The idea in plain words

If the price makes a new 20-candle high, something has changed. Donchian Channels simply draw the recent extremes, so new highs and lows stand out.

How it is calculated

Upper = highest high of N candles, lower = lowest low, middle = halfway.

Upper = highest high (N)
Lower = lowest low (N)
Middle = (Upper + Lower) ÷ 2   (default N = 20)

How to use it

  • Breakout: buy a new N-candle high, sell a new N-candle low.
  • Use the opposite band (or a shorter channel) as a trailing stop.

Drawing conclusions

  • A flat upper band means no new highs: the market is not trending up.

Example

Crude oil breaks above its 20-day high of 82.40; the trend-following rule buys and later exits on a 10-day low.

Prices in examples are illustrative.

Watch out for

  • Breakout systems lose often in ranges and make money in the few big trends.

A little history

Richard Donchian pioneered breakout trend following from the 1950s; the famous "Turtle Traders" of the 1980s used Donchian breakouts.
