Backtest Checker

Paste your strategy code or description to check for common backtesting red flags.

Currently uses deterministic heuristics. LLM-powered analysis coming soon.

This tool flags common backtest pitfalls in the code you paste. The check runs in your browser. It does not judge whether a strategy is good, and a clean result does not mean a strategy will work. Not investment advice. Provided "as is". Terms & Disclaimer
