Validation rules

The Finanstilsynet publishes the checks it runs on this return. They could not be counted from the published material. They are written for people to read; software cannot run them as published. Source

How they are written: ESMA MiFIR data reporting Q&A and guidelines on transaction reporting.

How they were counted

Not counted here: ESMA's MiFID II/MiFIR transaction reporting guidelines and Q&As apply.

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