System and method for risk management
First Claim
1. A method for computing a margin requirement during the trading day in an electronic trading system, the method comprising:
- determining at a spread risk calculator a first margin requirement using a first base margin and a generic spread number, where the generic spread number is associated with working spread orders and filled positions, and wherein the generic spread number represents a number of spreads, wherein the generic spread number is found using the following relationship;
(total maximum leg position−
outrights)/2;
determining at the spread risk calculator a second margin requirement using a second base margin and a number of outrights, where the number of outrights is associated with working outright orders and filled positions;
computing at the spread risk calculator a total margin requirement using the first margin requirement and the second margin requirement;
determining at 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
sending the order to buy or sell the tradeable object to the exchange when the available margin balance is greater than the total margin requirement.

Abstract
A margin requirement is computed while trading. The margin requirement may be calculated while trading because the preferred system takes into account working orders to generate the margin requirement. The on the fly possibility allows the preferred system to provide pre-trade risk calculations, but can also be used to provide post-trade calculations. A generic spread number and the maximum number of outright positions are determined. Using the spread positions and the maximum number of outright positions, a spread margin and an outright margin are calculated, which when summed provide a total margin requirement. Limits based in part on the total margin requirement may be imposed on one or more traders.
