CME is introducing the CME Market Data Platform, a new market data dissemination method, early in the third quarter of 2005.  The new platform will consolidate the existing CME Market Data API and CME Market Data Network, but will maintain the existing market data message formats.  The new CME Market Data Platform will require less bandwidth and allow for superior scalability.

For an overview of the new platform, please review the Introduction to CME Market Data Platform, located at http://www.cme.com/files/Intro_MarketDataPlatform.pdf

Detailed development documentation will be available in April.

The CME Market Data Platform will be a primary topic at the upcoming CME Electronic Trading Customer Forums:

Tuesday, April 12                                Chicago                                   4:00 p.m.

Thursday, April 14                               New York                                 5:00 p.m.

Further details for these meetings will be sent soon.  In the meantime, if you have any questions, please contact:
