What Are Donchian Channels?

Donchian Channels are a trend-following technical indicator used to identify breakouts, support and resistance levels, and market volatility.

The indicator consists of three lines:

• Upper Channel – Highest high over a selected period
• Middle Line – Average of the upper and lower channels
• Lower Channel – Lowest low over the same period

Developed by Richard Donchian, often called the “father of trend following,” this indicator is widely used by traders to capture strong price movements. Donchian Channels plot the highest high and lowest low over a defined lookback period.

History of Donchian Channels

Richard Donchian introduced this indicator to help traders follow trends systematically. His methods later inspired famous trading systems such as the Turtle Trading strategy.

The core principle is simple: when price breaks above the highest high of recent periods, momentum may continue upward; when price breaks below the lowest low, downward momentum may continue.
