Critical Updates

Mass Quote Protection Enhancements - June 30

Effective Sunday, June 30 (trade date Monday, July 1), in addition to the current Mass Quote Protection (MQP) types, CME Group will offer the new Fill % (F) MQP type at the Group Code and Product Line levels.

Mass Quote Protection Enhancements
New MQP Type	Definition
Fill % (F)	Fill % (F) will be the cumulative sum of each quote's execution quantity relative to its original quote quantity during a single MQP duration. Tallies each time a quote's bid or ask trades Example:  A bid-side quote quantity =10 trades as a partially fill for 2.  The remaining (resting ) bid-side quotes quantity = 8  and the Fill % (F) MQP tallies to 20%. MQP functionality will be triggered after the cumulative Fill Percentage exceeds the Fill % (F) threshold.

Please note: Fill % (F) will default to a null value. If utilized, the value will default to 90%. Customers can only edit it to a value more than 90%.

More information about the new MQP type is available in the client impact assessment.

Certification for the new Fill % (F) MQP type is not mandatory for client systems already certified for the Mass Quote suite.

The new MQP Type is currently available in New Release for customer testing.

Current MQP Type Decommission

Effective Sunday, October 13, the following MQP types will be decommissioned:

• New Quote Fill (X)
• Execution (Y)
• Buy/Sell (Sides)
• Delta (D)

Please Note: CME Group will continue to support the existing MQP type - Traded Quantity (Z).

The current and new MQP types will be supported in parallel as follows:

MQP Types	Currently	June 30	October 13
New - Fill % (F)	Not Available	Supported	Supported
Traded Quantity (Z)	Supported	Supported	Supported
New Quote Fill (X)	Supported	Supported	Decommissioned
Execution (Y)	Supported	Supported	Decommissioned
Buy/Sell (Sides)	Supported	Supported	Decommissioned

Balanced Strip Butterfly Spread on CME Globex - July 28

Effective Sunday, July 28 (trade date, Monday July 29), a new exchange-defined Balanced Strip Butterfly futures spread will be made available for trading on CME Globex. The new spread will utilize a new strategy type (BB).

Revised CME Globex Messaging Efficiency Program and Resources - October 1

Effective trade date Tuesday, October 1, CME Group will revise the CME Globex Messaging Efficiency Program (Program) to more effectively target messaging that can negatively impact system performance, impair efficient access to the market, and create unnecessary infrastructure and processing costs for market participants.

The existing Program will remain in effect through Monday, September 30, and will be retired when the revised Program is implemented on Tuesday, October 1.

The following changes will be made under the revised Program:

• Message scoring will be calculated and applied for the entire CME Globex trading session versus the current hours between 7:00 a.m. – 3:15 p.m. Central Time (CT)
• Previously excluded instruments and back months will be included and scored at a reduced weighting

To account for these changes, messaging tiers will be expanded.

To assist potentially impacted firms on a T+1 basis following the conclusion of trade date July 1, CME Group will notify assigned messaging contacts of any instances where product group benchmarks have been exceeded using the revised Program scoring methodology.

For more information, view CME Globex Messaging Efficiency Program Resources such as:
