   unless permitted in MAR 5A.3.5R, not execute any client orders against its proprietary capital or the proprietary capital of any entity that is part of the same group or legal person as the firm; and

3. (3)

   ensure that the operation of an OTF and of a systematic internaliser does not take place within the same legal entity, and that the OTF does not connect with another OTF or with a systematic internaliser in a way which enables orders in the different OTFs or systematic internaliser to interact.
