Donchian Channels for Volatility Context and Breakout Signals

Summary

A Donchian Channel is built from the highest high and lowest low over a chosen lookback period, with the range between them marking the channel. The described indicator also plots the midpoint between those bounds and a moving average of that midpoint. Channel width gives a visual sense of recent price variation: a narrow range accompanies relatively stable prices, while a wider range reflects larger fluctuations.

The main trading interpretation is a breakout rule: a trade above the lookback-period high signals a possible long entry, and a trade below the lookback-period low signals a possible short entry. The note explains the indicator’s four chart lines and says the lookback and midpoint moving-average settings can be configured. It gives no tested results, exit rules, or risk controls, so the breakout signals are a basic method description rather than evidence of a profitable system.

Key ideas

• The upper and lower channel bounds are the highest high and lowest low over a selected lookback.
• The midpoint is the average of the upper and lower bounds, and it can have a moving average.
• Channel width offers a visual indication of recent price fluctuation.
• A move above the upper bound is described as a possible long signal.
• A move below the lower bound is described as a possible short signal.
• No backtest, exits, or risk-management method is provided.
