I am able to stream stock data.  
I can access historical option data  
I have a paid subscription.  
I can not stream option data.  
I am using the C# SDK nuget package.

What can be preventing me from streaming option data? Any ideas?

I think you’ll need to add some more context if you want anyone to be able to help you. What errors are you getting?
