30/03/2026G

The requirement in MAR 5.3.1AR(4) does not prevent a firm, with the appropriate permission, from executing orders against its proprietary capital outside the MTF it operates.

30/03/2026G

A firm with the appropriate permission may engage in matched principal trading for the purpose of executing client orders on or outside an MTF it operates. An appropriate permission comprises the permitted activity of dealing in investments as principal. When a firm engages in matched principal trading by executing an order on an MTF it operates, it does so by dealing on own account and is subject to the Handbook requirements relating to this activity and the investment service of execution of orders on behalf of clients, as applicable.

Operation of a primary market in financial instruments not admitted to trading on a regulated market

19/01/2026G

The FCA will be minded to impose a variation on thePart 4A permission of an MTF operator that operates a primary market in financial instruments not admitted to trading on a regulated market in order to ensure its fulfilment of the requirements in MAR 5.3.1R as regards fair and orderly trading.

19/01/2026G

Rules regarding operating a primary MTF can be found in MAR 5-A (Multilateral trading facilities operating as a primary MTF).

19/01/2026G

Rules regarding protected forward-looking statements in an MTF admission prospectus for use on a primary MTF can be found in PRM 8 (Protected forward-looking statements).

Transferable securities traded without issuer consent

03/01/2018R

Where a transferable security, which has been admitted to trading on a regulated market, is also traded on an MTF without the consent of the issuer, the firm operating the MTF must not make the issuer subject to any obligation relating to initial, ongoing or ad hoc financial disclosure with regard to that MTF.
