A multilateral trading facility (MTF) is a European Union regulatory term for a self-regulated financial trading venue. These are alternatives to the traditional stock exchanges where a market is made in securities, typically using electronic systems. The concept was introduced within the Markets in Financial Instruments Directive (MiFID),[1] a European Directive designed to harmonise retail investors protection and allow investment firms to provide services throughout the EU.
Article 4 (15) of MiFID describes MTF as multilateral system, operated by an investment firm or a market operator, which brings together multiple third-party buying and selling interests in financial instruments – in the system and in accordance with non-discretionary rules – in a way that results in a contract. The term 'non-discretionary rules' means that the investment firm operating an MTF has no discretion as to how interests may interact. Interests are brought together by forming a contract and the execution takes place under the system's rules or by means of the system's protocols or internal operating procedures.
The MTF can be operated by a market operator or an investment firm whereas the operation of a regulated market is not considered an investment service and is carried out exclusively by market operators that are authorised to do so. The United States equivalent is an alternative trading system.
