Abstract: The present invention is a system that provides the user with an downloadable, browser based interface that allows the user, based on his own preferences, to place fungible goods, such as stocks, in a basket as a list and trade all of the goods in the basket as a unit. The interface allows the user to execute trades in/of the basket in a single user action (i.e. one mouse click). A list region is provided where the goods are listed and an execute control initiates trading of the goods in the basket. The user can also specify an amount to be invested, goods weights, a measurement index and how the trades are to be limited. The interface presents, allows changes in (open, close, balance, etc.), summarizes and records the goods transactions as/within the unit basket.

Abstract: The present invention is a tracking system that includes an order tracking database that stores the status of orders as they are processed within a distributed order fulfillment system that has a number of order execution systems that fill all or part of each order. Each order goes through a number of different transaction stages and the result of each stage is reported as an event to the database. The events are transmitted as messages using an output queue in the order execution system and an event message queue in an event tracking service. The tracking service updates the database when events appear in the event queue. The message processing system operates independently of order processing allowing order processing to continue while the tracking service updates the database. The messages include the components of an asset record of a core system database. The status of any order within the distributed system can be obtained from the database.
