Then, the user inputs the order unit price (limit price) in the text box 803g (step S140). When the user selects (clicks) the confirmation button 803h, the user terminal 100 identifies the exchange code indicating the stock code, the trading category (buy, sell), the number of shares to be ordered, the order unit price (limit price), and the exchange. Order information including information and the like is transmitted to the input receiving unit 210 of the domestic securities company server 200. In this example, the user terminal 100 has a purchase order with the content “Purchase stock of“ 1000 shares ”of the stock with the stock code“ 1234 ”at the Hong Kong Stock Exchange at the unit price (limit price)“ 46 yen ””. Is sent to the input receiving unit 210.

  On the other hand, when the user selects (clicks) the cancel button 803i, the user terminal 100 erases the contents entered in the text box 803e, text box 803f, and text box 803g on the foreign stock purchase input screen. Note that the currency unit of the order unit price (limit price) input in the text box 803g of the order unit price (limit price) input field 803d is “Japanese yen (yen)”, which is the same as the settlement currency in the above account of the user in this example. . Therefore, the price entered as the order unit price (limit price) corresponds to the order price in the settlement currency.

  The so-called “market order” cannot be made in the trade order for the Hong Kong market. For example, when placing a trade order in the stock market where “market order” is possible, the display content output unit 230 acquires the foreign stock. Instead of the order unit price (limit price) input field 803d, an order input field having a pull-down for selecting a limit order and a market order may be displayed on the input screen.

  When receiving the order information from the user terminal 100, the input receiving unit 210 outputs the received order information to the order price converting unit 260. When the order information including information indicating the order price in the settlement currency (Japanese yen) is transferred from the input reception unit 210, the order price conversion unit 260 acquires the exchange rate from the exchange rate storage unit 240 (step S150). . Then, based on the acquired exchange rate, the order price conversion unit 260 converts the order price in the settlement currency included in the order information into the order price in the transaction currency (step S160).

  In this example, since “Hong Kong” is selected in the market selection field 802a of the foreign stock main menu screen, the transaction currency is “HK dollar (HK $), which is a currency used for foreign stock transactions in the Hong Kong market. ) ”. Therefore, in step S150, the exchange rate acquired by the order price conversion unit 260 from the exchange rate storage unit 240 is calculated by dividing Japanese yen by Hong Kong dollars, for example. Then, the order price conversion unit 260 obtains the order price in the transaction currency by dividing the order price in the settlement currency by the exchange rate.

  In step S160, the order price conversion unit 260 acquires the step value stored in the step value storage unit 250 and converts the order price in the settlement currency to a value less than the step value in the order price in the transaction currency. May be rounded by rounding down, rounding up, or rounding. Further, in this case, the order price conversion unit 260 may round the value less than the above-mentioned increment value based on conditions (round down, round up, round off) set in advance by the user, and round down the order price in the above transaction currency. The above condition may be changed when the input receiving unit 210 receives an input from the user as to which of at least two of rounding up, rounding up, and rounding.

  In step S160, the order price conversion unit 260 acquires the exchange rate stored in the exchange rate storage unit 240, and the exchange rate is designated by the user for each predetermined fluctuation range or each order. If the change is more than the fluctuation range, the contents of the purchase order including the order price in the transaction currency corresponding to the order price in the settlement currency may be corrected on the condition.

  The order price selection unit 270 calculates a plurality of order price candidates in the transaction currency that should correspond to the order price in the settlement currency based on the order price in the transaction currency included in the order information from the order price conversion unit 260 ( Step S170). Here, the order price selection unit 270 may calculate by rounding off, rounding down, or rounding up a value less than the step value in the calculated order price candidate in the transaction currency. More specifically, the order price selection unit 270 rounds off a value less than the step value in the order price in the transaction currency obtained by converting the order price in the settlement currency received from the user based on the exchange rate; Alternatively, a price obtained by adding the increment value by the increment value (or a multiple of the increment value) or a subtracted price may be calculated as a candidate order price in the transaction currency. In this case, a plurality of order price candidates are calculated in a transaction currency in which the value less than the step value is 0.

  The order price selection unit 270 outputs the order information including the calculated plurality of candidates to the display content output unit 230. When the order information is input from the order price selection unit 270, the display price output unit 230 uses the order information. The foreign stock purchase confirmation screen (limit order) corresponding to the order information is displayed on the display unit 110 of the person terminal 100 (step S180).

  FIG. 10 is a diagram illustrating an example of a foreign stock purchase confirmation screen (limit order). This foreign stock purchase confirmation screen (limit order) includes a stock code display field 804a, a market display field 804b, an ordered stock number display field 804c, an order unit price display field 804d, an approximate delivery price display field 804e, an order button 804f, An input request button 804g is displayed. In the stock code display field 804a, the market display field 804b, and the ordered stock number display field 804c, the market code selected on the foreign stock main menu screen and the stock code entered on the foreign stock purchase confirmation screen (limit order) are displayed. And the number of stocks ordered.

  In addition, an order unit price candidate display window 804h in which a scroll bar 804i is arranged is arranged in the order unit price display field 804d. In the order unit price candidate display window 804h, a plurality of order price candidates in the transaction currency are displayed based on the order unit price (limit price) input on the foreign stock purchase input screen. In this example, since “Hong Kong” is selected in the market selection field 802a of the foreign stock main menu screen, the transaction currency is “HK dollar (HK $), which is a currency used for foreign stock transactions in the Hong Kong market. ) ”. Therefore, all the candidate order prices in the transaction currency are displayed in Hong Kong dollars (HK $), which is the transaction currency of stocks in the Hong Kong market.

  By the way, the order unit price (limit price) “46 yen” in this example is approximately 3.1724 Hong Kong dollars (HK $) when the exchange rate of Hong Kong dollars to Japanese yen is “1 Hong Kong dollars (HK $) = 14.5 yen”. ). Here, in the Hong Kong market, the step value (nominal value) in the order of stocks whose order unit price is 0.5 to 10 Hong Kong dollars is 0.01 Hong Kong dollars. Therefore, in this example, “3.170HK $” rounded off the value less than the step value as the order price candidate in the transaction currency closest to the order price (limit price) “46 yen” is the order price candidate display window. It is displayed at 804h.

  Furthermore, in addition to the candidate for the order price in the nearest transaction currency, the price obtained by adding the above increment to the candidate price by the above increment, that is, HK $ 0.01 or subtracting the order price in the transaction currency. Are displayed in the order unit price candidate display window 804h. Here, as a candidate for the order price in the closest transaction currency, a price that is rounded down or rounded up may be displayed in the order unit price candidate display window 804h.

  When the trade order is a “buy order” as in this example, the display content output unit 230 displays a plurality of candidates for the order price in the transaction currency in the order price order in the order unit price candidate display window 804h in ascending order. It is preferable to display with priority. For example, the display content output unit 230 may display the plurality of candidates in ascending order of price from the bottom of the order unit price candidate display window 804h. Further, in this case, the display content output unit 230 displays the order price candidate in the closest transaction currency at the bottom of the order unit price candidate display window 804h and moves upward in the order unit price candidate display window 804h. You may display the price which becomes large sequentially in the range of the said step value from the said nearest price as a candidate of the order price by the said transaction currency.

  On the other hand, when the trade order is a “sale order”, the display content output unit 230 displays a plurality of candidates for the order price in the transaction currency in the order unit price candidate display window 804h in the order from the highest order price. Is preferred. For example, the display content output unit 230 may display the order price candidate display window 804h in descending order of price. Further, in this case, the display content output unit 230 displays the order price candidate in the closest transaction currency at the bottom of the order unit price candidate display window 804h and moves upward in the order unit price candidate display window 804h. You may display the price which becomes small in the range of the said step value from the said nearest price as a candidate of the order price by the said transaction currency.

  Further, as in this example, a so-called “market order” cannot be made in a trade order for the Hong Kong market, but for example, when placing a trade order in a stock market where “market order” is possible, the display content output unit 230. May not display the order unit price candidate display window 804h on the foreign stock purchase confirmation screen (limit order).

  The display content output unit 230 displays, in the order unit price candidate display window 804h, a plurality of candidates for the order price in the transaction currency and a price obtained by converting the price of each candidate into Japanese yen (settlement currency) using the exchange rate. Display. Note that the number of order price candidates in the transaction currency is not limited to three in this example, and may be one, two, or four or more. Further, even when all of the order price candidates in the transaction currency cannot be displayed in the order unit price candidate display window 804h, the user scrolls the scroll bar 804i on the foreign stock purchase confirmation screen (limit order). , All candidates can be displayed.

  In this example, the order price to be ordered by the user from among a plurality of candidates for the order price in the transaction currency displayed on the order unit price candidate display window 804h by the input unit 120 of the user terminal 100, for example, is “3. When “170 HK $” is selected (step S190), the user terminal 100 and the display content output unit 230, as shown in FIG. Are displayed separately for each candidate display portion. For example, the user terminal 100 and the display content output unit 230 may display only the display portion of the selected order price candidate among the plurality of candidates by color coding or shading.

  In addition, when the user selects a specific candidate from among the plurality of candidates, the user terminal 100 and the display content output unit 230 estimate the order required for the purchase order based on the order price in the transaction currency selected by the user. The delivery price is displayed in both the transaction currency (3,170HK $) and the settlement currency (45,965 yen) in the approximate delivery price display field 804e. In this example, if the balance of the user's account is less than the above approximate delivery price, a message such as “Exceeds available for purchase” at the bottom of the foreign stock purchase confirmation screen (limit order). May be displayed and the order button 804f may be locked so that it cannot be selected.

  On the other hand, in the case of a sale order, the user terminal 100 and the display content output unit 230 notify the user when the sale order with the order price in the transaction currency selected by the user is filled in the approximate delivery price display field 804e. The amount expected to be paid is displayed as an approximate delivery price. In addition, the approximate delivery price displayed in the approximate delivery price display field 804e includes the exchange fee between the above settlement currency and the above transaction currency, the trading fee of domestic brokerage firms, and the commission of brokerage firms in each country that carry orders. May be displayed in advance, or the fee details and the like may be displayed in the approximate delivery price display field 804e.

  After the user confirms the approximate delivery price displayed in the approximate delivery price display field 804e, for example, when the order button 804f is selected (clicked) by the input unit 120 of the user terminal 100 (step S190), the user terminal 100 transmits the order confirmation information to the input receiving unit 210. When the order confirmation information is transmitted from the user terminal 100, the input reception unit 210 receives the order confirmation information and outputs the order confirmation information to the ordering unit 280. When the user selects (clicks) the re-input request button 804g, the user terminal 100 and the display content output unit 230 may cause the display unit 110 to display the foreign stock purchase input screen again.

  When the order confirmation information including information indicating that the purchase order is based on the order price in the transaction currency selected by the user from the input receiving unit 210 is input from the order receiving unit 210, the order in the transaction currency by the user is input. Order information including information indicating price confirmation and order confirmation is transmitted to the transaction system 20. As a result, a purchase order having the above contents is placed in the transaction system 20 (step S200).

  In the transaction system 20, the order brokerage unit 410 of the foreign securities company server 400 transmits the ordering information transmitted from the ordering unit 280 to the order processing unit 510 of the stock exchange 500. The order processing unit 510 of the stock exchange 500 executes the purchase order transaction based on the order price specified in the ordering information specified by the order information from the order brokering unit 410 and the number of shares and the transaction currency (step S210). In addition, when the content of the order information transmitted from the order broker 410 is the content corresponding to the sales order, the order processing unit 510 sets the order price in the brand, the number of shares, and the transaction currency specified in the order information. Based on the sale order transaction. Further, the order processing unit 510 of the stock exchange 500 capable of market order, when the order information is order information corresponding to the market order, executes the market order based on the brand and the number of shares specified in the order information. Execute the transaction.

  Here, the ordering unit 280 includes information on whether the purchase order executed by the ordering processing unit 510 is executed or not executed among the information on the transaction result acquired by the transaction information acquiring unit 290. Obtained from the obtaining unit 290. Then, when the purchase order executed by the order processing unit 510 is uncommitted (step S220; NO), the ordering unit 280 further acquires an exchange rate from the exchange rate storage unit 240 (step S230). If the purchase order executed by the order processing unit 510 has been executed (step S220; YES), the process of this flow ends.

  On the other hand, when the exchange rate changes (step S240; YES), the ordering unit 280 calculates a new order price in the transaction currency corresponding to the order price in the settlement currency, and responds to the new order price. A value less than the step value may be corrected to the value of the step unit by rounding down, rounding up, or rounding specified by the user (step S250). In this case, the ordering unit 280 transmits ordering information including information indicating the new order price and order confirmation in the transaction currency to the transaction system 20 (step S200). If the exchange rate has not changed (step S240; NO), the ordering unit 280 executes the purchase order executed by the ordering processing unit 510 among the information on the transaction result acquired by the transaction information acquiring unit 290. Information regarding whether the transaction has been completed or not yet is acquired from the transaction information acquisition unit 290. Then, step S220 and subsequent steps are repeated again.

  In step S230, the ordering unit 280 acquires the exchange rate immediately after the exchange rate stored in the exchange rate storage unit 240 is updated with the exchange rate information input from the transaction information acquisition unit 290. On the condition that the exchange rate has changed, the order contents may be corrected based on the new order price in the transaction currency. Alternatively, the ordering unit 280 corrects the order contents based on the new order price in the transaction currency on condition that the exchange rate has changed by a predetermined fluctuation range or more. Also good. The fluctuation range may be specified by an input from the input unit 120 by the user.

  Further, the ordering unit 280 determines the order based on a new order price in the transaction currency in response to the change in the exchange rate or when the exchange rate changes by a predetermined fluctuation range. Information may be transmitted to the transaction system 20. Further, when the order information based on the exchange rate before the change has already been transmitted to the transaction system 20, the ordering unit 280 transmits information to the transaction system 20 to cancel the transmitted order information. You may do it.

  In addition, when the order information is, for example, order information corresponding to a program transaction such as a stop price, the ordering unit 280 acquires transaction information related to the brand specified in the order information from the transaction system 20, and When the condition is satisfied, order information corresponding to the purchase order (sale order) may be transmitted to the transaction system 20 based on the condition.

  FIG. 11 is a diagram illustrating an example of a balance evaluation screen. This balance evaluation screen is displayed when the user selects (clicks) “Balance inquiry” on the foreign stock main menu screen and transmits information indicating the selection from the user terminal 100 to the input reception unit 210. The information is displayed on the display unit 110 of the user terminal 100 by the output unit 230. In this example, the balance evaluation screen includes a brand display field 805a, a transaction market display field 805b, a possessed quantity display field 805c, a transaction currency display field 805d, an average acquisition unit price (transaction currency standard) display field 805e, and a market price (transaction currency standard). ) Display field 805f, acquisition exchange rate display field 805g, current exchange rate display field 805h, acquisition cost (settlement currency basis) display field 805i, valuation amount (settlement currency basis) display field 805j, and valuation profit / loss (settlement currency basis) A display column 805k is displayed.

It is calculated by multiplying the transaction unit price by the current exchange rate of the corresponding transaction currency displayed in the current exchange rate display field 805h.

  In the valuation profit / loss (settlement currency basis) display field 805k, the current valuation profit / loss for each stock held and investment trust held is displayed in the currency unit of the settlement currency. The valuation profit / loss displayed in the valuation profit / loss (settlement currency basis) display column 805k is, for example, the currency unit of the settlement currency for each share held and investment trust held in the valuation amount (settlement currency basis) display column 805j. Is calculated by subtracting the acquisition cost based on the currency unit of the settlement currency displayed in the acquisition cost (settlement currency basis) display field 805i from the current evaluation amount based on.

  In this example, the display content output unit 230 displays a balance evaluation screen in which the acquisition cost of the stock held and the investment trust held, the current valuation amount, and the valuation gain / loss are shown in Japanese yen, which is the user's settlement currency. It is displayed on the display unit 110 of the user terminal 100. Therefore, compared with the case where the balance evaluation screen showing the acquisition cost, current valuation value, and valuation gain / loss is displayed in the transaction currency, the user acquires the acquisition cost of the stocks and investment trusts held, and the current evaluation value. , And easier to grasp valuation gains and losses. In this example, a balance evaluation screen in which a list of stocks traded in different markets is displayed on the display unit 110 of the user terminal 100 is not limited thereto.
