AI Summary of Article 31 Monitoring of compliance with the rules of the MTF or the OTF and with other legal obligations

Member States are mandated to ensure that investment firms and market operators managing Multilateral Trading Facilities (MTFs) or Organised Trading Facilities (OTFs) implement robust monitoring systems to ensure compliance with established rules. These arrangements should include oversight of orders, transactions, and potential misconduct, while also adhering to data quality standards as required by Regulation (EU) No 600/2014.

Furthermore, these entities must promptly report significant rule infringements or disorderly trading to their competent authority, which in turn communicates this information to ESMA and other Member States. They are also required to assist authorities investigating market abuse, thereby strengthening the integrity of financial markets.
