Live site not publicly available
Under client confidentiality agreements, we can't share the live URL for this project. We'd be glad to walk you through a live, similar demo in a meeting — let's set one up.
Overview
A production-ready algorithmic stock trading platform built from the ground up. It processes live market data in real time, executes SMA/EMA crossover strategies, and provides P&L tracking, trade history, order management, backtesting and cycle reporting — running real trades on Bank Nifty options.
What we did
- Built the full backend in FastAPI with REST + WebSocket endpoints for live data, trade execution and strategy management.
- Designed a scalable MongoDB schema for high-frequency tick-by-tick data.
- Added Redis caching, cutting average API response time 40% (220ms → 130ms).
- Real-time WebSocket streaming with sub-second updates to many concurrent clients.
- Admin panel: Pair / Auto / Repeat Backtest and Option Strategy modules.
- Automated daily market-data archival to AWS S3, Excel export and a Pytest test suite.
