Templates (0)

The library lists no templates for this return.

EU return: the fields, XML schemas and validation rules are ESMA's (ESMA Guidelines on transaction reporting, order record keeping and clock synchronisation under MiFID II). No library ESMA entry exists yet to link. ESMA's own site was not requested; see gaps. Source

Validation rules

The FIN-FSA publishes the checks it runs on this return. They could not be counted from the published material. Software can run them exactly as published. Source

How they are written: ESMA data validation rules for MiFIR transaction data, and XML schemas.

FIN-FSA processes files continuously and returns feedback messages overnight; a test service mirrors the production service for pre-live testing.

How they were counted

Not counted: ESMA's MiFIR transaction-reporting validation rules apply.

Counts are in the FIN-FSA's own unit, so they are not comparable with other regulators' counts.
