Lower Band Break Fade — Ethereum strategy backtest
Buys a close beneath the lower Bollinger band, exits at the middle band, with an ATR volatility stop
A curated strategy — a well-known mechanism with sensible risk management built in. Still not a recommendation — it's a mechanism you test yourself.
- • Buys when Close price is below Bollinger Band(20,2) lower.
- • Sells when Close price is above Bollinger Band(20,2) mid.
- • Uses a volatility (ATR×3 over 14 bars) stop.
- • Exits after 15 bars if still open.
