Abstract: A method for performing financial trading amongst a plurality of alternative trading systems using a common financial computer platform. The method including the steps of receiving at the common financial computer platform a buy-order for a prescribed number shares at a prescribed price. Electronic communication is then established between the common financial computer platform and each of the plurality of alternative trading systems. At least a portion of the buy-order is then submitted from the common financial computer platform to each of the plurality of alternative trading systems. The common financial common platform then monitors each of the plurality of alternative trading systems to determine if at least a portion of the buy-order was executed by one of the plurality of alternative trading systems.

Abstract: The preferred embodiments provide improved systems, methods and products for the optimization of a portfolio and/or multi-portfolios of assets, such as stocks. In some preferred embodiments, new methodology can be employed wherein a confidence region for a mean-varience efficiency set is utilized. In some preferred embodiments, new methodology can be employed for improved computation of a reward-to-variability ratio or Sharpe Ratio. In some preferred embodiments, new methodology can be employed for multiportfolio optimization. In some preferred embodiments, a portfolio optimization engine or module can be adapted to implement one or more of these new methodologies, along with any other desired methodologies.

Abstract: A system for generating liquidity includes a plurality of client user interfaces and a matching system. Each client user interface includes a trading desktop which stores unexecuted trading positions. The matching system is coupled with the plurality of client user interfaces and configured to receive information about the unexecuted trading positions. The system can identify as a match one or more first indications of interest which can fulfill one or more second indications of interest, based upon the information about the unexecuted trading positions. For the identified matches, the system can provide a notification of the match and an invitation to execute the match to corresponding client user interfaces. When an invitation is accepted, the system forwards an order to an order execution system for execution.

Abstract: In a preferred embodiment, this invention includes software processes distributed on one or more computer systems that exchange messages in order to facilitate an intermediated exchange of financial commodities between a plurality of participants. The messages are exchanged according to a preferred protocol that leads to a satisfactory exchange that meets the objectives of the participants, and that substantially maximizes in a fair manner the total amount of financial commodities exchanged. Optionally, the invention employs heuristic rules in association with the preferred protocol that adapt the protocol to the time and exchange requirements of financial commodities. In other embodiments, this invention is equally applicable to the exchange of any tangible or intangible commodities. In a general embodiment, this invention further includes a preferred message-exchange protocol for the construction of computer programs representing exchange participants and an intermediary.

Abstract: A method and system for forecasting the transaction cost of a portfolio trade execution that may be applied to any given trade strategy or an optimal trade strategy that minimizes transaction costs. In preferred embodiments, a server comprises one or more computers that act as an automated forecaster whereby it accepts user-defined input variables from customers and generates a transaction cost estimation report based on those variables. The server is programmed with specific transaction cost estimation and optimization algorithms that model the transaction costs of a specific trade execution based on the user's trading profile and market variables.
