    Lines not deleting properly

    Hello, I have an indicator that is doing analysis of user drawn lines. After the user deletes a line, the code can still "see" the line, even though it is deleted. Is there something that I can do to purge these semi-deleted lines?

    For example, if I run this, it will list lines that are not longer there!

    foreach(IDrawObject draw in DrawObjects)
    {
    if (draw.DrawType == DrawType.Line) {
    Print("Line: " + draw.Tag);
    }
    }

    Running RemoveDrawObjects() doesn't fix this, but I suppose that's to be expected, since the code cannot delete user created lines, correct?

    Thanks!

    Hi Daniel, that's unfortunately expected for the reason you stated and also there would not be an event for a drawing object change that would be needed here - this is on development's feature list for future consideration.

      Thank you for the response. I'm a little confused on why it's expected. If I'm initiating a built in functionality of NinjaTrader it should be using it's built-in events to handle the creation and deletion of that object, correct? I'm not overriding those.

      Yes, definitely having event handlers for drawing objects changing, deleting, etc would be greatly appreciated! RemoveComplete and InsertComplete are both called very often, so I have to use work arounds to make them useful.
