Floor Representation Restatements (C1 Only)

Orders routed to the trading floor will be represented to the open outcry crowd before being traded in the crowd. The Cboe FIX protocol provides a mechanism for clients to request restatement of orders at the time of representation. See FIX Port Attributes and FIX Drop Port Attributes for information on available port attributes, including Floor Representation Restatements.

When enabled, Floor Representation Restatements are sent to connected clients for each order when the floor broker reports representation of the order to the crowd. Floor Representation Restatements sent to the FIX and BOE ports will also be sent to connected Order by Order Drop clients having the Floor Representation Restatements port attribute enabled.

Execution Report messages for floor representation will have ExecTransType (20) = 3 (Status), ExecType (150) = D (Restated) and ExecRestatementReason (378) = 7 (Represented in Crowd). The TransactTime (60) will be the recorded time of the representation.

To enable Floor Representation Restatements via port attribute setting, customers should complete a modification request using the Logical Port Request form within the Cboe Customer Web Portal.
