Donchian Flux Cloud is a trend and volatility visualizer built from two Donchian channels (fast & slow) plus an ATR-based outer envelope.

The inner cloud tracks the fast Donchian range and flips color with the prevailing trend, while the outer band expands and contracts with ATR to show when price is breaking out into higher-volatility territory. It’s designed to highlight squeezes, breakouts, and regime shifts at a glance without cluttering the chart.
