Floor Trade Notification Message Fields (C1 Only)

TPHs with Market Makers on the Cboe trading floor may optionally receive Floor Trade Notification messages. TPHs must request the Enable Floor Trade Notifications port attribute be enabled for one or more floor acronyms in order to receive these messages.

TPHs are encouraged to use Floor Trade Confirmation messages to respond to Floor Trade Notification messages if they agree with the terms of the trade. Alternatively, an Add Floor Trade message may be used to enter their version of the floor trade. If the floor trade notification is not known to the Market Maker (for example, if the TPH is misidentified as a contra party to the floor trade), the message can be disregarded; a response is not required.

TPHs configured to be automatically endorsed to floor trades will not receive a Floor Trade Notification message; only an Order Execution message.
