Description

A method and apparatus on stock price list and profit calculation in cyber stock trading system}

The present invention relates to an apparatus and method for cyber trading service having a profit and loss analysis function. In particular, an investor can automatically know various calculation results without any form of calculation at each stage of a trading cycle, and an order input of a sell order is also provided. The present invention relates to a cyber trading service apparatus and method having a profit and loss analysis function for convenience.

In general, cyber trading using securities trading has been greatly increased due to the development of communication technology and computer programs. In Korea, more than 80% of the stocks are bought and sold on the same day, and cyber trading is expected to increase gradually in foreign countries.

The reason for the increase in cyber trading is because there are many advantages such as the ease of access by using a PC, providing various stock information, real-time understanding of the market price, and fast trading orders. In addition, the frequency of buying and selling of stocks has increased significantly compared to the past, which is attributable to the coordination of global stock markets, the increase in day trading, and the convenience of trading orders.

The stock trade consists of a cycle of stock price analysis → buy order → stock analysis → profit and loss analysis → sell order. Increasing the number of trades in stocks requires investors to cycle through the trading cycle frequently, calculating stock prices and profit and loss analysis at each stage, and entering trading orders frequently.

However, despite such changes in the stock environment, the existing cyber trading system provides little information to investors at each stage of stock price, profit and loss analysis, and sell orders, so that the investor roughly calculates and calculates trading orders accordingly. There is an uncomfortable problem. In other words, the investor manually calculates the price or profit or loss of the stock at each stage of the trading cycle, and the trading order is also done manually. As a result, investors suffer many inconveniences such as time consuming, mental energy consumption and inaccuracies in their calculations. In addition, in the prior art, the rapidity is not guaranteed in cyber trading which requires rapidity for the same reason.

Figure 31 shows an example of profit and loss calculations that the investor is currently performing by hand or by calculation. The investor calculates or calculates hundreds of thousands or millions of times daily for profit and loss as exemplified, and the investor's mental energy and time costs are enormous.

The conventional problems are listed at each stage of the stock price analysis, profit and loss analysis, and sell order cycle.

1) Stock price analysis stage-Investor does not provide price list. Existing cyber trading shows only 3 (1.5%) share price at the same time and 12 (6.5%) share price during opening. In addition, the rate of rise and fall is not provided at the same time, and only one rate of rise and fall is provided during the opening.

2) Profit and loss analysis stage-Investors do not provide profit and loss analysis at the price range they want to know. Traditional cyber trading provides less than 0.4% of total profit and loss data. Investors are directly conducting profit and loss analysis, the remaining 99%.

3) Sell order stage-Sell price and sell quantity input of sell order is an inaccurate and cumbersome way for investors to input manually by using mouse and keyboard. Opposite input of selling price and selling quantity, wrong number input (typing), dozens of eye movements and hand movements using mouse and keyboard, 10 seconds or more input time required, check whether input is correct after input, and gain and loss There are problems such as the unknown and the economic and mental costs of spending millions of orders per day. In addition, correct orders and cancel orders use the same input method.

4) Current Price Screen-There is no profit or loss information on the current price screen that investors see the most. The current bid price window is the key information for making a trading decision because the quantity of bids for each price is sold. However, share price information and profit and loss information are scattered because profit and loss analysis by price is not provided.

5) Existing stock price and profit analysis can only calculate the results at one price at a time. If the price changes, you have to recalculate from the beginning. The calculation of hundreds of stocks takes hours, so an investor cannot manually analyze the trend of profit or loss.

6) The calculation of profit and loss at one price cannot determine the trend of profit and loss by price range. Only one or two of the thousands of cells cannot report trends in overall profit or loss.

7) Calculation is possible only for one-dimensional calculation of one row concept of total stock price and profit and loss, and two-dimensional calculation of area concept is impossible. The calculation method is a number calculation method using an electronic calculator, a mouse and a keyboard.

8) It takes time to check account information. Executing the account information inquiry command generally takes time because it calculates the profit and loss from the securities company server, and the process is difficult and inconvenient to inquire repeatedly because it goes back and forth each time.

The technical problem of the present invention is to solve the disadvantages of the prior art, the cyber trading with a profit and loss analysis function to perform the stock price analysis, profit and loss analysis, selling order cycle process in only 1 to 3 seconds according to the investors' choice It is to provide a service apparatus and method.

It is in charge of regular printing.

3 shows the detailed configuration of the profit / loss list calculation program DB 170 of the profit / loss analysis system 100 of the first embodiment of the present invention. The profit and loss list calculation program DB 170 of the profit and loss analysis system 100 includes a stock price calculation program 170a, a fluctuation list calculation program 170b, a fluctuation list calculation program 170c, a profit and loss list calculation program 170d, and a profit rate. List calculation program 170e, gross selling price list calculation program 170f, gross selling rate list calculation program 170g, gross profit and loss list calculation program 170h, fee list calculation program 170i, fee rate list calculation program 170j The net profit and loss list calculation program 170k, the net profit and loss list calculation program 170l, and the overall profit and loss list calculation program 170m may be added, deleted, and changed as necessary.

The operation of each calculation program on the profit / loss list calculation program DB 170 is as follows.

The stock price calculation program 170a of the profit / loss list calculation program DB 170 is a program for calculating a stock price list in which the unit of quotation is applied from the upper limit price to the lower limit price using the reference price of the corresponding item. The operation calculates the upper and lower limits based on the reference price of the relevant item, which is an input item (1), and then calculates the stock price list by applying the quotations from the upper limit to the lower limit (2). (Lists of stocks with a base price of 10,000 won range from the upper limit of 11,500 won to the lower limit of 8,500 won, and the bid and ask price unit is 50 won units over 10,000 won, 10 won units below 10,000 won, and 180 shares). However, in countries where there is no upper or lower limit, the range set by the user (± 20.0%, + 30.0% to -5.0%, etc.) may be the upper and lower limit.

The fluctuation rate list calculation program 170b is a program for calculating the fluctuation rate for each stock price on the stock price list of the corresponding item. The rate of change is the rate at which each stock price rises and falls relative to the base price, and the rate of change = ((share price ÷ base price) -1) × 100. The fluctuation rate calculation calculates a stock price list using the reference price of the corresponding item as an input variable (1), and divides each stock price in the stock price list by the reference price (2). (The change rate of 11,500 won against the base price of 10,000 won is 15.0% and 8,500 is -15.0%.)

The fluctuation width list calculation program 170c is a program for calculating the fluctuation width for each stock price on the stock price list. The fluctuation means how much the price difference is for a particular stock compared to the standard price. Fluctuation = share price-reference price. The fluctuation calculation calculates a stock price list using the reference price of the corresponding item, which is an input variable (1), and minus the reference price from each stock price on the stock price list (2). (The price range of 11,500 shares is 1,500 won and 8,500 is -1,500, respectively.)

The profit and loss list calculation program 170d is a program for calculating the amount of profit and loss per share for each stock on the stock price list. Profit and loss means how much difference there is in a particular share price compared to the instrument price. Profit and loss) = share price-buy. There are two input variables for profit and loss calculations: the base price and the instrument. The profit-and-loss calculation calculates a stock price list using the base price (1), and minifies the purchase price from each stock price on the stock price list (2). (The stock price of W11,500 for each instrument is W1,000, and the loss of W8,500 is -2,000.)

The yield list calculation program 170e is a program that calculates the ratio of the selling unit price to the selling price for a specific stock on the stock price list. Yield refers to the percentage of profit and loss that a particular stock represents relative to the instrument price. Yield =

((Share price ÷ purchase number)-1 × 100. The input variable of the yield calculation has two standard prices and a means of selling. The yield calculation calculates a stock price list using the base price (1). Minus (2), and divide the result by the number of purchases (3) (the stock price of 11,000 is 10.0% for every 10,000 won, and 9,500 is -5.0%).

The total selling price list calculating program 170f is a program for calculating the selling amount for each stock price on the stock price list. The gross selling amount means the selling amount obtained when the holding quantity is sold at each stock price. Total selling amount = Stock price × quantity sold. There are two input variables for the gross selling amount calculation: the base price and the quantity. The calculation of the total selling price uses a base price to calculate a stock price list (1), and multiplies each stock price on the stock price list by the selling quantity (2). (If you sell 200 shares at the current price of 9,000 won, the total selling amount is 1.8 million won.)

The total selling rate list calculating program 170g is a program for calculating the ratio of the selling amount to the buying amount for each stock price on the stock price list. The gross selling rate is the ratio of the gross selling price to the gross selling price when the stock is sold at a particular price. Gross selling rate =

(Total selling amount ÷ total buying amount) × 100. There are three input variables for the gross selling rate calculation: reference price, quantity, and selling method. The gross selling rate calculation divides the stock price list calculation (1), the total selling amount calculation for each share price (2), the total buying amount calculation (3), and the total selling amount by the total buying amount using the reference price (4). . (If the quantity is 200 shares, the purchase price is 10,000 won, and the stock price is 10,800 won, the total selling rate is 108.0%.)

The gross profit and loss list calculation program 170h is a program for calculating the amount of loss or profit for each stock price on the current price list. Gross profit or loss is the gain or loss on sale of a particular stock. Gross profit = (share price-buy) × quantity, or profit or loss per share × quantity or total selling amount-total purchase amount. There are three input variables for gross profit and loss calculation: the base price, the quantity, and the means of sale. The gross profit and loss calculation is based on the calculation of the stock price list using the base price (1), the calculation of the total selling amount for each stock price (2), the calculation of the total buying amount (3), and the total purchase amount from the total selling amount (4). . (If the quantity is 100 shares, the purchase price is 10,000 won, and the stock price is 11,000 won, the total profit and loss is 100,000 won.)

The fee list calculation program 170i is a program that calculates a fee for each stock price on the stock price list. A commission is a fee payable in accordance with the amount of a sale if it is sold at a particular stock price. Commission = ((total amount of purchase × commission rate) + base fee) + (total amount of sale × (fee rate + government tax rate) + base fee). The input variables of the commission calculation are the base price, the quantity, the selling price, and the commission rate. The commission calculation adds the stock price list calculation (1) using the reference price, the selling price fee and the buying price fee for each stock price on the stock price list (2), and the selling price fee and the buying price fee (3). (If the commission rate is 0.3%, the basic fee is 1,000 won, the quantity is 100 shares, the number is 10,000 won, and the stock price is 11,000 won, the fee is 6,500 won)

The commission rate list calculation program 170j is a program that calculates a ratio of a fee to a transaction amount for each stock price on the stock price list. The commission rate refers to how much the commission is to be paid when sold for a particular stock. Fee = (Fee Rate × (Total Amount + Total Amount)) × 100. There are four input variables for commission rate calculation: base price, quantity, instrument price, and commission rate. The commission rate calculation consists of calculating the stock price list using the reference price (1), calculating the commission for each stock price on the stock price list (2), calculating the trading amount (3), and dividing the fee by the trading amount (4). The commission rate is 0.314% for 100%, 100 shares, 10,000 won and 11,000 won shares)

The net profit and loss list calculation program 170k is a program for calculating the net profit and loss for each stock price on the stock price list. Net profit or loss is the profit or loss remaining after subtracting a fee from the total profit or loss when the stock is sold at a particular price. Net Income = Total Amount-Total Amount-Commission, or Total Profit-Fee. The input and output variables of net profit and loss are the base price, the quantity, the selling price, and the commission rate. Net profit and loss calculation is the process of calculating the stock price list using the base price (1), calculating the total selling amount for each stock price (2), calculating the total purchase amount (3), calculating the commission (4), and minus the commission from the total profit or loss. It consists of (5). (If the quantity is 100 shares, the purchase price is 10,000 won, the stock price is 11,000 won, and the fee is 6,300 won, the net profit is 93,400 won (total profit and loss 100,000-fee 6,300).)

The net profit / loss ratio calculation program 170l is a program for calculating the ratio of net profit / loss to the purchase price for each stock price on the stock price list. The net profit or loss ratio refers to the ratio of net profit to purchase price remaining after deducting a fee from total profit or loss when it is sold to a particular stock price. Net profit / loss = ((total selling amount-total buying amount-commission) ÷ total buying amount) × 100. The input and output variables for net profit and loss calculations are the base price, the quantity, the selling price, and the commission rate. The net profit / loss ratio calculation is based on the calculation of the stock price list using the base price (1), the calculation of the total selling amount for each stock price (2), the calculation of the total purchase amount (3), the commission calculation (4), and the commission from the total profit or loss. It consists of calculating net profit and loss (5) and dividing net profit and loss by the total purchase amount (6). (If the quantity is 100 shares, the purchase price is 10,000 won, the present price is 11,000 won, the commission is 6,300 won and the net profit is 93,400, the net profit and loss ratio is 9.34%.)

The total profit and loss list calculation program 170m is a program for calculating the total profit and loss items for each stock price on the stock price list. Total profit and loss items are the percentages of fluctuation, fluctuation, profit and loss, profit rate, total selling amount, total selling rate, gross profit, commission, commission rate, net income, and net profit and loss. The input variables for the total profit / loss list calculation are four items: the base price, the quantity, the selling price, and the commission rate. The calculation is based on the stock price calculation (1), the fluctuation rate calculation (2), the fluctuation calculation (3), the profit and loss calculation (4), the yield calculation (5), the total selling amount calculation (6), and the total selling rate calculation (7). ), Gross profit and loss calculation (8), commission calculation (9), commission rate calculation (10), net profit and loss calculation (11), and net profit and loss ratio (12).

There are only four input variables required for the calculation of the profit / loss list calculation program: a reference price, a means, a quantity, and a commission rate, and all the calculation programs selectively execute all calculations using the four variables.

Next, when the price and price information (quotation price, selling quantity per bid and ask price) is input at regular intervals (3 to 5 seconds interval) from the profit and loss analysis system 100 (S45), the central processing unit 210 is the profit and loss analysis system 100 It is determined whether the offer price (selling price 5 and buying price 5) within the quoted offer range is different from the immediately entered bid price (S46). (For example, the bid and ask quantity information window 250c) The range of quotes in the table is raised from 20 price points of 7000, 7010, ..., 7080, 7090 to 7020, 7030, ..7100, 7110 by 20 won.)

As a result of the determination in step S46, since there is no change in the offer price range, the central processing unit 210 does not need to display the changed profit and loss data because the offer price does not change, so that only the offer price information window for the offer price and the offer price The display is displayed on 250c (S47).

As a result of the determination in step S46, if there is a change in the offer price range, the central processing unit 210 should display the profit and loss data for the newly added offer price. Therefore, the fluctuation of the quoted price and the number of bids for each quotation are displayed on the quotation information window 250c (S48) and the profit and loss list data stored in the main memory 230 is read through the operation (S44) (S49). Next, the central processing unit 210 displays the profit and loss data corresponding to the newly added quotations on the quotation window profit and loss list 250e (S50). Therefore, the user can automatically know his / her profit and loss value for the newly added quotation.

The above process (S48, S49, S50) automatically displays the profit and loss value corresponding to the price range when the price is fluctuating, so that the user can automatically identify the stock price information and profit and loss information simultaneously without any work. There is a characteristic. That is, since the price of a specific item is about 260, but only 10 prices are displayed in the price information window 250c, even if the price is changed, it means that the profit or loss value corresponding to the price is automatically displayed.

The following describes the selling order stage.

In order for a user to enter a sell order, the central processing unit 210 selects (double clicks) a specific price in the price information window 250c or grasps the profit or loss at a price of a price outside the offer price range and displays the price and price. In order to input the selling price, it is determined whether the stock price (row, row) of the profit / loss list window 250f is selected (double click) (S51).

As a result of determination, when the user selects a specific stock price, the central processing unit 210 automatically inputs the stock price selected by the user in the selling unit price input field 250h (S52), and at the same time, possesses quantity data of the corresponding item in the item information window 250b. Enter automatically into the selling quantity input field (250g) (S53). Accordingly, the selling unit price and the selling quantity required for the selling order are automatically input at the same time without a keyboard operation.

In addition, the central processing unit 210 highlights a row corresponding to the input selling price in the quotation information window 250c and the profit / loss list window 250g so that the user can visually distinguish the operation (S54).

On the other hand, the comprehensive calculation window 250j uses the number of purchases, the quantity, and the stock price selected by the user as the selling price, the quantity, the buying quantity, the selling price, the profit and loss, the yield, the total buying amount, the total selling amount, the total profit and loss (rate) The fee (rate) and net profit (rate) are shown (S55). Accordingly, the user can collect all the profit and loss data corresponding to the selling price of the selected quotation and at a glance, thereby making a more effective judgment.

When a sell order is input according to a user's selected quotation and the user selects an order transmission button according to the user's final confirmation and determination, the central processing unit 210 inputs an account number, a transaction password, an item code, and a selling price field for the selling order. The selling unit price in the column 250h and the selling quantity data in the selling quantity input field 250g are output from the profit and loss analysis system 100 (S56). Accordingly, the profit and loss analysis system 100 sends the selling order to the Securities Computerization Center 400 so as to conclude the sell order, and outputs the result of the trading execution to the client PC.

If the sell order sent by the user is not concluded or the order entered is corrected or canceled as follows.

After the sell order is input, the central processing unit 210 selects the cancel order button of the right mouse on the line corresponding to the highlighted selling price in the quotation information window 250c or the profit / loss list window 250g (S57). Cancel the sell order corresponding to the price (S58).

In addition, if the user drags a line corresponding to the highlighted selling price in the quotation information window 250c or the profit / loss list window 250g to another price or selects a new price (S59), the selling price of the selected price is sold. When the user automatically inputs the input field 250i and the user selects the correct order button, the seller corrects the newly selected price at the corrected unit price (S60).

By this process, the user can easily place an order such as buy or sell while viewing information related to profit and loss related to the investment, thereby having an advantageous environment for investment.

It is in charge of outputting to 100).

The present price screen 260 displays the stock price related information of the corresponding item under the control of the central processing unit 210, the quantity to be bought by the quotation and the quotation, and the profit and loss information by the quotation.

22 shows the structure of the profit and loss analysis program storage unit 240 according to the second embodiment of the present invention. The program of the profit and loss analysis program storage unit 240 is the same as the various calculation programs 170a to 170m of the profit and loss list calculation program DB 170 of the first embodiment.

The profit and loss analysis program storage unit 240 is composed of the following 13 calculation programs. That is, the stock price calculation program 240a, the fluctuation list calculation program 240b, the fluctuation list calculation program 240c, the profit and loss list calculation program 240d, the profit rate list calculation program 240e, the total selling price list calculation program ( 240f), gross selling rate list calculating program 240g, gross profit list calculating program 240h, commission list calculating program 240i, commission rate list calculating program 240j, net profit and loss list calculating program 240k, net profit and loss list calculating program 240l, the total profit and loss list calculation program 240m.

The operation of each calculation program on the profit / loss list calculation program DB 170 is the same as in the first embodiment. Therefore, the description of the operation of each program is omitted.

The profit / loss list calculation process of the cyber trading service apparatus according to the second embodiment having the above configuration will be described below.

The client PC 200 proceeds to the profit and loss analysis system 100 of each securities company through the network communication network 300 (T1).

The client PC 200 receives the user login screen data and displays it on the main screen (T2).

The client PC 200 outputs the login data of the ID and password entered by each user to the profit and loss analysis system 100, and the profit and loss analysis system 100 displays the main screen of the latest cyber trading program when the user is a regular user. Output to PC (T3).

Thereafter, the central processing unit 210 of the client PC 200 stores the newly downloaded profit and loss analysis program in the profit and loss analysis program storage unit 240 and displays the main screen (T4).

When the user selects the seller culture plane 250 on the client PC 200, the central processing unit 210 displays the seller culture plane 250 (T5).

When the user selects the holding item confirmation button 250a on the selling stock culture surface 250, the central processing unit 210 outputs the holding item confirmation signal to the profit and loss analysis system 100, and holds the amount of the profit and loss analysis system 100. DB 140, the selling means receives the holding item information from the DB 150, the stock price information DB 190 and displays data (item name, reference price, selling price, holding quantity) in the holding item information window 250b (T6). ).

When the user selects a specific item among the items displayed in the item holding information window 250b, the central processing unit 210 periodically checks the price information (quotation price of the item for sale and the quantity of the bid and ask price) from the profit and loss analysis system 100. Is received and displayed on the quotation information window 250c (T7).

The above processes T1 to T7 are well known in the art, and detailed descriptions are omitted.

Through the processes T1 to T7, the cyber trading system of the client PC 200 secures a profit / loss list calculation program (including a commission rate) and input variables (standard price, number of purchases, and quantity held) for calculating various profit and loss lists. .

The following describes a process of calculating various profit and loss lists on the cyber trading system of the client PC 200.

If the user selects the drop-down button 250d in order to know the profit / loss list of the corresponding item in a state in which the quotation information is regularly displayed in the quotation information window 250c of step T7 (T8), the central processing unit 210 ) Displays the profit / loss list window 250e (T9).

When the user selects a specific item from the profit and loss items listed in the profit and loss list window 250e (T10), the central processing unit 210 loads the corresponding profit and loss calculation program from the cyber trading program storage unit 240 (T11). Then, the input variable data (standard price, selling price, holding quantity) of the corresponding item in the holding item information window 250b is loaded (T12).

Now, the central processing unit 210 executes the calculation using the profit / loss list calculation program and the input variable data (the reference price, the selling price, and the retained quantity) input through the processes T11 and T12 (T13).

The calculation is performed in the same manner as the calculation performed by the profit and loss list calculating unit 180 of the profit and loss analysis system 100 as described in the first embodiment (the calculation routines for the profit and loss items are S12, S14, and S16 of the first embodiment). , S18, S20, S22, S24, S26, S28, S30, S32, S34, so they are omitted here).

The displaying of the calculated profit / loss list data proceeds in the same manner as in the first embodiment.

When the calculation is completed, the central processing unit 210 displays the profit and loss data corresponding to the current bid price currently displayed in the bid price information window 250c in the bid price window profit list 250e (T14) and the profit list window 250f. Display all profit and loss data (T15).

In addition, the central processing unit 210 transmits the calculated profit / loss list data to the main memory 230 to temporarily store (T16).

Next, when the price and price information (quotation price, selling quantity per bid and ask price) is input at regular intervals (3 to 5 seconds interval) from the profit and loss analysis system 100 (T17), the central processing unit 210 is the profit and loss analysis system 100 It is determined whether there is a difference in the offer price (selling price 5, buying number 5) from the quoted price entered into the previous quoted price (T18).

As a result of the determination in step (T18), if there is no change in the offer price range, the central processing unit 210 does not need to display the changed profit and loss data because the offer price does not change, so that only the offer price window for the offer price and ask price Displayed at 250c (T19).

As a result of the determination in step T18, if there is a change in the offer price range, the central processing unit 210 should display the profit and loss data for the newly added offer price. Therefore, the fluctuations in the quoted price and the number of bids for each quote are displayed on the quote price information window 250c (T20), and at the same time, the profit and loss list data stored in the main memory 230 is read through step T16 (T21).

Next, the central processing unit 210 displays the profit and loss data corresponding to the newly added quotations on the quotation window profit and loss list 250e (T22).

The following is the process of selling orders, correction orders, and cancellation orders. Sell-related orders (sell orders, corrective orders, cancel orders) proceed in the same manner as the above steps S51 to S60 of the first embodiment. (T23-T32). (The detailed description is therefore the same as that of the first embodiment, so the description is omitted here).

For reference, some data and calculated results applied to the embodiment of the present invention will be described.

24A through 24E are examples of the overall profit and loss list calculated by the cyber trading system 200. The calculated items consist of 12 of all stock price items (3 items) and all profit and loss items (9 items). The number of stocks is 260, so the total number of data is 3,120 (12 columns × 260 rows). The time required for calculation on the client PC according to the second embodiment is about 0.1 second. The data may be edited and displayed in various ways according to screen characteristics (present price, seller culture page, etc.) or the user's request. According to the user's request, only a specific column or a specific area of data can be displayed, which has the same meaning as making various garments using fabric fabric.

25A and 25B illustrate an example in which the account information, the offer price information, and the profit and loss analysis information are collectively displayed as the seller culture surface 250 according to the present invention. For example, after investing 1,850 shares of Kumkang Securities for W8,580, the investor's profit and loss, which changes by price list and price range, can be immediately identified through the stock price window 250c and the profit list window 250g.

After investor comprehensively judges the progress of stock price and profit and loss, he decides to sell and double clicks 8,730 won in profit and loss window (250g) to sell stock. Each is entered and a sell order is sent.

In this case, the profit and loss list window 250g highlights the buy price (W8,580) and the sell price (W8,730), thereby visually distinguishing the difference between the buy and sell prices. In the total calculation window 250j, when the selling price is input or changed, various profit and loss result values are collectively displayed to assist the investor in determining the profit and loss items.

On the other hand, the profit and loss column (total profit and loss, commission, etc.) of the profit and loss list window 250g can be increased or decreased by editing the investor's choice.

In the correct order, when the investor double-clicks the correction price of 8,700 won or drags the highlighted selling price of 8,730 won to the correction price of 8,700 won, the correction order is executed as the selling price 250i is input.

For intake orders, select the cancel command with the right mouse button on the row where the 8,730 won is highlighted.

FIG. 26 shows an example of the drop-down button 250d and the quotation window profit and loss list 250f attached to the screen 260. The current screen is the screen that provides the most information about the stock, and therefore is the screen that investors see the most. However, the existing current price screen has only stock price information and no profit or loss information. Therefore, the investor must alternately display the current price screen and the account information screen to identify the profit and loss. In the case of profit and loss inquiry, there is a problem that the server of the securities company provides only two gross profits and profits based on the current price and takes time for communication and operation.

The improved current price screen according to the present invention displays a combination of stock price information and profit and loss information. The three types of information can be gathered in one place for comprehensive judgment. As a result, investors can judge the stock price and profit at the same time in real time, and experience synergies combining core information. As a result, they can maximize their profits by realizing appropriate profits or by making bold stoppages.

FIG. 27 shows an example of the profit / loss list window 250e displayed according to the selection of the drop-down button 250d. When an investor selects a drop-down button to select a profit or loss item of interest, a list of profit and loss items such as the rate of change, the amount of change and the total profit or loss are listed. Selecting total profit and loss gives you all the items of stock price and profit and loss, and provides you with all the gains and losses at all price points, such as Figures 24A-25D.

Fig. 28 summarizes the input variables and expressions of the profit / loss analysis programs 170a to 170m (240a to 240m). The principle of the present invention is that all the stock prices (quotation prices, fluctuation rates, fluctuation widths) can be calculated as long as there is only a reference price, and all profits and losses can be calculated using three input variables, the purchase price, the purchase quantity, and the commission rate. The base price is basically used for all calculations, and the profit and loss analysis shows that the instrument price and quantity are basically required.

29 is a comparison between the existing sell order method and the improved sell order according to the present invention. Improvements made by the present invention include the convenience that the investor automatically enters the selling price and quantity at the same time with a single click of the mouse. No input check required, minimizing eye and hand gestures, and minimal keyboard operation and time due to the absence of a keyboard.

An investor can complete an order by analyzing the stock price and profit and loss on the profit and loss list and selecting the desired selling price once with the mouse. Correct orders and cancel orders are made with a single mouse movement.

30 is a comparison between the existing cyber trading method and the profit and loss analysis system according to the present invention. The present invention is to improve the profit and loss analysis and sell order process performed by investors at each stage of the stock purchase (purchase stage) → stock analysis stage → profit and loss analysis stage → sell decision → sell order → end cycle. In other words, all prices and all gains and losses are provided to the investor quickly and accurately, so the investor is completely freed from calculations and inputs. Investors can also cycle through the entire trading cycle in seconds.

As described above, the cyber trading service apparatus and method according to an embodiment of the present invention has the following effects.

1) Investors can see all the stocks (shares, futures, and options) in a tabular form with a list of all the stock prices, fluctuation rates and fluctuations that can occur on the day, with a single click of the mouse. have.

2) Automatic Order-Investor can enter the Selling Price and Selling Quantity at the same time with just one click of the Selling Order. When an investor selects a specific stock in the profit / loss list, both the selling price and the selling quantity are automatically entered at the same time.

3) Automatic Correction, Cancel Order-Investors can execute Sell Clear Order or Cancel Order with a single click of the mouse.

4) Order Improvement-Sell orders are executed in just one second over a 10 second timescale. Unnecessary losses are avoided because there is no opposite input of selling price and selling quantity. There is no typo in the selling price and selling quantity input data. There is no need for more than 10 keyboard inputs required for price and quantity input. The eyes had to alternate between the monitor and the keyboard four or more times, but only the monitor was stared. There is no need for the investor to finalize that the quantity and unit price have been entered correctly before the order is sent. Investors do not need to analyze profit or loss after order entry. You do not have to use to alternate between keyboard and mouse to enter numbers.

5) Synergy effect-Investor can grasp the three most important information at the same time from the price information window, the price of the stock price, the quantity to buy and the price of each price, and the profit and loss analysis by the price. .

6) Two-dimensional calculation-In the past, only the profit and loss at one price (Cell unit) based on the present price was available. However, according to the present invention, all data of the two-dimensional concept (Area) at all price points can be calculated at one time. Done

7) Aggregated Data Representation-Since the stock price and profit and loss analysis data are expressed in tabular form, investors can gather a lot of data and understand them at a glance. Simultaneously visually compare and analyze the stock price, up and down list, and list of up and down width, allowing investors to make comprehensive price judgments based on synergies. Previously, only two gross profits and returns were known, but now you can analyze profit and loss on all nine broader profit and loss items.

8) Time cost savings-The mental energy spent on investor stock price and profit and loss analysis is saved. The time spent on stock price calculation, profit and loss analysis, and selling orders was saved, which saved more than 200 billion won in economic time.

9) Support for Stop Loss Decisions-Investors can make comprehensive decisions about the progress of profits and losses by price range, enabling them to make more effective trade decisions. In the case of losses, investors can visually see the increasing trend of losses, which are deepened by price range, allowing investors to minimize losses through more aggressive stop loss.

10) Investors can check the current price screen and account information screen in order to know the stock price and profit and loss at the same time without having to look up the screen alternately. Investors no longer need to view the account information screen for profit and loss analysis.

11) Note papers, writing instruments, and electronic calculators are no longer needed in front of investors' monitors. Investors can more effectively analyze stock prices and profit and loss by printing profit and loss list data in advance and placing them in front of the monitor.

12) If you use the manual calculator, you can analyze the profit and loss at the long-term price range outside of the fluctuation range of today's price (if the current price is 1,000 won, enter the future price as 2,500 won).

13) No selling input is required for profit and loss analysis. Each share price on the share price list is assumed to be a sell and has the same calculation result as if each share was entered as sell.

14) If there is only a base price, a list of fluctuation rates and fluctuations by share price is calculated along with all the stock prices from the upper limit to the lower limit. All price-based profit and loss analyzes are calculated using only four variables: the base price, the number of purchases, the quantity of purchases, and the commission rate.

15) Identifying break-even points-Day traders can visually identify break-even points on the seller's culture and current price screens, thereby maximizing their profits.

16) Futures and options have much greater fluctuation rates and trading gains and losses than stocks, which necessitates more stock price and profit analysis.

17) Securities firms will provide better quality services to their customers. In particular, securities staff and securities experts can provide customers with faster and more diverse services, which can increase mutual satisfaction. In addition, investors in the branches of securities firms can print out the stock price and profit and loss list in advance without having to go back and forth to the terminal to check the balance.

Although the present invention described above has been described with reference to a preferred embodiment, those skilled in the art as described in the claims below and the list of all stock prices existing in the stock market with a single click of the investor as described in the claims Various modifications and changes of the present invention can be made without departing from the spirit and scope of knowing various gains and losses per share price within one second and orders are automatically executed.
