working on my first javascript indicator for Tradovate. So far everything seems to work great without any bugs. That said, I'd like to make two changes:

• Histogram to plot > 0 (green) only if period1Avg is greater than the HIGH of period2Avg.
• Histogram to plot < 0 (green) only if period1Avg is less than the LOW of period2Avg.

This would inherently mean that some sections of the histogram would not plot (i.e. value of 0).

Any assistance on how to edit the script to reflect these changes would be much appreciated!
