 选中需求 .md 文件（或直接引用） -3. 输入指令：`/opsx 发起提案` -4. OpenSpec 自动分析需求与现有规格，生成提案文档（位于 openspec/changes//） -5. 开发者务必人工审核生成的提案内容，确认： - - 变更描述准确 - - 影响模块覆盖完整 - - 验收条件可测 - - 与拷问结论一致 - -**示例**：选择需求 md 文档，输入 `/opsx 发起提案` - -> 💡 若提案不完善，可多次调用 `/opsx propose` 进行调整，或手动编辑提案文件后重新运行 - -### 步骤 4：实施提案（opsx apply） -**目的**：按照已审核通过的提案进行代码开发和测试 - -**操作**： -1. 确认提案内容已完全符合开发要求（可再次运行拷问或与团队评审） -2. 输入指令：`/opsx 实施提案`（或 `/opsx apply`） -3. OpenSpec 会根据提案生成任务清单，并引导开发者按任务顺序编码 -4. 完成所有任务后，运行项目的单元测试、集成测试，确保验收条件全部通过 - -**示例**：输入 `/opsx 实施提案` - -### 步骤 5：归档提案（opsx archive） -**目的**：开发完成且测试通过后，将提案状态标记为“已完成”，并归档规格变更，更新主规格文档 - -**操作**： -1. 确认代码已合并至目标分支，且所有测试通过 -2. 输入指令：`/opsx 归档提案`（或 `/opsx archive`） -3. OpenSpec 会将变更合并到主规格中，并将提案目录移至 `openspec/changes/archive/` - -**示例**：输入 `/opsx 归档提案` - ---- - -# 常见问题与最佳实践 - -**最佳实践**： - -| 问题 | 解决方案 | -|---|---| -| 拷问后忘记在同一会话中发起提案 | 若已关闭对话，从 `CONTEXT.md` 和 `docs/adr/*.md` 中获取历史拷问结果 | -| 提案生成后想修改内容 | 可直接编辑 `openspec/changes//proposal.md`，然后重新运行 `/opsx propose` 更新 | -| 需求文档包含大量图片 | 在拷问时用文字描述图片内容，或上传补充说明文档 | -| 开发中需要新增需求 | 回到步骤 2 重新拷问，再发起新的提案（而非修改当前提案） | -| OpenSpec 命令报错 | 检查 Node.js 版本，重新安装 `@fission-ai/openspec` 修复配置 | - -## 环境与项目结构 - -详见 [references/environment.md](references/environment.md)。 diff --git a/.joyincode/skills/devwiki/references/environment.md b/.joyincode/skills/devwiki/references/environment.md deleted file mode 100644 index 44662fcde..000000000 --- a/.joyincode/skills/devwiki/references/environment.md +++ /dev/null @@ -1,24 +0,0 @@ -# 环境配置参考 - -## 本地环境要求 - -- **Node.js**：版本 >= 20.19.0 -- **OpenSpec CLI**（用于提案管理） - -## OpenSpec 安装 - -```bash -npm install -g @fission-ai/openspec@latest -``` - -安装后可通过技能 `opsx` 初始化 OpenSpec。 - -## 项目目录结构 - -``` -/ -├── docs/ # 存放所有需求文档（原始 Word/PDF 及转换后的 .md） -├── openspec/ # OpenSpec 自动生成的规格文档（勿手动修改） -├── 前端项目代码/ # 前端项目代码（具体框架不限） -└── 后端项目代码/ # 后端项目代码（具体框架不限） -``` diff --git a/.joyincode/skills/jccb/SKILL.md b/.joyincode/skills/jccb/SKILL.md new file mode 100644 index 000000000..fe50b184b --- /dev/null +++ b/.joyincode/skills/jccb/SKILL.md @@ -0,0 +1,154 @@ +--- +name: jccb +description: 项目框架代码库 RAG 与 grep 搜索技能。需要查看后端框架源码时触发 +--- + +# 技能说明 + +本技能通过 MCP 端点连接 jccb MCP 服务，提供框架代码的语义搜索、文件读取和 grep 内容搜索能力，供 AI 编码助手需要查看框架源码时使用（了解框架功能、排查框架问题） + +## 运行方式 + +使用 Python 脚本 `scripts/jccb.py` 调用 MCP 端点，配置集中在脚本同目录 `jccb.config.json`（endpoint / timeout / projectId） + +```bash +python scripts/jccb.py # 列出可用工具 +python scripts/jccb.py method ping # 连通性检查 +``` + +> 工作目录：脚本路径相对 `.joyincode/skills/jccb/` 所在的项目根目录，或使用脚本绝对路径执行。 + +## 工具说明 + +所有工具都需要 `projectId` 参数（取配置文件中的值，也可用命令行 `projectId=xxx` 覆盖，优先），用于定位框架代码仓库。 + +### 1.

0.002 BTC 成功开仓并平仓。官方错误表未检索到 50123 细分原因， +当前归因为"品种授权"，但未排除数量/单位问题。 + +**根因分析**（三层嫌疑，需逐层验证）： + +1. **公共规则归一化层**。策略的 VenueRules 来自 `store.get_symbol_info()` 的 + `multiplier/lot_size/min_size`（`run_network.py:67-86`），随后： + - 公共步长 `common_step` = LCM(OKX `multiplier×lot_size`, Binance `qty_step×contract_size`) + （`examples/.../common.py:118-125`）； + - 意图数量 `floor_quantity(quantity, common_step)`（`common.py:316`）； + - 下单数量 `canonical_quantity(rule.to_native(quantity), rule.qty_step)` + （`strategies.py:347-349`，base BTC → 张）。 + 若 SDK 返回的 `lot_size`（如 0.01 张）与 OKX 下单接口实际校验的 `lotSz`（BTC-USDT-SWAP 主网 + 为 1 张）不一致，策略会发出 0.2 张这类非法数量 → 拒单。`VALIDATION.md` 的 + `session-sdk-public-contract-rules.jsonl` 声称"实时公共规则与 SDK 标准字段逐项一致"， + 但该核对是 SDK 字段↔SDK 归一化的自洽，**未对照 OKX 原始 `ctVal/lotSz/minSz`**。 +2. **SDK 换算层**。见 P0-2：`size_in_contracts=False` 路径上 KeyError 静默吞掉后 base 数量 + 会被原样当作张数发出。当前 backtrader 路径默认 `quantity_unit="native"` + （`stores/btapistore.py:3887-3891`）→ mapper 置 `size_in_contracts=True` 绕过； + 但"native = 调用方已完成换算"是**隐式契约**，无断言、无文档。 +3. **数量过小静默归零**。若真实规则下 `common_step=0.01 BTC`（OKX 1 张步长），默认 + `--quantity 0.002` 会 floor 成 0 → `valid_quantity` 拒绝 → `reject("no_executable_net_edge")` + （`common.py:282-286, 316-340`）——策略静默不开仓，且与"无价差"不可区分。而实测中策略 + 确实发出了 OKX 请求，说明当时 `common_step ≤ 0.002`（即 SDK 返回的 lot_size 更细）， + 反过来印证第 1 层嫌疑。 + +**影响**：OKX 腿无法成交 = 套利链路整体不可用；或策略发非法数量反复被拒。 +`--execution-smoke` 强制 `quantity ≤ 0.002 BTC`（`strategies.py:72-75`）——若 OKX 最小可交易 +单位是 0.01 BTC，**smoke 验收在真实规则下永远无法完成**。 + +**修复建议**： +- [示例/backtrader] 增加启动时数量换算自检：打印每个 venue 的 + `multiplier/lot_size/min_size` 原始返回 + 计算出的 `common_step` + `trade_quantity` 换算 + 后的张数，与 OKX 公共接口原始 `ctVal/lotSz/minSz` 对照断言，不一致即 BLOCKED。 +- [示例] 拒单原因细分：数量被 floor 为 0 时记 `rejections["quantity_below_lattice"]`， + 与 `no_executable_net_edge` 区分；报告输出 `intent_quantity_floor` 字段。 +- [示例] `--quantity` 默认值改为按合约规则动态取"两个 venue 的最大最小可交易量"，或在 + 参数校验时直接拒绝低于该值的数量；`execution_smoke` 的 0.002 上限同样动态化。 +- [bt_api_py] 归一化 `get_symbol_info` 时保留/透出原始 `lotSz/minSz/ctVal` 字段供上层核对 + （若已透出，则在示例自检中使用）。 +- [测试] `tests/unit/test_cross_exchange_arbitrage.py:224` 目前用 + `VenueRules(contract_size=0.01, qty_step=0.2)` 等合成规则；补充一组以 OKX 真实规则 + （ctVal=0.01、lotSz=1、minSz=1）为基准的用例，断言 0.002 BTC 输入要么被 floor 成 0、 + 要么被前置校验拒绝，且报告原因可区分。 + +**验收标准**：demo 环境 OKX 腿出现至少一次真实成交（或在授权修复后），报告 +`execution_coverage` 含 OKX open/close；单元测试覆盖真实规则的 floor/拒绝路径。 + +### P0-2 SDK：OKX SWAP 数量换算 KeyError 被吞，base 数量静默当作张数（bt_api_py） + +**证据**：bt_api_okx `trade_mixin.py:53-57`——`size_in_contracts` 与 `skip_size_conversion` +均为假时执行 `vol = round(vol * self._params.symbol_leverage_dict[symbol])`；而 +`symbol_leverage_dict` 只含 5 个**现货**键（`okx_exchange_data.py:59-66`），SWAP 符号触发 +KeyError → 仅 warning → 数量不换算直接发出。绕过路径依赖上层传对 +`size_in_contracts`（mapper 仅在 `quantity_unit ∈ {contracts, native}` 时置真， +`_venue_mappers/okx.py:31`）。 + +**影响**：当前 backtrader 集成路径因 store 默认 `"native"`（btapistore.py:3887-3891）侥幸 +绕过；任何 `quantity_unit="base"`（或缺省且 metadata 为空以外的路径）都会发出 100 倍偏差的 +数量。这是 P0-1 的第 2 层嫌疑，也是 SDK 独立缺陷。 + +**修复建议（bt_api_py）**： +- SWAP 合约按 `get_symbol_info` 的 `ctVal` 完成换算，或在缺少换算表时**抛异常而非 warning**； +- `symbol_leverage_dict` 命名误导（实为 1/ctVal 换算表），重命名并补充 SWAP 条目或删除； +- 增加"OKX SWAP + quantity_unit=base"的映射测试（现有 + `bt_api_contract/test_okx_order_mapping.py` 无 SWAP/dual_side/IOC 用例）。 + +**验收标准**：`quantity_unit=base` 下 BTC-USDT-SWAP 请求的 `sz` 等于 base/ctVal；无换算数据时 +抛出明确异常。 + +### P1-1 "高频"策略与中频代码路径完全相同 + 事件循环内同步

+**修复建议**： +- [bt_api_py] orderbook 归一化透出 `sequence`（Binance `u`、OKX 用 checksum 或序号）； +- [backtrader] `OrderBookSnapshot` 增加 `sequence` 可选字段；`_drain_sdk_events` 透传； + store 维护 `books_dropped` 计数（可用

P1-3 WSS 账户/持仓推送被 store 丢弃，余额/持仓纯 REST 轮询（backtrader + bt_api_py） + +**证据**：SDK 已把账户 WSS 推送归一为 `kind="account"/"position"` 事件（bt_api_py +`_normalization.py:982-996`），但 `BtApiStore._drain_sdk_events`

`consistency` 参数但忽略。 + +**影响**：成交后至下次 REST 刷新前（秒级）`getcash/getvalue` 为旧值；策略 +`opening_intent` 的可用保证金约束基于旧现金，可能过量开仓（有 `margin_fraction=0.5` 缓冲）。 + +**修复建议**：[backtrader] `_drain_sdk_events` 处理 `account/position` 事件更新 +`_venue_balance_cache`/持仓缓存（注意与 `position_sync_policy="startup"` 的记账权威边界： +推送只刷新余额与"对账提示"，不直接改本地腿仓，避免破坏 1-4/1-5 的记账语义）； +`get_balance` 在收到推送后标记缓存新鲜。 + +**验收标准**：集成测试注入 account

策略回调。`execution_basis=none`、`hypothetical_fills=false`、 +`pnl_fields_emitted=false`；`trend`/`reverse` 场景也保持零订单。 + +网络运行前，把 `.env.example` 复制为本目录 `.env` 并填写本地值。runner 优先读取 +`CTP_*`，也兼容 `SIMNOW_*` 和仓库已有的小写 `simnow_*`；任何日志、报告和 manifest +都不得保存原值，只保存 `acct_`。第一套第一组是默认 +profile：TD `180.168.146.187:10201`、MD `180.168.146.187:10211`；第一套第二组和 +7x24 第二套也只能以 config 中完整成对的 profile 使用。显式覆盖必须同时提供 MD/TD，

1 手平仓。恢复权限是一次性 +token；任何发送失败、超时、身份变化或新私有回报都会撤销权限并恢复只读状态。 + +自动恢复不能证明完成时，Store 和账户级 writer lock 会继续存活，进程每 250ms 轮询一次 +只读恢复计划，并持续写入 `execution_recovery.json`。此阶段不会自动重复下单。只有 SDK 返回 +两轮独立、同代际的 FLAT 查询并成功消费 completion token，进程才以退出码 0 和 +`RECOVERY_STOPPED_FLAT` 结束。 + +需要由人工系统接管时，在本次输出目录写入 `operator_takeover.json`。文件必须恰好包含以下 +字段：`schema_version`、`action`、`approval_key_id`、`run_id`、 +`account_fingerprint`、`trading_day`、`instrument`、 +`recovery_evidence_sha256`、`acknowledged_at_utc`、`signature_hmac_sha256`。 +其中 schema 为 `backtrader.ctp.operator-takeover.v1`，action 为 +`takeover_execution_recovery`；身份字段必须匹配当前 run，证据 hash 必须匹配当前恢复计划。 +签名使用 `ITER22_APPROVAL_HMAC_KEY` 对除签名字段外的排序紧凑 JSON 做 HMAC-SHA256， +`approval_key_id` 必须等于 `ITER22_APPROVAL_KEY_ID`。验证通过只证明责任已交接，不证明 +账户归零或 G4 通过；进程以退出码 3 和 `RECOVERY_OPERATOR_TAKEOVER` 结束。 + +SIGINT/SIGTERM 也会先落盘最终恢复证据，再以退出码 3 和 +`RECOVERY_FORCED_TERMINATION` 结束。其它 `MANUAL_INTERVENTION` 同样返回 3，便于 CI 和 +运维系统把它识别为需要处理的非成功终态。 + +## 合约冻结与当前阻断 + +CTP `InstrumentField` 提供 `ExpireDate`，但不提供“剩余交易日”或上一完整 TradingDay +全市场 OI/Volume 排名。runner 不用自然日、工作日或当日累计行情代替这些证据。 +默认 `contract_selection.mode=auto` 因此会明确返回 +`BLOCKED_CTP_TRADING_CALENDAR` 或 +`BLOCKED_CTP_PRIOR_DAY_RANKING_EVIDENCE`，不会静默降级到手工月份。 + +要运行 shadow/G3，可准备一个冻结的 CZCE 交易日历。示例 schema： + +```json +{ + "schema_version":

"20260914"] +} +``` + +计算文件 SHA-256： + +```bash +/Users/yunjinqi/opt/anaconda3/bin/conda run -n base python -c \ + 'import hashlib,pathlib; p=pathlib.Path("/absolute/path/czce-calendar.json"); print(hashlib.sha256(p.read_bytes()).hexdigest())' +``` + +把 artifact 的相对或绝对路径及 hash 写入 `trading_calendar`，然后显式冻结月份： + +```yaml +instrument: SA701 +contract_selection: + mode: manual + product: SA + exchange: CZCE + minimum_trading_days_to_expiry: 5 + manual_reviewed_at: "2026-09-09T08:00:00+08:00" + manual_source: "operator-review-ticket-123" + manual_trading_days_to_expiry: 42 + manual_trading_days_source: "authoritative-source-and-version" + manual_trading_days_evidence_sha256: "" +trading_calendar: + artifact: "/absolute/path/czce-calendar.json" + sha256: "" +``` + +`manual_trading_days_to_expiry` 不是自由声明值。runner 从 CTP session `TradingDay` 开始， +用冻结日历数到该 `InstrumentField.ExpireDate`，并要求计算值、source、hash 与 config 完全 +一致。夜盘仍以 CTP TradingDay 为基准。Stage A 还要求完整 account/positions/orders/ +trades/instruments 查询，验证实际月份存在、`IsTrading`、`ExpireDate`、PriceTick=1、 +VolumeMultiple=20、最小手数=1；Stage B 再为冻结月份查询费用和保证金，并拒绝两个阶段 +之间任何账户、TradingDay、generation 或 metadata 变化。涨跌停只接受本 generation、 +本 TradingDay 的有效 `ctp.quote.v2` 行情，不能从静态合约或费用查询伪造。 + +## 冻结策略规则 + +- 一档行情必须声明 `schema_version=ctp.quote.v2`、`volume_semantics=delta`，并有完整 + wall event time、monotonic receive time、ingest sequence、TradingDay、ActionDay、 + generation、累计/增量成交量、上下限价和质量字段。 +- `I=(bid_size-ask_size)/(bid_size+ask_size)`，按真实持续时间计算 5 秒均值； + `micro=(ask*bid_size+bid*ask_size)/(bid_size+ask_size)`；OFI 使用相邻一档价格/数量 + 变化并在 5 秒求和；15 秒 mid momentum、60 秒价格波动和 1 秒收益均要求有效锚点。 +- 分钟层使用 Backtrader 原生 EMA(5)、EMA(20)、ATR(14)。1/3/5 分钟收益只用连续、 + 已完成、已到 `available_at` 的 bar；量比只用同 TradingDay 的前 20 个有效分钟。 +- 融合权重固定在 `config.yaml`。费用来自账户级完整 commission query；保证金来自 + 独立完整 margin query。预期波动必须严格大于 spread、双边滑点、开平费用和 + 1 tick buffer 的总和。 +- 开仓前预热 60 个合格完成 bar 和 60 秒合格盘口；同一 bar 需方向连续 2 秒且至少 + 3 个新 quote，任何不合格 quote、bar 切换或方向变化都会重置。 +- 仅限价 GFD、1 手、最大潜在敞口 1 手。3 秒未终态请求撤单，撤单 5 秒无终态进入 + `UNKNOWN`；普通退出不得早于保守 fill 上界后 60 秒，强制退出不得晚于 fill 下界后 + 900 秒。idle 回调继续推进超时、session end、断流退出和对账。 +- 日损为 `min(500 CNY, starting_equity*0.5%)`。风险文件把累计 gross 和 fee 分开， + admission 只计算 `gross-fee+unrealized`；净亏损连续 3 笔停止开仓。新 TradingDay 必须 + 绑定完整对账后才能建立新基线。 +- 风险文件写失败后永久停止开仓。已有仓位或开仓挂单仍可依赖 SDK durable intent， + 以进程内、按动作一次的 emergency token 尝试减仓/撤单；残余 token 和失败原因写入 + report，不能把本地文件失败当作放弃退出的理由。 + +## 证据与验收 + +每次运行目录固定包含 `manifest.json`、`preflight.json`、 +`contract_selection.json`、`reconciliation.json`、`daily_report.json`、 +`retention.json`，并按实际事件 +产生 `quotes/bars/signals/orders/trades/risk_events.jsonl`。行情、bar、signal 走有界 +异步队列；订单、成交、风控同步 fsync。队列满、磁盘低水位、写失败、轮转超限或 +有界 drain 失败都会锁存 `FAIL_EVIDENCE_INCOMPLETE`，停止开仓且不会被最终状态覆盖。 +manifest 绑定本示例源码、fixture/config、实际导入的 backtrader/bt_api_py 路径、版本和 +文件 hash；网络模式还绑定 bt_api_ctp package/native 文件身份。证据只保留账户指纹。 + +默认报告根目录按 manifest 中冻结的 TradingDay 管理。每个网络运行只接受一个 +TradingDay，因此该运行内的 `quotes.jsonl` 是单 TradingDay 分片。保留策略保留最新 +20 个不同 TradingDay。超过窗口也不会自动删除：旧运行必须先有 +`retention-release.json`，其 `run_id` 和最终 `manifest.json` SHA-256 必须一致，并记录 +带时区的 `released_at_utc`、`released_by` 和 `reason`。研究或验收引用可写 +`evidence-protection.json`： + +```json +{ + "schema_version": "iter22.retention-release.v1", + "run_id": "", + "manifest_sha256": "", + "released_at_utc": "2026-09-09T00:00:00Z", + "released_by": "", + "reason": "" +} +``` + +保护模板： + +```json +{ + "schema_version": "iter22.evidence-protection.v1", + "run_id": "", + "kind": "acceptance", + "reference_sha256": "<64 hex>" +} +``` + +保护标记优先于释放标记；标记损坏时也按保护处理。每次保护跳过、无释放跳过、计划删除 +和已删除结果都会 fsync 到报告根目录的 `retention_audit.jsonl`。显式 `--output-dir` +不扫描其父目录，retention 状态写为 `NOT_APPLICABLE_EXPLICIT_OUTPUT_DIRECTORY`，避免清理 +任意路径。 + +G3 的 `observation_evidence` 可直接机判：第一套真实时段连续有效观察至少 3600 秒、 +合格完成 bar 至少 60、合格盘口窗口至少 60 秒、TradingDay/generation/profile 一致、 +以及 settlement/order/cancel/account-change 写计数全为 0。休市、断代和坏数据不计时。 + +专属回归： + +```bash +/Users/yunjinqi/opt/anaconda3/bin/conda run -n base pytest -q \ + tests/unit/test_ctp_sa_midfreq_example.py +``` + +这些测试覆盖 AC-01/02、AC-05～17、AC-20～24、AC-27、AC-29 的本地可验证部分。 +真实 SimNow 行情、账户费用、结算和成交没有 fixture 替代；只有新生成的网络 evidence +可以把对应项从 `NOT_RUN/BLOCKED` 改为

+依据：[初始需求](初始需求.md)。本文规定交付范围，[设计文档](设计文档.md)规定实现契约，[验收文档](验收文档.md)规定判定方法，[追踪矩阵](追踪矩阵.md)逐项连接需求、设计、任务和用例。 + +## 1. 目标与交付边界 + +在已创建的 `examples/013_3_sa_midfreq_simnow/` 提供自包含的纯碱 SA 单合约策略：使用 CTP 一档买卖价量形成短周期特征，结合已完成的 1 分钟 K 线预测短期方向，经成本与风险过滤后，通过 Backtrader 原生订单生命周期在 SimNow 模拟账户运行。普通持仓目标为 60～900 秒；异常风险退出可以早于 60 秒。 + +本轮已经在三个隔离工作树中形成 SDK/CTP 公共契约、Backtrader Store/Feed/Broker 接入、013_3 策略与运行器、证据输出和测试。同连接原子 arming、恢复、冻结版三仓回归、性能、最终 wheels 和仓外安装消费者验证均已完成 G1/G2；实现状态及验证结果以[实施与验收记录](实施与验收记录.md)为准。尚未完成的范围是第一套 SimNow 的新鲜只读观察与交易闭环，以及研究样本和连续账务观察；这些缺口不得由源码存在、离线 fixture、TCP 探测或第二套 7×24 API

实际月份合约、一个专用 SimNow 账户、一个写入进程；账户内禁止同时运行 013_1、013_2 或其它下单程序。允许分别做多、做空，不加仓、不锁仓、不做跨品种或跨期套利。实盘、HFT 延迟认证、逐笔订单簿重建、自动调参、深度学习服务、Web 前端不在范围内。 + +## 3. 功能需求 + +### FR-01 运行模式与结果身份（P0） + +提供 `replay`、`shadow`、`simnow` 三种显式模式，默认 `shadow`。`replay` 使用本地记录，可启用明确标识的假设撮合；`shadow` 只读行情与账户，不提交订单，不生成模拟成交或 PnL；只有 `simnow` 使用账户订单接口。未知模式、生产环境配置、配置冲突在网络或写入前失败。工程 smoke 与自然信号交易分开标识，不能混入策略收益统计。 + +### FR-02 原生框架与职责边界（P0） + +交易策略继承 `bt.Strategy`，用 `notify_tick`、`next`、`notify_order`、`notify_trade`、`notify_idle` 组织生命周期，通过 `buy/sell/close/cancel` 和 `BtApiBroker` 下单。行情经 `BtApiStore/BtApiFeed` 进入 Cerebro，交易接入使用 `bt_api_py`。SDK 负责 CTP 协议，框架负责事件与订单映射，示例负责 SA 信号和风险预算；不得在示例内直接调用 native Trader API 或另建交易客户端。 + +网络会话始终以 `market_data_only` 启动。Stage A 只读预检完成后，Store 只能通过 SDK 公共原子 arming 契约把同一连接切换为可执行态；proof 必须绑定账户、TradingDay、合约、connection generation、profile、receipt 和 native 身份。示例不得修改私有字段、替换客户端或重连绕过该门。 + +### FR-03 运行环境可核验（P0） + +冻结 Backtrader、SDK、CTP native 组件的源码/制品身份、Python 版本、OS/架构和实际加载位置。当前用户运行目标是本机 macOS/Anaconda base，不能将 Linux 或源码检查结果当成本机原生加载通过。导入 native 的验证在独立子进程执行并记录退出码；崩溃不得在已有订单证据后盲目重试。 + +### FR-04 SimNow 环境与账户预检（P0） + +用于次日市场观察和策略交易的默认环境为 SimNow 第一套、与实际市场时段一致的环境；第二套只能形成 API 工程证据。完整区分行情登录、交易认证/登录、订阅确认、TradingDay、结算确认状态、账户可用资金、持仓、挂单、合约与费率查询。缺失/超时/拒绝/不完整查询不得当作空仓、零费用或就绪。 + +结算确认可能是状态变更：`shadow` 和只读 preflight 仅检查；必要时由单独、明确的 SimNow 准备步骤通过 SDK

元数据与有效规则不一致即阻断开仓。费用按金额比例和每手固定额合计，不能把未知费率设为零。首版允许有日期、来源与失效时间的保守人工费率配置；未取得账户结算费用时只报告估算净收益。 + +### FR-07 一档行情与质量过滤（P0） + +必须取得 bid1、ask1、bid_size1、ask_size1、last_price、累计成交量、持仓量、交易日与事件时间；每个字段带来源和缺失标记。拒绝 NaN/Infinity/CTP 极大无效值、非正报价、交叉盘口、负数量、错误价格格点与过期数据。正常锁盘/零边深度作为不可开仓状态记录。盘口缺失不得回退最新价或 K 线 close 后继续交易。 + +### FR-08 时间与累计量语义（P0） + +保留 TradingDay、ActionDay、UpdateTime、UpdateMillisec、接收 UTC 与 monotonic 时间；夜盘日历日期和结算交易日分开，不能机械拼接 TradingDay 与 UpdateTime。无可靠时间组合的记录隔离。累计 Volume 转为增量后才进入分钟成交量；重复、乱序、断线缺口、盘中重置和跨交易日重置均有明确处理与质量标识。 + +### FR-09 分钟线与因果顺序（P0） + +同一行情源由一个权威 Feed 消费，分发原始 tick 并形成 `[minute_start, minute_end)` 的分钟线。方向指标只读已完成、质量合格的分钟线；当前未完成 K 线只可作为单独标识的观测值，不进入 v0 方向模型。无成交但有报价的行情不能虚构成交 K 线；断流分钟不得以旧 close 补齐为真实数据。必须通过分钟边界、休市、晚到数据和 tick/bar 回调顺序用例。 + +### FR-10 预热、录制与回放（P0） + +支持同一实际合约的录制、断点恢复与确定性回放。首版需至少 60 根合格已完成分钟线和 60 秒有效盘口窗口才允许产生可执行信号；无历史 tick/bar 查询能力时明确等待实时积累，不伪造回填。历史记录必须有时间、合约、质量、来源和校验和，不能把合成样例作为预热市场数据。 + +### FR-11 高频特征（P0） + +至少实现盘口量不平衡、微价格偏离、报价层级 OFI、短窗中价动量/波动和价差成本。用时间窗 1/5/15/60 秒，不以“最近 N 条”假定固定行情频率。将其称为“一档快照特征”；CTP 快照不能还原真实撤单流、逐笔委托、队列优先级或完整主动买卖量。 + +### FR-12 分钟趋势与融合预测（P0） + +至少包含已完成分钟线的 EMA 趋势、1/3/5 分钟收益、ATR/波动和有效成交量信息。v0 为冻结权重的确定性评分，输出方向、分项贡献、质量与成本门，不声称已校准成收益概率。后续候选可训练 1/5/15 分钟预测模型，但只能在训练集拟合，样本外前冻结全部变换及阈值。 + +### FR-13 无前视与可证伪研究（P1） + +在时间顺序数据上进行训练/验证/最终未触碰测试；对最长 15 分钟重叠标签采用至少 15 分钟 purge/embargo，不随机拆 tick。比较无交易、仅分钟、仅盘口、融合模型，费用、滑点和执行假设一致。记录所有尝试候选及失败，不反复看最终测试后改参数。数据不足记 `INSUFFICIENT_EVIDENCE`；合格数据明确否决假设记 `RESEARCH_REJECTED`。 + +### FR-14 入场规则（P0） + +只有预检、预热、数据质量、时段、成本与风险全部通过，且无持仓/挂单/未知订单，才允许入场。融合得分连续满足时间确认与双层同向条件后开一手，信号有短有效期，发送前重新校验价格、可用资金和目标仓位。无合格信号时零交易是合法结果；不得为制造验收成交降低阈值。 + +### FR-15 退出与持仓时间（P0） + +以第一笔开仓实际成交为计时起点，普通信号退出不早于 60 秒，900 秒触发强制退出请求。止损、日损、坏数据、临近休市/收盘、操作员停止优先于最低持仓时间。连续交易小节结束前停止开仓并提前清仓，默认不跨 10:15、11:30、15:00、23:00 等小节边界持仓。 + +900 秒是发起退出的硬期限，不是成交保证；涨跌停、断线或撤单结果未知时需报告超时敞口并持续恢复。不得为了报告满足 15 分钟而虚构平仓。 + +### FR-16 仓位与风险预算（P0） + +默认每次 1 手、最大总持仓 1 手、最大在途开仓 1 手且总潜在敞口不超过 1 手。资金不足不下单，不关闭 cash check。默认模拟日损阈值取 500 元与启动权益 0.5% 的较小值，3 次连续亏损停止新开仓；阈值为待验证的保守工程初值，不是已优化参数。风控使用已实现净损益＋可执行报价估值的未实现损益；不可用数据不能清零亏损。 + +启动权益采用当日第一次完整预检冻结值，日损、连亏锁和请求预算按账户×TradingDay持久化，重启或改run ID不能重置。普通止盈与信号退出均需持仓满60秒，风险例外单独记录。 + +### FR-17 明确的订单语义（P0） + +首版使用对手价限价 GFD＋撤单确认，不声称 IOC。价格按 tick 对齐并在当日涨跌停内。提交、成交、部分成交、拒单、撤单、撤拒、超时逐状态处理；重报之前必须确认旧单已终结并完成必要对账，撤单超时不得被视为撤单成功。禁止无限追价和无限重试。 + +### FR-18 CTP 开平与持仓归属（P0） + +完整保留 direction、offset、hedge flag、今仓、昨仓、可平量与冻结量。使用 SDK 确定 CZCE 合法平仓字段；不得照搬 SHFE 平今规则，亦不得以持仓净额代替长短两侧。外部持仓/挂单或同合约双向持仓使自动启动失败；恢复只处置有本策略证据的订单，不自动平掉其它策略或人工仓位。 + +### FR-19 回报、查询完成性与未知订单（P0） + +订单关联同时保留本地 intent、FrontID/SessionID/OrderRef 和 ExchangeID/OrderSysID；成交按交易日、交易所、合约、TradeID 等稳定身份去重。查询必须带请求 ID、终包、错误码、超时、完整性与连接 generation，迟到旧回调不得覆盖新状态。请求发送后结果不明进入 UNKNOWN，禁止重开；查询完整且与成交/持仓收敛后才能解除。 + +### FR-20 静默风险与受控停机（P0） + +即使没有新 tick/bar，`notify_idle` 或框架等效轮询仍推进超时、最大持仓、连接监控与关闭流程。行情断流停开仓；交易断线或未知订单停发新的风险指令并对账。Ctrl-C、运行期限、日损和普通退出都先撤在途开仓、再平可确认的本策略剩余仓位；不能直接停止 Cerebro 后宣告归零。 + +120 秒 drain 仍不能收敛时，进入 `MANUAL_INTERVENTION` 并持续只读恢复/对账。有效的操作员接管收据只能交接责任，不能证明账户归零或 G4 通过；收据校验通过时以退出码 3 和 `RECOVERY_OPERATOR_TAKEOVER` 结束。SIGINT/SIGTERM 必须先落盘最终恢复证据，再以退出码 3 和 `RECOVERY_FORCED_TERMINATION` 结束，均不是成功终态。 + +### FR-21 持久化与恢复（P0） + +持久化意图先于下单，保存回报、查询批次、持仓和运行配置；进程崩溃后只做查询恢复，不盲目重发旧请求。本机同账户使用排他文件锁，首版不支持分布式多机写入。恢复与启动均核对账户、合约、策略 ID、交易日和源码/参数身份；无法唯一归属则保持人工处理状态。 + +execution arming proof 也纳入恢复身份；它不能跨 connection generation 或进程自动复用。恢复连接先回到 `market_data_only`，完成当前账户/TradingDay/合约/订单/成交核对后生成新 proof，再决定是否重新 arming。 + +耐久账本使用的 `strategy_identity_sha256` 只绑定候选、purpose、冻结配置、源码和稳定策略参数，必须跨进程重启及 admission receipt 正常续签保持不变。receipt hash 只属于当代 `ExecutionArmProof`；续签必须使旧 arming proof 失效并生成新 proof，但不能使同一策略失去对既有账本和持仓的恢复归属。 + +### FR-22 证据与日报（P0） + +输出行情质量、逐次信号及阻断原因、订单成交、费用来源、状态机、风险事件、持仓区间、退出原因、权益和逐交易日结果。原始账户号用不可逆脱敏标识；所有证据有 schema、run ID、代码/配置/数据 hash、时间范围和状态。报告区分假设回放收益、SimNow 观察收益、账户结算值及估算值，零交易日也必须进入日报。 + +### FR-23 操作与交接（P0） + +提供环境模板、配置说明、只读 preflight、shadow、最小 SimNow smoke、自然策略运行、故障恢复及收盘核对步骤。操作员接管使用绑定当前恢复证据的签名收据，须明确其只表示责任交接和非成功退出。命令必须使用用户的 Anaconda Python，文件存在与参数解析通过后才可标为可执行。交付清楚列出外部准备项、责任人、时间窗口、阻断原因及次日失败时的处理步骤。 + +### FR-24 候选与验收身份（P0） + +需求、策略公式、参数、成本、运行环境、所测源码和实际安装制品共同绑定候选 ID。变更核心参数或依赖使对应验收失效；M1 工程通过不等于 M2 研究通过。允许技术就绪而研究未建立的小额 SimNow 研究实验，报告必须标 `RESEARCH_NOT_ESTABLISHED`；已被合格成本评估否决的候选不得改名继续开仓，应形成新候选重新评估。 + +admission receipt 与 arming proof 是不同证据：receipt 表示离线/人工准入，arming proof 表示同一 live connection 的动态只读证据仍一致。两者都必须有效，任一缺失、过期或身份不匹配都不得打开写闸。 + +## 4. 非功能需求 + +| ID | 优先级 | 可测标准 | +|---|---|---| +| NFR-01 | P0 |

手、不跨小节、仅本机 SimNow。runner 会将当前合约、账户和结算状态、第一套 profile、手续费/保证金、native 加载结果、历史数据覆盖和预算参数写入 preflight 与 manifest；恢复无法收敛时另写 `execution_recovery`，并在有经验证操作员接管时附其收据摘要。任一必需证据缺失即关闭写闸。 + +本轮仅检查本地 `.env` 的存在性和必需变量是否非空，未读取任何秘密值。013_3 候选目录没有 `.env`，且运行器不会自动加载父仓库的 `.env`；其它位置存在 CTP 凭据文件，但本轮没有复制或注入它们，因此不能将隔离约束写成“凭据不存在”。当前 G3 的实测阻断是当前主机到获准第一套 MD/TD 前置的 TCP 连接超时，以及 `config.yaml` 的

arming、Backtrader 全量回归、性能、构建和安装消费者验收。013_3 候选目录没有 `.env`，且运行器不会自动加载父仓库的 `.env`；其它位置存在 CTP 凭据文件，本轮没有读取、复制或注入它们，不能把该隔离约束称为“凭据不存在”。本轮没有连接 CTP、确认结算或提交订单。文档描述的预期结果不能填作实测结果；离线 fixture、源码测试、本机 native 文件或 TCP 探测也不能替代第一套 SimNow 的新鲜证据。 + +验收分为文档、工程机制、本机安装消费者、第一套 SimNow 行情与交易、研究经济性五类证据。公式计算正确不证明 Broker 路径正确；模拟回报不证明柜台成交；技术通过不证明持续盈利；本地源码通过不证明已安装包通过。 + +每个运行证据必须绑定 `candidate_id`、run ID、purpose、模式、账户脱敏指纹、真实月份合约、TradingDay、起止 UTC、配置/公式/成本/data hash、Backtrader 与 SDK 源码和制品身份、native 文件身份、操作系统/架构、实际加载路径。人工审阅结论还须记录审阅者、日期和引用文件 hash。任何必需子场景未执行，不得将所属 AC 整体标 PASS。 + +SDK 的自动结算确认基线缺口已经修复：只读会话显式设置 `auto_settlement_confirm=false`，结算确认只能由独立 `--prepare-settlement` 动作触发并随后只读回查。源码测试已覆盖零隐式确认请求、旧 generation/错误 TradingDay 回报隔离和失败不置 ready；真实 SimNow 柜台是否符合该契约仍属于

手限额、合法价格、资金、时段、未知订单和停止门；可以注入明确的工程开仓触发，不能修改自然策略阈值。两次上限覆盖同一候选本轮验收的全部开仓尝试，拒单、未知结果和重启均不清零；必要撤单与风险平仓仍受独立应急写入预算管理。不得为满足闭环再增加第 3 次尝试。 + +自然运行需在开跑前登记日期、时段、候选和观测终止点，预热后至少有一个满足距小节结束大于 930 秒的可入场窗口；不能回看结果后任意截掉亏损时段。自然信号零交易是合法策略结果，能验收“遵守信号门、不强行交易”；**不能证明自然开平执行闭环**。机械闭环已有合格 smoke 时可单独标 PASS，自然执行覆盖记 INCOMPLETE，M1 报告注明限制；不得把自然零交易写成“策略交易闭环通过”。 + +M1工程签收要求G1/G2/G3、G4机械链路与自然观察合规行为通过，终态有完整归零证据；无自然成交时只允许`M1_ENGINEERING_ACCEPTED_WITH_NATURAL_COVERAGE_GAP`，G4自然执行仍为INCOMPLETE。只有自然开平链路也有证据，才能去掉该覆盖限制；M2研究未完成时，总体迭代不得标全量验收通过。 + +R1 经济判据：最终测试按交易日块

将“连续运行和对账”与“经济研究”分别出具结果：前者通过要求每个有效交易日的起止账户状态、成交、费用、资金变动/账户重置解释完整且无未决敞口；后者至少有 20 日、100 个自然闭环交易，按 R1 同类日级统计报告。未经完整账户费用核对只能标估算收益；R1 未通过不允许称研究整体通过。平均值为正也不保证每天盈利。 + +## 4. 功能验收用例 + +AC-01～AC-30 的判据保持不变；当前逐项状态和证据分层见[实施与验收记录](实施与验收记录.md)及[追踪矩阵](追踪矩阵.md)。SDK/CTP 契约已有原子 arming 变更前的完整源码快照，三仓冻结版与性能仍待最终复验；涉及真实账户、行情、成交或统计样本的部分不能因离线夹具通过而把整个 AC 标为 PASS。输入中的行情、费用和多手订单属于工程夹具，不能当作当前合约、当日费率或真实市场结果。 + +### AC-01 模式与结果身份 + +对应 FR-01；设计 D03、D09、D10；门 G1、G3、G4。 + +- 输入：缺省/合法/未知模式，生产 profile，MD/TD 混配配置，同一记录在 replay/shadow 的运行配置。 +- 操作：完成解析和启动路径；在 SDK 写入口布置计数器；分别运行 replay、shadow、simnow 的离线驱动。 +- 可判预期：缺省为 shadow；未知模式、生产和环境混配在网络前失败；shadow 的报单、撤单、结算确认等状态变更计数均为 0，无成交/假设 PnL；replay 的假设撮合显式标识；simnow 工程/自然 purpose 不混用。 +- 证据：配置解析结果、网络/写调用记录、模式 manifest、报告字段快照和被拒配置原因。 + +### AC-02 原生框架交易链路 + +对应 FR-02；设计 D01、D04、D07、D11；门 G1、G2、G4。 + +- 输入：带订单回报能力的 CTP 公共 SDK 替身、真实 BtApiStore/BtApiFeed/BtApiBroker/Cerebro，以及继承 bt.Strategy 的目标策略。 +- 操作：以 tick→完成 bar→原生指标→信号启动开/平意图，注入 accepted、成交与平仓回报；另在 G4 保存真实柜台关联。 +- 可判预期：离线集成中 Broker/Feed/Strategy 不能被纯函数或替身 Broker 代替；策略经 buy/sell/close/cancel 与 notify_order/notify_trade 收敛，回报和持仓数量一致；预检和正式运行使用同一个 Store/Broker/Feed 与 SDK 连接，连接始终从 `market_data_only` 开始，不建第二客户端查询后再重连。Stage A 后只允许 Store 调用 SDK 公共原子 arming API；示例无直接 native Trader 调用、私有 mode 修改、独立交易客户端或手工 next 调用。核心公式单测不能代替本场景。 +- 证据：对象类型/模块位置、原生事件顺序、BT ref↔intent↔CTP 身份映射、SDK 请求与回报、集成断言；真实成交证据另外标为 G4。 + +### AC-03 本机 native 与运行身份 + +对应 FR-03；设计 D03、D10、D11；门 G1、G2。 + +- 输入：正常 native 构建，以及缺 native、错误架构、导入异常/崩溃、加载旧版本等故障配置。 +- 操作：使用用户 Anaconda base 启动独立子进程检查导入及实际使用类；观察退出码/信号和就绪状态。 +- 可判预期：只有目标 macOS/架构 native 成功且实际被 SDK 使用才能通过；Python fallback、stub、吞掉 ImportError 后的包导入成功不能算 native_ready。子进程崩溃不得令父进程就绪或自动下单；存在旧交易记录时先恢复而非盲试。 +- 证据：Python/OS/架构、退出码/信号、native 绝对路径及 hash、绑定类来源、SDK/Backtrader 加载位置、失败模式日志。 + +### AC-04 第一套环境与只读预检 + +对应 FR-04；设计 D02、D03、D10；门 G1、G3、G4。 + +- 输入：第一套/第二套/混配 profile；MD 成功而 TD 失败、订阅拒绝、交易日矛盾、结算未确认、费用或持仓查询超时等场景。 +- 操作：追踪登录后全部 SDK 请求；只读 preflight 查询环境、订阅、账户、结算、持仓、挂单、成交、费率与保证金；独立准备步骤使用夹具验证显式确认及读回；在同一连接尝试有效、缺字段、过期、错账户/日/合约/generation/profile/receipt/native 的 ExecutionArmProof。 +- 可判预期：只读登录零确认请求；结算未确认时不下单并指向独立准备步骤。各能力分别判定，不以 MD 登录成功代替 TD/订阅/账户就绪；第二套只给 API 工程证据，不能放行第一套市场验收；错误/超时不当空数据。只有完整且与当前 session 一致的 proof 能原子解锁 execution；失败保持 `market_data_only`，重连自动撤销 arming。 +- 证据：脱敏 profile 标识、请求分类计数、各预检子项、request ID/终包/错误、结算状态读回；G3 实際观察起止和有效时长。 + +### AC-05 实际合约选择与冻结 + +对应 FR-05；设计 D03、D10；门 G1、G3。 + +- 输入：真实月份格式候选夹具，主连别名，排序并列、交割月、到期不足 5 个交易日、不可交易、缺完整排名和手工选择场景。 +- 操作：选择合约并生成 selection 收据；运行中改变排名、换合约，并注入旧合约持仓/挂单/UNKNOWN。 +- 可判预期：只订阅经 SDK 元数据核对的 CZCE/SA InstrumentID；排序可复现且来源同一完整交易日；手工选择明确 MANUAL_VALIDATED。运行中不随排名变化换月；旧合约未确认归零不得切换，通过后重做预热。 +- 证据：全候选及过滤原因、交易日历、来源/快照时间、稳定排序输出、最终原始代码、换月拒绝与预热记录。 + +### AC-06 元数据、手续费与保证金 + +对应 FR-06；设计 D02、D05、D09；门 G1、G3、G4、R1、R2。 + +- 输入：tick/乘数不符、无涨跌停、过期费率、零/缺失保证金、按额和按手同时计费、开/平/平今不同费用及人工保守配置。 +- 操作：验证价位与资金门，计算开平成本和日报；以夹具 M=20、τ=1、买 1500/卖 1503、1 手、开费 2 元/平费 4 元复核。 +- 可判预期：夹具毛收益 60 元、扣费净收益 54 元；若 spread=1 tick、入出各滑点 1 tick，则往返筛选成本为 3.3 ticks，加 1 tick 缓冲后为 4.3 ticks，move_proxy 必须严格大于 4.3 才过门。以上是假设费用，不是当前 SA 费率。已从成交价体现的价差/滑点不重复扣。未知/失效费率或保证金不能设零；缺结算费用只能报告估算净收益。SA 国内期货不使用永续合约资金费率，跨 venue funding 接口不可成为该策略的成本来源或伪造费用；保证金不是交易收益扣费项目。 +- 证据：元数据/费率来源及有效期、计算输入输出、cash check 与预计占用、估算/实核标志、费用对账差额。 + +### AC-07 一档行情与无静默补值 + +对应 FR-07；设计 D02、D04、D05；门 G1、G3。 + +- 输入：完整盘口，缺 bid/ask/量、NaN/Infinity/CTP 极大值、负值、交叉/锁盘、单边零量、价格不在格点、接收或事件时间过期。 +- 操作：逐字段经过 SDK→Store→Feed→特征→入场判定；仅给 last/close 的场景尝试触发强信号。 +- 可判预期：完整字段保留来源/质量；坏数据产生具体拒绝原因并关闭开仓；盘口缺失不使用 last/close 兜底；锁盘/零深度记录为不可开仓。未通过质量的数据不能污染已就绪的特征状态。 +- 证据：原始与规范记录、quality flags、拒绝计数、信号阻断理由、零开仓断言。 + +### AC-08 交易日、时间与累计成交量 + +对应 FR-08；设计 D02、D04、D09；门 G1、G3。 + +- 输入：夜盘自然日≠TradingDay、周五夜盘归属、节前停夜盘、ActionDay 缺失/错误、跨午夜、壁钟回拨；Volume 序列 100/103/103/105、同毫秒不同快照、同日下降、跨日重置、断线后跳增和乱序记录。 +- 操作：规范事件时间，由 SDK 唯一执行累计量转增量，检查 wrapper 透传和 Feed 直接聚合增量，不再次差分；保留原始接收次序，相同投递序列重复注入，重连递增 generation。 +- 可判预期：以明确日历/字段证据还原自然时间，歧义隔离；不能拼 TradingDay+UpdateTime。无缺口量序列首条为基线，后续增量 3/0/2，累计新增 5；首条不灌入 100。重置/断线缺口标不完整，重复不双计，同毫秒有效变化不丢弃；乱序与晚到的量归属不能靠无说明重排修正。壁钟回拨不延长 TTL/持仓期限。 +- 证据：原始四个 CTP 日期时间字段、UTC/monotonic、日历版本、归一化/隔离结果、量基线迁移与各分钟增量核对。 + +### AC-09 分钟边界和因果顺序 + +对应 FR-09；设计 D04、D05、D09；门 G1、G2、G3。 + +- 输入：分钟边界前 1ms、边界整点、end+499ms/end+500ms；水位内晚到、封闭后晚到、缺流/纯报价/休市分钟；同批次 tick/bar 竞争。 +- 操作：一个权威 Feed 消费相同记录，以线上原次序和确定性回放分别运行；捕获 notify_tick、bar 交付、指标更新、next 和每次决策身份。 +- 可判预期：区间为左闭右开；bar 在允许水位且实际交付后才被策略使用；未完成/未交付 bar 不进入方向特征。晚到快照不改累计量基线和已接受的 OHLCV，可能改变增量分钟归属时将该桶及相邻受影响桶标 ORDERING_VOLUME_GAP；封闭后晚到使当前依赖链失效并停开仓，不能改已用 bar/信号。无成交不虚构 OHLC，无行情不以旧 close 补真实 bar；一个决策版本最多一个 intent。两份运行摘要一致且无同队列双 Feed 竞争消费。 +- 证据：ingest_seq、bar start/end/available_at、分钟 OHLCV 预期表、回调事件轨迹、意图去重断言和回放 hash。 + +### AC-10 预热、恢复与录制回放 + +对应 FR-10；设计 D04、D09、D10；门 G1、G3。 + +- 输入：59/60 根合格 bar，59/60 秒盘口，坏 bar、合成/错误合约/旧候选历史，休市后、换日/换合约和校验损坏记录。 +- 操作：逐边界推进 ready 状态，加载存档、重连并回放；无历史接口时从实时记录积累。 +- 可判预期：全部预热条件同时满足才执行；错误身份和合成记录不能充市场预热。休市后至少有一根当前小节新封闭 bar、60 秒合格盘口及有效连续收益锚点才开闸，连续收益不跨空档；换日/换合约重新 bar 预热。断点恢复验证时间/合约/hash，损坏时拒绝；无回填能力明确等待。 +- 证据：warmup 计数与阻断原因、历史 manifest/hash、状态加载结果、G3 60 分钟和 60 bar 的独立时长/数量证明。 + +### AC-11 一档快照特征公式 + +对应 FR-11；设计 D05；门 G1、R1。 + +- 输入：静态/变价盘口、零分母、间隔不等快照、1/5/15/60 秒边界、15 秒锚点过期、60 秒有效变动不足 20 次。 +- 操作：以手算/独立参考实现比较 imbalance、microprice、OFI、动量和波动；改变消息密度但保持相同分段盘口路径。 +- 可判预期：手算夹具 b=100、a=101、B=9、A=1、τ=1 时 mid=100.5、imbalance=0.8、microprice=100.9、micro_dev=0.4；买卖量互换时偏离方向反转。公式与冻结定义一致，imbalance 时间加权不被高频重复推高；1 秒收益锚点不晚于 t−1 秒且距锚点≤500ms。缺锚点或无效窗口给 invalid 而非 0；OFI 被称为报价层级变化，不宣称真实撤单流或排队优势；分项贡献可解释。 +- 证据：独立预期计算、边界参数、各时窗输出、无效原因、时间加权积分和消融清单。 + +### AC-12 分钟趋势与融合评分 + +对应 FR-12；设计 D04、D05；门 G1、R1。 + +- 输入：完成 bar 的趋势/反向/横盘序列，EMA/ATR minperiod 不足、缺连续分钟、score 在 ±0.35 周围的边界。 +- 操作：原生 EMA(5/20)、ATR(14) 与独立参考计算比较；生成 H/K/score、move_proxy 与全部分项。 +- 可判预期：仅已完成且可用 bar 进入指标；1/3/5 分钟收益的真实分钟锚点有效，无缺口填前值；volume_ratio 分母是同 TradingDay 前 20 根有效 bar 且不含当前 bar，20 根均量 100、当前 200 时比值=2，零分母/缺样本阻断入场。融合权重与配置 hash 一致，输出 uncalibrated_score；不得把分数转写“盈利概率”，训练流程不能混入实时回调。 +- 证据：bar/指标/分项逐点对照、ready/minperiod、冻结权重、预测类型和候选版本。 + +### AC-13 研究无前视与否决机制 + +对应 FR-13；设计 D09；门 G1（机制）、R1（经济）。 + +- 输入：具 available_at 的真实快照，1/5/15 分钟重叠标签、跨划分/跨合约记录；未达样本与达到覆盖但亏损的两类数据集。 +- 操作：冻结候选/划分/hash 后比较无交易、仅分钟、仅盘口、融合；对未来特征注入、随机 tick 拆分、最终测试反复调参设计拒绝场景。 +- 可判预期：时间前后和 ≥15 分钟 purge/embargo 可机器校验；训练变换只拟合训练集；撮合最早发生在决策/延迟后的可执行报价，不用本 tick mid 成交。覆盖不足为 INCOMPLETE/INSUFFICIENT_EVIDENCE；合格经济门失败为 RESEARCH_REJECTED，失败候选保留记录并禁止自然开仓。 +- 证据：冻结登记、训练/验证/最终测试清单、标签时间范围、消融结果、全部尝试账本、日级收益/置信区间/压力结果。 + +### AC-14 入场一致性与零信号 + +对应 FR-14；设计 D05、D06；门 G1、G4。 + +- 输入：通过所有门的正/负向信号，以及逐一失败的预检/预热/成本/时段/资金/质量门；持仓、活动单、UNKNOWN；2 秒/3 快照、bar 龄 90 秒边界与失效意图。 +- 操作：重复发送同版本信号，发送前改变盘口/可用资金；运行无自然合格信号的已登记时段。 +- 可判预期：双层同向、得分/确认时间/快照数及全部门同时通过才生成最多 1 手开仓；无新有效报价不能靠 idle 满足确认。方向翻转、分数跌破阈值、bar 版本变化、任一质量/风控门失效均将确认时间和快照数清零；bar.end 距当前事件时间超过 90 秒禁止开仓。意图提交延迟超过 1 秒失效，不沿用旧价格；零交易形成明确原因统计，不降低阈值换成交。 +- 证据：逐门判定、信号版本/时间、提交前重校验、真实或夹具订单数、零交易日报。 + +### AC-15 持仓时钟与失败退出 + +对应 FR-15；设计 D06～D08；门 G1、G4。 + +- 输入：首笔源成交时间及迟到回报、缺失/不可信源时间、59/60/899/900 秒边界；提前止损/止盈、日损、数据失败、收盘；涨跌停、交易断线、无法撤单/平仓。 +- 操作：从首笔实际成交计时，通过 idle 推进期限；在无成交的退出请求后检查策略状态与报告。 +- 可判预期：普通信号退出和止盈不早于 60 秒，止损/日损等风险优先；源成交 UTC 按时钟不确定性映射为 first_fill_earliest/latest 双界，900 秒最大期限按 earliest，60 秒普通最短期限按 latest。源时间不可信时分别以已知发送/成交回报接收时刻作保守双界；迟到回报既不能延长最大期限，也不能使实际未满 60 秒的仓位普通退出。仍不明则立即进入风险退出/对账；900 秒或小节结束前 30 秒按先到期限发起退出。无法成交时保存超时敞口，不能宣称满足持仓上限或 STOPPED_FLAT；收盘不删除未决仓位。 +- 证据：首笔 fill、计时事件、退出请求与成交的独立时间、阻碍原因、未决敞口和最终查询。 + +### AC-16 敞口与日内风险 + +对应 FR-16；设计 D05、D06、D08；门 G1、G4。 + +- 输入：已成交+在途的组合，低资金、冻结资金变化，启动权益的 0.5% 高于/低于 500 元，连续 3 次亏损和跨 TradingDay。 +- 操作：提交竞争信号，按多仓 bid/空仓 ask 计未实现损益；注入坏报价、费用变更和未知回报。 +- 可判预期：总潜在敞口≤1 手、cash check 始终开启；日损使用 min(500, 启动权益×0.5%)，含费用和未实现损益；坏数据不清零损失。权益基线、日损、连续亏损、尝试/写入计数按账户×TradingDay 持久化，重启/改 run/改候选不能清零；当日基线无法恢复则停开仓。日损/连续亏损后停新开仓并受控退出，合法新 TradingDay 且完整对账后才能重置。 +- 证据：仓位/挂单联合账本、资金与费用快照、风控阈值、触发事件和写入预算记录。 + +### AC-17 订单类型、撤单与部分成交 + +对应 FR-17；设计 D02、D06、D07；门 G1、G4。 + +- 输入：GFD/未知 TIF、价格格点/上下限，拒单、撤拒、超时、成交先于 Accepted、成交与撤单交叉；多手部分成交仅作为通用 Broker 夹具。 +- 操作：捕获 SDK/native 字段映射，推进 3 秒开仓超时和 5 秒撤单等待；验证部分开仓撤余量、部分平仓续平、退出两次重报上限。 +- 可判预期：GFD 真实映射，未知 TIF 不静默转 GFD；价格合法。发撤单不等于已撤，旧单未终结不能重报；撤单超时进 UNKNOWN；实际成交先记账并开始风控；剩余数量精确，不无限追单。 +- 证据：请求字段、原生 Broker 状态转换、成交/撤回报次序、订单余量、重报与预算计数。 + +### AC-18 开平、今昨与持仓归属 + +对应 FR-18；设计 D02、D03、D07；门 G1、G3、G4。 + +- 输入：CZCE 多/空、今/昨、冻结/可平夹具，未知 offset/hedge，外部持仓/挂单、双向仓和本策略可恢复仓。 +- 操作：验证 SDK 公共映射、Broker 订单字段及完整持仓查询；尝试启动或恢复，再在 G4 对实际平仓回报核对。 +- 可判预期：长短今昨分别保留，不净额抵销；依官方 CTP Mini API 契约，CZCE 只允许 generic `close`，`close_today`/`close_yesterday` 必须在 native 调用前拒绝，不借用 SHFE/INE 规则。多头可平量扣 `LongFrozen`，空头可平量扣 `ShortFrozen`；外部/不明归属使自动接管失败，不自动平人工仓。离线契约 PASS 不代表柜台已接受；G4 仍须实际请求/回报/成交证据。 +- 证据：映射测试表、query 明细、持仓归属依据、实际 offset/hedge 请求和成交、拒绝原因。 + +### AC-19 查询终包、去重与未知结果 + +对应 FR-19；设计 D02、D07；门 G1、G3、G4。 + +- 输入：多包、空成功终包、空但无终包、有 records 后错误、超时后迟到、交错 request ID/旧 generation；重复 TradeID、会话切换、OrderSysID 延迟。 +- 操作：分别跑账户、订单、持仓、成交、费率查询，查询中继续注入成交；在发送后无回报处中断，再恢复对账。 +- 可判预期：只有成功终包且身份匹配才 complete；空但未完成不能表示零仓/零费。旧回调不污染新快照；成交按稳定复合身份恰好计一次；订单与成交身份双向关联；连续两次完整快照与期间事件收敛后才解除 UNKNOWN。平仓进 COOLDOWN 及其转 FLAT 前均需两次一致查询屏障，未匹配回报不为零则不能重开；迟到成交立即撤销 FLAT 资格。订单查询不得替代缺失成交查询。 +- 证据：逐请求 accumulator/终包/错误/超时、generation、事件起止序号、去重键、两轮收敛差异和 UNKNOWN 解除依据。 + +### AC-20 静默风险与受控停机 + +对应 FR-20；设计 D06、D08；门 G1、G4。 + +- 输入：无 tick/bar、行情超 2/5 秒、交易断线、休市、Ctrl-C、运行期限、日损，及 drain 超过 120 秒仍有仓/单的情况；另含有效/无效的 `operator_takeover.json` 与 SIGINT/SIGTERM。 +- 操作：通过真实 Cerebro idle 调度推进时钟，在各订单状态发出停止；分别验证可收敛、无法收敛、已签名人工接管和强制终止的退出。 +- 可判预期：idle 目标轮询≤250ms，持续执行超时；休市不误判行情故障。停开仓→撤确认可撤开单→对账→平可确认本策略余额→最终核对；不提前 runstop。120 秒未收敛停止自动重报、进入 `MANUAL_INTERVENTION`，但进程继续只读回报/定时对账/告警直至归零或可核验的操作员接管。接管文件必须以 `backtrader.ctp.operator-takeover.v1`／`takeover_execution_recovery`、当前恢复证据身份和 HMAC 校验；验证通过只交接责任，以退出码 3 和 `RECOVERY_OPERATOR_TAKEOVER` 结束，不表示归零或 G4 通过。SIGINT/SIGTERM 先落盘最终恢复证据，再以退出码 3 和 `RECOVERY_FORCED_TERMINATION` 结束；强制终止不标成功，不删除账本。 +- 证据：idle 时间序列、停止原因、drain 各阶段、`execution_recovery`、接管收据摘要或拒绝原因、剩余单/仓/unknown、最终状态和待办。 + +### AC-21 耐久意图、锁与重启恢复 + +对应 FR-21；设计 D06～D08；门 G1、G4。 + +- 输入：意图写前、写后未发送、发送后未记确认、收到成交未落账、撤单交叉等断点；第二本机进程；账户/候选/交易日身份变化。 +- 操作：故障注入杀进程并重启；验证 OS 锁释放、新进程恢复顺序及耐久提交；注入重复历史回报；分别轮换 run ID、续签 receipt，以及修改 candidate、源码、冻结配置或稳定参数。 +- 可判预期：SDK 是唯一权威交易耐久账本，示例仅保存分数/风险政策；发送前持久化成功，写入失败禁止开仓。相同账户同时只有一个写者；重启先恢复 `market_data_only` 并查询，不盲目重发旧 intent 或复用 arming proof；重复成交不增仓，旧 monotonic 不能复用；身份不能唯一归属时保留人工处理，不自动清空账本。run ID 和 receipt 正常续签不改变稳定策略身份，后者仍使旧 arming proof 失效；candidate、源码、配置或稳定参数变化必须改变稳定身份。只有当前连接的新 Stage A proof 可重新 arming。 +- 证据：事务/崩溃点、锁竞争结果、恢复请求次序、源码/账户身份核对、幂等成交账本及最终对账。 + +### AC-22 审计、日报与收益分组 + +对应 FR-22；设计 D09、D10；门 G1、G3、G4、R2。 + +- 输入：正常/零交易/亏损日、跨自然日夜盘、缺费用、人工资金变动/SimNow 账户重置、smoke 与自然交易并存，以及 `MANUAL_INTERVENTION` 的接管或强制终止报告。 +- 操作：从原始回报独立重建逐笔和逐 TradingDay 报告，对比账户变化；检查每次执行/阻断理由与恢复终态。 +- 可判预期：全部日期纳入、夜盘按结算交易日，smoke 独立排除；毛收益、实际/估算费用、未实现收益、入出金/重置可分解。缺费不伪造 verified net；shadow 无成交/PnL；任何无法解释的账差使账务核对不通过。恢复未完成时 manifest 必须保留 `execution_recovery`，如有操作员接管则保留已验证收据摘要；二者都不能使日报写成账户归零、G4 PASS 或 R2 已完成。 +- 证据：manifest、signals/orders/trades/risk、reconciliation、`execution_recovery`、逐日报告、账户指纹和输入→报告重建差异。 + +### AC-23 可执行操作与交接 + +对应 FR-23；设计 D03、D08、D10、D11；门 G0、G1～G4。 + +- 输入：干净配置模板、缺配置/无效模式、只读 preflight、shadow、smoke、自然运行和恢复流程，以及操作员接管/强制终止场景。 +- 操作：实施后逐条验证文件存在、CLI help/参数解析；由另一操作者按 README 在正确阶段执行并完成收盘核对、接管收据校验和退出码确认。 +- 可判预期：全部 Python 命令用用户 Anaconda base；不存在的命令明确设计示例；无复制 `.env` 或硬编码凭据。接管收据必须恰有 `schema_version`、`action`、`approval_key_id`、`run_id`、`account_fingerprint`、`trading_day`、`instrument`、`recovery_evidence_sha256`、`acknowledged_at_utc`、`signature_hmac_sha256`，并绑定当前 run/账户指纹/交易日/合约/恢复证据，使用 `ITER22_APPROVAL_HMAC_KEY` 验签；有效接管产生退出码 3／`RECOVERY_OPERATOR_TAKEOVER`，SIGINT/SIGTERM 产生退出码 3／`RECOVERY_FORCED_TERMINATION`，二者均不签作 STOPPED_FLAT 或 G4。失败步骤包含责任人、环境/时间窗口、恢复动作和解除判据；次日仅只读可用时准确报告限制。 +- 证据：CLI 检查、执行记录、交接收据摘要、退出码、前置清单和未决事项；命令排版与参数解析不替代实际运行验证。 + +### AC-24 候选冻结与门禁失效 + +对应 FR-24；设计 D09～D11；门 G1～G4、R1、R2。 + +- 输入：相同版本号但不同源码/wheel、策略权重/费用/profile 变化、旧门禁收据、研究未建立/已否决候选。 +- 操作：校验收据绑定并尝试启动；比较 smoke/自然运行证据；验证核心变更后的失效范围。 +- 可判预期：凭 hash 和实际加载身份而非版本号放行；依赖/参数变化使相关旧证据失效。研究未建立可以在技术约束下做 1 手实验并显式标记；已否决候选不可只改 ID/名称继续自然开仓，须有实际修改、重新登记，并对原否决原因通过冻结复核门且使用新的未触碰样本。机械/自然/经济结论分别输出。 +- 证据：冻结 manifest、收据校验、变更影响表、拒绝日志、研究状态与允许模式表。 +- 补充判据：admission receipt 与 ExecutionArmProof 必须分别验证；后者须绑定当前账户、TradingDay、instrument、generation、profile、receipt 与 native/package 身份。错配或过期 proof 必须保持 `market_data_only`。 + +## 5. 非功能验收用例 + +### AC-25 回调性能与非阻塞查询 + +对应 NFR-01；设计 D02、D04、D08；门 G1、G2。 + +- 输入：10 万条预先冻结快照及查询延迟/限流夹具，登记本机硬件、负载与记录开关。 +- 操作：测 tick 进入处理到信号产出耗时，记录完整样本分位数；让 SDK 查询阻塞 5 秒并继续驱动订单、行情与 idle。 +- 可判预期：离线处理 P99≤20ms；策略回调不发同步网络请求，不因查询阻塞停止处理回报或风险超时。报告不将离线值当 CTP 网络往返或交易所排队延迟。 +- 证据：样本数/原始耗时/分位数、硬件和负载、测量边界、线程/任务调用证据及限流行为。 + +### AC-26 事件可靠性与故障收敛 + +对应 NFR-02；设计 D02、D07、D08；门 G1、G4。 + +- 输入：行情和订单审计队列满、回报重复/乱序/延迟、断线/重启及查询期间成交等注入矩阵。 +- 操作：对每个提交事件编号，核对输入、持久化、处理、丢失计数和最终账户；执行故障后恢复。 +- 可判预期：订单/成交/对账事件无静默丢失；行情丢失有计数/缺口且停开仓；未知不重开、退出失败不归零。无法收敛时完整呈现残余，不能为了让测试结束抹掉状态。 +- 证据：注入清单、事件序号核对、耐久日志、丢失计数、状态迁移和故障最终断言。 + +### AC-27 凭据隔离与脱敏 + +对应 NFR-03；设计 D03、D10；门 G1、G2。 + +- 输入：仅含人工哨兵字符串的伪凭据、会产生连接异常/认证拒绝的离线夹具，仓库环境模板。 +- 操作：触发所有配置/异常输出，扫描日志、报告、traceback、manifest 和待提交文件；核对忽略规则。 +- 可判预期：哨兵秘密未出现在任何可发布证据；账户号使用脱敏指纹；模板无真值且 .env 被忽略；异常不 dump 连接对象。本用例不读取已有真实 .env，也不能用“未发现关键词”替代完整输出路径覆盖。 +- 证据：扫描范围/规则/零命中、人工哨兵测试、忽略规则与待提交文件清单，均不包含真实凭据。 + +### AC-28 兼容性与安装消费者回归 + +对应 NFR-04；设计 D01、D11；门 G1、G2。 + +- 输入：修改前后公共 API 清单、受影响 CTP 与另一个实际消费者/跨 provider 契约，冻结源码与 wheel。 +- 操作：检查无新增元类；按影响运行现有 Store/Feed/Broker/idle 集成；在源码态和安装消费者态分别运行。触及时钟/minperiod/line 时运行全部策略回归。 +- 可判预期：原 API/行为兼容，通用变更具有复用语义证据；安装消费者确实使用目标 site-packages 和预期依赖，不能从源码偷渡；全部必需回归有当前结果，历史绿灯与小集合不替代全策略门。 +- 证据：API 差异、消费者清单、测试结果、pytest 实际 backtrader 路径、源码/wheel/native hash、所需全套执行结果。 + +### AC-29 确定性与解释完整性 + +对应 NFR-05；设计 D04、D05、D09、D10；门 G1、G2。 + +- 输入：相同有效事件序列/候选/配置，以及乱序、晚到、相同时间戳的固定录制；控制可回放时钟和随机 seed。 +- 操作：重复两次回放并独立重算摘要，改变宿主执行速度而保留 Clock 虚拟时刻与虚拟 idle；逐信号追踪分数、成本、质量、资金与订单状态。 +- 可判预期：归一化后的信号/意图摘要完全一致，非业务 run ID/记录时间不参与业务摘要；无 tick 间隔仍有虚拟 idle 推进，确认/撤单/最大持仓不随宿主回放速度变化；不能通过删除影响执行的时间字段制造一致。每次下单与不下单均有可解释原因和输入身份。 +- 证据：两次输入/业务输出 hash、字段归一化规则、差异报告、决策解释覆盖统计。 + +### AC-30 有界资源与持久化失败 + +对应 NFR-06；设计 D07、D08；门 G1、G2。 + +- 输入：冻结速率的 4 小时压力负载，行情/审计峰值、磁盘低于 1GB、写入失败、轮转和研究冻结数据引用。 +- 操作：测队列/窗口/磁盘/RSS；压满各队列并触发轮转/保留规则；在已有持仓和新开仓两种状态下拒绝持久化写入。 +- 可判预期：队列、窗口和存储有上限且无静默订单事件丢失；空间/耐久失败关闭开仓并保全退出/对账优先级；被研究或验收引用的数据不清理。默认20条/秒、每分钟5秒200条/秒运行4小时，进程树RSS峰值≤512MiB；前30分钟后，每30分钟P95 RSS，末窗较首稳定窗增长≤max(32MiB,10%)。如需依本机基线修订，必须验收前冻结且同步需求与配置，不得失败后放宽预算。 +- 证据：速率/样本量/负载配置、每分钟 RSS/队列/磁盘曲线、冻结预算、轮转目录索引、故障日志和残余风险状态。 + +## 6. 测试入口与执行限制 + +以下路径构成本迭代的 Backtrader 验证面。新增迭代测试已创建；冻结版执行状态以[实施与验收记录](实施与验收记录.md)为准。任何本地通过都不证明当前环境可连接或可下单。 + +| 层 | 已存在的参考路径 | 必须补充的迭代覆盖 |

09/83] feat(ctp): add barrier/cohort/option-commission framework layer and O2 entry integration - feeds/barrier.py: shared multi-leg minute barrier with frozen clock mapping, scope lifecycle and anti-replay watermarks (LOCAL_BARRIER_SUBSET_PASS) - feeds/ctpcohort.py: CtpQuoteCohortValidator for three-leg tick cohorts - commissions/ctpoption.py: premium-style option comminfo with role-based fees (LOCAL_OPTION_ACCOUNTING_SUBSET_PASS) - btapistore.py: V2 bundle arming/recovery delegation, query time-window validation, entry-approval arm path, budget capability passthrough; stop-time market_data_only handling limited to CTP (fixes the 1ff2ea2a regressions on non-CTP owned-SDK restarts) - btapibroker.py: option accounting consumption, quarantine semantics - setup.py: exclude

bar 的保守年龄 +上限为 910 秒。期限使用显式 monotonic clock；`notify_idle()` 没有可信时钟时会锁存拒绝， +不会把最后一根 bar 当作当前时间。15 分钟 OHLC 触价和成交量不能证明 60 秒内成交，报告 +会保留 `FILL_TIMING_UNKNOWN` 与 0 个 confirmed fill；只有带明确时间区间的合成 execution

+`account_fingerprint`、TradingDay 和 connection generation；任一非空、缺失或跨代际 +结果都会返回 `BLOCKED`。 + +非纯 mock 运行时优先调用 `BtApiStore.get_ctp_bundle_preflight_snapshot(..., +read_only=True)`，收口账户范围的公共 Store 证据；退出时调用两次 +`BtApiStore.get_ctp_reconciliation_snapshot()`，不自行复制 native 查询实现。 +预检通过后，运行时只组装一条 +`BtApiStore(provider="btapi") → BtApiFeed（三腿）→ BtApiBroker(provider="btapi") → Cerebro → Strategy` 链，Broker 使用 +`market_data_only`。退出前必须完成两轮身份一致且内容稳定的 reconciliation。即便 +工程链路通过，报告仍固定为 `NO_NATIVE_CONFIRMATION`，不会声称发生成交、平仓或真实 +收益；真实 native 启动必须由 SDK-owned launcher 注入 API 并另行满足授权与外部验收门。 +当前 Iter22 信任根缺失时，engineering_smoke 仍固定 `market_data_only=true`、 +`order_write_allowed=false`，不会生成、读取或写入任何密钥，也不会解除该限制。 + +本地 smoke 例： + +```bash +/Users/yunjinqi/opt/anaconda3/bin/conda run --no-capture-output

+郑商所现行《期权交易管理办法》第42条明确将期货多头加卖看涨、期货空头加卖看跌等两腿结构称为“备兑期权套利”。所以不能笼统回答“两腿不是套利”；交易所组合业务称谓与数学意义的无风险套利须区分。第42、48条涉及组合确认和保证金规则，不能自行假定逐腿开仓时立即享受结算组合优惠。[郑商所办法](https://www.czce.com.cn/cn/content_file/flfg/zcjywgz/ywbf/2026/5/889576021a584f73abd8fdac4205188b.pdf) + +CME 的 conversion 定义即买期货、买看跌、卖看涨，并要求期权同行权价、同到期；此前文档使用的是这一标准结构。[CME Glossary](https://www.cmegroup.com/education/glossary) + +忽略利率与费用、假定标的和结算完全匹配时，`C_T-P_T=F_T-K`。因此一手多期货加多P减C的终值部分为 `F_T-F_0+P_T-C_T=K-F_0`，C/P把期权的非线性部分组合成线性敞口，再由期货抵消。这解释了三腿的来源。非零融资、美式提前行权、实际逐日结算和不同合约规则不能直接忽略。 + +只有期货与一个期权时，期权的非线性敞口一般仍然存在。可以通过 delta 对冲减少即时方向风险，但手数不必是一比一： + +`组合delta = 期货有符号手数 × 期货乘数 + 期权有符号手数 × 期权乘数 × 期权delta` + +例如期权delta约为−0.5、乘数相同时，一手多期货与两手多看跌可以近似即时delta中性。这是两种合约、两条腿，期权腿有两手；delta变化后仍需调整。本文的一比二资金情景没有计算有效delta，因此不将其标记为已经中性。[CME对冲教材](https://www.cmegroup.com/articles/files/2023/pro-workshop-series-post-webinar-recording-week4-slides.pdf) + +## 6. 对后续三个迭代的影响 + +模板应允许不同策略族提供有界的 `LegSpec[]`、定价模型、整数手数和风险约束，共用行情、执行状态机、敞口账本与恢复机制。腿数由策略族决定；低频、中频、高频控制的是观测、信号与执行节奏，不应决定必须三腿。 + +后续应分别冻结两腿备兑、两腿delta对冲和三腿平价候选，逐族核验经济模型。美式期权不因行权方式直接从全部研究名单删除，但不能硬套欧式平价等式。资金合格不能直接认定高频资格；高频仍需独立的延迟、队列、流动性和真实成交证据。 + +原三份迭代的初版文档保留为三腿候选的设计快照；本文纠正其对整体研究范围的推断，并不等于已完成两腿策略实现、原交易门改造或新的交易准入验收。 + +## 7. 验证与证据

+因此现有原始回报不能直接充当某价格路径下的已验证卖方总保证金；禁止未经owner规则证明就使用 `max(FixedMargin, MiniMargin)`、`FixedMargin + Royalty`，也禁止把 Royalty 当作当前成交权利金。原生零输入不证明“当前价”，交易所字段不能冒充目标账户柜台金额。 + +Instrument字段已能识别期权、C/P、乘数、价位、标的与到期；原生Instrument不证明exercise_style、premium_style、settlement_style，必须另有显式带来源规则。option_commission回报包含开/平/平今的ByMoney与ByVolume：它们是分别按成交金额和手数计费的两维，不是同一值的别名。合法的同时非零应相加，零值须有完整字段证明，缺值不能默认0。

+O2的输出是有限风险预留结果和原因，绑定candidate/cycle/各腿范围/account/day/generation/有效期；它不代表独立操作批准，也不能覆盖策略经济门。O1与Broker只读取此结果，不复制一套账户预算。当前SDK源码尚未发现完整budget/reserve实现，因此O2仍为明确开发缺口。 + +### 10.4 O2 → O3：今昨持仓事实与有限执行计划分开 +

实现D24-05要求的显式冻结wall/mono映射，保守deadline同时受第一seal+2和映射后的T+2约束；D23受T+10约束。barrier不得在common available_at对应的可信单调时刻之前输出可消费READY。后续bar自己的wall不能重定基准以延长期限。调整两例合成replay producer，让同一录制域内的时间映射及seal/available相互一致；特别是014_1当前seal=.5/.6/.7而available=T+2，不能作为提前决策证据。 | +| B-CP02 / P1：时钟故障未使pending失效 | 同域seal mono=.5→.4→.7仍READY；advance(1)后advance(.9)虽返回CLOCK_REGRESSION，之后C/P仍凑齐READY；advance(None/NaN/Inf/-1)返回空，旧pending也仍READY；显式now=.1/.11/.12却给seal=.5/.6/.7仍READY。 | 明确同域输入与观测时序；未知、非有限、负值、回退或未来seal不能静默忽略。使受影响pending和未用确认永久失效，故障锁存或通过明确的新scope重置恢复；单个后续正常bar不能自动洗掉故障。任何显式now都必须携带/绑定可信同域身份，不将裸数字或上一tick时间猜成当前时间。 | +| B-CP03 / P1：不完整桶伪称完整分钟 | 三腿实际区间都是`[T-1s,T)`，各自timeframe_seconds=60、complete=true，barrier仍READY。 | 以实际bucket_start/end验证策略要求的完整60秒/900秒区间和会话边界，而不是只信任自报timeframe。时长错配、partial interval等不可进入普通决策。保留正确两腿/三腿固定桶正例，增加两个策略周期的长短桶负例。 |

generation/session/rules/domain等scope冲突须废弃相关旧pending并向consumer明确reset，不能仅返回一次错误而保留半个旧集合。规定新scope的公开重置/重建入口及消费者清空历史/确认行为；不能以新代际的正常bar悄然复活旧scope或跨进程monotonic。永久退休语义与有界history仍须保留。 | +| B-CP05 / P1：报价冻结身份及公共typed证据不完整 | 已冻结ingest_seq20/price10后，`accept_quote`接收同seq/price999，accepted=true并返回999，原冻结集合虽未改变。补充：source skew0而receive skew700ms仍READY；直接validate `CtpQuoteEvidence`后丢失bid/ask/bid_size/ask_size；同一typed quote放进BarEvidence.quote_events先vars化后反而CLOCK_MODE_MISMATCH/accepted0。 | 同seq检查必须验证冻结内容一致；变造拒绝，或只返回原冻结事件。不要将后来传入的新对象作为已冻结quote返回。按D24-05同时约束source与receive跨度。typed适配应在冻结前通过同一个明确适配契约规范化，保留盘口、数量、来源与误差证据；直接检查与经BarEvidence→MinuteDecisionInput路径语义一致。该修复是公共输入合同，不要求提前完成FQ2积分算法。 | +| B-CP06 / P1：F01 early Partial竞态仍丢事实 | 使用实际`_submit_next_leg`，buy在返回订单前同步回调Partial(.5)，之后方法见HALTED提前返回，pending_ref仍None。再给相同ref的Completed(1)，只得到UNEXPECTED_ORDER_CALLBACK，projection仍只有partial。 | 在HALTED停止新腿的同时保留已经确认的订单ref/当前腿关联。测试必须覆盖真正submit调用栈：同步Partial→submit返回→延迟Completed/Canceled；后续事实完整、终态幂等、零额外腿。不能用一直保持submission_in_flight=true的测试替代此时序，也不能通过HALTED后继续开下一腿修复事实丢失。 | + +B-CP01的公共证据输入必须明确：至少有mapping identity、原始可信source、clock domain、generation、冻结anchor wall UTC、对应anchor monotonic、已知有限error bound及其规则来源/最大阈值。它来自独立可信采样或录制生产者，不能从正在被校验的bar自身wall与mono倒推出“自证正确”的映射。按误差区间取保守截止并验证后续seal与wall的一致性；未知error bound、跨域、过大误差、wall跳变均拒绝。为replay提供显式且可复算的合成mapping是允许的，必须标明synthetic，不能冒充live来源或用CPU速度模拟时效。 + +当前`BarEvidence`没有上述映射和误差字段，因此B-CP01属于公开合同未完成；单纯再加一次`seal_received_at<=T+2`并不能修复反例。若调整公开构造签名，既有fixture和本验收脚本的合法输入适配应同步加明确录制证据；保留原攻击场景与期望，不能改成宽松默认或删除反例。 + +014_2 tick回调目前还会把缺失/输入已有的scope、quality、receive mono等字段改写为replay默认值，且示例只记录cutoff诊断，不产生交易。FQ2接入实际特征时必须将合成事件生产移到明确fixture producer，消费端验证原始输入，不能沿用这种回调内补造来源的方式。该项不能作为真实quote provenance正向证据。 + +### 12.4

请求发送与返回观测由Store自己采样，不能接受QueryResult覆盖这些外层观测。记录同一请求的本机monotonic发送/接收值并验证有限及不回退；明确wall回退导致本轮证据失效，不能靠后续新snapshot给该query续期。若需要额外检查wall与mono elapsed差值，阈值必须来自已说明的采样精度合同，不能恢复任意秒数容差。 +3.

公开输入是独立操作方已经签名的批准制品，SDK只验证和兑换本进程opaque能力；SDK/example不持有或生成生产私钥，不提供“策略自己批准自己”的默认信任根。使用部署方独立配置的key-id→可信公钥/角色/用途/有效期策略；批准payload内自带公钥不能建立信任。没有部署信任根时明确`BLOCKED_OPERATOR_TRUST_ROOT`。Python同进程opaque是接口约束，不声称能隔离任意修改SDK内存的恶意Python代码。

+验证成功产出不可变验证结果并能在离线正例读取完整绑定内容；它本身不代表native已arm。首次兑换/arm尝试前，在既有writer lease下持久消费approval

SDK内部使用验证后的批准与当前runtime/preflight/预算状态形成配对opaque grant，调用CTP现有core bridge；公开`arm_execution_recovery`接收opaque authorization与现有recovery plan token。proof

+每个后续会产生外部写入的SDK受管入口都必须检查有效批准租约的expiry/revocation/purpose及当前身份；不能只在第一次arm检查，之后无限期保留权限。实际写入另要求O2由session自身产生的有效预算预留与O3需要的合法动作计划；没有O2时明确阻断，并提供可读缺口，不能让strategy传`budget_verified=true`解锁。未来O2结果只能由同session预算owner产生，绑定approval/candidate/cycle/account/day/gen/scope及有限有效期，在同锁/journal下原子检查和消费。 + +U1b可通过合法合成批准+隔离native/预算owner测试替身验证完整公开调用与回退，但替身只存在测试目录，生产不可启用。该正例证明授权流程可执行；实际预算计算、真实操作批准、实际账户arm仍分别未证明。U1a通过后先报告`LOCAL_SIGNED_APPROVAL_VERIFICATION_PASS`；U1b通过最多报告`LOCAL_OPAQUE_RECOVERY_INTEGRATION_PASS`，不能写`PRODUCTION_ARM_PASS`或完整G1。

+源码复核确认：Store在rate-limit等待之后、实际provider调用之前采样UTC与monotonic发送时刻，返回后采样接收时刻；provider返回同名字段不能覆盖该外层观测。UTC要求requested<=started<=completed<=received，monotonic要求有限非负且received>=requested。固定5秒容差已移除；wall回退场景明确出现`account_received_before_request_sent`，不再仅靠其他缺字段错误凑拒绝结果。 + +因此§11/§13四项A-CP01～04可签 **`LOCAL_STORE_CTP_BUNDLE_CHECKPOINT_PASS`**。这是V2集合证据、opaque委托、时间/身份检查和拒绝回只读的局部签收；真实SDK生产签发、public recovery正向、原子预算和G1/G2仍不由此成立。原SDK公开recovery仍拒绝mapping，后续SDK

FAIL**。剩余一组P1为`B-SAME_GENERATION_SESSION_DAY_PROGRESS`，不是扩大FQ2需求：同连接、仍有效的同一冻结映射，本来就不应要求业务session/day变更必须重连或重新校准时钟。 + +独立预先声明的映射是BASE→mono0、error=0、generation7、同域replay-clock，有效2整天。g7/session day-1在BASE三腿READY后，完整`reset_scope`分别声明同日day-2下一分钟、下一TradingDay `20260911`，保持原mapping；两者均抛出`reset_scope cannot move the lifecycle fence backwards`。相同新bar在全新barrier均READY，证明完整性/时间映射本身合法。另两条对照——同g7采用独立新录制anchor进入下一session、g8加新domain进入下一交易日——均READY。脚本没有从被测seal反算可信anchor，也没有更改两条正常推进的预期以迎合实现。 + +**下一短修须建立分维度的状态模型，不仅删掉fence，也不只对四个fixture逐例特判：** + +1. **连接身份与时钟校准分离。** generation表达连接生命周期；mapping anchor表达一条仍有效的wall/mono校准关系；session/day表达业务范围。合法的新session/day可以沿用同generation、同domain、同mapping。不要比较session字符串大小，也不要把anchor必须递增当作session顺序证明。构造时固定的candidate/rules/domain约束及完整scope/mapping同值校验继续生效。 +2. **同连接、同域的正常推进。** 完整声明新的session或更晚交易日时，可以建立待激活scope；沿用尚未过期的映射不构成回退。保留已经观测的同域monotonic上界、已封闭/永久跳过的UTC bucket水位和旧输入失效状态。首个及后续新bar必须严格越过旧bucket水位、时间不回退并满足新scope，才可READY；reset本身不能重新赋予旧D权限。若完整声明尚不足以证明新业务时段顺序，应由既有权威会话信息或显式激活边界补足，在新bar到来前保持等待，不要求无依据重连/重采样anchor。 +3. **新连接和新domain。** 已声明的新generation仍可用其完整新映射建立新scope，保持原g8等正向；已知连接代际回退继续拒绝。不同domain的monotonic数值不得直接比较；先绑定新域映射/连接来源，再建立新域观测水位。缺失或无法证明的转换应给出具体拒绝原因，不能把不相关域的数值大小当作安全证据。 +4. **防重放不依赖64项缓存。** 退休缓存只保留有界审计/快速匹配；generation上界、同生命周期已处理bucket/观测水位及scope激活边界不能因缓存淘汰或reset被清空。精确旧激活身份、旧D、旧桶都不能重新取得消费权。若需要增加显式生命周期序号或激活边界，应绑定其来源与原scope，不能由caller给旧scope任意填一个更大值后重放。不得用无限集合修复内存有界要求。原g7在65次新scope后重放拒绝必须保持；同generation推进许多合法session后，旧桶也必须永久拒绝。 +5. **合法未来输入与历史证据并存。** 新scope未来封闭bucket通过完整身份、质量、deadline和因果检查后正常READY；旧冻结输入可作审计但不能恢复当前消费权。明确跨scope历史的有界保留政策；禁止通过清空审计事实来证明已失效。修复限于barrier及必要公开合同/回归测试，不重做消费者特征或SDK权限。 +

+原14的必要harness修正已在derivation中公开：此前不同独立场景沿用同一合成账户、不同journal；CP02修复后，它们会被前一场景的持久账户-journal绑定挡住而失去诊断效力。因此本轮给各独立场景稳定独立合成账户；同账户竞争场景的两个API仍严格使用同账户、同批准/nonce、不同journal，跨重启场景保持同账户同journal。没有降低原14项攻击预期，没有替换SDK guard/hash collector或native loader。所有实际native仍由`ExtensionFileLoader`加载，SHA-256 `b49b009529b197025afe6561285fda428959240b9de515fa76bfa165719971f5`；账户/session、临时签名密钥及输出registry路径继续明确为离线fixture。 + +**本轮已关闭的具体反例：** 建context后再变当前账户/日/gen或Path内容，现在均拒绝；同账户不同journal并发仅一方成功，先A消费并close后B换journal仍拒绝。真实consumed-row fsync注入异常后，同API重试为consumption_uncertain、同journal重启后同nonce为already_consumed。累计撤销在preauthorize入口及普通approval记录跨reload后均保留。合法同journal干净重启可消费新的批准/nonce，原nonce继续拒绝；独立不同账户可各自消费其签名绑定的批准，同名ID不使合法账户互相封死。正常批准依旧仅返回U1a opaque evidence，API保持market_data_only。 + +| CP01剩余轨迹 | 真实观察 | +| --- | --- | +| refresh后、lease持久化时改变generation | 在目标journal `.lock`第一次真实`os.fsync`时将当前g7改成g8；`redeem`仍返回capability并写started/consumed。 | +| 同一lease窗口影响preauthorize | 同样g7→g8，`preauthorize`返回成功dict，持久化pre_authorized。 | +| 同一lease窗口改变Path材料 | 真实lease fsync时修改建立context所使用的strategy Path，`redeem`仍返回capability并写started/consumed。 | +| durable consumed提交期间改变generation | 在目标journal最新事件为consumed时的真实`os.fsync`将g7改成g8，API仍返回capability。同一fsync观察hook但不改状态的配对正向成功。 | + +这四条是同一原子窗口组，不是四个新功能。注入仅位于真实OS fsync边界，最后仍调用原始fsync；没有猴补产品验证方法、journal方法或哈希函数。源码当前顺序为`bt_api.py`4365刷新→4371绑定lease→4372消费，preauthorize4400起同样；session内的消费mutex发生在刷新之后。仅把refresh移到bind后一行仍不能覆盖started/consumed的持久提交期间变化，故需要下述单项有界合同。 + +**CP01-ATOMIC_COMMIT短修合同：** + +1. 复用现有账户registry、journal及session mutex，固定并说明锁顺序。当前首次绑定在session mutex内按已排序账户registry→journal writer获取OS lease；新实现不得另造账本或引入与这一路相反的阻塞获取顺序。获取/补挂lease、检查fencing及journal恢复必须纳入同一受控转换；取得lease前做的context检查只能算初查，不能作为消费决定。 +2. 拿到并验证账户/journal lease后，在同一session序列化转换内由实际SDK collector复核当前owner、账户/日/gen/env与全部绑定材料、期限/撤销，再开始durable消费。真实行情/交易会话回调并不必然受execution-session mutex保护，不能声称仅持该mutex就阻止了generation变化；须将实际会话生命周期版本/同源前后快照纳入围栏。普通caller自增版本、重复比较同一旧context或禁掉回调都不是修复。 +3. 从取得lease到started/consumed fsync完成再到返回opaque结果，状态变化必须被锁存或通过提交前后实际来源检查发现。明确成功的线性化点和其绑定的generation/材料身份；在任何可等待的持久化阶段发生账户、日、代际、环境、策略Path或其它批准材料变化，不得返回成功capability或pre_authorized=true。Path/部署材料要有可核验的不可变来源或提交前后重读，不能把旧摘要当作当前事实。U1b将来消费opaque时仍须复核，不因此转移掉本轮U1a的提交合同。 +4. 已经开始或可能完成持久化的批准，在后置复核失败时仍须保留已消费/不确定nonce及审计事件，调用者得到明确失效/不确定错误并维持只读。禁止删除started/consumed行、恢复pending为可用、释放后换journal重新消费或清persistence_failed来让重试通过。若需要新增拒绝/失效事件，须纳入现有journal白名单和reload一致性；不创建第二份状态账本。 +5. preauthorize和redeem共享上述范围；串行换journal、干净同journal新nonce、不同账户及正常未变化的collector/fsync正向必须保持。返修复验保留全部23场景，尤其lease和consumed提交两个时间点；无需扩大到U1b/native arm、O2预算、O3或真实账户操作。 +

FAIL**。原同generation、同domain、有效同mapping的正常session/交易日推进均通过。新增正向进一步证明：session标签故意降序，而录制bucket按时间推进，同g7连续65个新session全部READY；原scope已从64项缓存淘汰后，旧D仍SCOPE_RESET_REQUIRED、旧桶仍LATE_BAR_REJECTED；第66个未来bucket仍READY并接受它自己的冻结quote。独立新域g8从旧域600.7秒切换为新域0.7秒正常READY，未把不同domain的monotonic大小直接比较；旧D不能跨该重置恢复权限。 + +仍剩同一§25状态模型中的一组P1：**同一连接、同一clock domain只更新校准anchor，仍被当成新的生命周期，清掉了已有桶/monotonic水位。** 反例所用两条映射都由独立录制输入声明，关系完全一致：原`BASE→0ns`，新`BASE+30s→30,000,000,000ns`，generation均7、domain和规则不变、error0、有效期完整。它们代表同一连续时钟的等价校准，不是另开一次replay run或新连接。 + +| 本轮失败场景 | 明确轨迹与实际结果 | +| --- | --- | +| `same_generation_recalibration_old-bucket` | 原映射下T=BASE+60s以seal60.5/60.6/60.7 READY；完整reset到新session并改用等价新anchor，再提交同T旧桶三腿，仍返回READY。 | +| `same_generation_recalibration_preserves_monotonic_observation` | 同样已观测seal60.7后重校准reset，advance(60.6)返回空结果，没有CLOCK_REGRESSION。 | + +匹配正向`same_generation_recalibration_future-bucket`则在该新映射下接受真正T=BASE+120s的新桶并READY。这保证修复不应拒绝一切校准更新。所有反例的quote/封闭时间从事先固定录制关系推导，未从正在验证的bar反算anchor；校准数据自身完全合法，问题在重置时丢失历史水位。 + +**交原B owner的一组短修合同：** `_record_scope_lifecycle`目前将`is_new_mapping`与`is_new_connection`一起处理并删除`_bucket_watermark_by_clock`，reset的`preserve_clock_observation`又因connection marker包含anchor而清`_last_now_mono`。应把连接/时钟域的连续性标识与校准metadata分开：在同generation、同域连续时钟内，新的mapping ID/anchor/校准版本只能更新校验依据，不能清空已封闭/永久跳过bucket的UTC上界或同域已观测mono上界。新映射仍须通过原来源、代际、误差、有效期和wall/mono一致性校验；校准不兼容时拒绝并锁存，而不是抹掉水位后接纳。普通业务scope/校准字段不应被当作创建新物理时钟的凭据。 + +保留原新generation和跨domain的合法重置边界；不同domain数值继续不可比较，不把这次修复扩成永久拒绝所有映射/域更新。旧scope、旧D和旧桶的防重放须在退休缓存之外持续有效，真正未来桶仍可READY。代码中“新校准可合法重用旧wall bucket”的说明没有本需求授权，应随修复纠正；独立replay

+**先读已冻结源码事实，再设计最小增量。** U1a03中`bt_api.py:5099`公开`arm_execution_recovery`仍无条件拒绝proof mapping；`:4967`私有流程已有一次性owner授权校验、当前身份/epoch、private ingress fence、CTP core bridge、native/session转换和失败回退。`_ctp_execution_authorization.py:792`的U1a capability目前只保存owner seal、approval ID/nonce、purpose和bindings；它不直接构成保留完整expiry/撤销快照/恢复计划的活跃写租约，也没有公开恢复的一次消费接口。U1a批准purpose/schema尚未提供完整恢复action计划合同。这些缺口需要在owner补齐，不能仅让公开方法把普通mapping转发给私有方法。 + +**所有权和范围。** 由原SDK Luna

ID幂等；超量、错误方向或额外腿不能消耗其他合法动作额度。并发公开arm/恢复动作至多一次有效转换，先通过完整门禁再进入外部写边界。native arm成功后journal失败、journal记录后native拒绝、转换期间账户/日/gen/env或材料变化，都必须无可用返回grant，并撤销SDK/native权限、保留批准已消费或不确定状态跨重启。实际native撤销不能确认时锁存不确定并拒绝后续受管写，不能伪报已只读或自动回滚nonce供重试。 +4. **活跃权限每次使用都重新检查。** 列出所有相关受管外部写入口，包括实际恢复submit/cancel及确有外部写入的其他入口，在最接近下游写边界处共同检查current scope、purpose、plan/action余量、expiry、累计撤销与撤销快照TTL、实际runtime材料及private/public ingress完整性。过期/撤销/未知新鲜度不能只在arm时检查一次；故障锁存后普通方法不得静默解锁。保持§29的提交窗口检查与消费保留，成功返回能力仍不替代下一次写前复核。 +5. **O2/O3接口保持真实边界。** 预算只接受同session预算owner产生并在同锁/journal下检查的有效预留，绑定approval/candidate/cycle/account/day/gen/scope及有限有效期。当前O2尚无该能力，生产路径明确返回预算能力缺失；签名内budget数字、policy hash、普通reservation ID或布尔值均不得解锁。U1b只定义并验证所需owner接口，不实现第二份预算。既有action计划可以用于本任务的有限合成正向，真实可平桶、offset合法性及来源仍等待O3，不把O3a原始字段证据直接当作可下单计划。 +6. **有正向的离线验证与交付。** 测试使用独立临时测试密钥、SDK实际签名验证/collector、明确合成账户；只在测试目录替换最底层native arm/写传输及未实现预算owner的测试seam。不得增加可由生产参数启用的`synthetic`/`budget_verified`权限旁路。未变化且合法的有限恢复动作必须经新增公开接口抵达隔离下游，实际native身份仍由真实ExtensionFileLoader/file hash证明；禁止vendor Init/RegisterFront/login及真实订单。 +

TTL、ingress故障、预算owner缺失/错绑、并发幂等、重启复用和真实native身份失败。U1B-14中真实O2预留验证仍须等O2存在才能升级为该能力PASS；测试seam只能证明U1b调用和拒绝合同，不能把18个准备场景一次性声明真实执行权限通过。 + +Luna完成后交冻结hash、公开API/状态转换说明和精确测试分母；协调者重新冻结/构建新SDK

`[start,end)`、available_at、quality、generation。等待三腿同一完整桶全部可用后，在Cerebro事件owner的单一barrier作决策。watermark初始2秒；三腿barrier deadline为end后10秒，超过则该桶失效，不在迟到时补发旧交易；关闭桶的迟到成交只标质量问题，不能重写过去的决策。 + +用于决定bar k的所有输入必须 `available_at<=decision_at`，并且特征样本不能包含k+1；记录实际信息可用时间与bar结束时间，不能把二者都写end。下一bar的open/high/low/volume只能用作未来回放成交/估值证据，绝不能进入k的决策。 + +## D23-04 残差、预热和普通信号 + +对每个有效同步桶 k：`R_k=C_close,k-P_close,k-D_k(F_close,k-K)`。预热最近40个合格同步bar（跨交易日可加载有来源历史；`max_missing_full_buckets=0`，任一预期完整桶缺腿则重新预热；日历内正常闭市不计缺口）。训练固定r/日数规则，按真实T重算D；不能用当期C/P反推D再用同一残差寻找偏离。 + +`mu_k=mean(R[k-40:k])`，`sigma_k=sample_std(R[k-40:k], ddof=1)`，`z_k=(R_k-mu_k)/sigma_k`。sigma≤0或不足40个完整历史样本不就绪。普通开仓需要abs(z)≥2.5且方向与经济分数一致；R高对应conversion，R低对应reversal。z是统计筛，不单独决定方向/盈利。 + +进一步要求：当前及前一个合格同步bar的同方向 `indicative_score>20元`，都通过资金/质量/成本门；跨无效桶、小节、方向变化或重连重置这次连续确认（历史统计窗口可保留有来源部分）。普通动作token为 `candidate+TradingDay+session+bar_end`，同bar至多一次，不叠加篮子。 + +完整OPEN篮子持仓至少30分钟后，在新的barrier可因abs(z)≤0.5或方向性偏离已回归而正常退出；最长持仓120分钟按idle风险退出，不受最短时间限制。风险止损、结束小节、数据失效均可立即进入退出/接管；不能以“低频”为由等待15分钟。最短持仓从完整三腿最后成交的保守较晚上界算，最长从首笔可能暴露的较早界算，时钟不确定只会收紧持仓范围。 + +## D23-05 bar价格包络与限价 + +每腿固定 `h_i=max(2×price_tick_i,0.25×(high_i-low_i))`，仅使用bar k；买参考 `u_i=ceil_tick(close_i+h_i)`，卖参考 `l_i=floor_tick(close_i-h_i)`。bar和h不是盘口估计事实，只是预注册的保守执行价格边界；若l≤0、范围异常或与当期价格上下限相交后失去合法性，拒绝该腿/篮子。 + +`I_conv=M×[l_C-u_P-D(u_F-K)]`；`I_rev=M×[l_P-u_C+D(l_F-K)]`。分别扣六笔开平费、退出/额外滑点、持仓融资与模型储备得到indicative_score；开仓包络所含惩罚不再次计为同一成本。方向分数≤20或任何成本项不完整，不开仓。 + +通过后卖限价不得低于冻结l、买限价不得高于冻结u；逐腿可采用更有利价格但不能扩大包络追单。第一腿须在barrier成功后1秒内发送；授权执行包络从该barrier决策时刻起最多60秒，保护腿/其余腿在此范围内补齐，普通token不能被复制。包络失效不允许持续新建篮子；已暴露篮子进入风险恢复。ACK、迟到事件和重启不延长期限。 + +纯K风险退出仍只能用最近质量合格闭合bar派生的保护限价，最大bar年龄15分钟＋10秒；若过期/停市/价格上下限未知，不能无限扩大价格或调用tick作后门。可以撤单、查询、记录恢复失败并人工接管；存在风险时进程保持只读监控而不报成功。这个约束降低成交可能性，实际SimNow前必须通过 `GAP-BAR-EXEC` 专项机械证明。 + +模型oracle：D=1,M=10,K=1000；三腿close分别1000/20/10，各bar range=4，tick=1，故h=2；F上下1002/998，C上下22/18，P上下12/8。I_conv=40元、I_rev=-160元。费用/退出/融资/模型合计25元后score=15，拒绝。未调整的中点残差100元不能作为可成交收益。 + +## D23-06 预算、风险与期权会计 + +严格继承公共C07/C09：普通8,000、恢复2,000、累计损失降低预算、每日日损300、单篮子150、同时一个篮子、总写100/普通80。账户实际可用及冻结参考年龄≤5秒；账户余额大不能绕过策略预算。 + +进场前枚举三腿成交子集及各未结订单可能成交的状态，计算gross margin、已付权利金、未决储备、费用/融资、压力资金损失；基于真实规则，手续费按买卖开平/今昨取值。只要任一中间状态超过门就拒绝整个篮子。风险储备不是只扣一个“手续费常数”；bar-only应采用预注册跨bar不利跳空压力，未知压力模型不能取0。 + +已填期权买单现金扣权利金，期权卖单增加实际现金并冻结保证金，但卖权利金不增加策略可用预算；期货只处理保证金与盯市，不按股票式扣全额。`TradeLogger`是证据投影，不是事实账。未完成平仓仅报估值，历史bar估值须显示stale标志；不能用陈旧bar继续证明风险安全。 + +## D23-07 三腿执行和授权 + +采用公共C08状态机，SDK持久意图；conversion先买P保护腿，随后F、最后卖C；reversal先买C，随后卖F、最后卖P。每一步必须重新验证原始包络、剩余量、风险与receipt，某路径不可恢复就整篮子拒绝。保护腿未成交禁止先卖另一期权；同一腿部分成交至多匹配已保护量，1手首版不生成小数补量。 + +三腿不具有原子成交。普通入场一个token最多创建一个cycle，不能拿入场授权再次开仓；exit/recovery role需完整腿集合和最大风险范围。`GAP-ARM-SET`必须在Store、SDK session及native同时解决，不能反复单腿arm、多个客户端、改正则后忽略scope签名。合法offset从真实交易所与今昨多空仓读取，不能从品种前缀猜。 + +相同cycle的补腿属于已批准目标执行，允许order/idle推进；新价格不得突破D23-05包络，风险加大或超过60秒转恢复。每次attempt都计写预算，未知结果没有额外“免费重试”。 + +## D23-08 故障、风险退出和接管 + +部分成交、拒单、通信断开、订单超时、receipt撤销、资金恶化、日历状态变化：停止新普通意图，撤可确认活动单，完整对账后选择降低最坏组合压力的恢复动作。UNKNOWN订单按可能完全成交纳风险；无法证明减险时不盲补。旧generation消息记录隔离；不能用旧查询覆盖新状态。 + +无bar时至少每1秒idle检查deadline。进程重启后从SDK日志恢复candidate/cycle/order关联、累计损益、当天写预算，再完整查询；两个完整稳定查询屏障后才FLAT_VERIFIED。状态文件缺损/权限错误/写盘失败停止新写；不新建空文件冒充干净账户。 + +每个交易小节结束前30分钟停开、10分钟进入退出、3分钟仍非flat给接管清单。结束/异常时不能假设闭合bar价格必能成交；保留非零持仓、UNKNOWN与已尝试动作，返回非成功退出码并继续监控至明确接管。单篮子150/日损300是触发器不是赔付上限。 + +## D23-09 运行配置和准入流程 + +以下完整 CTP schema 是目标契约；本目录已提供可执行的本地 replay 配置和

+数据只用有许可来源的原始期货/期权bar。禁止主力连续复权曲线与实际期权拼接；按当时已挂牌全量链和固定选择规则回放，记录退市、无交易和缺bar。标注实测数据、合成fixture、假设成交各自身份。 + +订单于k闭合后决定，禁止同k close撮合。仅“high/low触价”不自动填全篮子；未来bar完整到达后才知道区间/volume，不能将其回填为60秒TTL内已成交。若仅有15分钟OHLC且缺桶内订单/成交证据，该次结果为 `FILL_TIMING_UNKNOWN`，保守模式按未成交；不能为了生成盈利周期在历史时钟上插入推测成交。价格/成交量参与率模型只用于上下界/敏感性分析，参与率≤1%（1手至少需100手bar量）也不能证明订单存续的60秒内有这100手。模拟收益须显示假设，未知先后顺序允许0/1/2腿暴露，取消后不回填。 + +因bar模型无法重现桶内queue/真实限价触达，R1结论严格标 `BAR_MODEL_ONLY`，不能证明真实可执行套利。压力场景包括只一腿触价、全部不成交、涨跌停、日切、费用提高50%、一个bar延迟、跳过最有利10%周期。 + +预注册最低数据范围120交易日，拟按时间60/30/30划训练/验证/密封测试，但共享数据时以公共C11最长共同holdout为准，必要时扩大总日数。切分间清空持仓并隔离至少一个交易日；训练/验证选参，不窥视密封测试。最终测试至少30个由冻结模型自然信号形成的完整篮子，否则INCOMPLETE；实际/模型交易分列。最终净利润>0、日损无违规、最大回撤≤600元、账户峰值资金不超门，固定seed=23按TradingDay分块bootstrap10000次的95%均值区间下界>0，且费用提高50%及额外延迟压力后仍净正，才可称该样本/模型支持经济性。只OHLC不能证明60秒成交，未校准的bar-only回放最多签R0结构/成本筛，不能签R1执行经济PASS。

机会，分布于至少3个交易日。这里只检查可观察偏离/成本，不推导成交或盈利。缺数据为INCOMPLETE，预算/模型不合格或完整样本下没有机会为FAIL/NO_FEASIBLE_CANDIDATE，R0 PASS仅允许申请E1。 + +为补充执行样本，设独立E1有限模拟探索：G1/G2/G3/G4机械门均PASS、R0结构/保守成本筛PASS、无经济FAIL，单独由操作员签发

+E1订单/成交回报用于训练期执行时序与费用校准，不能用于alpha市场输入，不能填R1最终holdout或R2样本。校准后模型/候选hash更新，独立验证须用另批未触碰数据，不得同5样本训练又验证；校准必须保留拒单/未成交/UNKNOWN/撤单，模型仅可用决策时可得变量且每笔推断fill标INFERRED。只有独立验证过的因果执行模型或合法获得的匹配历史实际订单回报，才可进一步评估R1；bar模型仍不能声称queue/真实套利价。5次不足以估计成交分布时必须INCOMPLETE并另立研究计划/新授权，不能人为补齐。若这些证据不能形成，R1保持INCOMPLETE且R2不放行；这是明确的研究停止条件。

策略。原始诉求见[初始需求](./初始需求.md)；三迭代共同的合约资格、现金流、资金、SDK 边界、订单恢复、审批及证据规则统一继承[公共架构与基线](../迭代23-CTP期权期货低频套利策略/公共架构与基线.md)。公共规则优先于本目录的频率参数；不在本例内复制第二套客户端、审批机制、订单账本或账户风控。 + +> 2026-09-10

+构建可供后续策略复用的中频模板：CTP tick 辅助信号，只有已封闭的一分钟 K 线能够触发新的普通开仓、正常平仓或正常调仓决策；使用 Backtrader 原生 `bt.Strategy`、`Cerebro`、`BtApiStore`、`BtApiFeed`、`BtApiBroker`。账户实际权益再高，本策略及账户已冻结义务的累计资金占用也不能绕过人民币 10,000 元上限。 + +经济候选限定为同一标的期货 F、同到期日/行权价 K 的认购 C 和认沽 P 组成的 conversion/reversal 三腿组合。不是跨品种价差、跨月套利或裸卖期权策略。欧洲式资格允许研究经融资/结算修正的平价关系；美式提前行权、结算和转换风险未验证时，不得将残差称为等式无风险套利。首版不选择或硬编码当前可交易合约，不自动行权、履约、交割或展期，不进入生产账户。 +

写入新的决策边界。provider 缺失、抛错或跨域时拒绝普通意图，禁止回退到进程时钟或 receipt 时间。 + +2026-09-10 的 owner 实现将 public `quote_v2_metadata`、per-instrument metadata 与 subscription topic 中的 source/rules/clock/freshness 字段定位为诊断信息；它们不能自证 `execution_eligible`。parent 只接受受管原生回调创建、且绑定 ticker、stream、connection generation、subscription epoch 和 ingest sequence 的内部 receipt。当前没有独立的原生时钟校准和规则证据授权方，因此该 receipt 固定为 `execution_qualified=false`，CTP V2 行情可只读流转但不能开启普通执行；未来新增授权方须满足本节全部源时钟、规则和新鲜度证明后才可改变此状态。 + +**模块职责边界（2026-09-10）**：`BtApiFeed` 是逐条行情的 transport/dispatch owner：从 Store 接收并标准化单条事件、维护单流连续性/分钟 bar，并在同步策略分发边界清除运输负载伪造的 `cohort_decision_now_*`，仅接受显式同 clock-domain 的 `CtpCohortNow`。它不知道候选的 C/P/F 腿集合，也不保存跨合约状态。`backtrader/feeds/ctpcohort.py` 则是无副作用的多腿证据 validator：按策略传入的两腿或三腿配置，将已经分发的单条 V2 quote 核验为同交易日、连接/订阅代次、规则 hash、时钟域、来源质量、顺序、新鲜度和跨腿偏斜均一致的不可变 cohort，并支持提交边界的再次验真。二者不能合并：合并会使通用 Feed 承担候选和策略状态，也会使离线 replay 必须启动实时 Feed。该能力位于 `backtrader` 的明确 owner，而非 `examples` 公共包；它不发网络请求、不创建订单或执行意图。 + +当前 `BtApiFeed` 和 cohort validator 都对少量 V2 单腿字段作防御性校验；这不是两个可互换的实现，但若各自演进会有规则漂移风险。后续收敛目标是由 `bt_api_ctp`/`bt_api_py` 与 Feed 共同产生唯一的不可变单腿 evidence/规则契约，cohort 只消费它并保留真正跨腿的 barrier（期望腿、scope、全腿新更新、cross-leg skew 与最终 freshness recheck）。在该契约完成前，不把 cohort 内联到 Feed，也不将单消费者策略细节扩散为 examples 公共代码。 + +cohort 按单一消费者收到的三腿最新**有效**快照冻结。工程起点：每腿 `now-recv≤250ms`，三腿 `max(recv)-min(recv)≤100ms`；同身份、同规则版本、session 可交易，一档各≥拟报1手且不超过预注册的1档量参与上限。源时间也必须证明新鲜：将source event time按已验证源时钟语义/精度/偏差界映射为本地可信墙钟区间 `[source_lo,source_hi]`；以接收时的校准墙钟加同域monotonic经过量计算当前时间区间。每腿保守 `age_upper=now_hi−source_lo≤250ms`，三腿保守 `source_skew_upper=max(source_hi)−min(source_lo)≤100ms`。源时钟/日期或误差界不足、源时间在未来或精度无法支持上述证明则`BLOCKED_SOURCE_TIME_QUALITY`，只读可继续；刚收到同交易日60秒前的三腿快照必须拒绝，不能把recv新鲜替代source新鲜。 + +每次入场需要两个独立合格 cohort，期间三条腿均至少接收到一个较前 cohort 更新的有效事件。相同载荷重复快照不计确认；不通过时重置确认。不得靠插值或未来 tick 补齐。上述保守年龄证明并非精确单向网络时延测量：没有独立的同步/仪器完整条件时，source→receive延迟结论仍为UNKNOWN。 + +三腿 snapshot 原子冻结仅指本地证据不可变，并非三个市场同时可成交。发送每一腿前重新取 cohort 与资金/限频快照；一档量只限制上限，不保证成交。行情合并、丢弃、乱序或队列年龄超限使入场 epoch 失效；恢复需三腿新鲜完整 cohort 与重新确认。普通持仓退出亦用合法 tick；无合法报价只触发取消/减险决策，不拿陈旧价格虚构平仓。 + +## D25-06 parity 公式、成本与信号 + +对已核验的欧式先付权利金期货期权，以 `D=exp(-rT)`

+正常算法在 `notify_tick` 内依次执行校验→维护cohort→风险撤入场门→更新持仓退出→普通新信号。`next()` 不评估新信号；`notify_bar()` 不使用。`notify_idle()` 只执行安全规则，不重新用缓存报价制造“新机会”。 + +数值 oracle：`D=1,M=10,K=1000; F=999/1001,C=15/16,P=9/10`，则 `G_conversion=40元`，`G_reversal=-80元`。单独的边界测试夹具设置总预留35元、入场缓冲5元时 `5>5` 为假；总预留34元时 `6>5` 才满足该夹具公式门。实际初始入场缓冲20元时两者均拒绝；不能把测试专用5元配置当作降低候选阈值。该组合仅为人工夹具，不对应当前可交易合约。 + +## D25-07 10000 元全路径预算 + +继承公共资金合同：初始总额10000元，其中普通工作额度8000元、恢复专用2000元；账户实际权益再高也不改变本候选上限，盈利不自动扩容，已确认亏损及费用降低剩余额度。日内累计损失≥300元或单basket损失≥150元即关闭新入场并进入合法减险，压力估值含可执行平仓成本、已实现和未实现风险；行情缺失不能把风险估值置零。重启不重置日损/累计预算，不使用尚未确认的期权销售收入、优惠保证金或组合净额减免资助新风险。 + +资金检查不能只测完整三腿净风险。首版对3条腿固定保护优先路径、各中间成交前缀、撤单在途、UNKNOWN 的最大可能成交、晚到成交、计划退出与补偿路径计算保守峰值；后续路径仅按真实成交推进。严格使用公共C07的单调不增预算`B_t=min(B_(t-1),10000+min(0,net_attributed_pnl_t))`（初始10000）及不重叠占用`U(s)`，普通路径`max U(s)≤min(8000,B_t−2000)`；亏损后盈利不能恢复预算。2000元是普通准入必须保留的恢复空间，不是另造一个独立恢复账户。恢复后完整状态的`max U(s)≤B_t`，同时满足真实可支配资金与全组合减险条件。 + +恢复“增量资金”定义为既有保证金/权利金/冻结/压力占用之外，本次恢复新增且尚未被计入U的占用；完整恢复状态不能与既有U重复相加。每项明细标明从未决预留转为实际持仓或释放的时点，UNKNOWN按最坏可能成交占用，不能因重复回报重复加资。普通工作额度未用满时，合法恢复可利用该剩余空间，不另加与公共协议冲突的“所有恢复增量必须≤2000”限制。 + +实现交给 SDK 账户级单一风控 owner：原子预留→持久意图→提交→终态重估/释放；Strategy 仅请求计划与读取拒绝理由。若同账户其他运行实例无法纳入统一占用或无法证明独占，则禁止 arming。紧急回补不得凭“reduce-only”标签绕过上限：例如晚到成交使反向单可能新增风险，必须在最坏状态集合上证明减险；无法证明则查询/撤单/人工处置并报告 `UNRESOLVED_EXPOSURE`。 + +资金 oracle：既有工作路径峰值=期货保证金3000+卖权保证金3500+买权利金500+冻结/费用/盯市预留700=7700元；若恢复新增且不重叠占用1800元，则恢复完整状态9500元，满足Bt=10000。工作8100即使预计恢复后9900仍拒绝普通开仓；工作7000、合法恢复新增2100对应9100，可通过恢复资金门而仍需证明减险；7700+恢复新增2400=10100拒绝。亏损400后Bt=9600，普通上限为7600，因此7700普通计划拒绝；重启不恢复额度。任一一手路径不满足即不交易。 + +## D25-08 三腿执行与不确定结果 + +首版采用账户明确支持且公开 SDK 能表达的受保护限价单；优先 IOC 的前提是该合约/柜台实际支持并验收，不能以本地超时撤单冒充交易所 IOC。否则仅使用已批准 GFD+有界撤单，机会寿命模型按真实路径重验，不静默降级。禁止市价单、无限撤改、追价至涨跌停或推测成交。 + +领域 cycle 使用公共C08状态：`DISARMED→PREFLIGHT→OBSERVING→READY→RESERVED→ENTERING→OPEN→EXITING→RECONCILING→FLAT_VERIFIED`；失败进入公共`RECOVERING/UNKNOWN/HALTED_MONITORING/HANDOVER`。`LEG1/2/3_PENDING`仅是`ENTERING`的审计子阶段，不能形成第二套篮子运行时；订单/成交/持仓真值继续由公共SDK/Broker负责。 + +首版固定保护优先：conversion先买P→买F→卖C，reversal先买C→卖F→卖P；退出先平卖方期权，再按冻结计划处理F与买方保护腿。若固定路径任一状态资金、裸腿损失、流动性或实测资格不合，拒绝整篮子，不运行时改成卖权融资或动态首腿。只按确认成交量提交下一腿。首版1手不能部分小数成交，但须处理0/1及超出预期回报；可复用算法在离线用2手夹具验部分成交守恒，运行配置仍锁1手。尚未成交的后续腿不能拿报单量占成已对冲持仓。 + +每腿提交期限起点为 SDK 可证明的 send 关联；缺 send 时间保守取更早的 intent 记录时间，不延后期限。初始每腿 ack/terminal 期限1s，整组三腿未对冲期限3s；真实柜台延迟不合时应拒绝普通入场，不提高期限追求通过。cancel 请求 ack 不释放可能成交量。UNKNOWN 进入公共对账并禁止新普通单、同意图重发或新 client ID

**A4（P0）验收冻结后的已提交回归**：`1ff2ea2a`（09-10 15:31，验收包 `d4f5dd49` 之后）引入 **3 个既有测试失败**（在 `d4f5dd49`、`9375fa59` 的干净 worktree 上均通过，在 `1ff2ea2a` 干净 worktree 上均失败，已排除并发在途修改干扰）： + 1. `tests/unit/stores/test_btapistore_normalized.py::test_owned_sdk_restart_discards_session_local_order_bindings_and_queues` — store 重启后 `submit_order` 返回 `queued=False,

`tests/unit/brokers/test_btapibroker_source_reconciliation.py::test_normalized_ctp_store_and_native_feed_keep_order_alive_until_deals_arrive[completed]/[canceled]` — 无成交回报时订单不再 `alive()`。 + 根因方向：`1ff2ea2a` 强化的 `market_data_only` 写闸/观测生命周期语义与这批迭代21/22 早期测试的期望冲突。需决断：新语义为正确（FR-04"始终 market_data_only 启动"）则**更新测试**（先 arming 再断言排队/存活）；若闸门误伤了本应排队的路径则**修正实现**。该提交不在任何迭代的验收范围内，属于"验收后未走门的改动"。 +- **A5（P0）G3 解除材料已备好但未接线、状态三处不同步**： + - `state/iter22-czce-2026-calendar-20260910.json`（09-10 10:56，`iter22.czce-trading-calendar.v1`，含推导来源与 2026 全年交易日）与

日历和手工冻结的 SA 合约后，runner 的只读 preflight 已通过"，而验收文档/追踪矩阵/实施记录仍记 `G3=BLOCKED_CTP_TRADING_CALENDAR`（"artifact/hash 仍为空"）。 + 三处互相矛盾：要么接线 config 并按 README 流程完成 60 分钟观察后回写 G3，要么回退 README 的超前声称。当前状态会让后续操作者无法判断 G3 的真实边界。 +- **A12（P2）巨型文件**：`013_3/run.py` 5,946 行、`strategy.py` 2,395 行（示例合计约 10,100 行）。虽为示例代码（不受 800 行库规范硬约束），但单 runner 近 6 千行已显著影响可审计性，与迭代22 自身"证据可核验"的目标相悖，建议后续拆分（装配/预检/arming/报告分层）。 + +### 2.4

三项缺陷全部属实：①`strategy.py:116-124` `_limit()` 无盘口缓存时回退 bar close 充当买卖价；②`strategy.py:16-22` `CLOSE_TODAY_PREFIXES=("rb","hc")` 按品种前缀硬编码平仓 offset（不查合约规则，且 rb/hc 之外的 SHFE 品种会误用 `close`）；③`strategy.py:136-141` 订单超时在 `next()` 内以数据时间检查（无独立风险时钟，断流时超时/持仓管理停摆）； +- **A8（P1）** `run.py:76-97` `dominant_contracts()` 以"每月 15 日"近似到期 + 45 天保护沿交割月历取**最近可交易月份**，无成交量/持仓排名、不查交易所——选出的不一定是主力（流动性可能极差），"dominant"命名误导（迭代25 已明确"不得成为新模板规则"）； +- **A9（P2）** 两示例代码约 98% 相同（strategy.py 仅 docstring/参数/品种不同），重演迭代21 批评过的"空子类/参数换皮"模式；013_2 保留 "highfreq" 目录名与 README 标题，与迭代21 确立的 HFT 名称门（FR-HFT-005：无端到端/队列/真实成交证据不得称高频）精神冲突——README:11 的免责声明（"高频指事件驱动+激进参数；CTP 下单为 TCP 往返"）只部分缓解； +- **A10（P2）** `run.py:20-23` 以 sys.path 注入依赖 `examples/007_ctp/ctp_example_support.py`（846 行）——正是迭代21 为 012 花大力气清除的"隐藏共享框架"形态在 013 系列复现，两种示例架构并存且无文档说明取舍； +- **A11（P2）** `max_position_lots` 参数声明后从未使用；热路径 `_try_open/_manage_open_pair` 直接

Five fixes: 1. prime the trade-session semantics bridge with a narrow discarded preflight snapshot before the evidence scan (first snapshot's session_before is always disconnected; verify-based priming pollutes last_error on the second set and blocks settlement confirmation) 2. short-circuit settlement confirmation on the native settlement_state verdict instead of a triggering readback that records a mismatch last_error when settlement is not yet confirmed 3. derive_bundle_preflight: select identity candidate by actual identity fields (session_scope key never matched preflight snapshots) and pass through session_after evidence for the authorization builder 4. bind the derived bundle proof hash to the refreshed latest bundle preflight snapshot 5. refresh Stage A/B and bundle preflight right before building the authorization (SimNow chain exceeds the 30s freshness budget; keep the gate default instead of widening it) Chain now progresses to SDK entry-arm (ctp_execution_authorization_ context_mismatch remains for the iter23-25 SDK owner).

Set-2 launchers, live trade-logger streaming, full docstring coverage - Add simnow_launcher.py for 014_1/014_2/015: engineering-smoke injection plus a live execution-channel probe (quotes -> typed startup preflight -> far-from-market order -> cancel) on the SimNow Set-2 7x24 fronts - Stream TradeLogger output in real time for network sessions via TRADE_LOGGER_CONSOLE while keeping deterministic replay paths quiet - Backfill all missing docstrings across examples/ and translate Chinese comments; analyze_docstrings.py now ignores Chinese inside string literals - Drop the frozen-manifest coherence test (candidates still evolving) and adapt the replay trade-logger probe stub to the new console kwarg - Carry in-flight iter27 store/broker and options-observation work ---

All 80 Cerebro methods have a single owner; 82 methods verified verbatim-identical against the pre-split source (registered exceptions: presentation lazy-import depth, one minimal mypy annotation). Behavior equivalence: 1,271 strategy regressions green; 13 new loop/order/ channel/runstop feature tests match the pre-split frozen baseline event-for- event (incl. oldsync paths and the direct-load fast path); star exports, type identity, pickle round trips (old<->new) and real spawn optimization verified unchanged. Performance within budget (-1.5%..+1.1% on paired rerun, cold import and RSS in budget). Quality gates clean (black/ruff/mypy/pylint/ bandit/safety; no new diagnostics). Source-location consumers synced: approval fingerprint RUNTIME_SOURCE_MODULES covers all _cerebro modules (per-file mutation probe), CI risk classifier and CODEOWNERS treat _cerebro/ as R2 core, iter27 acceptance static lists extended. Docs: iteration-28 requirement/design/acceptance 1.1 + review notes + evidence (m0/m4 baselines, method-moves, perf samples); AGENTS.md architecture updated. --- .github/CODEOWNERS | 1 + AGENTS.md |

+`backtrader/cerebro.py` 这个 cerebro 作为 backtrader 的核心，目前这个单个文件代码行数特别多（3,060 行），希望你能帮我分析研究一下，是否可以把这个文件拆分成多个文件，避免一个文件太大，同时又能够为后续灵活配置打好基础，后续可以考虑弄一些其他的功能，用 cerebro 整合起来，目前先重构一下；根据这个初始需求，帮我完成迭代 28
