I'm facing a problem! I can get the Handles of two custom indicators using ChartIndicatorGet (Donchian [Main chart Window] and RSI[Separate window]). How can I apply the RSI handle to the Donchian handle and add the resulting handle to the separate window.

Thank you very much! Many people here on the forum say that icustom has problems, but with great calm and dedication I managed to use it without any problems. An important function, practical and very simple to use. Once again, Thanks!
