The Global Technical Committee has reviewed and preliminarily approved the Gap Analysis. This proposal seeks to add a number of codes (a.k.a. enumerated values) to existing code sets of the FIX specification based on communication from member firms and issues raised in the FIX discussion forum, e.g. in FIX Standard Errors and Omissions 2018-2021. The changes in this proposal are not considered to be errors but rather extensions identified by the GTC based on member feedback and internal analysis.

The Global Technical Committee has reviewed and preliminarily approved the Gap Analysis. It contains a large number of errors and omissions discovered in the FIX Standard, e.g. misspellings or gaffes in the description. The various changes are not necessarily linked to one another. Most of them were collected over time in the discussion forum (see FIX Standard Errors and Omissions 2018-2021) or collected via emails from members. A new thread FIX Standard Errors and Omissions 2022 has been created for errors and omissions detected by the FIX Trading Community going forward.

The Global Technical Committee has reviewed and preliminarily approved the Gap Analysis. It extends the values of BeginString(8) for FIX Latest to include the session profile identifiers for the FIX Session Layers of FIX 4.2 and FIX 4.4. Currently, FIX Latest requires BeginString(8)=”FIXT.1.1”, i.e. to reference FIX Transport, the FIX Session Layer introduced with FIX 5.0. With this extension, you no longer need to change your session layer, i.e. you can continue to use BeginString(8)=”FIX.4.2” or BeginString(8)=”FIX.4.4” together with the latest extensions made to the FIX Protocol.

The document now enters a public comment period in which public review and feedback is encouraged. Once the public comment period closes, the GTC will review public comments before final approval by the GTC Governance Board.

Cboe is developing an option trade compression service called Cboe Compression Service.  The service will allow for bilateral and multilateral compression. This information is then passed to The Options Clearing Corporation (OCC) and the clearing firms.

This Gap Analysis document establishes the technical requirements for bilateral and multilateral compression for portfolio and netted trades using the FIX Protocol.

The document is now out for public comment for a two week period commencing 26th July 2021 and ending 8th August 2021.
