Thanks for considering it. The QT way works for me
1. Maybe in Settings, Charts/General, somewhere below the "Load Template Resizes Charts"? I personally just need to turn it "off" once, and if for some reason I'd want to change/test other indicators, I'd know where to find it.
2. Otherwise, in the chart itself, under "View" put a "Hide Legend", or better yet (best?),
3. Chart Indicator Selection, Selected Indicators, under "Parameters For RSI" (or whatever), add "Hide Legend".
Again, thanks.
