Mandatory Migration - iLink 3 Binary Order Entry Protocol for CGW - January 28

• More efficient iLink FIX messaging
• Standard message size, fixed positions, and fixed length fields

The Client Impact Assessment is available and provides detailed functionality and messaging information.

Based on customer feedback and to better align with iLink 2 CGW, Cancel on Disconnect (COD) will be optional functionality for all iLink 3 CGW sessions. Customers will be able to request COD functionality to be disabled or enabled in:

• New Release – Now available
• Production – Now available

Please note that all iLink 3 CGW sessions will be created with COD enabled. Clearing Firm Administrators can disable COD functionality by entering the change request via Firm Admin Dashboard (FADB).

AutoCert+ certification is required for all client systems using CGWs.

• Now Available – iLink 3 CGW functionality available in New Release and AutoCert+ certification  
• January 6 - The OESGW configuration information (i.e. OESGWs and IPs) for CGWs will be added to the production config.xml file via an SFTP site (sftpng.cmegroup.com).

Drop Copy Impacts - Mandatory iLink 3 Binary Order Entry Protocol for Convenience Gateway - January 28

On Sunday, January 28 (trade date Monday, January 29), CME Group will launch the iLink 3 protocol on existing Convenience Gateways (CGW) for trading futures and options on CME Globex. All customers connected via Convenient Gateway (CGW) are encouraged to migrate to iLink 3 as early as possible prior to the iLink 2 decommission. Key events and dates are available.

Impacts of mandatory iLink 3 Binary Order Entry protocol for Convenience Gateway on Drop Copy Convenience Gateway target sessions.

• Message encoding: The Drop Copy encapsulated XML Non-Fix (tag 35-MsgType=n) Message payload sent from iLink 3 source sessions will be in ASCII format.
  • Message payload mapping conforming to the iLink 3 formats and encoding will feature deprecated message tags, additional tags and enumerations for order entry, clearing and regulatory compliance messaging specifications.
  • A summary of ASCII encoded tags with their equivalent values in Simple Binary Encoding tags and enumerations is available.
• Target Session: Current Drop Copy CGW target session users do not need to request new target sessions although upon requesting the mandatory iLink 3 source session, a new target session may be automatically created to accommodate iLink order entry infrastructure load balancing and optimization considerations. Customers are requested to check for new automatically generated Drop Copy CGW target sessions.
• Parallel period: During the parallel period which runs until December 31, 2024, CME Globex will support Drop Copy target sessions connected to both iLink 2 and iLink 3 CGW sessions. When iLink 2 is decommissioned on December 31, 2024, any Drop Copy target sessions with iLink 2 sessions only will be removed from the platform.
• AutoCert+ Certification: Certification is not required for existing Drop Copy CGW session users.

Please review Mandatory iLink 3 Binary Order Entry Protocol for CGW for additional details.
