Please Note: Requests for bid-ask relief on a class by class basis should be directed to BOX Exchange. Requests must include an explanation as to why bid-ask relief is needed. If a particular option class was granted bid-ask relief through an expiration period and the relief is greater than the below bid-ask differentials, the relief granted will continue through the expiration period.
