As a reminder, on December 1, 2007 we will complete the parallel production migration period of CME Globex market data in ITC format.   At this time Channel 4-6 will be decommissioned and will be replaced by Channels 200-207.  

With this change customers can expect to see an additional change within all messages for FX Options.  Specifically, Channel 5 displays an ‘A’ for American style for options regardless of if they are European or American style.  With these channel changes, customers will see an ‘E’ for European Options and an ‘A’ for American Options over Channel 205.
