Investment Information Sorting and Transfer Server and Inter-operating Module for Cyber-Stock-Investment Programs}

The present invention relates to an electronic commerce implementation technology, and more particularly, to an electronic commerce technology that classifies and transmits investment information for cyber stock trading by item code, and automatically links item news with a stock trading program in real time. .

Securities trading using a computer communication network such as the Internet was activated in 1997, when the ground rules were established to enable electronic orders using computers in addition to documents and telephones.Now, cyber stock trading services using the Internet are more popular than securities trading using PC communication. It is. In addition to the increased convenience of the cyber stock trading, investors can obtain investment information in real time through the Internet, and securities companies can acquire new customers through the Internet, thereby reducing the cost of installing additional branches. It is possible to diversify the securities business by activating the trading of various financial products. Domestic cyber stock trading is performed by a securities company receiving a trading order from an investor via the Internet and delivering the order to the stock exchange.

For cyber stock trading, investors should use Internet stock trading programs such as HTS (Home Trading System) or WTS (Web Trading System) provided by securities companies. HTS is an application type program, which makes the user interface inconvenient and difficult to process multiple tasks on one screen at the same time. WTS is a web site that supports transactions and it takes a lot of time to load pages according to the speed of the system. It is difficult to update information in real time, and it is difficult to simultaneously view multiple pages due to the characteristics of a web browser.

Meanwhile, for investors in cyber stock trading, real-time investment information necessary for stock trading and accurate investment timing using this information are very important. However, until now, since the Internet stock trading program did not automatically link real-time investment information with orders, there was a limit in ensuring accurate investment timing by using investment information in real time.

An object of the present invention is to overcome the problems of the prior art, it is to link the information necessary for investment and the stock trading program for investors in real time.

Another object of the present invention is to enable investors to place timely trading orders in cyber stock trading through a computer communication network.

Embodiment

1 is a block diagram illustrating a connection structure of an investment information classification and transmission server and a cyber stock trading program interworking module according to the present invention.

In FIG. 1, the content collection module 10 collects investment information in the form of digital content from an information providing site (eg, a web site) connected through the Internet, and transmits the investment information to the server 20. The news classification and transmission server 20 includes a news processing thread 22 and a news transmission thread 24, and classifies and transmits stock investment related information sent from the content collection module 10 to the interworking module 30. The interworking module 30 is installed in the form of software in the investor's personal computer system, for example, and receives investment information received from the server 20 and transmits the stock information to the stock trading program 40 as an item code. The stock trading program 40 is installed in a computer system in which the interworking module 30 is installed, and transmits the order data to the securities company computer system 50, and the securities company computer 50 transmits the order of the investor to the stock exchange system ( 60, and returns the conclusion information sent from the stock trading system 60 to the stock trading program (40).

The content collection module 10 collects the necessary information from the web content and processes it into data in the form of, for example, XML (eXtensible Markup Language), and then transmits the information to the server 20 using, for example, a window message. The programs of the content collection module 10 and the news separation and transmission server 20 are different programs, and communication between processes is required for communication between these programs. In the case of a Windows platform, a window message is best used for communication between processes. Since it is one of the simplest, the present invention has been described as a data transmission occurs via a window message. Thus, it will be readily apparent to one of ordinary skill in the art that the communication between processes may be possible using other means than window messages.

In the news classification and delivery server 20, the news processing thread 22 processes a plurality of distributed threads when a large amount of data is transmitted from the content collection module 10, and the content collection module 10. It serves to process the transmitted data format, for example, window message data into data of a format suitable for a client (eg, the interlocking module 30), and transmits a certain amount of content to a client that has made an initial server connection as described below. It serves to process data (eg 1,000 content). The news transmission thread 24 transmits the processed content in real time, for example, in XML data format, to the requesting client 30 using multiple threads and order association technology. In FIG. 1, a thread refers to a unit of a program handled by a multitasking function, and a set of threads becomes a process.

According to the content collection module 10, the news classification and transmission server 20, and the interworking module 30 of the present invention having the structure illustrated in FIG. 1, investment information necessary for stock investment (eg, stock news) is included. By using the item code to automatically transmit the item code to the stock trading program 40, it is possible to increase the convenience of cyber stock trading, shorten the investment time and enable timely investment in real time.

Although the content collection module 10 is shown in a separate configuration from the news classification and delivery server 20 in FIG. 1, the content collection module 10 may be included in the server 20 according to a method of implementing the invention. have. That is, if the person skilled in the art to which the present invention pertains, it is also possible to implement enough to implement the function of the content collection module 10, the news classification and transmission server 20 shown in FIG. It will be readily understood that such embodiments are not shown and described in separate drawings.

Detailed implementation examples of the content collection module 10, the news classification and transmission server 20, and the interworking module 30 illustrated in FIG. 1 will be described below with reference to FIGS. 2 to 4.

2 is a block diagram illustrating a detailed implementation of the content collection module 10 according to the present invention.

In FIG. 2, the content collection module 10 includes a worker thread 12, an external variable database 14, and a Visual Basic Script 16 (hereinafter referred to as VBScript). Worker threads 12 serve to pull content from numerous sites 70, 71, 72, ... 73 that are connected to the Internet. The content collection module 10 uses a program function having an internet session related function such as HTTP, FTP, and the like. For example, MFC classes (ClnternetSession, CHttpConnection) are used to connect to an HTTP server, and the scripts in the web site ((70, 71, 72, ... 73) can be downloaded via the HTTP protocol to download the contents of the script. For example, an attempt to invoke a script may use API functions that enable data communication using, for example, Internet protocols, for example, InternetOpen, InternetConnect, HttpOpenRequest, etc., and control of a web browser (e.g., Internet Explorer). Script calls can be made by applying the HTTP protocol to Windows Sockets.

The extracted script is finely decomposed by variables given in the database 14, and it is also possible to control the content by using the VBScript 16 as well as external variables in the decomposition process. External variables or VBScript can be modified to suit different Web sites (70, 71, 72, ... 73) that have been modified without any source modification or recompilation. The content collection module 10 may be implemented as a software program. The content collection program may be implemented when an administrator creates a VBScript code so that the program may be equipped with an engine capable of processing VBScript and extract necessary information from the collected content. Parses VBScript and gathers the necessary information (the result of parsing the content). In this case, the external variable can be set and corrected by the administrator. The extracted content is sent to the news classification and delivery server 20, which may be output on the screen.

In one embodiment of the invention, the connection to the HTTP server of the content collection module 10 is made in the worker thread 12. This may prevent the lock of the executable file of the content collection module 10 program (eg, InterWeb.exe) when invoking the script. It also loads VBScript DLLs using standard interface conventions between applications and technologies that expose their functionality to other applications so that they can use it. As the standard interface protocol between the applications, for example, Microsoft's Component Object Model (COM) may be used. Here, the COM server is a COM component, which may be in the form of a DLL or EXE. COM clients are applications that use COM components. The ability to expose one's own functionality to other applications so that they can use it is also known as automation. For example, InterWeb.exe, described above, loads VBScript.dll and asks VBScript.dll to interpret it. . VBScript.dll is interpreted by the VBScript engine and returned to InterWeb.exe. InterWeb.exe prints the result back to the screen or proceeds to the next step. Therefore, VBScript.dll becomes a COM server, and InterWeb.exe becomes a COM client because it loads and uses the VBScript.dll COM component. Loading a VBScript DLL by building a COM server and a COM client using COM and automation is a function of interpreting a given VBScript externally and returning the result value to a content collection program. It's all possible with scripts.

3 is a block diagram showing a detailed implementation of the news classification and transmission server according to the present invention.

The news classification and transmission server 20 is composed of a news processing thread 22, a listen thread 20, a listen thread, and a plurality of transmit and receive threads 23, 25, 27, 29 connected thereto. The news classification and transmission server 20 may be implemented in a combination of hardware and software, for example, Microsoft Windows 2000 platform. The server 20 preferably uses a thread pool and a window message to accommodate a large number of investors at the same time, and the content collection module 10 may be configured using multiple threads and order linkage technology. ), It is desirable to send the news sent in the real time only to authenticated clients. That is, the news data processed by the news processing thread 22 of the server 20 is distributed to individual transmit / receive threads 23, 25, 27, 29 by separating the client for each thread by the listen thread 21 to distribute the data. send. The listen thread 21, for example, in the case of socket communication, when hundreds of clients are connected at the same time, number the client's connection order and transmit the request data to the client through a plurality of threads in order to transmit the data accurately in real time. The individual transmit / receive threads 23, 25, 27, and 29 are connected to the interworking modules 1 to 4 (30a, 30b, 30c, and 30d) of the investor computer through the communication network 80 to transmit data. Therefore, the maximum number of clients can be accommodated at a minimum cost, and the use of multiple threads can increase the information transfer capability and the client's connection speed. In order for the individual investors 30a to 30d to access the server 20, user authentication is required, and such authentication and news data may be encrypted. On the other hand, the user authentication process can increase flexibility by using an application service provider (ASP) of the web server, and communication between the client and the server needs to ensure future scalability by using an XML type protocol.

The interworking module 30 may include a server connection unit 31, a classification unit 32, a content buffer 33, a buffer manager 34, a first condition input unit 35, a user search processing unit 36, and a second condition input unit ( 37), and receives the investment information news from the news classification and transmission server 20 (31) and delivers the item code to the stock trading program (40). The server connection unit 31 of the interworking module 30 is connected to the server computer 20 based on the TCP / IP (Transmission Control Protocol / Internet Protocol) protocol, and receives the user's ID and password and encrypts the user ID and password. Request the server 20 for authentication. After the authentication process, the interworking module 30 receives a predetermined amount of content, for example, 1,000 contents, from the server 20 as the investment information news.

In FIG. 4, the classification unit 32 classifies the received news content in real time for each item and stores it in the item content buffers 33a, 33b, ... 33n. In the present invention, it is preferable to shorten the time taken to retrieve specific data by using a hash table, for example, which manages news content in a vector format index. In order to facilitate reading and writing data to a hash table, for example, CMap, which is a kind of MFC class, is used, and an address of each content buffer can be stored. The index management of the content and the address storage of the content buffer may be performed, for example, by the buffer manager 34. By configuring the interworking module 30 in this way, it is possible to query several codes as soon as new content arrives. The content buffer 33 temporarily stores data input in real time, and the buffer manager 34 manages and deletes the contents of the buffer.

The first condition input 35 allows each time a new stock news arrives to retrieve it in real time before storing it in the buffer. The user search processor 36 searches for news items stored in a buffer according to a user's search condition input through the second condition inputter 37 and controls the buffer manager 34. The user search processing unit 36 may directly access the buffer 33. For example, when the user sets a regular search code, the user search processing unit 36 searches the buffer 33 without the intervention of the buffer manager 34. To save time. The buffer manager 34 and the first condition input unit 35 display search results 38 according to a user-specified condition and automatically transmit the item code to the stock trading program 40.

5 illustrates a user interface of a linked module which can be implemented according to the present invention and a stock trading program connected thereto.

In FIG. 5, the user interface 30a of the interworking module shows the contents and the list of the item news received from the news classification and transmission server 20. News of the user's choice, for example, the news' Pharmaceutical, the lowest real trading price corresponding to the item code '00640'. . In the case where -SK 'is expected to deteriorate profits (90), the corresponding item code is automatically transferred to the item code input field 92 in the order window of the user interface 40a of the stock trading program.

As can be seen in Figure 5, when the stock news arrives, the stock trading program automatically delivers the stock code to ensure fast sell and buy time. In addition, by outputting the contents of different news content providers through a single interface, the required investment information can be obtained quickly and accurately. When the news arrives, the user interface may be configured to maximize the extraction and determination of information through a sound alarm, a keyword search, and a screen output color change according to the news.
