CME STP messages and functions are made available using industry standard FIX and FIXML formats with custom CME Group extensions.

  • CME STP FIX - A standard FIX 4.4 API which supports Query, Subscriptions and message Streaming with custom CME extensions over TCP/IP.

  • CME STP FIXML - Simply called CME STP, is built upon Representation State Transfer (REST) web service technology. With this technology, HTTP URLs and methods (GET, POST, etc.), parameters, and statuses are used to model the remote procedure call behavior. 


The Core FIX & FIXML Specifications are separate topics to differentiate the technical implementations.

The Business Messages Specifications for FIX and FIXML are in a single table for different Markets.

Certification is performed using AutoCert+, an automated testing tool for validating client system functionality and is designed to verify application behavior and conformance with CME Group requirements to ensure messaging and processing reliability and the capability to recover from abnormal message processing events.
