Plug in your strategy and get a HULK-grade honesty report — deflated-Sharpe, PBO overfit probability, plus skew, tail and warehoused-risk flags — on a cross-venue resolved settlement tape no competitor has.
Get your free Strategy Health Score → See plansQuantConnect-style tools show you a pretty equity curve. They don't tell you the curve is curve-fit. We run the same overfit, skew and warehoused-risk checks our own live-capital validator (HULK) must pass before a single dollar trades — and hand you the verdict.
Everyone can backtest on price candles. We score your strategy against a cross-venue, resolved, settlement-truth prediction-market tape — Kalshi, Polymarket, Limitless and more — normalized into one plane with real fees, latency slippage and adverse-selection skip deducted (near-live fidelity). Single-venue data exists; the resolved, calibration-grade, cross-venue tape does not — except here.
Paste a realised return series, get an honest 0–10 score + plain-English risk tags in seconds. No card, no data licence.
