    RemoveDrawObject(tag) gives this message when I try to loop through all text tags.

    Bar 14 is just an arbitrary staring point. Message occurs for any value.
    This thread deals with that exact issue. If you read it, you will get the code to do what you want. http://www.ninjatrader.com/support/f...ad.php?t=44194

    Hello roland_nt,
    Thanks for writing in and I am happy to assist you.

    You cannot delete any object the collections while in a foreach loop. Thus you cannot use the RemoveDrawObjest(tag) code within the foreach loop.

    This is a more of a c# query and please refer here for more details

    Please let me know if I can assist you any further.
