Claim One:
1. A computer implemented method for repeated buying and selling a security through a brokerage computer system, the method comprising: through a client computer system in communication with the brokerage computer system, providing for selecting a buy decision model and a sell decision model for buying and selling the security, wherein the buy decision model comprises a mathematical equation for receiving data and providing at least one value, wherein the at least one value is compared to a decision point for deciding at least in part whether to buy the security, wherein the decision point comprises at least one of a single value and a range of values; selecting a buy decision model and a sell decision model; computer implemented inputting data into the buy decision model, wherein the data comprises real time data for the security; computer implemented resolving the mathematical equation of the buy decision model and comparing the at least one value to the decision point; when the buy decision model indicates a decision to buy the security then automatically generating a buy transaction order for the security, otherwise repeating the above steps beginning with the step of computer implemented inputting data into the buy decision model, wherein the decision to buy the security is based at least in part on the result of comparing the at least one value to the decision point; automatically transmitting the buy transaction order to a market computer system; computer implemented inputting data into the sell decision model wherein the data comprises real time data for the security; when the sell decision model indicates a decision to sell the security then automatically generating a sell transaction order for the security, otherwise repeating the above steps beginning with the step of computer implemented inputting data into the sell decision model; automatically transmitting the sell transaction order to the market computer; and repeating the above steps beginning with the step of computer implemented inputting data into the buy decision model.
