BTC Donchian Breakout
A trend-following breakout strategy that buys Bitcoin on new 20-day highs and exits on 10-day lows — a crypto take on the classic turtle channel system.
Last updated June 18, 2026
The idea
The BTC Donchian Breakout strategy adapts the famous Turtle Traders system to crypto. It assumes that when Bitcoin makes a new multi-week high, momentum is likely to carry it further — so it buys strength and lets trends run, cutting losses quickly when the move fails.
How it works
- Entry — go long when price closes above the highest high of the last 20 periods (the upper Donchian channel).
- Exit — close the position when price closes below the lowest low of the last 10 periods (a faster trailing channel).
- Risk — size the position so a stop at 2× ATR(14) below entry risks a fixed fraction of the account.
Why an asymmetric channel
Using a slower channel to enter (20) and a faster one to exit (10) lets trends develop before committing, while exiting quickly once momentum rolls over. This asymmetry is the heart of classic trend-following.
Parameters to tune
| Parameter | Default | Notes |
|---|---|---|
| Entry channel | 20 | Longer = fewer, higher-conviction entries |
| Exit channel | 10 | Shorter = tighter trailing exits |
| ATR stop | 2× | Controls per-trade risk |
