Dual Donchian Channels for Asymmetric Breakout Signals

Article Strategy library · Author: ChaoZhang

Summary

This strategy uses separate lookback lengths for the upper and lower Donchian bands. It enters a long position when the close reaches or exceeds the prior upper band and closes that position when the close reaches or falls below the prior lower band. A midpoint, calculated as the average of the bands, is plotted for context but does not drive the trade rules. The published defaults use equal channel lengths, while the method allows them to differ.

The document explains that this trend-following approach is simple and adjustable, but offers no performance results to establish its effectiveness. It warns that false breakouts can trigger poor trades and that unsuitable lookbacks can make the rules too aggressive or too cautious. Suggested improvements include filtering with moving averages or volatility measures and adapting the channel lengths. The described implementation is long-only; it does not open short positions, and the offset parameter appears in the inputs without affecting the stated signal logic.

Key ideas

  • Separate lookback lengths define the upper and lower Donchian bands.
  • A close at or above the previous upper band opens a long position.
  • A close at or below the previous lower band closes the long position.
  • The midpoint is displayed but is not used as a signal.
  • False breakouts and poor parameter choices are key limitations.
