MiFIR Transaction Reporting File Specifications

  • Only the following MiFIR Fields will be available in the reports. Client systems must join this information with in-house records to generate the full report.
  • Please note that the MiFIR Data Service does not take into account any of Client's own circumstances that could affect the required contents of its Transaction Reports. Clients are solely responsible for complying with the Reporting Obligation and must use data provided by the MiFIR Data Service accordingly. 
  • Use this guide to map from the CSV to individual fill messages (Note: when reporting the Trading Venue Transaction ID Code, do not include the pipe delimiters within this field on the CSV).
  • Field 41- Instrument Identification Code - CME Group products do not have an ISIN, and are not required to have one under CFTC rules. MiFID fields 42-56 will instead be provided to help clients identify the traded instruments, with the exception of field 47 – Underlying instrument code since this ISIN is not stored within CME systems.
