Exchange Designated Complex Instruments (C1 only)

In addition to customer creation of complex instruments, the Exchange may designate certain complex instruments to exist as needed by dependent Cboe products and services. The Exchange will ensure that such designated instruments exist, either from having been created by a customer request or by Exchange directed creation. In either case, standard Complex Instrument Definition (CID) messages for designated complex instruments will appear on the Complex PITCH and TOP feeds similar to all other complex instruments.

One or more supplementary Exchange Designated Complex Instrument Definition (EDCID) messages will be sent on the Complex PITCH and TOP feeds for each designated instrument that associates a complex instrument with a dependent service. The same Exchange Designated Complex Instrument symbol reference data will be made available on the Cboe US Options Reference Data webpage for each dependent service.
