CME Globex Notices: April 25, 2011

New Mandatory iLink Tags
The new mandatory FIX tags which will enhance customer support and assist in market oversight are currently accepted in production on inbound iLink messages. Customers may begin populating these tags now; the final deadline is June 5, 2011. The five new tags will be used to identify:

• Front-end system
  • Should reflect the gateway application logging into the iLink session id
• Automated trading indicator flag
  • Does not have to dynamically change on a per-order basis from manual to automated
• Country of origin
  • Should reflect trader’s primary location; does not have to dynamically change based on trader's current location
  • For automated systems, the tag should denote the location of the system operator, not the trading system

To ensure customer readiness CME Group recommends the following action items must be completed prior to the June 5, deadline:

• System Providers
  All customer order routing systems must complete the mandatory certification via AutoCert+ and support the population of the new tags; CME recommends this be completed by early April 2011 to allow customers sufficient time to download the software and populate the tags prior to June 5th.
• Trading customers
  • Ensure customer country/state information is gathered in preparation of populating the tags. This should be completed prior to an updated trading system being deployed.
  • Implement any proprietary or third-party software that enables populating the new mandatory tags.
  • Populate the new tags prior to June 5.

These tags are available in New Release for customer testing. There are no impacts to FIX/FAST market data with this launch. Please contact your   Global Account Manager with any questions.

Please see the updated   Client Impact Document for a more detailed description of technical and data requirements.

 S&P Indexes via Streamlined FIX/FAST
In late Q2 2011, CME Group is launching streamlined FIX/FAST, a new version of the FIX/FAST market data format, optimized for non-actionable price data. The initial launch of streamlined FIX/FAST will support S&P Indices market data. Streamlined FIX/FAST has a   dedicated message specification distinct from the CME Globex FIX/FAST format and a new template.

Please note: CME Group recommends customer systems pull the templates from the CME Group ftp site every week, prior to Sunday start.

To ensure S&P customers currently receiving ITC 2.1 market data have sufficient time to develop, certify (if applicable), and deploy the streamlined FIX/FAST solution, ITC 2.1 market data format will continue to be disseminated for approximately 5 months following the streamlined FIX/FAST launch.

Effective Monday, May 9, 2011, new functionality will only be implemented on streamlined FIX/FAST. Index launches will be supported on both ITC 2.1 and the new streamlined FIX/FAST.

Streamlined FIX/FAST will be available in New Release for customer testing on Monday, May 9, 2011.

Detailed information for S&P Indices via streamlined FIX/FAST is available online in the   Client Impact Assessment.

 Revised iLink Session ID Auto-Deletion Process
Effective Monday, May 9, CME Group will implement a revised quarterly iLink session ID auto-delete process. CME Group will replace the previous login requirement to avoid auto-deletion with a minimum message threshold requirement. This threshold will initially be set at 100 messages over a 6-month period; any iLink session ID with fewer than 100 messages will be flagged for deletion. For the purposes of this policy, a message is defined as an order, modify, cancel or mass quote.

Idle iLink session IDs needlessly consume resources and make load balancing and resource allocation planning more difficult. CME Group is committed to managing session IDs to ensure the best performance on CME Globex for our customers. The iLink session ID auto-delete process helps ensure these resources are managed proactively and consistently across the marketplace.

Details on the process are available   online. An e-mail notification will be distributed to Class A clearing firms on Monday, May 9. Class A clearing firms will have six weeks to review their idle session IDs. All idle session IDs will be deleted at end of day June 24.
