Article 18 10.

Member States shall require that investment firms and market operators operating an MTF or an OTF provide the competent authority with a detailed description of the functioning of the MTF or OTF, including, without prejudice to Article 20(1), (4) and (5), any links to or participation by a regulated market, an MTF, an OTF or a systematic internaliser owned by the same investment firm or market operator, and a list of their members, participants and/or users. Competent authorities shall make that information available to ESMA on request. Every authorisation to an investment firm or market operator as an MTF and an OTF shall be notified to ESMA. ESMA shall establish a list of all MTFs and OTFs in the Union. The list shall contain information on the services an MTF or an OTF provides and entail the unique code identifying the MTF and the OTF for use in reports in accordance with Articles 6, 10 and 26 of Regulation (EU) No 600/2014. It shall be updated on a regular basis. ESMA shall publish and keep up-to-date that list on its website.
