Patent ID: 7584144

Claim:
A method for electronic trading of goods, the method comprising: generating a first axis for a first good according to first market data via a computing device, the first market data received at the computing device from an electronic exchange for the first good; generating a second axis for a second good according to second market data via the computing device, the second market data received at the computing device from an electronic exchange for the second good; displaying a first axis associated with a first good via a visual output device associated with the computing device, the first axis having a plurality of value levels each associated with a value for the first good; displaying a second axis associated with a second good via the visual output device, the second axis having a plurality of value levels each associated with a value for the first good, the second good having a value relationship with the first good; generating at least a first indicator for a first good according to first market data via a computing device, the first indicator representing at least a quantity of an open order of the first good according to the first market data; dynamically displaying the at least a first indicator via the visual output device relative to one of the plurality of value levels of a first axis; generating at least a second indicator for a second good according to second market data via a computing device, the second indicator representing at least a quantity of an open order of the second good according to the second market data; dynamically displaying at least a second indicator via the visual output device relative to one of the plurality of value levels of a second axis, the second indicator representing at least a quantity of an open order of the second good; generating a common value axis relative to the first axis and the second axis via the computing device, the common value axis having a plurality of common value levels each aligned with a respective value level of the first axis and the second axis and representing a common value of the first and second goods; displaying the common value axis relative to the first axis and the second axis via the visual output device; receiving a user-initiated command via an input device of the computing device, the user-initiated command selecting a value of an order for any one of the first good and the second good according to a user-selected location of any one of the first axis and the second axis; and in response to the user-initiated command, generating and submitting the order on behalf of a user via the computing device.
