What is Donchian Zig-Zag?
Donchian Zig-Zag draws stepped red and green boundaries together with a blue line connecting major swing highs and lows. The stepped levels help frame nearby resistance and support, while the ZigZag simplifies the broader sequence of market swings.
Seeing both elements together makes it easier to separate minor candle noise from the main path between important turning points.
How to use Donchian Zig-Zag
Use the blue line to identify rising or falling swing structure. Then watch the upper red/orange steps and lower green steps for potential reactions as price approaches them.
Do not trade every ZigZag turn in isolation: recent points may update as new extremes form. Look for candle confirmation near a stepped level and use the previous swing as a logical reference for invalidation or profit planning.
Where it helps
The blue line makes higher highs, lower lows, and reversals easier to follow.
Stepped upper and lower levels provide extra reaction context.
The combined display helps traders wait for price to return to an area of interest.
