PatternsRadar
Indian stock screener with 30-year backtests and MCP
Free NSE stock screener. Build scans with clickable blocks or a typed query, then replay them over 30 years of split-adjusted data to see what the matches did next. Screen on delivery %, F&O open interest and point-in-time fundamentals. API + MCP included.
Hey Product Hunt 👋
I built PatternsRadar because every Indian stock screener I tried let me find stocks, but never told me whether the setup had ever actually worked.
So here's what it does:
🔍 Describe a setup with clickable blocks or a typed query. They're the same query, so you can switch mid-thought.
⏪ Replay any scan across 30 years of split-adjusted NSE data (back to 1995). You get win rate, median move and excess over the index, and it comes back in about 100ms.
📦 Screen on things others skip: delivery %, futures OI and basis, and fundamentals valued as of the scan date, so there's no look-ahead.
🤖 API + MCP server on every plan, including Free. Point Claude Code or Codex at it and the agent writes and runs scans itself.
What it won't do (better you know now): no intraday, NSE only, and the replay doesn't model brokerage or slippage.
Screening and backtesting are free, with no signup needed. Paid plans add end-of-day email alerts and webhooks.
I'd love to know which scan you'd replay first, and what's missing. I'll be here all day answering questions.
