About Bollinger Bands

Bollinger Bands are a 20-period moving average plus and minus 2 standard deviations. Price touching the lower band signals oversold (mean-reversion entry); breaking the upper band signals momentum (breakout entry).

Strategies that passed all six gates

These cleared walk-forward validation, deflated Sharpe correction, real Binance fees, cross-coin transfer, holdout window, and regime-stratified consistency.

Honest losses (autopsies)

Bollinger Bands variants that did not survive the gates. We publish these because most public backtest libraries only show wins. We think the failures matter more for calibrating your expectations.
