(2)The provisions in this Regulation are closely linked, since they deal with a set of related obligations for investment firms engaged in algorithmic trading pursuing market making strategies and for trading venues where those market making strategies may take place. To ensure coherence between those provisions, which should enter into force at the same time, and to facilitate a comprehensive view of and a compact access to them by persons subject to those obligations, including investors that are non-Union residents, it is desirable to include those provisions in a single Regulation.
