Reminder: NYMEX Products on the CME Market Data Platform  
Effective Sunday, May 6, 2007, CME is decommissioning the legacy NYMEX market data channel (20) on the CME Market Data Platform.

Since the introduction of NYMEX futures and spreads on the CME Globex platform, market data messaging rates on the CME Market Data Platform NYMEX channel (20) have steadily increased, recently reaching peaks greater than 3 mbps. To better manage bandwidth utilization, CME leveraged the scalability of the CME Market Data Platform and introduced three new channels for NYMEX and COMEX ^® products.

Complete information on the three new NYMEX and COMEX channels on the CME Market Data Platform, including the products assigned to each channel, is available online.

More information on NYMEX and COMEX products on the CME Globex platform is available at www.nymexoncmeglobex.com.
