FIXML

This page is a one-stop information center for CME's® new XML-based standards, user guides and other resources that will meet your FIXML development needs. This page will be updated as resources become available.

XML-based Standards and User Guides:

*CME recommends using an XML editing tool such as XMLSpy to view the schema files.

Other Resources:

  • FIXML Naming Conventions (PDF)
  • TREX to FIXML Trade Capture Report Mapping Table (PDF)
  • TREX to FIXML Trade Type Mapping Table (PDF)
  • Example of PCS via FIXML(PDF) - an annotated example of a file of PCS (Position Change Specification) data in FIXML format, showing how simple it is to create such a file and exactly how to identify the firm and product on each record
  • XmlLine.exe - utility program which takes a text file containing XML as input, and outputs a text file in which each XML tag is on a line by itself.  Useful for inspecting XML files using NotePad or other simple text editor.  Run it at the command line, and simple provide two arguments – the name of the input file, and the name of the output file.  Particularly useful for FIXML, where typically each message is produced as a single line, which can be hard to read using simple text editors because of the line length.
