Cabinet and Sub-Cabinet Orders (C1 Only)

Cabinet orders are identified via PriceType=0 and must have a valid TimeInForce=Day or GTC. Cabinet orders can support a position status of Open or Close identified via the OpenClose field. Cabinet orders will only trade with other cabinet orders on the floor and therefore require direct or default floor routing instructions as described in Floor Routing (C1 Only).

Orders in non-penny classes must have a limit price less than or equal to $0.01 and orders in penny classes must have a limit price less than $0.01. Limit prices may be up to 4 decimal places.

Orders in penny or non-penny classes priced greater than $0.01 and orders in penny classes priced equal to $0.01 will be rejected. Orders with a limit price that locks or crosses a resting non-cabinet order will be rejected.

Cabinet orders or executions will not be disseminated on OPRA but will be available on the Cboe U.S. Options Multicast TOP and PITCH feeds.
