Drawing tool sample for newbies

[Powerbucker]

Hi,

I need to develop a custom drawing tool, but I don't know the structure of a drawing tool. Could you show me a simple example to guide me through the process?

I basically need to know how to click on the graph and at the point where it was clicked, draw a line for example.

From a simple code, I can go looking and learning how to develop my drawing tool.

Thanks

Hello Powerbucker,

You may find this example of the custom line drawing object isolated to a new script helpful.

Also, below is a link to the help guide.

The OnMouseDown override method is where you can get the mouse point from the dataPoint.GetPoint().

Great !!

Is possible change the color of ChartAnchors of my drawing tool? I'd like to distinguish the initial anchor from the final one

Thanks

Hello Powerbucker,

Unfortunately, the anchor selection points are rendered by NinjaTrader in the core code which you are not able to modify.

I'm not aware of a way to change the color of these.
