I thought I put this request to the forums but may have emailed it as part of beta testing feedback.
It would be great to be able to see open interest, perhaps as of the prior days close if that is all that is available, for the snapshots and options responses for a given options symbol. Also, the volume of the day thus far if a current day or the full day or a prior day.
If this is out there and I’m missing something please correct me. Right now it seems you can only see quote sizes and last trade sizes in regard to volume, and no open interest info.
