I would like to display a Heiken Ashi chart in a separate window.
The problem I have is that when I use "#property indicator_separate_window", all the bars in the separate window appear at the same height and level. I would like it to be more like the main chart with the bars going up and down and of different heights.
Can anyone please help with this?
