Backtests you can actually trust
Most backtesting tools let you overfit without knowing it. Our credibility pipeline applies six layers of validation — from data isolation to statistical significance — so you know if you found real alpha or just noise.
3-Way Data Split
Train / Validate / HoldbackTrain (50%), Validation (25%), and a 1-year minimum Holdback period the strategy never sees during optimization. Holdback returns are the true out-of-sample test — no peeking allowed.
Walk-Forward Validation
Auto-filter, 5 windows5-window rolling train/test within the training period automatically filters strategies before they reach validation. Strategies that fail walk-forward are eliminated — no manual step required.
Deflated Sharpe Ratio
Bailey & López de Prado (2014)Corrects for selection bias when testing hundreds of parameter combinations. Know whether your best Sharpe is genuine or inflated by data-snooping.
Monte Carlo Significance
Permutation test, 95% confidenceShuffles daily portfolio returns to destroy timing signal, then tests if your strategy has real alpha. Block bootstrap preserves serial correlation. Only p < 0.05 passes.
Realistic Commission Models
12 broker presets12 broker commission presets including IBKR Pro (Tiered & Fixed), Robinhood, Schwab, Fidelity, E*TRADE, and more. Per-share rates, minimums, maximums, and regulatory fees — not flat estimates.
Parameter Robustness
Broad plateau detectionVaries each parameter ±20% and checks if performance degrades smoothly or collapses. Strategies that only work at one magic setting are flagged as curve-fitted.
Every optimizer result shows a credibility rating: High, Medium, or Low — combining all six layers into a single actionable signal. Holdback period returns give you the closest thing to live trading performance before risking real capital.
