System for distributing, processing and displaying financial information
First Claim
1. In combination in system apparatus for disseminating and selectively processing and displaying financial information for a population of n investment securities, when n is a positive integer;
- said system apparatus comprising a hierarchal arrangement of variable content memory means disposed in a plurality of digital processing individual, branch, and area work stations, said hierarchal arrangement characterized by progressively completed variable content memory means;
each of said individual work stations including a display, a central processor, variable content memory means, memory means containing a program, and signal entry means;
said variable content memory means including plural storage elements for storing data characterizing a subpopulation k of the population n of investment securities where k<
n;
said signal entry means for requesting display of selected financial information stored in said variable content memory means;
trade information means for serially furnishing current trade information messages for the population of investment securities in parallel to said central processors of said work stations;
said program containing means for controlling said central processors;
said central processors of each of said work stations operatively selecting data received from said trade information means corresponding to said stored security sub-population and updating the data in said variable content memory means for said stored security sub-population.

Abstract
A data processing and communication system distributes and displays financial market ticker, quotation, news and ancillary information via a plurality of stored program controlled work stations. Stock trade executions, quotations and other ticker plant information is communicated in parallel to a hierarchy of system data processing terminals, e.g., those located at area, branch and individual work station locations. Storage media at the several system data processing levels extracts and stores data base information of differing purport and completeness for the disseminated data to support the system work station users.
In accordance with one aspect of the present invention, information characterizing a dynamically changing sub-population of the overall ensemble of market securities is maintained at and becomes immediately available to each work station responsive to the pattern of usage at that specific station. Various derivative tasks, such as security price limit alerts, are user programmable and are activated by the contents of the work station data base.
