Configuring Order Management
Note: Terminology used in the following data flow matches terminology used in the Gateway
System - Logical Architecture diagram. Also, native orders are those orders normally
accepted by the exchange's API.
The following is a description of the Order Feed connection from the Order Server
on the CME Gateway to the exchange.
• Upon startup, the Order Server reads any working orders contained in the
*_SessionIdMemberId_Mode_orders.tbl files into memory.
• X_TRADER® submits an order to the Order Server.
• After receipt, the Order Server passes it to the appropriate Order Router.
For details on how the Order Server determines the Order Router to which
it passes the order, refer to the section called Order Router
Determination 7.14.x on page 95.
• The Order Router assigns a TON to the order and then updates the Order
Book with the new order information.
• The Order Router records the order in its
*_SessionIdMemberId_Mode_orders.tbl files.
• The Order Router sends an ACCEPT/Add message to the trader’s Audit Trail
(in X_TRADER®).
• The Order Router sends the order to the CME Group host.
• Upon receipt, the CME Group host sends an order confirmation (containing
the TON) back to the Order Router. For further information on the TON,
refer to the section called Trade Order Number on page 110.
• The Order Router updates the Order Book with the TON Number to indicate
that a confirmation was received, and writes it to its
*_SessionIdMemberId_Mode_orders.tbl files.
• The Order Router sends the order confirmation (as an OK/ADD) to the
trader’s Audit Trail in X_TRADER®.

• X_TRADER® submits an order to the Order Server.
• After receipt, the Order Server passes it to the appropriate Order Router
(i.e., session connection).
• The Order Server assigns a TON (Trade Order Number) to the order and
then updates the Order Book with the new order information. For further
information on the TON, refer to the section called Trade Order
Number on page 110.
