As you are aware, the CME is about to participate in the launch of two new innovative and exciting products; Single Stock Futures and TRAKRS. To that end, there are a few programmatic changes to our key files that clearing member firms use for bookkeeping. The Trade Register and the TREX confirmation records. We provided a link to these revised layouts on our web site. In addition, we have listed the changed fields in the attached notice for your information. We will also be sending you an updated notice very soon with information on obtaining sample test files.

You want to note that the SSF trades will sort separately on the Trade Register report at the end of the futures section and before the options section. 

If you have any questions in regard to changes in these layouts, or the new Daily Adjustment File for TRAKRs, please call one of the following Client Management staff; Karen F. McCoy at 312 930 4524 or Stacey Jurek 312 338 2088.

Thank you.
