Notice Number	04-134
Effective Date
On Monday August 2nd, CME will launch trading in Eurodollar options on the new Enhanced Options System. During daytime hours (Chicago time) – from 7 a.m. to 4 pm on Monday through Friday – Eurodollar options will trade electronically on the new system. Outside these hours – from 5pm to 6:50 am Sunday through Thursday – these options will trade on GLOBEX. Open-outcry trading of Eurodollar options during pit hours will continue unaffected. There are no clearing system or bookkeeping system changes associated with the launch of the Enhanced Options System. Trades in Eurodollar options will appear in the Front-End Clearing (FEC) system exactly like trades executed on GLOBEX, and firms will receive TREX trade confirmation messages for them exactly like those for trades executed on GLOBEX. Trades in option strategies will be broken out into individual legs, and firms will receive trade confirmation messages for each leg. For complete text of Clearing House Advisory 04-134...
