This is the sixth in our series of briefings on MiFID and MiFIR. Below, we describe new obligations set out in MiFID that apply to investment firms engaging in algorithmic trading to have in place risk control measures, and authorisation requirements for third country firms providing services into or establishing a branch within the European Union as set out in MiFID and MiFIR.
