Market Maker Trade Notifications (C1 Only)

Floor Trade Notifications (MMTNs) will be sent to Market Makers if they are identified as the contra party of a floor trade. MMTN messages will be sent over a designated FIXDrop or BOE order entry port. See Port Attributes for information on available port attributes related to MMTNs.

Market Makers that receive a Floor Trade Notification should use the Floor Trade Confirmation message to respond to the MMTN if they agree with the terms of the trade. Alternatively, a Market Maker can use the Add Floor Trade message to enter their own version of the trade.
