Deutsche Börse Readiness Newsflash | MiFID II/MiFIR order flagging requirements: Final reminder of Algo ID solution and CUE pre-validation tool - Changed requirements with T7 Release 15.0

As announced with Deutsche Börse Circular 027/26 from 16 June 2026, we kindly remind you of the changes to the Algo ID solution, the Common Upload Engine (CUE) validations for Short Code ID and Algo ID uploads, and an enhancement of the Short Code ID and Algo ID error reports, which will be introduced with T7 Release 15.0 on 9 November 2026.

Production start: 9 November 2026

Please be reminded that Trading Participants are required to familiarize themselves with the new requirements for the Algo ID solution, including the submission of information on substantial updates to their trading algorithms and the annual submission of test documentation explaining the means of testing. This information is also required for new trading algorithms. 

In addition, the CUE pre-validation tool for Short Code ID and Algo ID upload files will be decommissioned, and upload validations will be limited to checks of file type, file structure, and naming convention. For intraday uploads, comprehensive validation results of the file content are provided to Trading Participants via intraday reports TR160 - TR163 at 10:00 CET, 14:00 CET, and 18:00 CET, in addition to the end-of-day reports.

Furthermore, the existing field “processingTime” in Short Code ID and Algo ID reports TR160, TR162, TR169 will be enhanced for error 1 “ShortCodeID registration / AlgoID registration is missing”. The timestamp of the Short Code ID or Algo ID missing identification will be added. Therefore, the format of the field changes and Trading Participants shall adhere to the new field format.
