The Smart Donchian Cloud is a volatility channel indicator designed to visualize institutional supply and demand zones as dynamic support and resistance areas. It analyzes the relationship between candle wicks and bodies to plot three distinct "Pressure Clouds": the Resistance Cloud (cyan/blue) marking the selling zone, the Equilibrium Cloud (gray/silver) representing market balance, and the Support Cloud (pink/magenta) indicating the buying zone. This multi-layer cloud system helps identify high-probability reversal zones and market structure more effectively than traditional Donchian Channels.

Key features include an ATR-based volatility filter to reduce noise, and smart candle coloring that highlights breakout momentum—lime candles signal bullish breakouts above resistance, while red candles indicate bearish breakouts below support. The thickness of the clouds reflects volatility, with thicker clouds showing higher rejection or indecision.

Traders can use the indicator for mean reversion by spotting price entering but not closing above resistance, trend breakouts confirmed by lime candles, and support bounces where price touches the support cloud during pullbacks. The indicator’s parameters, such as lookback period and ATR multiplier, are customizable, along with cloud colors to fit user preferences.
