  • Patent number: 7451110
    Abstract: A system, method and computer program product for providing a trading exchange are disclosed. A request for conducting trade of a security is received from a user. The security associated with requested trade is evaluated to generate a derivative security. A trade is then executed for the user using the derivative security. Information relating to the executed trade is captured utilizing a network so that the captured information can be utilized to adjust an account of the user in accordance with the executed trade.

  • Publication number: 20070288695
    Abstract: An apparatus, system, and method are provided for sharing a cached security profile in a database environment. The apparatus, system, and method include a cache module for caching a security profile accessible to primary tasks and secondary tasks. An identification module is provided that distinguishes between primary tasks authorized to refresh the security profile and secondary tasks. A refresh module cooperates with the cache module and identification module to selectively refresh the security profile in response to a refresh request and expiration of the security profile such that an old version of the security profile is retained for use by secondary tasks until an execution window closes.
