Final Phase: Changes to iLink On-Demand Party Details for Order Mass Cancel - November 1

On Sunday, November 1 (trade date Monday, November 2), CME Group will continue implementing iLink messaging changes to on-demand administrative information for the iLink Order Mass Action Report (tag 35-MsgType=BZ) to consistently return customer account information.

On-Demand Party Detail Definition Request Acknowledgment

Population of tag 1691-PartyDetailID for the Customer Account Party Detail Role (tag 1693-PartyDetailRole=24) on the Party Details Definition Request Acknowledgment (PDDRA, tag 35-MsgType=CY) will always reflect the value from the Party Details Definition Request (PDDR, tag 35-MsgType=CX).

Currently, the tag 1691-PartyDetailID on the PDDRA is populated only when tag 6115-MassCancelRequestType=101 (Account) is sent in the Order Mass Action Request (tag 35-MsgType=CA).

iLink Party Details Definition Request Acknowledgment
Tag 1693-PartyDetailRole	Submitted Tag 1691-PartyDetailID	Submitted tag 6115-MassCancelRequestType	Current Return Tag 1691-PartyDetailID Value Behavior	New Return Tag 1691-PartyDetailID Value Behavior
24 (Customer Account)	ABCDE	≠ 101	Not Present	ABCDE
ABCDE	= 101	ABCDE	ABCDE

This change is only applicable to on-demand administrative information. Pre-Registered Party Detail Definition Request Acknowledgment messages sent from the Order Entry Service Gateway remain unchanged.

TransactTime Precision Update

With this change, tag 60-TransactTime on the iLink Order Mass Action Report (tag 35-MsgType=BZ) will be sent with nanosecond precision. This timestamp is currently sent in milliseconds.

iLink On-Demand Party Details for Order Mass Cancel and TransactTime Precision changes Launch Schedule

NewImplied Functionality Extension for Calendar and Butterfly Spreads on CME Globex - November 15

Effective Sunday, November 15 (trade date Monday, November 16), CME Group will extend implied trading functionality on CME Globex to support Butterfly (BF) and Calendar (SP) spreads with mixed tick legs for select Short-Term Interest Rate futures. This initiative is designed to facilitate price discovery and order matching efficiency.

This enhancement expands functionality to generate implied liquidity across Calendar and Butterfly spreads where some legs have smaller tick increments (e.g., 0.25) than other legs or the spreads themselves (e.g., 0.50):

• Calendar Spreads (SP): Extends implied calculations to Calendar Spreads where the spread and Leg 1 trade on a smaller tick increment (e.g., 0.25) while Leg 2 trades on a larger tick increment (e.g., 0.50).
• Butterfly Spreads (BF): Extends implied calculations across Butterfly Spread types featuring mixed-tick leg and spread combinations (e.g., spread/Leg 1 on 0.25 tick; Leg 2/Leg 3 on 0.50 tick).

While there are no iLink or MDP 3.0 message schema updates or tag changes for this launch, clients are encouraged to test implied order execution, rounding, and fill processing for both SP and BF spreads in the New Release environment prior to launch. The following behavioral changes will be visible on iLink execution reports and MDP Trade Summary messages:

• Calendar Spread Implied Behavior: Off-tick implied calculations on Leg 2 for calendar spreads are rounded down for bids and rounded up for asks to the nearest valid leg tick (e.g., an implied bid calculated at 9994.75 on a 0.50 tick leg rounds down to 9994.50).
• Butterfly Spread Execution Behavior: Split-price fills on Leg 2 and off-tick leg fill prices in iLink Execution Reports (tag 31-LastPx) for multi-spread matches (e.g., BF with SP1 and SP2).

For complete technical specifications, pricing logic, and message examples, review the client impact assessment.

As a result, the planned migration of Livestock markets to the Production-Dallas environment is no longer necessary.

The Sandbox-Dallas environment is still available for client testing. To ensure a smooth, trouble-free migration, the Sandbox environments serve as your essential proving ground, allowing clients to de-risk the upcoming migrations and ensure trading operations are ready for launch.

Updated Migration Roadmap

Mid-2027

• Private Google Cloud Chicago Region
  • Sandbox-Chicago: Clients begin Sandbox-Chicago testing via GLink ULL and GLink Premium access from Ultra Low Latency U4C Bare Metal and U4S Virtual Machine instances.

Starting late 2027 and continuing through 2028

• Private zones of the Google Cloud Dallas Region
  • Production-Chicago: CME Group begins moving markets from the current data center to the Google Cloud Chicago region.

End of year 2028

• Physical co-location update
  • CME Group will announce the physical co-location site plans for both GLink Aurora and Customer Hardware Co-location (CHC)

  • Disaster Recovery-Dallas: Disaster Recovery for Globex markets migrates to private zones of the Google Cloud Dallas region. The current Disaster Recovery environment in New Jersey will be decommissioned.

Listed Derivative markets on the CME Globex platform are migrating to Google Cloud’s Ultra Low Latency (ULL) Solution to deliver a more flexible, scalable, and resilient trading ecosystem for clients. By combining Google Cloud’s ULL infrastructure with industry-leading Globex execution capabilities, this transition will unlock expanded co-location options, real-time data analytics, and enhanced operational efficiency to better support your needs.

Maintaining market integrity and operational continuity remains our highest priority; we are dedicated to supporting you throughout every phase of this migration with robust testing sandboxes, transparent roadmaps, and dedicated support to deliver a reliable transition.

Position Reporting Under CFTC Part 17

On April 30, 2024, the Commodity Futures Trading Commission ("CFTC") approved final rules to amend its Large Trading Reporting Regulations for Futures and Options. The amendments were made to modernize CFTC's Large Trader Reporting process and align it with other reporting structures outlined in CFTC regulations.

Since October 2024, CME Group has offered methods to retrieve its instrument listing containing the Unique Instrument Code (UIC) and other instrument data elements in compliance with the amended rule.

Starting March 10, 2025, CME Group began accepting test files in the new Position Message FIXML format via SFTP. For details regarding submitting the new FIXML Position Message, file management, field validations, and example scenarios, please refer to the information in the CME Group Client Systems Wiki.

CFTC's final rules became effective upon publication in the Federal Register on June 3, 2024. Subject to the conditions of the January 27, 2026, no-action letter, reporting firms must comply with these CFTC regulations by July 26, 2027.

A test environment for Large Trader Reporting is now available within the Firm Regulatory Portal (FRP UT). Users can access the testing portal at: https://frp.uat.cmegroup.com.

A brief video demonstration is available to highlight the new look and functionality of the FRP UT.

The Market Regulation Department will be publishing further guidance regarding Large Trader Reporting in subsequent Special Executive Reports as solutions become available.
