Hi
I understand that those future contracts are non deliverables with IB, so they would be closed by tws before expiration.
But what about the options on those futures ? I had no problem with GC options but reading messages on IB’s platform regarding ZB short puts expiring today it seems one needs to close them before option expiration, yet the underlying for those same ZB options is ZB march, which is not expiring yet.
Anybody here could clarify ?
Thanks in advance
