Donchian Breakout

Overview

The Donchian Breakout strategy is the direct descendant of Richard Dennis’s famous Turtle Trading system from the 1980s. It enters when price breaks above or below the 20-period channel — a signal that a new trend may be establishing.

SHORT direction has shown consistent profitability across both bull and bear market regimes, making it one of the more regime-stable strategies in the system.

How It Works

1. Channel calculation — highest high and lowest low over the past 20 bars (look-ahead safe: uses bars up to but not including the signal bar)
2. LONG signal — current close breaks above the 20-bar high (upward momentum)
3. SHORT signal — current close breaks below the 20-bar low (downward momentum)
4. Entry — at the open of the next bar after the break
5. Exit — TP 10% / SL 8%

Why It Works (Thesis)

The 20-period channel captures significant price movements that break out of consolidation zones. When price violates a multi-week high or low, it often signals the beginning of a directional move rather than random noise. The SHORT side outperforms because crypto assets frequently exhibit sharp, fast sell-offs — channel breaks to the downside tend to have stronger follow-through than upside breaks in a market prone to liquidation cascades.

Regime stability (profitable in both bull and bear periods) reflects the strategy’s directional neutrality: it profits from volatility and trend, not from a specific market direction.

Results

Market regime	Profit factor (SHORT)
Bull market	1.27
Bear market	1.06

Profitable in both regimes — a key indicator of robustness.

Caveats

• Lower profit factor in bear markets (1.06) — thin edge that could disappear with transaction costs in high-frequency trading.
• LONG direction not separately validated; use SHORT unless you’ve tested LONG on your specific coins.
• Classic trend-following: suffers during choppy, range-bound markets.
• Not live-tracked on OKX. Backtest only.
