Stock Explosion Detection System – ML-based Breakout Engine
https://patternrank.io/This is a large-scale research platform I built to detect high-momentum breakout opportunities in US/Indian equity markets using machine learning and engineered signals. The system processes over a decade of historical market data and generates predictions using stacked ensembles composed of XGBoost, LightGBM, and meta-models.
I designed deterministic walk-forward backtests spanning 940+ days per split to ensure realistic simulation and robust generalization. The platform includes 80+ engineered indicators, feature pipelines, and automated data ingestion.
The project also experiments with reinforcement-learning-style open-ended learning loops—allowing the system to adapt to shifting market regimes over time. The back-end infrastructure uses Supabase PostgreSQL and Redis, with Python as the core modeling engine.
This ongoing research effort blends engineering, data science, and quantitative modeling into a production-grade experimentation environment.
