The European Commission has adopted a delegated regulation supplementing MiFIR. This Regulation aims at specifying, in particular, the rules relating to determining liquidity for equity instruments, the rules on the provision of market data on a reasonable commercial basis, the rules on publication, order execution and transparency obligations for systematic internalisers, and the rules on supervisory measures on product intervention by ESMA, EBA and national authorities, as well as on position management powers by ESMA.
