Donchian Volatility Indicator - Adaptive Channel Width

The Donchian Volatility Indicator - Adaptive Channel Width tool provides a dynamic measure of market volatility by calculating the distance between adaptive upper and lower Donchian boundaries. It serves as a visual aid for identifying periods of market expansion and contraction, helping traders determine the suitability of breakout or mean-reversion strategies.

Usage

The indicator outputs a primary "Channel Width" line and a "Signal Line" (SMA of the width). Traders can interpret the relationship between these two lines to gauge market environment:

• Volatility Expansion (Green): When the Channel Width is above the Signal Line, it indicates that current volatility is higher than its recent average. This environment is typically favorable for trend-following and breakout strategies.
• Volatility Contraction (Red): When the Channel Width falls below the Signal Line, it suggests the market is entering a period of lower volatility or consolidation. This may favor range-bound or mean-reversion approaches.

Details

The indicator enhances the traditional Donchian Channel concept by incorporating an "Adaptive" element. Instead of simply using the highest high and lowest low, the script adds an ATR-based buffer (ATR Multiplier) to the calculation. This creates a wider, more responsive boundary that accounts for recent price ranges.

The formula for the width is: Channel Width = (Highest High + ATR * Multiplier) - (Lowest Low - ATR * Multiplier)

By comparing this width to its simple moving average (Signal Line), the tool filters out "noise" and highlights significant shifts in price activity.

Settings

• Lookback Period for Donchian Channel: Sets the number of bars used to find the highest highs and lowest lows.
• ATR Period: The timeframe used to calculate the Average True Range for the adaptive buffer.
• ATR Multiplier: Determines the sensitivity of the adaptive boundaries; higher values create wider channels.
• Lookback Period for Extremes: Defines the historical window for analyzing volatility extremes.
• Length of Signal Line: The period used for the Simple Moving Average that acts as the baseline for volatility comparisons.

FAQ

How do I use the alerts for this indicator?

The script includes built-in alerts for "Volatility Expansion" (Width crossing above Signal) and "Volatility Contraction" (Width crossing below Signal), which can be configured via the TradingView Alert menu.

Is this a leading or lagging indicator?

As it is based on historical Donchian and ATR calculations, it is a lagging indicator. It confirms existing shifts in volatility rather than predicting them before price action occurs.
