Does the strategy have edge, or did it overfit the past? We review backtest robustness — overfitting, fragility, drawdown, Monte Carlo and out-of-sample behaviour — and return a defensible verdict.
A beautiful equity curve can be an artefact of overfitting, survivorship, costs ignored or one lucky regime. Before you fund, scale or trust a strategy, it should survive an independent, documented attempt to break it.
One principle: before trusting a system, we try to break it — in a controlled, documented way. We work across context, data, performance, calibration, robustness, bias, drift, fragility, overfitting and operational risk, then summarize a Proof Score and recommendations.

No. We do not provide financial advice, investment recommendations, trading signals or market predictions.
No. We assess robustness and fragility; we never tell you what to trade.
Per-trade P&L or an equity curve, ideally with parameters and the testing period; more data improves confidence.
Strategy Lite is a free, simplified robustness check; the full validation adds out-of-sample, walk-forward, Monte Carlo and sensitivity, defensible before a committee.
