Recital 66

In addition to measures relating to algorithmic and high-frequency algorithmic trading techniques it is appropriate to ban the provision of direct electronic access to markets by investment firms for their clients where such access is not subject to proper systems and controls. Irrespective of the form of the direct electronic access provided, firms providing such access should assess and review the suitability of clients using that service and ensure that risk controls are imposed on the use of the service and that those firms retain responsibility for trading submitted by their clients through the use of their systems or using their trading codes. It is appropriate that detailed organisational requirements regarding those new forms of trading should be prescribed in more detail in regulatory technical standards. This should ensure that requirements can be amended where necessary to deal with further innovation and developments in that area.
