CME Globex Notices: March 7, 2011

CME Globex Performance Enhancements for Equity, FX and Agriculture Futures
CME Group is implementing an upgrade to the following futures markets on the CME Globex electronic trading platform that will result in significantly reduced message response times. Already among the fastest in the industry, in internal testing environments this upgrade reduced iLink and FIX/FAST response times by an average of 10%.

• Sunday, March 20
  • CME Equity futures and future spreads
  • CBOT Equity futures and future spreads
• Sunday, March 27
  • FX futures and future spreads
• Sunday, April 3
  • CME Agriculture futures and future spreads
  • CBOT Agriculture futures and future spreads

Please note: as a result of the reduced message response times, bandwidth utilization in these futures markets is expected to ultimately increase by as much as 10%. There will be no changes to functionality or messaging format with these performance improvements. Good 'Till Cancelled and Good 'Till Date (GTC/GTD) orders will not be impacted. This upgrade is designed to enhance our liquid, efficient and competitive marketplace for participants worldwide.

FIX/FAST Settlement Enhancements
Effective Sunday, April 3, FIX/FAST settlement enhancements will launch on CME Globex.

• Actual Preliminary
• Rounded Preliminary
• Final
• Theoretical Final

This launch will impact the settlement data blocks on Market Data Incremental Refresh (tag 35-MsgType=X) and Security Definition (tag 35-MsgType=d) messages. Details on the enhancements are available in the   Client Impact Assessment.

In addition, the following tag values will no longer be sent in the Market Data Incremental Refresh (tag 35-MsgType=X). As of this release, customer system must not rely on these values:

• tag 269-MDEntryType=M (Prior)
• tag 286-OpenCloseSettleFlag=4 (Price entry from previous day)

Certification is not required and there are no new templates. Customers and system providers are encouraged to test the enhancements thoroughly in New Release starting on Monday, February 21.

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.
