CME Straight Through Processing (CME STP) enables customers to connect to the Exchange to retrieve FIXML 5.0 SP2 post-trade messages containing NYMEX, COMEX, Gulf Mercantile Exchange (GME), CBOT via CMD, and CME cleared trade information. The CME STP solution focuses on end-to-end trading customer interfaces for all markets and provides real-time trade flow between the front and middle office.

The Exchange requires a basic working knowledge of FIXML to interface with CME Straight-Through Processing API (CME STP). Information on FIX protocol and access to the FIXML 5.0 SP2 specifications are located at

Trades that occur on CME ClearPort and CME Globex will not make the opposite broker of the trade available due to the competitive fairness in the market place rule.

Supported Clients

CME STP supports the following clients:

Client Type


Client Type


Trading Firms

Allows Trading Firms to view Exchange trading, off-Exchange trading, and clearing activity using Subscription and Query requests and Trade Capture Report responses, associated with their Trading Firm only.

Asset Managers 

Allows Asset Managers to view all trades associated with the Trading Firms that are set up for them (via CME Account Management Service) using Subscription and Query requests and Trade Capture Report responses.


Allows Brokers to view ONLY CME ClearPort trades that they have brokered using Subscription and Query requests and Trade Capture Report responses.

Mode of Connectivity

Interaction with the API is session-less. Provide a username and password on each HTTP request, and CME STP authenticates it. CME STP sends a token in response to valid subscription requests and valid query requests where the response requires multiple pages. Continue the subscription or request the next page of the query by sending CME STP this token on subsequent requests. Both customers and CME STP will use the x-cme-token custom HTTP Request Header to transmit this token.


CME STP is built upon Representation State Transfer (REST) web service technology.  In this methodology, HTTP URLs and methods (such as GET, POST, etc.), parameters, and statuses are used to model the remote procedure call behavior. 

The API utilizes the industry standard FIXML format with custom CME extensions.
