I get a cannot save xml error when I close the indicator.
I have used your example to add the property :
[CustomBrush]
public Brush MyBrush
{
get { return new SolidColorBrush(Color.FromRgb(25, 175, 185)); }
set { }
}
private Brush chartBackgroundColor = Brushes.Green;
From the indicator window I set MyBrush to chartBackgroundColor.
When I close the indicator I get the error message.
