A tobashi scheme is a financial fraud where a client's losses are hidden by an investment firm by shifting them between the portfolios of other (genuine or fake) clients.
 Any real client with portfolio losses can therefore have their accounts flattered by this process.
 This cycling cannot continue indefinitely and so the investment firm itself ends up picking up the cost.
 As it is ultimately expensive there must be a strong incentive for the investment firm to pursue this activity on behalf of their clients. Multilateral trading facility
A multilateral trading facility (MTF) is a European 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 operation of a MTF is considered an investment service.
 The concept was introduced within the Markets in Financial Instruments Directive (MiFID), 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.
