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.

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.

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:
