// why we built it
ML signal engines for trading don't require a hedge fund infrastructure team. A well-engineered Python package with the right architecture can be built, maintained, and extended by a single practitioner — and released as open source without compromising the core thesis. The ensemble architecture and SHAP explainability are what make AlphaStream a practitioner tool, not a toy.
// what it does
- 200+ technical indicators computed via TA-Lib, pandas, and custom implementations
- 5 ML models per instrument/timeframe: XGBoost (primary), LightGBM (speed-optimized), Random Forest (confidence calibration), Ridge Regression (trend baseline), Ensemble Voter (learned weights)
- Backtesting engine with walk-forward validation and held-out test sets — no look-ahead bias
- SHAP value explainability: every signal maps to contributing features with importance scores
- Clean CLI and programmatic Python API with full documentation and strategy examples

Most algorithmic trading signal tools are black boxes — output with no visibility into why a signal fired, what inputs drove it, or how it performed historically. For practitioners, that's not a tool. It's a guess with a UI.
