A variation of Deviation Stops (DevStops) indicator.
Some are wrongly calling this version a Kase DevStops (which it is not – Kase DevStops indicator is calculated in a quite different way), but this version has its good points too and can be used in regular support/resistance mode.
Additionally each DevStop value is colored according to the slope (trend) of the line – when all are aligned in the same direction, it can be treated as a confirmed trend change.
