Order information including trade desired data, such as the name of the brand desired to trade and the price, is transmitted to the stock exchange from the investor who wants to trade securities through the securities company. At this time, as a method for transmitting the order information, it is desirable to transmit the information in a predetermined format from the client 30 managed by the securities company to the exchange server 10 managed by the stock exchange via a communication network, but by communication means such as telephone and facsimile. Order information may be communicated, and the order information may be entered into the exchange server 10 by a stock exchange representative.

The exchange server 10 generates a record based on the order information transmitted as described above, and performs an update process of recording the record in the first recording means 13a (S101). It should be noted that contract information indicating the conclusion of a contract, which is a promise to perform a transaction, is transmitted, and the update process is also performed when the corresponding record record is deleted, and when the record record is canceled and corrected. Also, in order to prevent record records containing extremely large or small numerical values from being generated due to input mistakes, etc., set upper and lower limits on prices and quantities, and use order information that deviates from these upper or lower limits. It is also possible to prevent a record record from being generated.

When the updating process is performed as described above, the first
From the record records which are the same brand and order as the record records recorded or deleted in the recording means 13a, three record records with good price conditions including the best quote are selected, and based on the order information of the selected record records. A transmission record is generated (S102), and the transmission record is recorded on the second recording means 13b (S103). And step S10
Returning to step 1, the same processing is repeated.

If a transmission record is recorded in the second recording means 13b, a transmission record having the latest generation time is searched for each brand and trade order, and is set as the first transmission record (S104). Further, the first recording means 13b
All transmission records having the same brand name and trade order data as the transmission record are searched as second transmission records (S105). When the second transmission record is not detected by the search in step S105 (S106: N), it is determined that there is no stale information, and the first transmission record is transmitted to the information providing server 20 (S109).

When the second transmission record is detected by the search in step S105 (S106: Y), the generation time of the second transmission record is compared with the generation time of the first transmission record, and the second transmission record is transmitted to the first transmission record. It is confirmed that the record is older than the record (S107), and it is determined that the information is stale, and is deleted from the second recording unit 13b to stop the transmission of the second transmission record (S108). Then, the first transmission record having the latest generation time is transmitted to the information providing server 20 (S109). The transmission record with the oldest generation time may be searched and used as the first transmission record. In such a case, the transmission record in which the data of the first transmission record and the brand and trade order are the same is searched for , The transmission record with the latest generation time is reset as the first transmission record, the other transmission records are deleted as the second transmission record, and only the first transmission record with the latest generation time is deleted. Send

The information providing company uses the information providing server 20 to receive the transmission record transmitted from the exchange server 10 (S201), and stores the transmission record in the recording means 23.
(S202). Then, reception completion data indicating the reception completion is generated (S202), and the reception completion data is transmitted to the exchange server 10 (S203). Exchange server 1

As described above, each time information that requires updating of a record record such as order information and contract information is transmitted, the processing of steps S101 to S103 is performed, and the processing of steps S104 to S111 is performed in parallel with these processing. As long as the transmission record is recorded in the second recording means 13b, the operation is sequentially performed.

The securities company uses the client 30 to request desired order information from the information providing server 20 (S30).
1) When the information providing server 20 receives the request (S
204), a transmission record including the corresponding order information is transmitted (S205), and the client 30 receives the transmission record (S302), and outputs the order information obtained by the received transmission record from the output means 37 such as a monitor. Output (S303).

FIG. 5 is an explanatory diagram showing the order information output from the monitor. As shown in FIG. 5, the monitor outputs prices and quantities of three pieces of order information with good price conditions including the best quote for each brand and order in the form of a list. The transaction is reviewed based on the information that changes every moment, and the details of the transaction are reported to the stock exchange via a securities company.

In the above embodiment, the transmission record is generated based on three record records having good price conditions. However, the present invention is not limited to this, and the transmission record is generated based on one record record having the best price. Further, in this form, when the generation time of the transmission record is compared and deleted, and when there is a transmission record called indicative information in which only the latest transmission record and the price data are different from each other, this form is used. The transmission records may be excluded from the deletion target, and the transmission records may be transmitted in the order of generation time.

The present invention is not limited to the form of transmitting the order information of securities, but may be any information whose contents are updated at any time and only the latest contents are significant, for example, transactions of convertible bonds, futures products, and financial products. The information may also be information on the target, and further on the course of the sport.

Then, a transmission record is directly transmitted from a server computer managed by a stock exchange to a client computer managed by a securities company, that is, a communication system including a transmission device and a reception device without including a relay device. Is also good.
