An order (buy or sell order) that is executed by a commodity pool operator or an advisory firm on behalf of a large number of clients. This is usually done by entering a sizable order that aggregates the amounts ordered by individual clients and then allocating the contracts to respective client accounts. For example, if an advisory firm expects the stock market would perform better over the course of next quarter, it may select to position a number of clients in a specific index futures. It would purchase 300 futures contracts for this specific group of clients and will assign to each client a number of the future contracts.
