StrategyFalsifier

The standard falsification report plus: cost sensitivity extended to x10 your assumed fee, data refresh and one re-run within 7 days, and a 30-minute recorded walkthrough of what the numbers mean for your strategy. Same rules: no signals, no subscriptions, no managed capital, no return promises.

I try to KILL your trading strategy and print the evidence. You get a markdown + JSON report covering: (1) path-aware replay, bars walked not sampled, a bar containing both stop and target resolves to the stop by default with the optimistic read alongside; (2) cost sensitivity at 1x/2x/5x your assumed fee; (3) barrier reachability: are your TP/SL levels prices the market actually visits inside the hold window; (4) random-entry control group with bootstrap CI on the difference. Verdict comes from falsification rules declared before any number is read. Open-source engine (MIT, 38 tests), offline replay. Deliverables: report + raw JSON.
