# backtest-reality-check

> backtest-reality-check — maximdakulinin-boop-backtest-reality-check. Use this tool when you need to validate the reliability of a trading backtest by assessing its statistical significance and robustness. It solves problems of overestimation and false confidence in trading strategies by applying deflated Sharpe ratio, multiple-testing correction, and fill realism checks. This tool takes a trading backtest as input and outputs a reality check report, helping you determine when a strategy's performance is weaker than claimed or not yet provable.

## Description

Checks whether a trading backtest survives its own statistics: deflated Sharpe, multiple-testing correction against a best-of-N-noise benchmark, minimum track record length, and fill realism. Takes no market data and no API keys, and cannot recommend a trade — it only reports that a result is weaker than claimed or not yet provable.
