Online trading system for multiple stocks through the same screen {Home trading system for decision of trading volume of plural stocks using a one window}

The present invention relates to an online stock trading system of multiple stocks through the same screen.

More specifically, when an online securities trading user specifies a plurality of securities and total trading amounts to be traded through one batch screen, and enters a trading ratio for each item, the number of securities that can be traded at the securities company that provides the online securities trading service. And automatically calculate the transaction amount and display the result on one batch trading screen, and the online securities trading user who checks the result displayed on one batch trading screen can perform the securities trading promptly according to the result. It relates to an online stock trading system of multiple stocks through the same screen.

In general, the Internet is an open network that can be used freely by applying a common protocol called TCP / IP (Transmission Control Protocol / Internet Protocol) to the other computer that anyone wants to access anywhere in the world. In addition to the delivery, as well as the development of compression technology and the delivery of multimedia information, various services such as e-mail, file transfer, and the World Wide Web (WWW) can be used.

As the use of the Internet is rapidly increasing in Korea and around the world, it is rapidly increasing in importance as a strategic tool for improving efficiency and productivity in all parts of the existing industry, and new business opportunities are continuously created through the Internet. The number of service providers on the Internet is increasing.

That is, in recent years, as part of the business through the Internet, various contents such as internet advertising, internet broadcasting, online games, internet newspapers / magazines, search services, portal services, electronic commerce, etc. are provided. Sites are growing rapidly.

Recently, the sites of each securities company that provides an online securities trading system (or home trading system) to buy and sell securities on the network, along with the explosive interest of various computer users. Increasingly, securities companies are working hard to attract computer users who want to use the online securities trading system.

In other words, even if you do not go directly to the store or use a telephone when you are trading securities, securities investors are exploding due to the advantages that can be used anywhere where a computer environment is established and the savings of various fees incurred in stock trading. It is increasing.

When computer users using the online securities trading system want to buy securities, they first look up the available amount of money in their securities account, and then compare the current price of the item they want to buy with the available amount. The total amount was calculated, and the purchase quantity corresponding to the total amount was determined to fulfill the order.

And, even if you want to sell the securities you hold for withdrawal or repurchase of a certain amount, if you want to sell a certain portion of the items you own to make the necessary amount, after the conclusion of all sold items is concluded Through the confirmation screen, the total selling amount could be confirmed at once.

In addition, conventionally, a number of securities accounts held by online securities trading users are provided to enable the sale and sale of specific securities, and the securities securities are sold.

However, in the conventional online securities trading system as described above, the method of determining the buy and sell amount used by the securities trading users was not very inconvenient to use when dealing with a single item without any difficulty. If the number of stocks were not one but several, they had to be written down on paper, and there was a risk of errors in calculation, as well as ordering for each stock separately. In the case of inconvenience, you need to modify the order again.

In case of buying or selling a number of stocks, if a certain ratio is used to buy and sell, the calculation method is very complicated, and it is not possible to respond quickly to changing stock prices. Investors, securities brokers, and dealers who are interested in stocks are always exposed to the risk of these mistakes.

In addition, the conventional method of buying and selling securities is a method of directly inputting the number of buys and sells for each item, rather than selecting and entering various quantities that the user can buy and sell. It was inconvenient to check the total transaction amount and the expected balance and commission at the time of entering by entering the quantity to buy and sell only after connecting.

An object of the present invention is to provide an online securities trading service when an online securities trading user inputs a plurality of securities, total trading amounts, and trading ratios for each item so as to solve the above problems. The securities firm automatically calculates the quantity and transaction amount that can be traded for each item, and then displays the calculation results on one batch screen so that online stock trading users can immediately check the results. To provide an online securities trading system.

Another object of the present invention is to enable users of online securities trading to check the quantity and the amount of trading available for a plurality of items displayed through one batch trading screen, and to adjust the trading quantity or trading ratio for each item on the corresponding screen. It is to provide a multi-line online securities trading system through the same screen that allows you to carry out a bulk trading order according to the trading quantity or the trading ratio determined in.

Perform a communications connection.

Next, an embodiment of the online stock trading method of multiple items through the same screen according to the present invention configured as described above will be described in detail with reference to FIGS. 3 to 7.

3 to 7 are flowcharts showing in detail the operation of the online stock trading method of a plurality of items through the same screen according to the present invention.

First, the server computer 30 provides a batch trading screen to the corresponding user computer 20 according to the selection of a menu of the online stock trading user who has made a communication connection through the network communication network 10, and at the same time, the user's stock account. The information is extracted from the database and output to the batch trading screen (S10).

In detail, when an online securities transaction user performs a communication connection to the server computer 30 through the network communication network 10 (S11), predetermined user authentication for the user computer 20 is performed. Outputs form data.

Then, it is determined whether the user inputs the login data of the ID and password according to the predetermined form data output from the server computer 30 (S12).

Then, after performing the user authentication according to the login data of the ID and password input by the user, the server computer 30 determines whether the user selects a batch trading menu among a plurality of menus provided by the server computer 30. (S13).

As a result of the determination, when the user selects the batch sale menu, the server computer 30 provides one batch sale screen to the user computer 20 (S14), and extracts the account information held by the user from the database. Subsequently (S15), the securities account information of the user extracted from the database is output on the batch trading screen of the user computer 20 (S16).

In this case, when each user confirms the purchase amount through the securities account information provided from the server computer 30 to the user computer 30, the corresponding user uses a predetermined amount unit (for example, 10 10,000 won, 500,000 won, 1 million won, 5 million won, 100 million won).

On the other hand, if the user selects a different menu such as buy, sell, inquiry, etc. without selecting the batch selling menu as a result of the above-described determination (S13), the server computer 30 provides a service according to the menu selected by the user. (S17).

As described above, the server computer 30 provides the batch trading screen to the corresponding user computer 20 and outputs the stock account information of the corresponding user according to the user's selection of the collective selling menu through the above-described process (S10). Selection data of any one of the batch buying / selling from the computer 20 and a plurality of securities items to be bought and sold, the total buy / sell amount, and the buy / sell ratio for each item Receives data (S20).

In detail, the server computer 30 determines whether the user who checks the securities account information he / she holds on the batch selling screen selects either the collective buying or the collective selling (S21).

When the user selects the collective purchase, the server computer 30 determines whether the corresponding user inputs the number of stock items and the total purchase amount to purchase on the collective purchase screen (S22).

At this time, when the user inputs the total purchase amount through the above-described step (S22), the server computer 30 allows the user to directly enter the amount, or as described above in the user's window screen The up and down bar allows the server computer 30 to select any one of the amount of money provided by equally dividing it by a certain amount according to the user's stock account holding amount.

As a result of the determination in step S22 described above, when the user inputs the number of stock items to be bought and the total purchase amount on the batch purchase screen, the server computer 30 selects the securities selected by the user to buy one batch trading screen. A data input window for dividing according to the number of items and selecting a plurality of securities items to be bought on each split screen and a data input window for inputting purchase ratio data for each item is provided (S23).

Thereafter, the server computer 30 determines whether the corresponding user inputs securities item selection data and purchase ratio data for each item through the data input window on each split screen (S24).

As a result of the determination, when the user inputs a plurality of stock items, total purchase amount, and purchase ratio data for each item that the user inputs for the data calculation request for the collective purchase, the corresponding data is output to the server computer 30 ( S25).

On the other hand, when the user selects the collective selling as a result of the determination in step S21 described above, the server computer 30 extracts a plurality of securities data held by the user from the database and provides the data to the user computer 20. In operation S26, the user selects a plurality of securities items to be sold from among a plurality of securities items held by the user provided by the server computer 30, and determines whether to input the total selling amount (S27).

As a result of the determination, when the user inputs the number of securities items to be sold and the total selling amount on the batch selling screen, the server computer 30 divides one batch selling screen according to the number of securities items selected by the user to sell. In addition, a data input window for selecting a plurality of securities items to be sold on each split screen and a data input window for inputting selling ratio data for each item are provided (S28).

Thereafter, the server computer 30 determines whether the corresponding user inputs the securities item selection data and the selling ratio data for each item through the data input window on each split screen (S29).

As a result of the determination in step S29, when the user inputs a plurality of securities, total selling amount, and selling ratio data for each item to sell for the data operation request for collective selling, in step S25, The data is output to the server computer 30 as follows.

Through the above-described process (S20), a plurality of stock items, total buy / sell amount, and buy / sell ratio data for each item that a plurality of users input for a data operation request for collective sale are input. After receiving, the server computer 30 calculates the available quantity and transaction amount data for each item of the user based on the plurality of securities items, the total sale amount, and the trading ratio data for each item inputted by the user. The output to the user computer 20 (S30).

In detail, the server computer 30 includes a plurality of securities stocks, a total sales price, and a buy / sell ratio data for each stock that a specific user inputs for a data purchase request for a collective purchase or a collective sale. It is determined whether the input via the (S31).

As a result of the determination, when a plurality of securities items, total trading amount, and buy / sell ratio data for each item are inputted, the server computer 30 provides a plurality of securities items, total selling amount, and buy / sell ratio data for each item inputted by the corresponding user. Based on the current price of the securities trading in the securities trading market based on the current price and the amount of trading available for each item that can be traded and the transaction amount (S32).

For example, if a user inputs a purchase rate for each of the four securities items in order to order the four securities items collectively, the server computer 30 prepares for the total purchase amount according to the purchase rates for the four securities items. The purchase amount for each securities item is calculated, and the available order amount corresponding to the purchase amount determined for each securities item is calculated and provided to the user.

Then, the calculated quantity for sale and the transaction amount data for each item are output on the collective sale screen of the corresponding user computer 20 (S33).

In this case, in the above-described step (S32), when calculating the available purchase amount for a plurality of securities items based on the total purchase amount and the purchase ratio input by the user based on the current price of the securities trading in the securities trading market, the server computer (30) is calculated by ignoring less than the minimum unit of purchase order among the available quantity of each securities. In other words, assuming that the minimum purchase order unit is 10, if the available purchase amount of a specific securities item is 27.34 calculated according to the desired purchase rate, the server computer 30 determines that the available buying amount of the specific securities item is 20. Assuming that the minimum unit of purchase order is 1 and the buyable quantity of a specific securities item calculated according to the desired purchase rate is 27.34, the server computer 30 calculates the available quantity of a specific securities item. It is determined by 27 and provided to the user. This is because, when an order is placed in a quantity higher than the purchase ratio set by the user, if the purchase amount held by the user is insufficient, the securities item cannot be bought. Accordingly, the result of the calculation performed by the server computer 30 based on the data input for the batch purchase by the specific user is finally calculated with an amount less than the total purchase amount initially input by the user.

In addition, in the above-described step (S32), when calculating the available for sale for each of a plurality of securities items based on the total selling amount and the selling ratio entered by the user based on the current price of the securities in the securities trading market, the server computer (30) is calculated by rounding up the minimum selling order among the available quantities for each securities item. In other words, assuming that the minimum order for a sell order is 10, if the available quantity of the specific securities calculated by the user's desired selling rate is 27.34, the server computer 30 determines that the available quantity of the specific securities is 30. Assuming that the minimum order of selling orders is 1, if the available-for-sale quantity of a specific securities item calculated by the user's desired selling rate is 27.34, the server computer 30 sells the available-for-sale quantity of a specific securities item. Is determined to be 28 and provided to the user. This is because, when an order is placed in a quantity lower than the selling rate set by the user, if the selling is made in that quantity, the user cannot withdraw the required amount. Accordingly, the calculation result performed by the server computer 30 based on the data inputted by the specific user for the collective selling is finally calculated as an amount greater than the total selling amount initially input by the user.

Finally, the server computer 30 calculates the quantity available for trading and the transaction amount data for each item according to the user's collective purchase or collective selling calculation request through the above-described process (S30), and then provides the result. When the bulk purchase order of the corresponding user who checks the available quantity and transaction amount data for each item is requested, the collective sale of a plurality of securities items requested by the user is performed through the stock market (S40).

In detail, the user who has requested a data operation for batch trading checks the available quantity and transaction value data of each securities item output from the server computer 30 through each split screen of one batch trading screen (S41). ).

Thereafter, the server computer 30 determines whether the corresponding user requests the bulk sales order according to the operation result data (S42).

As a result of the determination, when the collective sale order is requested by the corresponding user, the server computer 30 collectively sells a plurality of securities through the securities trading market according to the calculation result provided to the corresponding user through the above-described process (S30). Proceed to step (S43).

In addition, the server computer 30 outputs the result data concluded in accordance with the performance of the collective sale through the stock trading market to the corresponding user computer 20 (S44), and the collective sale result data can be traded for each securities item provided to the corresponding user. Along with the quantity and transaction value data is stored in the database (S45).

On the other hand, the user who checks the available and available trading amount and transaction value data for each securities item output from the server computer 30 through the above-described step (S41), the user can buy the available or available trading amount for each item provided by the server computer 30 It is possible to arbitrarily change and request a batch trading order. When the batch trading screen displaying the operation result is terminated, a menu other than the batch trading menu can be used.

As described above, according to the online stock trading system of a plurality of stocks through the same screen of the present invention, when online stock trading users trade a plurality of stock stocks, one batch trading screen is not required for each stock. Through the user's desired trading amount and trading ratio, online stock trading users who trade multiple securities can easily check the available quantity and trading amount of multiple securities and perform securities trading at once. This makes it easy to calculate the composition of the desired portfolio, as well as preventing calculation and order errors.

In addition, users can greatly reduce the time that needs to be calculated by hand, and because it is possible to perform the order of the desired item at the same time without having to order each item at the same time, it is possible to make a quick order and shorten the decision time, This has the benefit of helping a lot of scalers or day-trader.

In addition, the fund manager in charge of the portfolio of the fund is advantageous in organizing and releasing the portfolio allocation, so that it is easy to organize the assets in the way you want, and to reduce the fund size according to the customer's repurchase request amount. And the ability to fulfill orders while maintaining their portfolio composition in expansion.

In addition, in the case of derivatives, in addition to the general securities, the same order can be executed, thus providing the effect of spot investments linked to derivatives.

Herein, while the present invention has been described with reference to the preferred embodiments, those skilled in the art will variously modify the present invention without departing from the spirit and scope of the invention as set forth in the claims below. And can be changed.
