Abstract:
1. A method including: determining by a computing device a total maximum leg position based on maximum leg positions for each of one or more tradable objects, wherein the maximum leg positions represent a maximum position in each leg; determining by the computing device a number of total outright positions based on a total filled net long position and a total filled net short position, wherein the number of total outright positions represents the number of positions that are not considered part of a spread; determining by the computing device a number of spreads based on (the total maximum leg position−the number of total outright positions)/2, wherein the number of spreads represents a generic spread position; determining by the computing device a first margin requirement based on the number of spreads and a first base margin value; determining by the computing device a maximum number of outrights based on a number of outrights due to working buy outright orders and a number of outrights due to working sell outright orders, wherein the maximum number of outrights represents the maximum number of outright positions possible with a current configuration of outright market working orders and filled positions; determining by the computing device a second margin requirement based on the maximum number of outrights and a second base margin value; determining by the computing device a total margin requirement based on the first margin requirement and the second margin requirement; and providing by the computing device the total margin requirement, wherein a decision to allow an order to be sent is based on an available margin balance and the total margin requirement.
