12A.5 Holding trades for different customers in a Position Account and warehousing of trades
A Position Account in the name of the Trading Member may be used to hold positions of trades for different customers, provided that the Trading Member has procedures to ensure fair allocation to the customers.
If a customer's order is unlikely to be completed during a Market Day, the Trading Member may warehouse the customer's trades until the order is completed. The Trading Member must ensure that no customer's trade is warehoused for more than one Market Day, unless under exceptional circumstances. In such cases, the Trading Member must document the reasons for the extension of time.
