The right way to share data between drawing tool and indicator.

[ntdev]

I want to mark up the chart with my custom drawing tool and then have my custom indicator do things with the stuff that I've drawn on the chart.

Solution #1 - use files

I can have the drawing tools write data to the disk and have the indicator load the data.

But then I'll have to deal with knowing when updates have happened.

Solution #2 - static variables?

Haven't tried this but it seems that I can have my custom drawing tool have a static variable with a list of all the things it's drawn then access this from the indicator by including the namespace from the drawing tool.

For this I would have to make sure that both the drawing tool and the chart are installed.

Solution # 3 - maybe there's a way to get a list of all the objects drawn in the chart?

Is there a right way to do this?

Hello ntdev,

Welecome to the NInjaTrader support forum.

The #3 would be the correct way, We have an example of working with the drawing objects in the following page: https://ninjatrader.com/support/help...ub=drawobjects

Depending on what data is needed you would either gather the default property values from the object or cast to the correct type and get its custom properties.

I look forward to being of further assistance.

THANK YOU!

That's exactly what I needed.
