 **project-x-py** is a high-performance **async Python SDK** for the [ProjectX Trading Platform](https://www.projectx.com/) Gateway API. This library enables developers to build sophisticated trading strategies and applications by providing comprehensive async access to futures trading operations, real-time market data, Level 2 orderbook analysis, and 64 named indicators (Polars implementations; **not** a full TA-Lib port).
