Conditional Coloring between Bollinger Bands

[pauly139]

I'm changing the color between Bollinger Bands dependent upon a determination of trend direction. To do that I'm using DrawRegion on each bar,

DrawRegion("Trend" + CurrentBar, 1, 0, KUpper , KLower, Color.Empty, trendColor, bandAreaColorOpacity)

This seems a pretty resource hungry method - does anyone have any alternate methods I could try which aren't such resource hogs?

Hi pauly139,

I am not aware of anything that would do that exact effect, but you might consider one of the other draw objects or just color the background with another color between your points of interest.

You could override the Plot method and use the standard Framework graphics objects.

I found an example here http://www.ninjatrader.com/support/f...9&d=1190425419

Been thinking about this for my own uses and thought:

I wonder if you plot 2 BBs and collapse #1 to 0 Std Devs when the trend is up and # 2 when the trend is down. Color both regions, #1 - Red, #2 - Green. Both regions will always be colored, however since one is always equal to the middle line, you won't or shouldn't see it.

I haven't tried it and it seems a terrible kludge, but it might be worth a try.
