Abstract: Real-time financial data from a number of independent data sources is displayed in separate frames within a single browser window. Each frame displays data from a different source, each source having its own symbology for representing the data. The web page which provides the browser display includes mapping algorithms for mapping between the symbology used by different sites. A user can change one symbol within one frame and the change is automatically propagated to all of the frames pre-selected by the user.

Abstract: Browsers which are required to display a large amount of constantly changing real-time information tend to make excessive demands on available computational resources, since the browser needs to update the screen every time a piece of information in its document object model changes and this process is inherently inefficient. By queuing real-time data updates and emptying the queue at periodic intervals, all updates received within those intervals are simultaneously written to the browser's document object model, so reducing the burden of updating the screen. In addition, earlier updates held in the queue can be overwritten by subsequent updates, so that out-of-date information is never provided to the browser.
