Abstract:
1. A non-transitory computer readable medium having stored therein instructions executable by a processor, wherein the instructions are executable to: determine by a spread risk calculator a first margin requirement using a first base margin and a generic spread number, where the genetic spread number is associated with working spread orders and filled positions, and wherein the generic spread number represents a number of spreads, wherein the genetic spread number is found using the following relationship: (total maximum leg position−outrights)/2; determine by the spread risk calculator a second margin requirement using a second base margin and a number of outfights, where the number of outrights is associated with working outright orders and filled positions; compute by the spread risk calculator a total margin requirement using the first margin requirement and the second margin requirement; determine by a limit module whether to send an order to buy or sell a tradeable object to an electronic exchange based on the total margin requirement and an available margin requirement; and send the order to buy or sell the tradeable object to the exchange when the available margin balance is greater than the total margin requirement.
