Donchian channels in gold trading
Donchian channels plot the highest high and lowest low of the last N periods; a close above the upper line signals a gold breakout to new N-period highs.
Also called Donchian channel, Price channel, 20-day breakout, Turtle channel
Donchian channels show the highest high and lowest low over a chosen number of periods, often 20, with an optional middle line halfway between. Developed by Richard Donchian, they are the basis of the classic channel-breakout trend systems, including the 20-day and 55-day breakouts of the Turtle traders.
How it applies to gold trading
A Donchian breakout system buys when gold makes a new N-period high and sells short on a new N-period low, usually exiting on a shorter opposite channel, such as a 10-day low. On gold, such systems capture the big trending months but suffer many small losses in ranges. Win rates are typically low and the profits come from a few large trends.
Intraday traders also use short Donchian channels to mark the session range, for example the high and low of the Asian session.
Worked example
Example (hypothetical numbers): the 20-day high is 4,060 and the 20-day low 3,920. Gold closes at 4,065, a 20-day breakout. A trader buys 0.05 lots with a stop at the 10-day low of 3,985, $80 away, risking $400. The trade is held until gold closes below its 10-day low.
A common mistake
Expecting a high win rate. Breakout systems lose often; their edge depends on letting the occasional big trend run.

Frequently asked questions
What Donchian channel period works for gold?
The classic choices are 20 and 55 days for entries and 10 or 20 days for exits. Shorter periods give more signals and more false breakouts.
Is the Donchian channel the same as the Turtle strategy?
The Turtle rules used Donchian breakouts as entries and exits, along with ATR-based sizing and specific risk rules.
Do Donchian breakouts work on intraday gold charts?
They can mark session ranges, but intraday breakouts face more noise and cost, so test them carefully.
