What’s working, what needs tuning, and which 2 tweaks would flip it. Usually 60-90 seconds.
Most backtests lie about real-world fees. We publish where ours does.
Real Binance fees. Real per-coin spreads. Three years of walk-forward data so nothing looks good by accident. Every night we measure where our backtest predictions disagree with our forward-test reality, and publish the gap at /calibration. Most strategies don't survive. The ones that do, and the 2-tweak fixes that save the borderline ones, are worth finding.
We tested 20 popular strategies with real fees.
Here's the gap between what YouTube claims and what your account would actually look like. Same strategies. $1,000. Two years.
80% of retail algo traders lose money to overfit backtests. Six gates we use to catch it.
Most retail backtesters skip the validation stack that actually catches overfit. Pine Script has no built-in walk-forward. Freqtrade leaves it DIY. The marketplace bots run on selection bias. We use the same six gates a quant fund would use, applied to every strategy you submit:
Every gate is in the public audit trail at /architecture and the nightly calibration log at /calibration publishes where our backtest predictions disagree with our forward-test reality. Most platforms don’t measure that gap. None publish it.
Built to catch the backtests that look bulletproof and aren't. Independent, no VCs, honest about the losers.
