Drawing Tool. Accessing Volumetric Bars Data from within a Drawing tool

[Don22Trader1]

Hello,

I am working on a drawing tool that works similar to the order flow volume profile drawing tool. It is a draw and drop tool that calculates the delta percentage of the user defined range. Everything thus far works fine and I can make the tool render text onto the chart where I want. The issue is coming from accessing the volumetric data, specifically the delta for each bar. It is the missing puzzle piece to finish the project. I saw other conversations talking about using BarsRequest to access this info. I am asking if another work around has been discovered?
Thanks

Hello Don22Trader1,

Thank you for your post.

GetAttachedToChartBars() allows you to get the bars object that the drawing tool is attached to:

To access the bar delta, you will need to do some type casting to access the properties and methods of the bar type (Volumetric). Please see this Help Guide page for Order Flow Volumetric Bars that has code demonstrating:

Please let me know if you have any other questions.
