Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stock price information transmitting / receiving apparatus having a mail sending function for notifying stock price information to a portable terminal device. [0002] Stock price information is transmitted from an information provider several hundred times per second as real-time stock price information. Transmitting all of this information to the portable terminal device imposes a heavy burden on the information providing system, and at the same time, the burden on the portable terminal device that receives it. For this reason, for example, as disclosed in Japanese Patent Application Laid-Open No. 2001-189749, a method is set in which alert conditions are set for information required by each mobile terminal device, and only information meeting this condition is transmitted to the mobile terminal device. Are known. FIG. 3 shows a general configuration of a conventional mail system having an alert information setting function. In FIG. 3, the stock price displayed on the stock exchange 1 is collected by the information providing company 2 via the stock price reporting line 7 and transmitted to the stock price information transmitting / receiving device 8 'as real-time stock price information.
The transmitted real-time stock price information is received by the data receiving server 3 in the stock price information transmitting / receiving device 8 'and stored in the real data storage unit 4 in the database server 9'. On the other hand, alert information is transmitted from the portable terminal device 6, and alert information is set in the alert information setting section 11 in the database server 9 'via the mail server 5 in the stock price information transmitting and receiving device 8'. The real-time stock price information stored in the real data storage unit 4 changes every moment, and the real-time stock price information is sequentially compared with the alert information set in the alert information setting unit 11 in the mail server 5. If the comparison result satisfies the above alert information condition, the stock price information at that time is transmitted to the portable terminal device 6 as data. As described above, a huge number of calculation processes are required to execute a comparison process of all data with the above-mentioned alert information, a processing device having a high-performance computer is required, and a high-cost system is required. It becomes. In addition, information is constantly received on the portable terminal device 6 side, and data check becomes troublesome. To avoid this problem, real-time stock price information continuously sent continuously is sampled at regular time intervals, and alerts are calculated for the sampled data to relax the specifications of the processing device and reduce the price. It is also possible. However, in this method, information in a portion that falls within the sampling interval is omitted, and the reliability of alert detection is reduced. [0005] As described above, in the prior art, there has been a problem of mutually contradictory mutual relations that when the system construction cost is reduced, the alert detection reliability is also reduced. It is an object of the present invention to solve this problem and to provide a stock price information transmitting / receiving apparatus that does not cause a decrease in the reliability of alert detection due to missing data even if the computer specifications of the processing apparatus are relaxed for cost reduction. . In order to achieve the above object, the present invention has the following configuration. That is, real-time stock price information transmitted from the stock price information providing company is received by the data receiving server, and the database server extracts necessary data based on the alert information set in advance on the mobile terminal device side. Is transmitted to the mobile terminal device. Here, the database server includes a real data storage unit for sequentially storing the received real-time stock price information, and a preset sampling period (for example, one minute period) within a predetermined time length (for example, 20 minutes).
And a delay data storage unit for storing the sampling data extracted in the step (a) and the sampling data for a shorter time (for example, 5 minutes) shorter than the predetermined time immediately before the present time. The short-term data storage unit for storing short-time data (called "time" bar, for example, 5 minute bar) in which the highest and lowest stock prices are updated, and transmitted from the portable terminal device side. And an alert information setting unit for setting and storing the alert information. The present invention will be described below in detail with reference to the drawings. FIG. 1 shows a configuration of a mail system having an alert information setting function according to the present invention. The stock price information generated in the stock exchange 1 is transmitted to the information providing company 2 via the stock price reporting line 7, and transmitted from the information providing company 2 to the stock price information transmitting / receiving device 8 as real-time stock price information. In the stock price information transmitting / receiving device 8, the transmitted real-time stock price information is received by the data receiving server 3, and further sent to the real data storage unit 4 as update data. Up to this point, the configuration is the same as that of the conventional method, but in the present invention, as described below, the configuration of the database server 9 is different from the conventional configuration. In other words, a total of 20 samples are extracted from the real data stored in the real data storage unit 4 for 20 minutes at 1-minute intervals, and this is used as a total of 20 data of 20-minute delays 1 to 20 to store the 20-minute delay data. The data is sequentially stored in the unit 12. This gives 2
The operation of deleting old data and replacing it with new 20 data is repeated in a 0-minute cycle, and a 20-minute delay database having the latest 20-minute data is always stored in the 20-minute delay data storage unit 12. . Next, the 20-minute delay data storage unit 1
2 is registered in the memory as the highest value and the lowest value of the current value from the latest five minutes of the data stored in 2, that is, the data corresponding to the latest five minutes (that is, five data).
In the securities industry, this is referred to as a five-minute bar, and the part in which this data is registered is hereinafter referred to as a five-minute bar data storage unit 13. FIG. 2 is a table for explaining this process. The real data indicates instantaneous data at the present time, and the 20-minute delay 1 indicates data one minute before. Further, the 20-minute delay 2 indicates data two minutes before the present time, and similarly, 20 data are stored in the 20-minute delay data storage unit 12 in the same manner. Further, the 5 minute data storage unit 13 stores a 20 minute delay 1 to a 20 minute delay 5
Up to five data items are stored. In FIG. 2A, for example, when the brand code 6756 is considered, the highest value is “800” of the 20-minute delay 1 when the data of the item of the current value in the past 5 minutes is retroactively examined. The low price is “780” for 20 minute delay 2. Further, when considering the brand code 6501, the highest value is the maximum value of the 20-minute delay 2 moving from 1350 to 1400, so the highest value of the 5-minute bar data is “1400”, and the lowest value is 1350 of the real data. Yes, today's lowest price is 1250, and there is no movement in the latest 5 minutes, so the lowest price is "13
In this way, the five-minute data relating to each brand is stored in the five-minute data storage unit 13, and the data is updated. The updated data is stored in the portable terminal device 6.
The mail server unit 5 compares the alert information transmitted from the side with the alert information set in the alert information setting unit 11 and transmits data that matches the condition based on the alert information to the portable terminal device 6 side. By updating the data using the 5-minute data in this manner, the sampling interval of the real-time stock price information can be extended to reduce the load on the processing device, and at the same time, the data can be captured at short intervals immediately before the sampling point. Therefore, data loss can be reduced. As described above, according to the present invention, since sampling is performed using a five-minute bar, data loss due to normal sampling can be reduced and the frequency of access to real data can be reduced. As a result, the specifications of the used processing apparatus were relaxed, and the apparatus price could be reduced.
