RemoveDrawObject not working for TrendChannel items

[foxthorn]

I can't seem to get RemoveDrawObject to remove user drawn TrendChannel lines.
It will however remove those TrendChannel lines created by the indicator but not those drawn by the user.

I've attached a sample indicator that demonstrates this.
Add a few TrendChannel lines then load the indicator and wait for a market tick to happen.
Notice in the Output window that it finds them but they are not removed.

Thanks for your help.

Hello foxthorn,

Thank you for your note.

Unfortunately there is not a way to remove manually drawn lines.

Please let me know if I can be of further assistance.
