Scanning based spreads using a hedge ratio non-linear optimization model
First Claim
1. A computer implemented method of computing quantities of each of a plurality of derivative products to include in a portfolio, each of the plurality of derivative products being characterized by a product position based on underlying product and a product delta representative of a sensitivity of the product position to change in price of the underlying product, the portfolio being characterized by a portfolio delta representative of a net sum of the product delta of each of the plurality of derivative products included in the portfolio, the quantities being computed so as to optimize credit towards a margin requirement for the portfolio while maintaining the portfolio delta of the portfolio substantially close to zero, the computer including a processor, the method comprising:
- for at least one derivative product of the plurality of derivative products, identifying, by the processor, an exemplary set of first quantities of the at least one derivative product and for each first quantity of the at least one derivative product of the set of first quantities;
computing, by the processor, second quantities of each of the other of the plurality of derivative products such that the product delta of the second quantity of each of the other of the plurality of derivative products offsets the product delta associated with the first quantity of the at least one derivative product; and
for each spread combination of the first and second quantities of the at least one derivative product and the other of the plurality of products;
computing, by the processor, an implied margin for the spread combination;
computing, by the processor, an outright margin for the spread combination;
computing, by the processor, an implied credit rate for the spread combination based on both the implied margin and the outright margin for the spread combination;
computing, by the processor, a difference between the implied credit rate and a target credit rate for the spread combination;
generating, by the processor, a sum of each computed difference for each spread combination of the selected quantity of the at least one derivative product; and
wherein the method further includes;
identifying, by the processor, a target quantity, of the at least one derivative product of the set of quantities, having the lowest summed computed difference, the target quantity of the at least one derivative product, in conjunction with quantities of the other of the plurality of derivative products computed to offset the product delta associated with the target quantity of the at least one derivative product, representing a portfolio having maximum credit towards a margin requirement for the portfolio while maintaining the portfolio delta of the portfolio at or within a difference of zero.

Abstract
The disclosed embodiments utilize hedge ratios to determine the optimal hedge ratio and associated scanning spread. This tells traders what ratios of the quantities of products they should have in their portfolio in order to maintain the status of the portfolios as delta neutral, i.e. be delta hedged, and receive optimal margin credits therefore.
