Walk-forward · Deflated Sharpe · real L2 spread · live paper-traded

Prove your trading strategy actually works

Type your idea in plain English. We test it against 3 years of real Binance data with honest fees and per-coin L2 spread sampling. You get a verdict in under 2 minutes. No signup. No credit card.

Walk-forward validation

Your strategy is optimized on one window and tested on a later, unseen window. The number you get back is the out-of-sample number, not the in-sample one. How walk-forward works

Binance maker/taker fees, per-coin L2 spread sampled from live order books, no perfect-fill fantasies. Why fees and slippage kill backtests

Statistical honesty

Deflated Sharpe ratio accounts for how many candidates we tested, so a fluke can't pretend to be a winner. Why most crypto backtests lie
