Cash-Settled Cheese Futures and Options

The Cheese futures will complete the dairy crush with which the original commodity as well as its product and byproducts can be hedged.

The Cash-Settled Cheese product is currently available for customer testing in New Release.

 FIX tag 1147-UnitofMeasureQty and tag 996-UnitofMeasure
Starting Sunday, July 11, the values in FIX tag 1147-UnitofMeasureQty and tag 996-UnitofMeasure will be updated for the following futures listed on CME Globex. These tags are currently sent in the Security Definition messages; this launch is designed to make the values for futures accurate and consistent.

Please note: CME Group recommends tags 1147 and 996 only be used for futures and variable quantity products. The information in these tags is not supported for options and future spreads.

Tags 1147 and 996 are sent in the SecurityDefinition message (tag 35-MsgType=d) and are used together to determine the contract size for the futures instrument. For example, for a Eurodollar futures contracts, tag 1147-UnitofMeasureQty=1000000 and tag 996-UnitofMeasure=USD indicate a contract size of USD $1,000,000. More information on these tags is available in the  FIX/FAST Message Specifications and, for variable quantity products, in the  Variable Quantity Client Impact Assessment.

With this launch, the following valid values will be added for tag 996-UnitofMeasure:

• ALLOW – Allowance
• CER – Certified Emission Reduction units
• CRT – Climate Reserve Tonnes
• MTONS – Metric Tons

The following values will no longer be valid for tag 996-UnitofMeasure:

• CHIIP – Carville-Hurricane Index Percentage
• CHIP – Carville-Hurricane Index Percentage
• DEM – Deutsche mark
• GRAMS – Grams
• METON – Metric Tons
• MP – Mexican Peso
• TRY – Turkish lira

 3-Deep Options Market Data
Effective Sunday, July 11, in response to customer requests, the market data book depth for the NYMEX Crude Energy (channel 35) and COMEX Metals (38) options channels will change to three deep. Currently, these markets only support top-of-book market depth in FIX/FAST.

On Sunday, August 22, the market data book depth for the remaining top-of-book only options channels, CME Interest Rates (10), CME Commodity (14), Non-Crude Energy (36), NYMEX Alternative Markets (37), CBOT Commodity (112) and MGEX (119), will change to three deep.

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-MsgType=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 Certification Support for Electronic Trading ( CSET) at 312.930.2322 for development assistance.

Implied Functionality for CBOT Corn Futures 
As previously announced, effective August 29, 2010, implied functionality will be disabled for CBOT corn futures and spreads (tag 1151-SecurityGroup=ZC).

Implied functionality is being disabled in the CBOT Corn futures from August 29, 2010, through December 31, 2010, to determine if more robust markets in highly liquid contracts can be improved without the implied spreads. We will monitor the market during this period for signs of market quality degradation and, if observed, we will reinstate the implied functionality. Based on the assessment over this period, a decision on the use of the implied spreading functionality for corn futures going forward will be made. More information on this change is available  online.

Implied functionality is indicated for every instrument on CME Globex in the FIX/FAST Security Definition message (tag 35-MsgType=d), in tag 1144-ImpliedMarketIndicator.

Customer iLink and Drop Copy Production IP Address Migration
