Abstract: An information system for enabling a buyer subscriber and a seller subscriber to directly communicate, negotiate and order financial instruments, particularly fixed income instruments, without the need for an intermediary or inter-dealer broker. The information system is adapted to publish real-time bond offerings, provide search capabilities to allow users to locate bond offerings meeting specific criteria, send real-time notification of offerings entering the marketplace in which a user has a registered interest, manage and negotiate order privileges, provide a network for real-time communication between counter-parties in a transaction, and allow direct communication between a fully disclosed buyer subscriber and a fully disclosed seller subscriber. Also, the information system can cooperate or be integrated with existing industry systems, such as inventory management systems to import offering information, and back-office systems to export transaction information.
