    Hello trader3419,

    Thank you for your post.

    The exception indicates that the indexing in accessing a collection was outside the valid range.

          Patrick. I am realizing that this issue, along with another one of mine where the Templates for drawing tools won't work have stemmed from the same point. I had created a indicator on my end, which works great. I exported it as a compiled assembly, but did not protect it. I gave it to my friend to use it, and both those bugs appeared for him. I then sent him the original code and neither issue happened anymore.

          Can this be looked into? Both the Invocation Error and Drawing Templates not working when code is exported as a compiled assembly.

            Hello trader3419,

            Yes, we can look into both matters. I will follow up with you via email so we can test the files.
