exception while binding dynamic operation

[iantriestrading]

I'm trying to debug this error in the assembly version of my strategy:
Error on calling 'OnStateChange' method: An unexpected exception occurred while binding a dynamic operation

Any specific gotchas that can cause this? No errors when using the source code version of my strategy but when I try to activate the imported assembly version, I get that error. I tried adding debug prints in various places and nothing else logs except for that. Nothing inside OnStateChange is run at all.

Hello iantriestrading,

As this relates to your other post I will continue to assist in the other post for this message. There is not a specific reason that would be presented so we still need to figure out which part of your code is being called when you get the error. Using prints or the comment out method is going to be the best approach here.

Hey Jesse,

Can you delete this new thread then? I'll keep it in there, sorry
