To CME^® Globex^® Customers:

Effective Sunday, February 13, 2005, CME will begin trading equity options on CME E-mini^™ Russell 2000^® futures (“ER”) and five ER option spreads on CME Globex^®: butterfly, horizontal, strangle, straddle and vertical spreads.

These new ER options and spreads will be available for testing in the CME certification environment starting Sunday, January 30, 2005.

For all CME Market Data API (MD API) and CME MDN users subscribing to RLC messages, please see below:

The new CME E-mini Russell 2000 options and spreads will be published on the CME MD API options subject of CME_GB2_OPT. All CME MD API 2.0 users who have elected to “opt in” and subscribe to options market data, will receive the new options contracts as part of an MO request starting Sunday, January 30, 2005. Those who use the MO request functionality by subject as part of CME MD API 2.1, only receive those specified in the MO request subject.

In preparation for the launch, CME will be adding the spread instruments (2,020 additional MO messages) beginning Sunday, January 30, 2005, into production. For CME MD API users that employ a timeout value as part of the MO request, CME recommends increasing the timeout value to 5 minutes. Please note that Instrument Type D was formerly used exclusively for futures spreads and is now also used for options spreads. The RLC instrument type and strategy type codes for these spreads are as follows:

*The option vertical spread strategy code is “VT”; however, the CME Globex Symbol uses VC (Calls) and VP (Puts).

Each CME Globex listed spread has its own specific MO Message. Within each option spread MO message, each leg of the spread will be identified, including its own specific ISIN Code. For the Butterfly Call example below, the ER:BOH5C150_200 spread’s MO message also contains the three legs’ ISIN Code. In this example; Leg1 = ISIN for ERH5_C6150, Leg2 = ISIN for ERH5_C6175, and Leg3 = ISIN for ERH5_C6200.

For the RLC CME Globex symbol conventions, here are examples of the contract names for the option spreads. An underline = space:
