      Effective today, July 28, 2009, the message enhancements to the Market Data Incremental Refresh messages (tag 35-MsgType=X), listed in the notice below, have been removed from the following channels due to price formatting issues. The new implementation date for these channels will be announced via the CME Globex and Market Data Notices.

      The new message enhancements remain in production for all other channels.

      There are no template changes required for this rollback.

      On Sunday, July 26, 2009, (trade date Monday, July 27), enhancements for the Market Data Incremental Refresh (tag 35-MsgType=X) messages were launched to facilitate the conversion of ITC messages to FIX/FAST format for CME Globex market data. These enhancements required a new template. The following data are now included in Incremental Refresh messages:

      • Theoretical Settlement Data Block
      • Open Interest Data Block
      • Cleared Volume Data Block
      • Fixing Price Data Block

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

      More information on these changes to the Incremental Refresh messages, and the elimination of ITC 2.1, is available   online.
