CME Globex Notices: April 9, 2012

Changes to Source IPs for the Market Data Platform B Feed for Non-GLink Connections
Effective Sunday, June 17, 2012, CME Group will be changing multicast source IPs for the B feed only for non-  GLink connections. If a firewall or network device is configured with the source IP information, please correct your configuration to use the entire range of eligible addresses. Port, multicast addresses, and source IPs for each Market Data Platform channel are available in the config.xml file on the  FTP site as outlined in the Core Functionality of the  FIX/FAST SDK.

Market data will be broadcast on all CME Group FIX/FAST channels in the production environment for customer testing on Saturday, June 16. Market data will be broadcast from the new B feed source IPs.

• 8:30 - 9:00 a.m. CT: Connectivity testing
• 9:00 - 10:00 a.m. CT: FIX/FAST market data replay

As a reminder, CME Group requires that customers configure servers to connect to the Market Data Platform ports and multicast addresses for each desired channel. CME Group does not recommend restricting data flow via the source IPs, as these may change without notice.

If you have any questions or concerns, please contact your  Global Account Manager. If you experience any connectivity issues, please contact the CME Globex Control Center directly at 312.456.2391.

User-Defined Spreads: Covereds Execution Enhancement
Effective this Sunday, April 15 (trade date Monday, April 16), the execution for User-Defined Spreads (UDS):Covereds will be enhanced to better ensure delta neutrality.

Currently, in certain scenarios, the matching process may result in a Covered trade that is under- or over-allocated on the futures fills. Starting Sunday, March 25, 2012, the Covered matching algorithm will track executions of a resting order such that when the executed quantity of a customer's option order results in an accumulated delta futures allocation at or above 0.5, a futures contract is allocated to the next fill.

The enhancement is scheduled for a phased launch as follows:

• Sunday, April 15
  • CME Interest Rate Options
  • CBOT Interest Rate Options
  • COMEX Options
  • Green Exchange Options
  • NYMEX Crude Options
  • NYMEX Non-Crude Energy Options

We recommend all system providers supporting Covereds test this enhancement thoroughly in New Release. Details on UDS:Covereds functionality are available  online.

iLink Enhancements for MexDer via CME Globex
Effective this Sunday, April 15 (trade date Monday, April 16), a number of iLink enhancements will be launched for the Mercado Mexicano de Derivados (MexDer) North- to- South order routing solution.

These enhancements include:

• Implementation of new Cancel/Replace Request rules
• Acknowledgements for Account, Price or Quantity changes
• Mandatory In Flight Mitigation (IFM) for all MexDer products

Order Elimination Enhancement
Effective this Sunday, April 15 (trade date Monday, April 16), the process for eliminating Good till Date (GTD) orders with expirations set to a non-trading day will be enhanced.

GTD orders with expirations set for the immediately prior weekend or holiday will be eliminated at the Sunday start-up and Order Eliminations (tag 35-MsgType=8, tag 39-OrdStatus=C) will be sent out to customers.

Currently, Good till Date (GTD) orders with expirations set to the following holiday or weekend are cancelled after the close on Fridays and Order Cancels (35=8, 39=4) are sent out to customers.

For the Beginning of the Week Logon (35=A), if tag 34 is greater than 1, customers should issue a Resend Request (35=2) to recover the missing messages. Customers should rely on tag 34-MsgSeqNum to identify a message sequence number gap.

These changes are currently available in New Release for customer testing.

iLink Enhancement for Order Handling Flag
Effective Sunday, June 3, 2012 (trade date Monday, June 4), in response to Clearing Firm requests and in conjunction with a Futures Industry Association (FIA) initiative, iLink order routing will launch support for FIX tag 1031-CustOrderHandlingInst. This tag will allow trading and clearing firms to identify the source of any order.

The value submitted on a new order in tag 1031-CustOrderHandlingInst will be passed through to the CME Clearing House at trade, and populated on all FIXML trade confirmation and allocation messages. It will also be supported by the CME Clearing House Give-up Payment System (GPS).

When tag 1031-CustOrderHandlingInst is submitted on the New Order (tag 35-MsgType=D), it will be returned on all associated Execution Reports (tag 35=8).

Tag 1031 is currently available in New Release for customer testing.

Please contact the CME Clearing House at 312.207.2525 with any questions.

iLink Session ID Auto-Deletion Process
This Monday, March 5, CME Group executed its quarterly iLink session ID auto-delete process.

For the purposes of this policy, a message is defined as a new order (tag 35-MsgType=D), order cancel/replace request (tag 35=G), order cancel request (tag 35=F), and mass quote (tag 35=i).

An e-mail notification was distributed to Class A clearing firms on Monday, March 5. Class A clearing firms will have 4 weeks to review their idle session IDs. All idle session IDs will be deleted at the end of day this Friday, April 13. Details on the process are available  online.
