Strategy Robustness Backtester
A desktop/web app that helps retail traders evaluate whether a strategy is robust by running walk-forward tests, regime splits (trend/mean-revert/volatility), and stability diagnostics instead of single-period backtests. It focuses on answering practical questions like "does this edge persist across months?" and "is the trade frequency high enough to be viable with my rules?" without providing trade signals or investment advice.

Strategy Robustness Backtester
A desktop/web app that helps retail traders evaluate whether a strategy is robust by running walk-forward tests, regime splits (trend/mean-revert/volatility), and stability diagnostics instead of single-period backtests. It focuses on answering practical questions like "does this edge persist across months?" and "is the trade frequency high enough to be viable with my rules?" without providing trade signals or investment advice.
Target customer
Serious retail day traders and prop-firm aspirants who already backtest (or want to) and need a more objective way to validate strategies and avoid wasting months on unstable setups.
Problem-solution fit
Users are stuck because naive backtests look good in one month and fail in another, and subjective strategies are hard to test consistently. This product turns strategy evaluation into a repeatable workflow: define rules, run multi-period robustness checks, quantify trade frequency and drawdown behavior, and output a go/no-go report with clear failure reasons (overfit, regime dependence, insufficient sample size).
