IF XAUUSD had two decimal places add XAUUSD = 0.1 to pip size rules (Spanner Icon top right)
Zooming out on your browser creates more space to work in. (Zoom settings in your browser eg. Chrome 3 dot menu top right)
2147483647 in a buffer means indicator is invisible
implicit conversion from number to string error Meta Editor - Value set to text instead of number - [If you have draw text boxes check their settings]
Problem optimizing in MT4 - Discovered it was the Donchian Channel indicator - Downloaded a different version and changed it in the EA. Optimizing now works.

@johann-0 Didn't try that one on zooming out so far. Thank you for sharing.
