MIR 3.6.4

If a Recognised Investment Exchange decides to provide investment firms and credit institutions details of transactions in Financial Instruments, it must do so on reasonable commercial terms and on a non-discriminatory basis. This requirement may be waived or deferred in respect of large volume or for certain types of trades, as specified by the Regulator, in which case the Recognised Investment Exchange must ensure that the existence of and the terms of the deferral are disclosed to users and Members of their facilities and to investors.
