Description

The present invention relates to a data communication processing system, and more particularly to a system for collecting / processing / displaying financial market data, news and the like.

OBJECT OF THE INVENTION It is an object of the present invention to provide an improved user-friendly device for communicating, storing, processing and displaying financial market information, news and other original data and derived data.

In particular, it is an object of the present invention to provide an apparatus and method for communicating / displaying information useful for securities brokers, investors, and other people who are interested in financial markets. It is also intended to provide a multi-window that allows the user to perform linked control at a workstation under the jurisdiction of the system's microprocessor by displaying the display content and other market information of the sporadic and / or related market indicators. .

Another object of the invention is to provide immediate local access to a dynamically changing subgroup of securities of particular interest from a subscriber's workstation controlled by a storage program in a financial market telecommunications and display system. The purpose is to store securities data hierarchically in various system equipment.

[Structure of the Invention] The above-described object of the present invention is to collect, process, and display the display contents, quotes, news, and related information in a quote market in a financial market via a plurality of workstations controlled by a storage program. Is realized in the system specifically shown and described in FIG. For example, the stock transaction execution information, market price information, and other market price display information are sent in parallel to a hierarchical structure consisting of system data processing terminals such as area computers, branch computers, and personally owned workstations. Storage media at various system data processing levels retrieve and store database information about aggregated data for various purposes and completeness to assist users of system workstations.

According to another aspect of the invention, the information characteristic of a dynamically changing sub-group of market securities is maintained and instantly obtained at each workstation depending on the user's usage pattern at that particular station. It can be so. Various derivative tasks, such as stock price limit alerts and the display of customized selective quotes, are user programmable and are driven by the workstation's database.

Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings.

Referring to FIGS. 1A and 1B (hereinafter, referred to as FIG. 1 as a whole), it communicates information characteristic of the financial market generated at a central common position, and is in charge of clients of the securities brokerage industry. This information is made available to the workstations 110 _{i, j, k} of a potentially large number of subscribers whose business and / or business interests or interests are, for example, on the desks of people in the financial community. Improved communication for
The data processing device is shown in a block diagram. Looking at this system as a whole, each workstation 110
_{The i, j, k} includes a display device 107 such as a CRT controlled by the central processing unit 103. Also, workstation 110
_{i, j, and k} are storage devices 109 that store programs such as read-only memory (ROM) and random access memory (R
AM) etc., and a variable content storage device 111. The user's workstation RAM 111 stores a substantial amount of data that is of most interest to a particular workstation 110 user. Generally, the stored contents of the RAM 111 are different depending on the user. The RAM 111 may also store the program or a part of the program.

Each workstation 110 _{i, j, k} accesses the information stored in the computer above it in the computer hierarchy according to the present invention. Thus, for example, a securities broker (and all those in a similar position) at the illustrated workstation 110 _{i, j, k} may have a middle-tier branch computer 9 above its own workstation.
0 _{j, k} , in particular _, variable content RAM storage devices 95 and 96 that store more information than can be stored in RAM 111 of workstation 110 _{i, j, k} . Moving further up the computer hierarchy, workstations 110 _{i, j, k} access the contents of RAM 60 of computer 50 _k , which covers the area to which the branch computer is connected. Further, the entire system workstation 110 can access the master memory 12 of the customer database in the mainframe computer of the head office.

The basic data that characterizes securities transactions are generated by methods well known to those skilled in the art. In particular, trade information (execution price, turnover, quotes, etc.) is available on the New York Stock Exchange 28.
Is supplied to the market price display 35 from. Further, the market price indicator 35 is supplied with a large amount of transaction information from so-called local exchanges 30 ₁ to 30 _n . In addition, it may include domestic and international information. The output of the market price indicator is the information that is characteristic of the stock exchange execution on each exchange, the sell quote information, and the buy quote information. The output of the well-known market price display 35 that can be used at this stage is a common history content that is generally sent to a brokerage shop and other financial institutions via a ground communication line.

In accordance with the present invention, the market indicator output is provided to a receive-only earth station in an area computer or branch computer 50, 90 via a satellite dispersion microwave uplink 38. In order to make the transmission contents redundant, the information on the market display is radiated in a state of being multiplexed with the program for the television. Such data multiplexing with a television signal is known per se, for example modulating a video carrier in a vertical blanking interval which cannot be demodulated by a known television receiver tuned to the original television program to be multiplexed. Included as digital information. The receiving device 70 in the area computer or branch computer 50, 90 receives the swept portion of the output of the market price indicator 35.

The receiving device 70 has antennas 80 and 81 to facilitate continuous reception of market information. These antennas 80 and 81 respectively receive the radiation signal from the satellite and the radiation signal from the television. Looking at the receiver shown in Figure 1 for an area computer 50 _k , satellite signals and VHF or U
The HF television multiplexed signals are received by antennas 80 or 81, respectively, and detected by radio frequency (RF) receivers 78 ₁ and 78 ₂ . An alternative to the antenna such as a cable television system may be used. The demultiplexer 77 selects the baseband data stream output of one of the radio receivers / detectors 78 ₁ and 78 ₂ under the control of the central processing unit 72 based on an appropriate algorithm stored in the ROM storage device 74. Therefore, for example, the CPU can receive the data stream outputs of both receivers 78 ₁ and 78 ₂ and temporarily store them in the RAM 76, and select the one having the smaller error rate. Other selection algorithms are readily apparent to one of ordinary skill in the art.

In this way, securities trading information is directly supplied in parallel to each of the system branch computer and the area computers 90 and 50 by using radiation. In unit 50 _k each area computer 50, such as shown in Figure 1A for example, the received transaction information is stored under the control of a program stored in the read only memory 57 by the main central processing unit 56. In the upper area computer 50 _k in the computer 50-90-100 hierarchy shown in FIG. 2, RAM 60 holds substantially complete market data for the entire monitored security population. Of course, the functions of elements 72, 74, 76 are performed directly by elements 56, 57, 60.

Similarly, in a branch computer 90, such as a computer 90 _{j, k} , the variable content RAM storage device 96 does not store all monitored securities, but instead of all securities populations corresponding to securities of interest to the general public. Store information only for subpopulations. Computer 90 _{j, k} of the storage device 96, but fewer than the amount information held in the area computer 50 _k, the computer 90 _j, workstations connected 110 _i to _k, held _j, the RAM111 of _k Holds current market information for a substantially larger amount of securities population than is present.

Workstation as a system principle as a whole
110 When _{i, j, k} retrieves current price information about a security that is not currently stored in its storage device 111, the branch computer 90 connected to its workstation
Search the required information with _{j, k} . If you don't have the information you need at the branch level, branch computer 90
_{j, k} queries the area computer 50 _k via connecting modems 91, 52 and communication link 83. As such, various system hierarchy levels utilize affordable amounts of storage and computer power to meet the demand at each level.
The workstation 110 can obtain any information from its own internal storage device, branch, or area. If necessary, communication device 22 (switched telephone network, etc.)
Further information can also be obtained from the main office central processing unit 14 and the database 12 (source level 10) via the modem 25 or from the external database 26 via the modem 27.

The illustrated branch computer 90 _{j, k} stores historical information that is a characteristic of the securities of interest, such as past profit and price-revenue ratio, dividend history, and annual high and low prices.
Has RAM95. Such information can be obtained by a suitable keyboard 112 input (all quotes) at the workstation.
It is available on any workstation 110 connected to the branch computer 90 _{j, k} . The current stock price information in RAM96 and the history / corporate information stored in RAM95 are shown in FIG. Of course, two memories 95,
96 may be one in which one of such memories is divided into two, or one memory may be shared.

As a special information source that can be used in the system shown in FIG. 1, at least one source level 10 wired news source 24 is connected to various branch computers and area computers 50 and 90 via a ground communication line 25. Further, it supplies financial news to various workstations 110 via a branch computer. The currently available wired news sources shown in the figure are Dow Jones.
s) and Reuters. Also, the news information provided by news source 24 includes area computers, branch computers,
The output of the market indicator 35 may be multiplexed and radiated together for delivery to a workstation computer or the like.

The purpose of the present invention is to provide a market price indicator 35 and a wired news source.
To make the market information and news information generated by 24 available to workstations of various systems. That is, workstation 110
Users (such as brokers) have their own display device 107
It has a signal input keyboard 112 that can be used when specifying the information to be displayed on. As mentioned above, some of the market information is in RAM111 on the user's workstation.
It is stored in. The market price that the user does not have is
Under the control of the central processing unit 103 via the control port 105 _c of the multiplexer multiplexer / demultiplexer 105
Loaded from the branch computer 90 or area computer 50. The information displayed on the display device 107 may consist of only one field of information such as the market price and the flow of the market price display device, and may be displayed in multiple windows on the CRT 107 as in one embodiment of the present invention. You can also Furthermore, the format of the multi-window display can be changed according to the key input entered by the user. Methods of displaying multiple "windows" or fields on a single CRT screen are, of course, well known to those skilled in the art and can be purchased from IBM, Bell Labs, and the like.

FIG. 2 shows an example of a multi-window displayed on the display device 107 of the system workstation 110. The composite image includes a first field 142 that consists solely of the full New York Stock Exchange quotes (sequential stock trade messages for stocks for that stock). This field contains a series of messages, each of which consists of a stock symbol 143, a turnover 144 (in hundreds of shares), and a trade price 145. The price 145 may omit the first digit at the top, and the trading volume may be omitted on days when there are many transactions in order to prevent the market indicator from being unduly delayed. For example, considering the first trading configuration of the data field 142 of the market indicator displayed on the display device 107, looking at the market indicator, the stock 5000 share of the exchange symbol ABC is 90 3/4.
You can see that it was traded at the price of.

The display format in the multi-window selected by the user with the keyboard 112 is the second one specified by the user.
Contents of the market indicator (including "TICKER-2". According to an aspect of the present invention, the user sets a criterion to satisfy the transaction message from the market indicator 35 to create his own market indicator, It can also be displayed in the -2 window field 147. This criterion can be stored in the RAM 111 and can be used to limit transactions, such as only a prescribed securities list or transactions on a prescribed exchange. By restricting transactions by establishing such criteria, information regarding securities transactions that are completely uninteresting for the users of the workstation 110 are ignored, and only the limited information is focused, and You can slow down.

A display field 149 displays a new report from the news source 24 while scrolling, and a field 151 in the display device of the present embodiment includes limit limit excess information. The entries shown in Fig. 2 are the range of values stored in RAM111 (25 7/8)
Securities (MN 5) with final (close) price (25 5/8) outside
O) is shown. Bid and down limits are often used by brokers and investors as buying or selling terms and are of interest to both brokers and customers who own these securities. It will be.

The "monitor" field 153 now contains price information for a predetermined population of securities of interest to the broker. Each entry includes an identifier (stock symbol) 154, the market 155 the last trade was made in, an arrow 157 indicating whether the last trade was up or down, and currently available bid and ask bids 158. Finally, the “Balance” field 157 indicates that the designated stock (A) has the symbol entered by the user from the keyboard 112.
BC) quotes. When you read the entry shown in Fig. 2, the stock symbol followed by the identifier on the exchange (New York) that is the final trader of the securities, the arrow (upward) indicating the direction of the final trade, and the transaction price (90 3 /
4), the current ask and ask prices (90 5/8) and buy and sell quotes (90 7/8), and the exchanges on which these sell / buy quotes occurred (Sell-Boston Stock Exchange and New York Stock Exchange). , Buy-Ask-American Stock Exchange and Toronto Stock Exchange), buy / sell buy / sell volume (sell 60, buy 5), share of securities traded during the day (230,800), last trade time ( 12:02).

Other windows may be added to or overlapped with the display screen of FIG. For example, a field indicating a stored limit price is just one of many possible examples.

Each of the data fields shown in FIG. 2 can be independently displayed on the CRT screen while the user controls the keyboard 112. Also, as mentioned above,
It is also possible to identify one of the various multi-window formats using the keyboard 112 in a well known manner to display multiple data fields simultaneously.

As mentioned above, one of the objects of the present invention is to provide the information characterizing the securities of interest to each workstation 110 _{i, j, k} , especially its RAM, such as users of brokers and other workstations. It is to be stored in the storage device 111. To this end, the internal computer program represents a predetermined limited number (eg 300 for limited purposes, etc.) of the securities lastly requested for price information at that workstation. The security identifier and the price data are automatically stored in the fluctuation content RAM storage device 111 of the workstation of the person concerned. When a new quote is reached after the maximum number of workstations 110 (300) has been reached, the central processing unit 103 determines that the oldest securities of the limited population of stocks, namely 300 securities. Discards the least likely to be displayed after the new query made.

Via the market price display 35, the communication link receiver 98, the demultiplexer 105, and the central processing unit 103 of the workstation.
The price information stored in RAM111 automatically changes as new transactions are reported in the 300 monitored securities populations. The stored security price information automatically changes the display price of each security no matter where the security is displayed in the multi-window (field) of the display device 107. That is, when new price information is obtained for any stock, the display content of each window in which the security is displayed changes. For example, if the price of common stock with the stock symbol ABC changes on the display screen shown in FIG. 2, at least the “monitor” fields 153, “N
The display contents of the “YSE” market price display 142 and the “current market price” field 157 are changed, and new information obtained from the database of the workstation is stored in the RAM 111. When the limit price is exceeded in the final transaction, a message to that effect is displayed in the field.
Displayed at 151.

Referring now to FIG. 3, the RAM of workstation 110
An operating program is shown at 111 to maintain the database so that it can reflect the limited number (300) of entries last queried at that workstation. The program for dynamically controlling the storage device at the user's workstation 110 is stored primarily in read-only memory or RAM 109, but RA
It may be stored in the M111 storage device. Again, quotes are said to maintain in the variable RAM storage 111 of that workstation 110 the information about the 300 securities most recently queried (and thus most likely to be queried) at your workstation. Is a function of the dynamic storage algorithm. To this end, the RAM 111, which stores the stock symbols of the 300 (or less) recently queried securities, is the "least used" LRU.
Includes (least recently used) list. The last security queried is at the top or first position of the list, and the least queried symbol is (all 300 items full) unless the oldest one at the bottom of the list is deleted.
Assume that a new security that cannot enter the LRU is in a position that is first deleted when entered at the workstation keyboard 112. The process variable LRUSZ is maintained to indicate the quantity or number of items in the LRU list. Of course, the program used in the present invention may be written in an appropriate language that can be applied and stored in any digital processing device.

To illustrate the operation of the dynamic storage reallocation algorithm, assume that a broker or other user using workstation 110 _{i, j, k} shown in FIG. 1B wants to query for the desired security. He inputs the symbol corresponding to the security from his signal input keyboard 112 (function step 201 in FIG. 3). In the judgment step 205, it is judged by referring to the LRU table whether or not the newly input stock symbol is already on the LRU list. If there is (YES at decision step 205), the command message input from the keyboard 112 at the decision step 206 is read, and all market prices that the user does not have on the workstation 110 (things that have fallen in the past or derived (price / earnings ratio etc.) Information)), or whether you are requesting information about the so-called market price or trading volume at the user's location. If all market prices are required, the workstation 110 obtains history information from the history information storage device 95 of the branch computer 90 _{j, k} via the communication demultiplexer 105. If necessary,
Historical information at various levels with detailed content Branch computer RAM 95 and Area computer RAM 60
It may be dispersed between and. In any case, once the data is acquired from the RAM 95, it is displayed on the user's CRT display device 107 so that the user can know whether it is the full market price or the current market price (step 215).

If the other output is obtained at decision step 205, the requested stock symbol has not been recently queried at that workstation 110 _{i, j, k} , and
It is not in RAM 111 of 110 (decision step 2
05 NO). In this case, the desired inquiry content is obtained from the RAM 96 of the branch computer (or higher computer if necessary) ... Step 220. Depending on whether the input command entered by the user from the keyboard 112 specifies the whole market price or the current market price, in the judgment step 222, if the whole market price is required, all the information is obtained from the RAM 95 of the branch computer (step 224). However, skip this step if the current market price is all you need. In the next operation 227, the information just acquired is stored in the variation content storage device 111 of the user's workstation, and the predetermined position (eg FLA) is stored in step 229.
The flag bit of G) is set, and the process shown in FIG. 3 indicates that a security that has not been stored in the storage device 111 of the user's workstation 110 is being handled. As explained above, the market price information is displayed on the display device in step 215 in the form of the full market price or the current (limited) market price.

After displaying the information on the user's display 107, the symbol of the security that has just been queried by the user is placed at the top of the LRU list, and this security is added to workstation 110.
It indicates that it is the last security inquired by _{i, j, k} (step 217).

The remainder of the functional operation shown in FIG. 3 maintains the least used (LRU) list in the correct format and the list size variable (LRUSZ) at the correct value. To this end, decision step 219 examines the contents of the flag bit (FLAG) to determine if the last symbol processed was the one that was previously in the data table (if newer than ever). If yes, it will be NO in decision step 205, but if it has been listed before, it will be YES). If the flag bit is not set (decision step 219 NO), then the stock symbol (and its accompanying information) is already in the LRU list and the RAM 111 database, and at step 230 position 1 and beyond. Search the LRU list and delete the same symbol that appears second in the list. This symbol is deleted because it is listed higher than the second position in step 217, that is, the first in the LRU list.
It is useless to put two identical symbols, so discard them. This completes the dynamic storage reallocation operation shown in FIG. 3 for the data processing branch computer assumed in this embodiment. Therefore, it proceeds to the final point of the subroutine and transfers the control of the system to another operation.

If, in decision step 219, the flag bit is set (YES is assumed to be the symbol not on the LRU list), then in decision step 235 the LRU list is of maximum size (LRUSZ ≥ 300) is determined. If you can afford it, add the new symbol to the data table without removing the old symbol. Therefore, in step 240, the variable indicating the size of the LRU is increased by 1 (LRUSZ = LRUSZ
+1), the flag bit is cleared (step 242), and the process ends. If the LRU table is full (YES in determination step 235), the element at the bottom of the LRU list is deleted (step 237). After that, the flag bit is cleared (step 242) and the routine ends.

Thus, in the data processing mode shown in FIG. 3, the contents of the RAM 111 of the workstation 110 are the list of the last 300 types of stock symbols (LRU) inquired at that station.
To automatically maintain. The stock symbols with the latest reference time appear at the top of the list, and the oldest symbols at the bottom of the list. At this time, the symbols that were queried only once before the 300 types of quotes were input from the user's keyboard 112 are deleted.

The stock activations listed on the LRU list and the corresponding stock prices and other information may change from moment to moment depending on the user of the device 110 _{i, j, k} , and the way in which queries are entered varies by operator. As it seems, it is clear that the same time will be different for each system workstation. Therefore, the variation content storage device 111 provided in each workstation 110 stores the information that is most likely to be needed next by the user of each station. In this way, the user can quickly obtain the necessary information without asking the other system computer (excluding the "history" information), and the delay due to unnecessary communication and waiting time is eliminated.

Finally, the flowchart of FIG. 4 showing an operation program for dynamically updating the data of the RAM111 database of the user, which is the characteristic of the stock currently supplied to a certain user, will be described. That is, in FIG.
User RAM with current prices and other market data 1
Display screen of user's CRT107 loaded on 11 (Fig. 2)
FIG. 6 illustrates a method for providing current information for each of the components of FIG. For ease of explanation, for each element of the display screen (field or window in FIG. 2), the list of symbols currently of interest is RAM111.
A first list (LRU table) of the 300 most recently quoted quotes that exist in the market, a second showing who the bids are maintained for these securities
It is assumed that there is a list of, the list of contents displayed on the market price display, etc. Each list has a pointer to all the data for each security in the list. On the other hand, for all the stocks currently supplied, the list and the data table may be put together into one together with one or more identifiers recording the contents to be inquired about the stock data.

Looking at the flow chart shown in FIG. 4, in the first step 301, the market price is generated by the market price indicator 35, and the branch device 7
Cables 103 and demultiplexers 105 from 0, 80, 81
The stock symbol, price, trading volume, and other related information (market indicator message) supplied to the workstations 110 _{i, j, k} via the computer and read as the next input are read by the CPU of the computer. List of shares used in decision step 303 (ie LRU list, list for limit processing, etc.)
Refer to. If the security characterized by the quote message is not in these lists (decision step NO), control proceeds to decision step 320,
It is determined whether the stock is suitable for one of the display contents (142, 147, etc. in FIG. 2) of the market price display on the display screen of the user. If the transaction information reported by the quote 35 is suitable for one or more of the display contents at the workstation 110, then update the contents associated with this security in the database of RAM 111 (step 308). ) And reflect the final trade and closing price for that stock, and update everything related to that stock (windows and associated windowing storage) as necessary at step 310. Thus, as an example, assuming that a stock with trading information reported by the quotes exists in the LRU list and database, the reported information will be out of date for the security in the user's RAM111 database. It will be stored in that database instead of the data.

Assuming there are stocks to maintain in the limit table (supporting display field 151 of FIG. 2), decision step 312 determines whether the reported trade is above the limit range. If not exceeded (N in decision step 312)
O), control of the system moves to decision step 320 to process the display content of the market indicator. If the limit price has been exceeded (YES in decision step 312), a limit price excess message is displayed in field 151 in FIG. 2 and the user is instructed to take appropriate action. It will be readily appreciated that prices are considered for an upper and / or lower price range that suits the investment strategy of the user or the user's customer. Further, in step 317, the name, account number, telephone number, and even the user number are transmitted via the multiplexer 115, the branch computer modem 91, and all the communication devices interposed between the database 12 and the workstation 110. The workstation of (1) retrieves the necessary information from the customer master database 12 for all the customers who own the securities for which the out-of-limit message is displayed. The user can contact the owner of the securities in question from time to time to determine if any action should be taken, or to use the automatic action as appropriate.

Finally, at decision step 320, the message on the market dispute 35 in question is read and the user's workstation 110
Then, it is determined whether or not the flow 142 or 147 of the market price indicator should be displayed based on the criteria set by the user himself. If the criteria are met (YES in decision step 320), this message is added to one or more display stores of the market indicator suitable for that case and entered into the corresponding market indicator. To do. As described above, the standard of the market price indicator is defined by the user himself. If the user limits the content of the quote to a limited group of stocks, the quote criteria will only be met when the stock symbol in the entered message matches the desired symbol stored. become. Other criteria are simple such as displaying only trades on a particular exchange (a portion of the data sent by the quote 35). The message on the market display is not suitable for display on the market display on the user side (N in decision step 320).
If O), control returns to the beginning of FIG. 4 and waits (or transitions to another system function) until the next trading layer is supplied by the master quote 35.

In this way, the process shown in FIG. 4 maintains the data in the user's RAM 111 to be the latest in view of each application currently made in the unit, and the data displayed on the display screen is processed. Limit to only those stations 110 users want to get. The complex device shown in FIGS. 1A and 1B operates flexibly, monitoring and displaying only the information that the user of each workstation 110 desires to acquire and display. As a result, only a limited part of a very large amount of securities data can be accessed at high speed, and the information most likely to be inquired by the user according to the user pattern and individuality that varies depending on the operator of each workstation can be accessed at high speed. Will be able to access.

It is obvious that the above-mentioned apparatus and method are merely for explaining the principle of the present invention, and that various modifications and applications can be obtained by those skilled in the art without departing from the spirit and scope of the present invention. is there.
