In detailed chart view (i.e. tradingview style) I am changing the opacity of the gridlines to 50% to make them less intrusive. I click ok and the new style shows for the current instrument. But when I click on another instrument in the horizontal bar across the top, then back to the same instrument I was on originally, the gridlines are back to their default 100% opacity. I assume this is a bug, or am I just missing something?
