For the purposes of the market abuse regime, broadly, a type of behaviour employed in the course of dealing in financial markets that can reasonably be expected, and is therefore accepted, in a UK market or a market in an EEA state (for example, as a result of customs established over a lengthy period of time), although it may potentially constitute market abuse in another market.

The concept of accepted market practices (AMPs), including the criteria that the Financial Conduct Authority (FCA) must take into account and the process it must follow in order to establish an accepted market practice, is set out in Article 13 of the UK Market Abuse Regulation.

Note that, as set out on the Market Abuse Regulation page of its website, the FCA has not currently established any AMPs and there are no EU AMPs that apply to UK markets.
