Article 69
Aggregation and allocation of transactions for own account
1.
Investment firms which have aggregated transactions for own account with one or more client orders shall not allocate the related trades in a way that is detrimental to a client.
2.
Where an investment firm aggregates a client order with a transaction for own account and the aggregated order is partially executed, it shall allocate the related trades to the client in priority to the firm.
Where an investment firm is able to demonstrate on reasonable grounds that without the combination it would not have been able to carry out the order on such advantageous terms, or at all, it may allocate the transaction for own account proportionally, in accordance with its order allocation policy referred to in Article 68(1)(c).
3.
As part of the order allocation policy referred to in Article 68(1)(c), investment firms shall put in place procedures designed to prevent the reallocation, in a way that is detrimental to the client, of transactions for own account which are executed in combination with client orders.
