CME Globex Notices: April 4, 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.

The Q2 2011 CME Globex Messaging Policy benchmarks are now available   online.

The benchmarks are published quarterly and are based on the per-product Volume Ratios, including the prior quarter's roll trading.

The CME Globex Messaging Policy creates fair business guidelines by which customers are billed a surcharge for overly high message rates. Under the CME Globex Messaging Policy, each clearing member firm (active or inactive clearing member firms which maintain relationships with CME Clearing) must not exceed product-specific benchmarks, tailored to the valid trading strategies of each market. CME Group calculates benchmarks based on a per-product Volume Ratio.

CME Group is currently reviewing the CME Globex Messaging Policy and information regarding any future changes will be available announced via the Globex Notices.
