Donchian Channel

Description

The Donchian channel can also be called the “4-week-rule”; this is how it works: when the current price reaches a peak above the high of the past 4 weeks, a new long position is opened. If a short position is open simultaneously, it is closed. This works vice versa with shorts. The Donchian channel trading system is a purely trend-following system based on the concept “buy when it is strong, sell when it is weak”. The famous “Turtles” also employed this breakout system. This indicator displays the highs and lows of the last n days as lines above and below the price development. 20 days represent 4 weeks.
