Color bars of chart based on ATRTrailingStop

This solution is nothing more than just a simple paintbar study. Which is why I have updated the title of your question to make it easier for folks to locate this using search.

For this solution, I use the AssignPriceColor() function to set the color of each bar on the chart based on its relative position to the ATRTrailingStop values. By using the AssignPriceColor() function to solve this, the solution works for every single "Chart Type" available on Thinkorswim. (Area chart type does work, but it doesn't look very appealing).

I have included a screenshot below which shows how this solution shows up on four different chart types available on Thinkorswim. Your line chart is shown in the bottom left.

The colors can be adjusted exactly the same way as the original ATRTrailingStop chart study.

input trailType = {default modified, unmodified};
input ATRPeriod = 5;
input ATRFactor = 3.5;
input firstTrade = {default long, short};
input averageType = AverageType.WILDERS;
plot trailStop = ATRTrailingStop(trailType, ATRPeriod, ATRFactor, firstTrade, averageType).TrailingStop;
trailStop.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
trailStop.DefineColor("Buy", Color.GREEN);
trailStop.DefineColor("Sell", Color.RED);
trailStop.AssignValueColor(if close < trailStop then trailStop.Color("Sell") else trailStop.Color("Buy"));
AssignPriceColor(if close < trailStop then trailStop.Color("Sell") else trailStop.Color("Buy"));
