Free backtesting tool that detects luck-based trading strategies
Verax is a free backtesting tool that stress-tests trading strategies across multiple market regimes, performs parameter sensitivity analysis, and provides honest verdicts on whether a strategy outperforms buy-and-hold. It includes a bar-replay game where users paper trade historical data and compare results to holding. The tool uses LLMs to generate natural-language explanations of strategy performance and market pulse signals.
