To support future enhancements for futures and options markets on CME Globex, the MDP 3.0 SBE core schema will be updated to version 13 starting Sunday, October 13, 2024 (trade date Monday, October 14, 2024), and concluding Sunday, January 12, 2025 (trade date Monday, January 13, 2025).

Futures and options on CME Globex is currently utilizing core schema version 9. To ease customer development efforts, the new SBE schema files will support template extension for MDP 3.0 messages. For client systems that do not support template extension, the schema update is not backward compatible, and the MDP 3.0 messages sent from CME Globex cannot be decoded.

In conjunction with the core schema futures and options update, the futures and options markets will leverage a new separate schema dedicated to TCP recovery for UDP.  

This topic provides an overview of concepts with which clients must be familiar to process the new futures and options SBE market data and Global TCP schemas.

Testing and Certification

Certification is optional.

SBE Schema Update

A new Simple Binary Encoding (SBE) incremental schema version will be sent on all futures and options market data channels. The new schema will be incremented from version 9 to 13. The new schema for New Release can be found on FTP/SFTP site. The new fields are future use and will not be populated with the schema launch.  More information regarding these enhancements will be published in a future CME Globex notice. 

To facilitate customer development efforts, the new SBE schema will support Template Extensions. For client systems who do not support template extension, the template is not backward compatible and the MDP 3.0 messages sent from CME Globex cannot be decoded.

Non-Impacting SBE Template Updates

The following new SBE templates will not be utilized on futures and options CME Globex market data channels. 

TCP Recovery for UDP Schema Update

With this release client systems that support TCP Recovery for UDP must migrate to a separate dedicated Global TCP Recovery SBE Schema for UDP.  Therefore, with this release client systems that utilize MDP TCP recovery must support both the Core Globex and Global TCP Recovery SBE Schema for UDP SBE schemas.  The Global TCP Recovery schema is already in use for EBS, Brokertec, Data Insights and Streamlined Market Data. This change does not support template extension.

CME provides an FTP (https://www.cmegroup.com/ftp) and SFTP (sftpng.cmegroup.com) site to disseminate MDP 3.0 schemas. CME Group recommends clients use SFTP over FTP to access configuration files.  See the available FTP schema file location for TCP Recovery SBE Schema for UDP. 

Template Mapping

The table below outlines the template mapping between the current v9 core schema templates and the new Global TCP Recovery SBE Schema for UDP.
