TradeHouse Fidelity Lab (overfit validator) ยท Buyer resources
Fidelity Lab vs doing your own walk-forward
A 26-method integrity harness that checks whether a backtest is overfit, with a $99 one-time audit or $399 five-audit pack and monthly Starter $49 / Pro $149 tiers. It is aimed at traders who want an independent check before risking capital.
Walk-forward testing evaluates successive unseen periods. Fidelity Lab adds an integrity-review workflow; neither a subscription nor one walk-forward run establishes that a strategy will generalize. Compare reproducibility, trial accounting and leakage checks.
What to verify before buying
- Untouched out-of-sample periods
- Total number of tried strategies
- Leakage controls and execution costs
