Patent ID: 7266520

Claim:
A method for using a digital electrical machine to electrically process signals in generating output, the method including the steps of: providing a first digital electrical computer apparatus including a digital computer having a processor, the processor electrically connected to a memory device for storing and retrieving machine-readable signals, to an input device for receiving input data and converting the input data into input electrical data, and to an output device for converting output electrical data from the processor into output having a visual presentation, the processor being programmed to control the apparatus to receive the input data and to produce the output data: respectively entering financial characteristics sufficient for computing a price for preferred-return instruments representing investments; respectively entering amounts that buyers want to buy of a member from a first group, the first group consisting of at least one of the instruments and at least one group of the instruments, at the respective buyer's hypothetical current preferred return; respectively entering amounts that sellers want to sell of a member of a second group, the second group consisting of at least one of the instruments and at least one group of the instruments, at the respective seller's hypothetical current preferred return; computing a demand schedule for each of said instruments corresponding to the first group; computing a supply schedule for each of said instruments corresponding to the second group; comparing the schedules to produce a current preferred return for each of the corresponding instruments in both the first group and the second group; computing a price for each said instrument having a current preferred return; and generating the output including respective amounts of the instruments respectively in association with at least one member of a group consisting of the current preferred return and the price.
