Donchian Channel Breakout Strategy
Overview
This strategy uses the Donchian Channel indicator to trade breakouts of the upper and lower bands, enabling trend following operations across stocks/futures/crypto/forex etc, belonging to medium-to-long-term trend breakout strategies.
Strategy Logic
-
Calculate the highest high and lowest low over a given period (e.g. 20 days) to get the upper and lower bands.
-
The midline is the average of the upper and lower bands. Breaking upper band signals uptrend, breaking lower band signals downtrend.
-
When price closes above upper band, determine uptrend has started, go long to enter.
-
When price breaks below midline, take profit to exit.
-
Can reference backtest timeframe to generate actual trading signals.
-
Optionally, breaking lower band can also act as short signal.
