Description

An Apparatus and Method on Profit Analysis Services of Cyber Stock Trading System}

In general, cyber trading using securities trading has been greatly increased due to the development of communication technology and computer programs. The reason for the increase in cyber trading is because there are many advantages such as ease of access by using a PC, providing various stock information (graphs), real-time tracking of quotes, and simple trading orders.

Equity investment consists of a cycle of stock price analysis → buy order → stock price analysis → profit and loss analysis → sell order → withdrawal of investment income.

Analyzing the above process, it can be seen that stock investment is divided into the scope of stock price analysis and profit and loss analysis. First, the stock price area is an objective area that represents only stock price information, and the profit and loss area is an area that shows information about the individual's personal profit and loss after the stock purchase. In addition, the share price area becomes the input value, the share price change is the intermediate processing, and the profit and loss area corresponds to the output value. Thus, the investor always pays most attention to the output, which is the conclusion of stock investment.

Meanwhile, when looking at the recent cyber trading system, the stock price area is greatly developing, while the profit area that investors are most interested in remains at the basic level. The stock price information (Input) provides a variety of information in real time for a number of price ranges (stock price) on the current price screen, the item of interest screen, various stock graphs.

On the other hand, the profit and loss information (Output) is provided on the account information screen with only one gross profit or rate of return based on the current price of the item. Thus, although the stock price is offered in hundreds of stocks, only one price is provided.

However, a stock investor wants to know the gain or loss of a future share price rather than the gain or loss at present. In other words, many investors (millions or tens of millions of stocks) are interested in gains and losses from changes in stock prices, but do not know them automatically. As a result, investors personally calculate future profits by hand, but the cyber trading system does not recognize such inconveniences and problems. In other words, the profit and loss area is the most important part for investors but is still unexplored.

In order to solve this problem, the present invention is composed of the contents to provide in real time on the cyber trading system various profits and losses for each stock corresponding to all the stock prices on the graph. Therefore, the investor no longer needs to make any profit or loss calculations. Since the stock price and profit and loss are always provided simultaneously in real time, the stock price and profit and loss areas are balanced. As a result, stock investors will be able to receive faster, more accurate and convenient profit and loss analysis services, and will be able to maximize their profits by making various profit analysis and making appropriate selling decisions.

The scope of the present invention is intended for the stock price graph on the cyber trading system, and automatically calculates the price and profit (gross profit and loss, commission (rate), profit and loss (rate), return, total selling amount, total selling rate) on the stock graph Calculate and provide it to the investor in real time.

The analysis of the conventional problems of the cyber trading system related to the profit and loss area is as follows.

1) The stock price range is 100% and the profit and loss area is 0.1%. On the stock graph, there is only stock price information and no profit or loss information.

2) Long-term gains and losses are unknown. -We do not provide any changes in profit or loss in the long run. The profit or loss value of the stock price of W23,500 ~ 25,000 for the stock price of W16,350 is unknown.

3) Too little profit or loss information. -Profit and loss information is provided only one value (total profit and loss based on the current price) on the account information inquiry screen only.

4) The stock price and profit and loss information are divided. -Since the stock price information screen (present price, stock price graph) and the profit and loss information screen (account information inquiry screen) are separated, investors have to look up the screen alternately.

5) On the stock graph, we cannot know the margins for the Stop Loss (-10.0% yield, the Stop Loss Price Range, etc.), the Profit Limit (Return + 25.0%, Hope Sell, etc.) and the Buy Price Range.

6) The company does not recognize the importance of profit and loss areas. -For investors, the most important thing is not recognizing the price / loss of each stock price.

7) When investor analyzes stock price and profit by hand, it can calculate the result value at one price at a time and it takes several tens of seconds. 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.

8) The calculation of profit and loss at one price cannot be used to comprehensively determine the trend of profit and loss by price range. One or two profit and loss calculations out of hundreds of shares do not capture the trend of overall profit or loss.

9) Calculation is possible only for one-dimensional calculation of one row concept of total stock price and profit and loss, and not two-dimensional calculation of area concept. The calculation method is a number calculation method using an electronic calculator, a mouse and a keyboard.

10) It takes time to retrieve 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.

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 / loss list calculation program DB 170 of the profit / loss analysis system 100 includes a profit / loss list calculation program 170a, a profit rate list calculation program 170b, a total selling amount list calculation program 170c, and a total selling rate list calculation program 170d. ), A total profit and loss list calculation program 170e, a net profit and loss list calculation program 170f, a net profit and loss list calculation program 170g, and can 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 profit and loss list calculation program 170a 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 = Stock Price-Buy. The input and output variables for the profit and loss calculation are the maximum minimum value and two selling methods. The profit and loss calculation calculates the stock price list by calculating the stock price list applying the unit of quotation from the maximum (scale) value to the minimum (scale) value among the stock price graphs in the corresponding item (1) (maximum value 40,000 won, minimum value 16,000). The stock price list of the pie graph is 40000, 39950, 39900, ... 16100, 16050, 16,000 won), and the number of purchases is negative from each stock price on the stock price list (2).

The yield list calculation program 170b 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 / buy) -1) * 100. The input variable for the rate of return calculation is the maximum minimum value and two means of sale. The yield calculation calculates a stock price list using the maximum and minimum values of the stock price graph (1), minus the number of copies from each stock price on the stock price list (2), and divides the result by the number of copies (3).

The total selling price list calculating program 170c 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 = Share Price * Sell (holding) Quantity. The input variables for the total selling amount calculation are two values, the maximum minimum value and the quantity. Computation of the total selling amount calculates a stock price list using the maximum value and the minimum value (1), and multiplies each stock price on the stock price list by the selling quantity (2).

The total selling rate list calculating program 170d is a program for calculating the ratio of the selling amount to the buying amount for each stock price on the stock price list. Gross selling ratio refers to the ratio of the total selling amount to the total buying amount when the stock is sold to a particular stock price. Total Selling Rate = (Total Selling Amount / Total Buying Amount) * 100. The input variables for the gross selling rate calculation are three minimum values, a quantity, and a selling method. The total selling rate calculation divides the stock price list calculation using the maximum value and the minimum value (1), calculates the total selling amount for each share price (2), calculates the total buying amount (3), and the total selling amount by the total buying amount ( 4).

The total profit and loss list calculation program 170e is a program for calculating the amount of loss or profit for each stock price on the stock 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. The input and output variables for gross profit and loss are three minimum values, a quantity, and a means of sale. The gross profit and loss calculation minus the total purchase amount from the stock price list using the maximum minimum value (1), the total selling amount calculation for each share price (2), the total buying amount calculation (3), and the total selling amount (4). ).

The net profit and loss list calculation program 170f 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 maximum minimum value, quantity, selling price, and commission rate. Net profit and loss calculation is based on the calculation of the stock price list using the minimum value (1), the calculation of the total selling amount (2), the total purchase amount calculation (3), the commission calculation (4), and the total profit or loss for each share price on the stock price list. Process (5).

The net profit and loss list calculation program 170g is a program that calculates the ratio of net profit and loss to the purchase price for each stock on the stock price list. The net profit or loss ratio is the ratio of net profit and purchase amount remaining after deducting a fee from total profit or loss when a share is sold to a particular stock price. Net profit / loss ratio = ((total sale amount-total purchase amount-commission) / total purchase amount) * 100. The input and output variables for net profit and loss rate calculations are maximum minimum value, quantity, selling price, and commission rate. The net profit / loss ratio calculation is based on the calculation of the stock price list using the minimum value (1), the calculation of the total selling amount of each stock price (2), the calculation of the total purchase amount (3), the commission calculation (4), and the total profit or loss. Negative net income calculation (5), and net profit and loss divided by the total purchase amount (6).

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

18A to 18F illustrate examples of the stock price on the stock trading graph and the profit and loss list according to the stock price of the cyber trading system 200. For example, the maximum value of Dongbu E & C's stock graph is 9,000 won and the minimum scale is 5,000 won, so the number of shares is about 400 at 10 won units. Since there are seven profit and loss items for each share price, the number of profit and loss items is about 2,800. 18A-18F are instantaneous calculations by the investor simply selecting drop-down 250e with a mouse.

In the past, the investor has manually calculated (takes tens of seconds) the specific cell shown in FIGS. 18A to 18F, and only one cell can be calculated at a time. This is because the cyber trading system did not provide profit and loss data values.

18A to 18F show all profit and loss data for all prices in the stock price graph range, so that the investor can obtain the value of any profit or loss. In addition, the data may be edited and selectively displayed in various ways according to screen characteristics or a user's request.

19 is an example of a stock price screen 250 according to the present invention. In the above example, an investor bought 1,380 shares of Dongbu E & C for W6,600. If the investor wishes to know the gain or loss of future share price fluctuations, the stock graph window (250d) contains the limit of profit realization and the stop loss limit set by the investor in the condition setting (250c) based on the purchase price (W6,600). The condition line is shown in the stock graph window 250d together with the buying line.

In addition, the profit and loss window (250g) is displayed at the same time the total profit and loss corresponding to the stock price scale (9000, 8500 .... 5500, 5000) of the stock graph window, the investor can determine the stock price and profit and loss at the same time.

If you want to know more detailed price and profit and loss per share, refer to the stock price and total profit and loss per share, which are increased or decreased by 10 won unit from the maximum value (KRW 9000) to minimum value (KRW 5000) in the profit and loss data window (250h). Just do it.

The drop down button 250e is a button for selecting profit and loss items that an investor wants to know. When the button is selected, seven profit and loss item selection windows appear.

As mentioned above, since the stock price list and various gains and losses for each stock price are simultaneously displayed on the stock graph, the investor can judge the stock price + profit and loss, and compare the condition line with the conventional method. It can be visually confirmed to provide an improved cyber trading service that does not require calculation.

In other words, the stock price graph and profit and loss information are combined and displayed on the improved stock graph screen, so investors can (1) determine the progress of the stock price, and (2) the high point, the lowest point, the selling price, the profit realization, the stop loss price band, and the buy price line. In addition, the stock price and profit and loss information can be judged comprehensively, thus enabling a more favorable investment environment.

As a result, investors can judge stock price and profit and loss information in one place at the same time, and experience synergies that combine key information. As a result, they will be able to maximize their own profits by realizing appropriate profits or making bold stoppages.

20 illustrates the current state of the stock price and profit and loss and the concept of the stock price and profit and loss target in the present invention. An object of the present invention is to provide an investor with a profit and loss analysis value as many as the number of stock prices exist objectively for a particular item.
