Hi, thanks for indi.

Does is possible to add settings that allow changing line thickness and shape (normal line, dots etc.) ?

Good job cmdpirx.

The same indicator but with added 3rd timeframe:

// ZigZag indicator, allowing the usage of multiple TimeFrames within one indicator
// In this sample three different TimeFrames, but it's expandable
// Based on kkostaki's ZigZag indicator, /algos/indicators/show/157
// Thanks kkostaki!
