Filed:

Oct 1, 2003

Appl. No.:

10/676318

Inventors:

James W. Farrell - Carol Stream IL, US
David Salvadori - Bartlett IL, US
Arjuna Ariathurai - Chicago IL, US
John Falck - Chicago IL, US
Scott Johnston - Oak Park IL, US
Agnes Shanthi Thiruthuvadoss - Chicago IL, US

Assignee:

Chicago Mercantile Exchange, Inc. - Chicago IL

International Classification:

G06Q 40/00

US Classification:

705 36R, 705 35, 705 37

Abstract:

Systems and methods are provided for processing derivative product orders at an exchange. Traders provide derivative product order risk data to the exchange. The order risk data may include maximum delta, gamma and/or vega utilization values for derivative product contracts based on the same underlying product. Before executing a trade, a match system analyzes the trader's current utilization state and the utilization that would result after the trade. The match system may then execute all or a portion of the trade.

Appl. No.:

11/556499

International Classification:

G06Q 40/00

US Classification:

705 36R, 705 35

Abstract:

Methods and systems for an exchange to handle variable derivative product order prices are disclosed. The price of a derivative product order (bid or offer) is updated based on changes in the price of a related underlying product. Price determination variable(s), such as delta and gamma, are used to determine the price of the order. The exchange may periodically recalculate the price without requiring the trader to transmit additional information to the exchange.

International Classification:

F02M 59/00

US Classification:

2395332, 239 88

Abstract:

A method of manufacturing a fuel injector having high-flow orifices in its tip includes removing a bulb from a fuel injector tip having at least one spray orifice with a first diameter, and friction welding a slug to the fuel injector tip, including forming a fused interface of material of the slug and material of the fuel injector tip. The method further includes modifying the slug subsequent to friction welding the slug to the fuel injector tip, including forming a new bulb from the slug having at least one spray orifice therein with a different diameter than that of the removed bulb. A remanufactured fuel injector, and fuel injector tip, includes an injector tip body having a first tip portion of a first material and a second tip portion of a material compatible for friction welding with the first material. The injector tip body further includes a third tip portion attaching the first tip portion to the second tip portion, the third tip portion including a friction weld formed during remanufacturing of the fuel injector tip.

International Classification:

G06Q 40/00

US Classification:

705 37, 705 35, 705 36 R

Abstract:

Systems and methods are provided for executing a hedge transaction in connection with the execution of a derivative product order in which the price of the derivative product is defined by one or more variables. The hedge transaction may be executed at an exchange or match engine that is different from the exchange or match engine executing the derivative product order. The execution of derivative product transaction may be contingent on the existence of an appropriate hedge transaction. Alternatively, a best efforts approach may be used to fill the hedge transaction order after executing the derivative product transaction.
