Article 54 Monitoring of compliance with the rules of the regulated market and with other legal obligations
1. Member States shall require that regulated markets establish and maintain effective arrangements and procedures including the necessary resource for the regular monitoring of the compliance by their members or participants with their rules. Regulated markets shall monitor orders sent including cancellations and the transactions undertaken by their members or participants under their systems in order to identify infringements of those rules, disorderly trading conditions or conduct that may indicate behaviour that is prohibited under Regulation (EU) No 596/2014 or system disruptions in relation to a financial instrument.
2. Member States shall require the market operators of the regulated markets to immediately inform their competent authorities of significant infringements of their rules or disorderly trading conditions or conduct that may indicate behaviour that is prohibited under Regulation (EU) No 596/2014 or system disruptions in relation to a financial instrument.
The competent authorities of the regulated markets shall communicate to ESMA and to the competent authorities of the other Member States the information referred to in the first subparagraph.
