CME Globex Notices: April 21, 2008

Book Depth Change for U.S. Treasury, Swap and Fed Fund Options
Effective Sunday, May 4 (trade date Monday, May 5), in response to customer requests, the market data book depth for all U.S. Treasury, Swap and Fed Fund options on futures on Market Data Platform channel 116 will change to three deep. Currently, these markets only support top-of-book market depth.

This change will impact both the FIX/FAST- and RLC-format market data books. The complete list of impacted products is available  below.

For FIX/FAST, this change will result in a move to the incremental book management style from the current overlay style, as reflected in tag 279 MDUpdateAction in the Market Data Incremental Refresh message (tag 35=X). Valid values for this tag will now include 0 (New), 1 (Change) and 2 (Delete).

The book depth for every instrument on CME Globex is detailed in tag 264 MarketDepth in the Security Definition (tag 35=d). CME Group strongly recommends customer applications utilize tag 264 to identify the supported instrument book depth level dynamically. CME Group also recommends all customer applications should be designed to leverage all possible values for tag 279 MDUpdateAction in the Market Data Incremental Refresh message (tag 35=X) for all markets and channels, to minimize the impact of future book depth changes.

The FIX/FAST Software Development Kit, including details on book management in the Core Functionality module, is available   online. Please contact Customer Support for Electronic Trading (CSET) at 312.930.2322 for development assistance.

This book depth change is now available for customer testing in New Release.

Request for Cross on CME Globex 
Effective Sunday, May 11 (trade date Monday, May 12), the method for submitting a Cross order on CME Globex will change for legacy CME Commodity, FX and Equity options to use the New Order Cross (FIX tag 35-MsgType=s) message. Currently, these products use the Quote Request (tag 35-MsgType=R) message with tag 54-Side=8.

With this change, the Quote Request method for cross orders will no longer be supported on CME Globex.

Please note: legacy CBOT options remain ineligible for Cross orders on CME Globex.

In addition to the technical changes, the regulatory requirements and process will also change. More information is available in the  Regulatory Advisory.

Cross order eligibility is defined in positions 789, RFC Eligible Flag, and 800, RFQ for Cross Eligible Flag. For more information please review the Cross Order section of the  Options module of the iLink SDK.

These products with RFC eligibility will be available for customer testing in New Release Monday, April 21. Customer applications are required to certify for the New Order Cross message before submitting cross orders in production. Please contact your trading application provider for more information.

Eurodollar Options Strategies on CME Globex
Effective Sunday, May 18 (trade date Monday, May 19), the Eurodollar options strategies instrument management will change to allow CME Group to eliminate strategies that, due to market movement, are outside the listing range. Currently, all strategies once listed are maintained through to expiration regardless of market activity. This change will allow CME Group to better manage the volume of listed instruments, in response to customers' concerns about the weekly instrument download.

This is the process currently in place for Equity options strategies. The new elimination process only applies to Eurodollar options strategies; there is no change for option outrights, futures or future spreads.

Any orders submitted for an eliminated strategy instrument will be rejected by CME Globex.

Customers can use User-Defined Spreads (UDS) functionality to create and trade any desired options strategy. Please contact your front-end system provider for more information.

CME Group recommends all customers purge and re-load their instrument databases weekly from the FIX/FAST Security Definition or RLC Instrument Creation (MO) market data messages every week. There is no impact for customers who follow this recommendation; by completing a weekly refresh you will capture the current listed instruments. Please contact your front-end system provider for more information.

This change is currently implemented in New Release.

 Matching Algorithm Changes for Legacy CBOT Interest Rate and Commodity Futures
In response to customer feedback and in the interest of the market, CME Group will revise the Split FIFO/Pro Rata (K) allocation algorithm for selected CBOT markets. With this change, the pro rata allocation matching behavior will more closely follow the behavior of that on e-cbot by allocating a quantity of one contract to orders that have an allocation value of less than one (the amount calculated to allocate). The revised K algorithm will also be applied to additional products, as detailed below. Currently, the K algorithm is only applied to the 2-Year U.S. Treasury Note futures.

The Split FIFO/Pro Rata algorithm assigns TOP priority to an order that

betters the market, and meets the minimum volume threshold.

The Split FIFO/Pro Rata algorithm also establishes a volume cap that limits the quantity a priority order can receive.

Allocation Sequence

TOP Order percentage Allocation (with Minimum/Maximum) LMM Remaining quantity split - X% FIFO, X% Pro Rata (fields must sum to 100%) X% FIFO (based on remaining quantity * FIFO %) Pro Rata with Min (based on remaining quantity * Pro Rata %) Pro Rata Leveling (new allocation) Timestamp Priority (any remainder from Pro Rata)

If a product does not have any registered LMMs, the LMM allocation is skipped. The FIFO percentage in the third allocation may be set to zero, which will result in a 100% Pro Rata with Min allocation. Only the 2-Year Treasury Note futures have a FIFO allocation at the third step.

The new Pro Rata Leveling component within the K algorithm will also be applied to other products on the following schedule:

May 4

2-Year Treasury Note futures, legs and spreads Legacy CBOT Agricultural futures, legs and spreads

May 9

5-Year Treasury Notes futures calendar spreads 10-Year Treasury Note and 30-Year Bond futures Reduced Tick Spreads

May 18

5-, 10- and 30-Year Interest Rate Swap futures, legs and spreads

Late June

Fed Funds futures, legs and spreads

More information on this algorithm, including allocation examples, is available in the  CBOT Merger Client Impact Assessment.

Customers can determine the matching algorithm assigned to each product from FIX tag 1142-Match Algorithm, in the FIX/FAST Security Definition (tag 35=d) market data message.

Butterfly and Condor Spreads for KCBT and MGEX Futures
Effective Sunday, May 18 (trade date Monday, May 19), Butterfly (Strategy Type Code BF) and Condor (CF) future spreads listings will be expanded on the following products:
