Donchian Channel Breakouts for Trend Following

Summary

This document describes a basic channel breakout strategy using the highest high and lowest low over configurable lookback periods. It places a long entry when price reaches the upper channel and uses the lower channel as an exit; the accompanying explanation also describes selling on a downside break. The example parameters set both channel lengths to 20 and allow a date range for historical testing.

The document offers no performance results, only a short list of general strengths and risks. It warns that false breakouts and pullbacks can cause losses, that channel lengths affect behavior, and that historical results may be biased or differ from live trading. The source logic has additional limitations: it lacks a short-entry rule and an explicit stop-loss or take-profit framework, and its end-date calculation appears to use the start-date inputs. These details make the example useful as a simple illustration, rather than evidence of a validated trading system.

Key ideas

• The strategy defines upper and lower channels from rolling price highs and lows.
• An upper-channel break triggers a long entry, while the lower channel is used to exit that position.
• Lookback lengths are adjustable and should be evaluated across market conditions.
• False breakouts, parameter sensitivity, and backtest bias can undermine results.
