In an effort to simplify and improve Globex order processing, effective Sunday, July 9, 2006 (trade date Monday, July 10, 2006), CME will reduce the maximum number of quotes a market maker can submit in a single Mass Quote message to 100,from the current maximum of 195.  Mass Quoting functionality is supported in CME Equity, FX, and Interest Rate options products.

This change to the Mass Quote message is currently available for testing in the CME certification environment.
