Elimination of Exchange-Defined Options Strategies on CME Globex
To allow more time for trader education and systems' readiness, CME Group has postponed the planned delisting of all options EDS until November 1, 2009.

CMEG currently prelists approximately 360,000 options spreads per week, known as Exchange-Defined Spreads (EDS). Less than 1% of the more than 360,000 EDS have activity. Due to customer and system provider demand, CMEG has chosen to remove all EDS and make all option strategies user defined. A User-Defined Spread (UDS) is an option spread that a trader creates by defining the spread's legs and ratios. CME Globex receives these legs and creates a tradable instrument that is disseminated to the entire market. If the created spread matches a known CMEG spread type (e.g., straddle), CME Globex will properly identify the spread as that type.

November 1
Horizontals (HO) UDS will be harmonized so all product complexes have the same construction:

• Buy deferred front leg with strike 1
• Sell near back leg with strike 1

This will be a change for Equity, Commodity, NYMEX and COMEX options markets, and the pricing will be reversed from the current convention in these markets. With this change, all existing horizontal UDS in the Equity, Commodity, NYMEX and COMEX options markets will be removed.

Diagonal (DG) UDS will be added as a recognized UDS spread type in all CME Globex options markets:

• Buy deferred front leg with strike 1
• Sell near back leg with strike 2

The horizontal harmonization and the new diagonal recognized UDS spread type are currently available for customer testing in New Release.

CMEG will add the following recognized UDS spread types:

• Jelly Roll
• Iron Butterfly
• Guts
• 3-way
• Straddle vs. Call
• 3-way Straddle vs. Put

CMEG will no longer pre-list any options spreads. Existing EDS will be removed, and no new EDS will be added. All option spreads must be created by traders using their trading software's UDS functionality.

All system providers that support option spreads must have developed to the UDS functionality properly identifying UDS' that match CMEG recognized spread types.

These new recognized spread types are currently available in New Release.

The following resources are available for UDS functionality:

• Client impact assessment - detailed UDS development information
• iLink order entry UDS specifications (Section 6, p. 40)
• FIX/FAST market data UDS impact - development information for options market data
• A list of all CMEG recognized spread types in Electronic Trading Concepts

iLink tag 48-SecurityID Change
Effective Sunday, November 8, 2009, FIX tag 48-SecurityID in iLink messages will be changed to match the current format and data type of tag 48-SecurityID in the FIX/FAST market data messages.

This harmonization of tag 48-SecurityID will provide customers a key for linking FIX/FAST and iLink messaging for a particular instrument.

With this launch, CME Globex will always send the new format for tag 48 in iLink, even if customer systems submit the old format. For instance, if the customer submits a new order with tag 48=CME009606070, CME Globex will respond with tag 48=96

The tag 48 harmonization is currently available for customer testing in New Release.

Energy Inter-Exchange Spreads on CME Globex
Effective Sunday, November 15, 2009 (trade date Monday, November 16), four NYMEX-DME implied inter-exchange spreads will be listed for trading on CME Globex.

Inter-exchange spreads are implied futures spreads in which the two legs originate from different exchanges. They consist of buying the front leg (exchange A) and selling the back leg (exchange B), with both legs having the same maturity. For inter-exchange spreads, tag 762-SecuritySubType will be set to IS. Inter-exchange spreads are implied IN and OUT, from the individual legs IN to the inter-exchange spread or conversely from the inter-exchange spread OUT to the respective future outrights. These will be the first inter-exchange spreads listed on CME Globex.

This launch will impact all customers receiving FIX/FAST market data, even if you do not plan on supporting the new spreads. There will be a new FIX/FAST template for the Security Definition (tag 35-MsgType=d) message for this launch. The new template is now available in the production folder of the CME Group ftp site. Per the normal process, the current template is still available as well.

The messaging and functionality impacts are documented online in the Client Impact Assessment. This launch is currently available in New Release for customer testing.

iLink Enhancements for FIX tags 151-LeavesQty and 14-CumQty
Effective Sunday, October 4, 2009, the FIX tags 151-LeavesQty and 14-CumQty were modified only for Execution Report-Acknowledgements on Cancel/Replace Requests with In Flight Mitigation (IFM) enabled. These changes only apply to Equity and FX futures, and to all options markets.

Previously, when a customer submitted a Cancel/Replace Request with IFM on an order that is partially filled, tags 151 and 14 in the Execution Report-Acknowledgement were not populated correctly.

With this change, when a customer submits a Cancel/Replace Request with IFM on an order that is partially filled, the Execution Report-Acknowledgement correctly includes:

• The remaining working quantity of the Cancel/Replace order size (minus the partially filled quantity) in tag 151
• The cumulative quantity traded in tag 14
