      This is now the active version, but prior versions are not expected to produce errors with the new optional attributes.
  • As was introduced in earlier versions, users will be able to use this build to test chunked RPFs (multiple RPF packages for a single date and cycle) when they become available.
  • This build improves performance of loading risk data during margin calculations. Users are encouraged to perform performance tests of this version and provide feedback. 

Changes to Technical Configurations 

  • This build requires Windows users to support Visual C++ Redistributable for Visual Studio 2015-2022.

Notes

  • This is an optional production build. Users are recommended, but not required, to deploy this build in the Production environment at the earliest convenience. This version can be deployed prior to the equities in SPAN 2 framework production go live date.

  • CME has made the following sets of risk parameter files (RPF) available for user testing.

    • Perform functional testing with any production risk parameter data file (RPF) from July 1, 2024 onward.

      • Risk parameter file location: [user local site]/pub/SPAN2/rpf/
      • Production risk parameter file name: cme.span2.yyyymmdd.[cycle code].zip
    • Perform functional and impact analysis testing with test versions of the RPF data containing equities in the SPAN 2 framework from selected dates in August, then August 23, 2024 onward.

Version: v3.1.10

...

Updates

Description

Enhancements and Fixes

  • This build introduces a simulation for multi currency support for contracts in an existing Pod allowing users to functionally test a multi-currency margin result for a set of mocked test contracts. A subsequent production ready build is expected to be released in Q2 2024.
    • Contracts for testing in this build:
      • ES, DVE, FT1 and N1 futures (options excluded)
      • Please see See also the sample portfolio (csv format) and risk results message (json format) published in theCME CORE download centerDownload Center.
    • The equity products in-scope for testing are margined via SPAN 2 framework and will be displayed under the Pod "NATGAS" and the Product group "Henry Hub Natural Gas."
    • The "requirement amounts" section at the Pod and Product Group levels produces aggregated margin results in US dollars.
    • The "currency amounts" section at the Pod level produces a margin breakdown in local currency.
      • Users testing this build are expected to validate they can pass the "currency amounts" into their downstream processes to ensure their integration allows for multiple currencies in the same Pod.

Changes to Technical Configurations 

  • This build requires Windows users to support Visual C++ Redistributable for Visual Studio 2015-2022

Notes

  • This release should not be deployed to production and it will only support risk parameter file(s) as a means of validating existing interface implementation. A subsequent production ready build is expected to be released in Q2 2024.
  • This build should be tested using a sample risk parameter file (RPF) which is available over secure FTP at the following site: /pub/SPAN2/rpf/test. The file has the naming convention prefix "Test" but otherwise matches standard naming convention.
  • Schema changes are out of scope for this build.

Known Issues

  • None.
