Donchian Breakout

Buy the highest high of the last N bars — the original turtle-trader strategy.

Donchian breakouts buy when price closes above the N-bar high. It captures regime changes — the moment a market wakes up from a range. Fails in chop (every false breakout is a small loss) but the long tail of trending wins more than compensates. Most profitable on volatile assets like XAUUSD and crypto.
