What is Donchian channel?

What does Donchian channel mean in practice?

The upper line is the highest high of the last N candles and the lower line the lowest low. A close above the upper line is a new N-period high, which a breakout strategy reads as a possible start of a trend. The middle is sometimes drawn as the average of the two.

It is a classic trend-following tool because it is simple and fully mechanical: there are no subjective choices beyond N. The weakness is the same as any breakout rule. In ranging markets it produces repeated false breakouts, so it needs testing on the market and timeframe you intend to use.

A worked example

Illustrative only: with N = 20, the highest high over the last 20 candles is 110. A candle closing at 110.5 breaks above the channel and triggers the rule.

How to read or test it

Test a range of N values rather than a single one and look at the shape of the results: a broad plateau is reassuring, while one good value surrounded by poor ones is a sign of fitting. Test it on the specific market and timeframe you intend to trade, and compare trending and ranging periods separately. Remember that breakout rules usually have a low win rate and rely on a few large winners.
