How Does a Regulator or ARM Ascertain MiFIR Reportability?
The current application of MiFIR requires both the regulators and ARMs to filter through vast quantities of data to determine which transactions should be reported. Trading venues and systematic internalisers (SIs) are obliged to submit reference data for financial instruments to ESMA to be published in FIRDs. This is outlined in Article 27 of MiFIR and Article 4 of Market Abuse Regulation (MAR).
