CME Group Recovery
Processes
6 Disaster Recovery
Depending upon the particular type of failure, the following items occur
(reconnection does not occur in any particular order):
• If the MDP server failed, the Price Server on the CME Gateway reconnects
to the CME Group exchange host. Prices go live again.
• If the iLink Server failed, the Order Routers on the CME Gateway reconnect
to the CME Group exchange host. Traders can now trade.
• Fills: Unless fills were dropped by CME Group, traders have access to their
fills for the entire trading day. Traders see their fills for the day redownloading.
• Orders: Due to the possibility of orders being dropped by CME Group
during an iLink server or CME Group exchange host crash, traders must call
the exchange and verify their working orders.
• Position: Because the CME Group exchange host may drop fills or orders
during a failure, upon reconnection, traders may have incorrectly
calculated positions. To determine correct positions, traders must call CME
Group and inquire upon all orders in their Order Book.
Additionally, in a crash situation it is possible that Cancel on Disconnect
functionality can cause stale orders. Traders should inquire on their orders
with the CME Group to verify the accuracy of all information.
Warning: If the Cancel on Disconnect functionality creates stale orders,
they will be deleted from the Order Book if inquired in X_TRADER® using
the Inq button in the Order book.
If you subscribe to CME Group’s Cancel on Disconnect functionality, recovery
occurs as described in the section called Cancel on Disconnect on page 118.
Cancel on Disconnect CME Gateways support the exchange’s Cancel on Disconnect functionality. To
enable this functionality, you must subscribe for the free service through the
Globex Control Center (GCC). The exchange enables this functionality based on
registered session ID and trader ID pairs.
The Cancel on Disconnect service monitors for involuntary disconnects. Once CME
Group detects a disconnect, the exchange cancels all day orders except for
GTDate and GTC orders.
In certain situations, some orders may not be cancelled by the exchange.
Following a disconnect, customers should contact the GCC to determine their
correct positions and inquire on all orders in their order book.
