This advisory contains information for week 4 test cycles. There will be two cycles, on Tuesday, September 13, 2005 and Thursday, September 15, 2005. Attached are test scripts locations, a schedule of the test dates and trade entry times available to testing firms. In this cycle, firms will have the opportunity to submit and match block trades in the new “mid-season” weather futures and options, the first CME products to use 3-byte codes. Firms may submit trades via the Front-End Clearing (FEC) browser-based user interface, and receive TREX confirmation messages for their matched trades to load to books. Firms will also be able to receive TREX electronic-trade confirmation messages for mid-season weather futures and options executed on CME Globex. For Full Text Of This Advisory........
