Templates (0)
The library lists no templates for this return.
EU return: the XML schema and field definitions are published by ESMA under RTS 22 (Commission Delegated Regulation (EU) 2017/590). No library ESMA entry exists yet; described here from the CNB's own pages. The CNB's own report codes implementing it in SDAT are TRAFIM10 (transactions), TRAFIM20 (orders), TRAFIM30 (order instructions) and REFFIM10/11 (reference data). Source
Validation rules
The CNB 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 XML schema (RTS 22) plus field-level guidelines.
ESMA's FIRDS reference-data registers are also used as external code lists in the checks.
How they were counted
Not counted here: ESMA publishes the XML schema and guidelines for MiFIR transaction reporting directly.
Counts are in the CNB's own unit, so they are not comparable with other regulators' counts.
Public data
No published data from this return was found. No data from this return published by the Czech National Bank was found on the pages checked. Source
