A sample to develop a drawing tool

Hello,

I would like to develop a custom drawing tool (similar to MC fibonacci retracement price lines).
Just to not invent again the wheel can someone send me a c# example so I
do not start from scratch?

Ay help is highly appreciated!!

Thanks

Hello gbulle,

Drawings are being added by the following prebuilt studies: TrendLines_Automatic and ZigZag. Please also see this example.
