Is there a way to test for the existence of a specific drawn object on the chart, given the tag name is known? If not, please make one?
Similar to RemoveDrawnObject("unique_tagname") only a test for existence that simply returns a boolean flag...

There are times I want to modify a previous object, but not draw one if it doesn't exist. The original object creation logic is far too complex to repeat and would unnecessarily slow down the code, when all I want to know is if there's a drawn object of that name on the chart already.

Thanks for your suggestion. We'll add it to the list of future considerations.

Note: You always could maintain a collection of tags managed by your code.

One alternate suggestion that might be easier to implement:
simply put the boolean return code on the RemoveDrawObject() method.
True if successful, false if not there. That might be simpler for your coders to implement.

Thanks!
