Effective Sunday, November 18, 2007 , CME Group is introducing new Instrument Creation (MO) Replay channels on the Market Data Platform (MDP) in the production environment.  Each RLC product data channel (e.g., channel 7, Equity futures; channel 8, Equity options, etc.) will have its own dedicated MO Replay Channel, enabling customers to listen only to the MO messages for which they receive market data.

The existing MO Replay channels (channels 1 and 16) will be maintained in parallel for at least an eight week period before those channels are decommissioned.

Please note:  These changes affect only RLC-format channels.  ITC 2.1-format channels are unaffected.

Testing Availability

These new replay channels will be available for customer testing in the New Release environment on Thursday, October 4, 2007, and in the Certification environment on Wednesday, November 21, 2007.
