Abstract: Systems and methods for financial data analysis are provided. A system is provided wherein financial data associated with stocks and stock options is collected from multiple sources and calculations performed thereon to derive values for a set of searchable screening parameters related to searching stock option spreads. Users may access the system and provide values and ranges of values for searching the set of searchable screening parameters. In response, users are presented with the set of option spreads, in sorted order, that satisfy the user-supplied search values. Users may select to execute an option spread in which case the system automatically executes the plurality of option trades that underly the spread.

Abstract: A system for testing option search strategies comprises a repository of historical option data reflecting financial market conditions on a plurality of days in the past. The system is adapted to receive user defined search criteria for searching the repository of historical option data for option investments, search the repository of historical option data for option investments satisfying the user defined search criteria, and transmit the results. The system is further adapted to receive a request to use the user defined search criteria to search current financial market data for existing investment opportunities.

Abstract: Exemplary systems and methods for analyzing and searching financial instrument data respond to user defined searches using updated financial market data. Potential returns from different investment strategies can be viewed together so that the returns and risks can be compared and contrasted. The effect on various option strategies of a change in the price of the underlying stock can be analyzed. Potential investment opportunities relating to an existing investment position can be identified. Stock repair opportunities relating to a selected stock investment can be identified and implemented.

Abstract: A client establishes and/or modifies an interactive account on a server via proprietary sorting and filtering and reporting criteria as a means for timely processing of online financial data and/or other business information to retrieve valuations, sorted lists, etc. The method involves establishing a link with a server preset and programmable with client criteria for investment or decision making, acquiring data, sorting, filtering, etc.

Abstract: Methods and apparatus for extracting sample components from complex matrices using supercritical fluid as the principal extracting solvent are disclosed. The invention takes advantage of the fact that the solvent power of a supercritical fluid is stepwise settable by the parameters of density, modifier concentration, and temperature. Accordingly, methods and apparatus for extracting a component from a sample using fluid flow system having a variable and controllable flow restriction are disclosed. The methods of the present invention comprise the steps of inserting the sample into the sample container section, inputting temperature, pressure, flow rate and extraction time set points. Flow rate is controlled and system pressure regulated by the variable flow restriction. The output stream from the extraction is then expanded through a nozzle and into a trap. In certain embodiments, the trap is filled with chemically active packing material.
