I prefer use large Length input for more stability at mean and standard deviation values.
Uses 5 colors, by default:
- Red = >= 4 stdev;
- Orange = 4 stdev > >= 2.5 stdev;
- Yellow = 2.5 stdev > >= 1 stdev;
- White = 1 stdev > >= -0.5 stdev;
- Aqua = -0.5 stdev > .
I coded another script, called "Colored Volumes Histogram". It uses the same idea, but color directly the histogram. https://br.tradingview.com/script/8XYEKJBs/
