Abstract: A method of allocating a quantity of an incoming order to a plurality of standing orders, wherein the plurality of standing orders are contra to the incoming order and have an identical price is disclosed. The method includes allocating a first portion of the quantity of the incoming order to a first subset of the plurality of standing orders, wherein each order comprising the first subset is designated with a priority; allocating a second portion of the quantity of the incoming order to a second subset of the plurality of standing orders, wherein each order comprising the second subset was submitted by a preferred trader; allocating a third portion of the quantity of the incoming order to a third subset of the plurality of standing orders in accordance with when each order comprising the third subset was received; and allocating a fourth portion of the quantity of the incoming order to a fourth subset of the plurality of standing order proportionally.

Abstract: A method of allocating a quantity of an incoming order for a product develops a value that indicates a portion of the incoming order this is to be allocated using a FIFO algorithm and allocates a first portion of the incoming order to standing orders using the FIFO algorithm. The method further allocates a second portion of the incoming order to standing orders using a pro-rata algorithm, wherein the step of allocating the second portion leaves a remaining quantity of the incoming order. In addition, the method allocates the remaining portion to the standing orders using a FIFO algorithm.
