Abstract: A transaction assisting apparatus capable of automatically transacting chain orders. Chain order input unit accepts entry of a chain order and supplies the input chain order to chain order storing unit to be stored therein. Order detecting unit is supplied with an input buy order, and if the buy order placed is for the chain order, it notifies chain order processing unit that the buy order has been placed for the chain order. The chain order processing unit performs a selling/purchasing process with respect to the chain order for which the buy order has been placed. When the selling/purchasing process is completed, deleting unit deletes the corresponding chain order from the chain order storing unit. In the event the price of chained goods has changed, price changing unit changes the price of chain goods correspondingly in an interlocked manner. Display unit selectively displays, on display units, only those chain orders which satisfy certain conditions such as the presence of chained goods.

Abstract: A system and method which support securities transactions, preventing the market price from fluctuating when introducing a new set of securities to the public. In this trade support system, a trade processing unit processes buying and selling orders received online from customers' terminals. Each time a deal is completed, the trade price acquisition unit takes in the resultant trade price. A price evaluation unit determines whether the acquired trade price meets the offering price that is suggested in the prospectus of the public offering. If the former is lower than the latter, the price evaluation unit so notifies a trading order placement unit. A subscription period checking unit, on the other hand, checks whether the present date and time is within the subscription period.

Abstract: A credit account management system comprises a refund method management unit, and a credit limit setting unit. The refund method management unit receives the designation of a refund method of the outstanding credit-loan amount in the credit account after integration from the user, and sets the refund method of the outstanding credit-loan amount in the credit account after integration. After credit accounts are integrated, the outstanding credit-loan amount is refunded according to the refund method set by the refund method management unit. The credit limit setting unit compares the outstanding credit-loan amount in the credit account after integration and a target credit limit which is expected to be given in the credit account after integration, and sets a credit limit in the credit account after integration based on the comparison result.

Abstract: A deal processing apparatus, which clinches a deal by intermediating a sell order and a buy order, comprises a sell/buy determining unit clinching a deal by determining a pair of sell and buy orders with which a deal is to be clinched. The sell/buy determining unit obtains a sell/buy profit by clinching a first deal with sell and buy orders in which a desired sell price is lower than a desired buy price. Then, the sell/buy determining unit clinches a second deal with sell and buy orders in which a desired buy price is lower than a desired sell price. A quantity to be dealt in the second deal is determined so that a sell/buy loss that a broker suffers in the second deal does not exceed the sell/buy profit that the broker obtains in the first deal. In this way, a deal is clinched while reducing the risk that a broker who intermediates orders with this dealing method suffers a sell/buy loss, even if a desired sell price of a sell order does not match a desired buy price of a buy order.

Abstract: A background communication system is provided which is capable of transferring files in the background without the need to use a multithread OS. A LAN board and an external disk, which temporarily stores files received from a LAN and files to be transmitted to the LAN, are connected to a bus expansion slot of a personal computer, and this expansion slot is separate from that to which standard components for the personal computer are connected, whereby the LAN-related elements are separated in terms of hardware from the bus for controlling the personal computer. Network control means performs time-division multiplex control on the buses to permit background file transfer.
