Is your edge real — or a mirage?
Paste your backtest. We run the same honesty checks we use to kill our own signals — survivorship, overfitting (deflated Sharpe), single-trade dependence, regime robustness, and realistic cost — and tell you, plainly, whether the edge holds up. No signup. No AI. Just the math, and the math is reproducible.
This analyzes the hypothetical, past record you supply. It is an impersonal analytical tool, not investment advice, and it never predicts future returns.

“Variants you tested” = how many parameter sets, tickers, or re-runs you tried before settling on this one — it drives the overfitting haircut. Honest traders undercount; leave blank and we assume a conservative 10.
