Chart-Shading-for-PrePost-Market

I'm doing this all time to differentiate the Pre/Post market with the regular market.



It's pretty simple (code below) but it sure would make life easier if this were automatic, or even selectable as a Chart Preference. "Like" if you agree!

CODE:
         if (!bars.Market.IsOpenMarketTime(bars.DateTimes[idx]))
            SetBackgroundColorAllPanes(bars, idx, WLColor.FromArgb(75, WLColor.Gray));
