Description

A device for managing data on stock trading using a first-in-first-out method and a method for managing stock trading data using the same

The present invention relates to a first-in-first-out method trading data management device and a trading method using the same (APPARATUS FOR MANAGING ITEM TRADING DATA BASD ON LAST-IN-FIRST-OUT AND METHOD USING THE SAME), more specifically It is related to technology that can calculate profits for each item based on the first-in-first-out method.

The present invention claims the benefit of the filing date of Korean Patent Application No. 10-2016-0073201 filed on June 13, 2016, the entire contents of which are incorporated herein.

Online stock trading systems that trade stocks, futures or options, etc. online, have data in the form of an average purchase price.

The average purchase price method refers to the unit price divided by the purchase amount when the stock, futures or options are purchased. If the sale is made, the average purchase price of the shares held does not change. If you make a purchase after a sale, the average purchase price is (the number of holdings after the sale * the average purchase price after the sale + the selling price * the number of purchases)/retention amount.

Currently, with the average price of the purchase, the actual sales gains, valuation returns, and valuation gains and losses are calculated. The actual sales gains and losses are calculated as (Sell-Buy Average) * Selling Quantity, the valuation rate is calculated as 1-(Buy Average / Present Price), and the valuation gains and losses are calculated as (Current Price-Buy Average) * Holding Quantity. have.

This method of average purchase price can be effectively used in transactions that buy and sell real goods, and can be used especially when accounting is required.

However, in financial products such as stocks, futures, and options, each trader frequently trades with each other due to a change in price. In the transaction of a product, the direction of the transaction does not change even when the price changes (producer -> distributor -> consumer), but there is not always a certain direction in the transaction of financial products such as stocks, futures and options, and each other is a supplier. However, there is a characteristic that each other becomes a consumer. In such a transaction, it is much more important that the amount of the most recent purchase than the average purchase price of each person. Therefore, those who buy and sell financial products such as stocks, futures, and options are the basis for the judgment of the sale. In many cases, the recently purchased amount is often used as a judgment criterion.

In addition, by definition of the average purchase price, the price that has the most influence on the average purchase price is the most recently purchased price. However, in trading financial products such as stocks, futures, and options, in many cases, selling is most likely to sell the most recently purchased product for profit or to judge that the purchase was wrong.

Therefore, there is a need to change the method of calculating the realization gains, valuation returns, and valuation gains and losses that are calculated with the current average purchase price. Based on the first-in-first-out method of this system, the purchase average price, real sales gains, valuation returns, There is an urgent need for a brand new stock trading system that can generate valuation gains and losses.

As a related prior art, there is Korean Patent Publication No. 10-2014-0134060, published on November 21, 2014 (name: online stock trading journal creation method and system).

Here, repeated descriptions, well-known functions that may unnecessarily obscure the subject matter of the present invention, and detailed description of the configuration will be omitted. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art. Accordingly, the shape and size of elements in the drawings may be exaggerated for a clearer explanation.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram showing a stock trading system of a first-in-first-out method according to an embodiment of the present invention.

Referring to FIG. 1, a stock trading system of a first-in-first-out method according to an embodiment of the present invention includes a stock trading data management device 110 and terminals 120-1 to 120-N.

The stock transaction data management device 110 may calculate the stock-specific profit of each stock based on a first-in-first-out method. A general online trading system calculates profit by database of trading data based on the average purchase price.

However, in fact, selling stocks, futures or options, etc., means selling recently purchased stocks, not selling previously purchased stocks. In other words, in practice, trading corresponding to the first-in-first-out method is carried out, but it is difficult to provide accurate profit information about the stocks in the online stock trading system because the profits are calculated using the accounting method based on the average purchase price.

In order to solve this problem, the stock trading system according to the present invention provides profit information for stocks based on a first-in-first-out method, so that the stock holder can accurately grasp the stock holding situation and profit/loss information generated by trading. I can do it.

At this time, the stock trading data management apparatus 110 stores the number of purchases and the number of purchases for a specific stock, and stores the cumulative trading profits and trading profits calculated by a first-in-first-out method whenever a stock sale of a specific sale occurs.

At this time, the relative selling price can be stored from the most recently purchased quantity to the selling quantity, and the cumulative trading profit and trading profit can be calculated based on the relative selling price.

At this time, when the selling quantity of the specific selling is greater than the most recently purchased quantity, two or more selling relative buyings are stored, and the trading gains and trading gains accumulated for each of the two or more selling relative buyings can be calculated.

At this time, the trading profit may be calculated by subtracting the purchase fee, the selling fee, and the tax from the value obtained by multiplying the selling amount by the amount obtained by subtracting the relative selling price from the specific selling price.

In addition, the item transaction data management apparatus 110 calculates the average selling price of the items held in the first-in-first-out method by using the cumulative trading profit of the first-in-first-out method.

At this time, the average purchase price of the stocks of the first-in-first-out method can be calculated by dividing the input amount by the cumulative trading profit by the remaining amount.

In addition, the stock transaction data management device 110 calculates an investment profit corresponding to the average purchase price of the stock held.

At this time, the investment profit can be calculated by subtracting the input amount from the amount of the current stock of the holding item multiplied by the remaining amount.

In addition, the item trading data management apparatus 110 classifies and displays the first element of the investment profit generated by the trading of the specific item and the second element of the investment profit corresponding to the price fluctuation of the remaining amount of the specific item.

* At this time, the first element may be calculated using a cumulative trading profit.

At this time, the second element may be calculated by multiplying the remaining amount by the amount obtained by subtracting the current price from the average purchase price of the held item.

At this time, the sum of the first element and the second element may correspond to the investment profit.

The terminals 120-1 to 120-N may correspond to a means for a user who holds stocks to check stock trading data.

At this time, the terminal (120-1 ~ 120-N) is a smart phone (Smart Phone), a portable terminal (Portable Terminal), a mobile terminal (Mobile Terminal), personal information terminal (Personal Digital Assistant: PDA), PMP (Portable Multimedia) Player) terminal, Telematics terminal, Navigation terminal, Personal computer, Notebook computer, Slate PC, Tablet PC, Ultrabook, Wearable device Device, for example, a watch-type terminal (Smartwatch), a glass-type terminal (Smart Glass), a head mounted display (HMD), etc., a Wibro terminal, an IPTV (Internet Protocol Television) terminal, a smart TV, and digital broadcasting It can correspond to various terminals such as terminals, televisions, 3D televisions, home theater systems, audio video navigation (AVN) terminals, audio/video (A/V) systems, and flexible terminals. have.

At this time, the terminals 120-1 to 120-N may receive information about the item transaction from the item transaction data management device 110 based on the network 130.

At this time, the network 130 is a concept encompassing both a network used in the past and a network that can be developed in the future. For example, the network is an IP network that provides a large-scale data transmission/reception service and an Internet-free data service through an Internet protocol (IP), and an IP network structure that integrates different networks based on IP. IP) network, including wired networks, Wibro (Wireless Broadband) networks, 3G mobile communication networks including WCDMA, HSDPA (High Speed Downlink Packet Access) networks, and 3.5G mobile networks including LTE networks, including LTE advanced It can be made by combining one or more of a 4G mobile communication network, a satellite communication network, and a Wi-Fi network.

FIG. 2 is a block diagram showing an example of a device transaction data management device illustrated in FIG. 1.

Referring to FIG. 2, the device transaction data management device 110 illustrated in FIG. 1 includes a memory 210 and a processor 220.

The memory 210 stores the number of purchases and the number of purchases for a specific item, and stores the cumulative trading profits and trading profits that are calculated by a first-in-first-out method whenever an item is sold at a specific sale.

At this time, the first-in-first-out method may correspond to a method in which when the sale of a specific sale for a specific item occurs, the remaining amount of the purchase by the most recent purchase is sold.

Currently, the valuation of stocks, futures, and stock trading is based on the average number of purchases using the accounting method. Therefore, even when an item is sold, it is judged that the stock has been sold at the average number of shares, and correspondingly, the profit from the sale and the holding price of the remaining stocks are evaluated.

However, actually selling stocks, futures, options, etc. may be selling recently purchased stocks, but not selling previously purchased stocks. In this way, if the average selling price of stocks held is evaluated by the accounting method, it is impossible to accurately calculate the profit from the actual sale.

In order to solve this problem, the present invention is to provide a more accurate stock transaction information and various types of profit and loss information by providing a stock transaction data management device of a first-in-first-out method that matches the actual selling method.

At this time, the memory 210 may generate a field to record the purchase information according to each purchase, when a purchase for a specific event occurs, and store the purchase information in each field. For example, assuming that the purchase for item A has occurred, the number of sheets for the number of sheets in the field A and the number of sheets for the number of sheets A may be stored, respectively.

At this time, even if the purchase does not occur, if you already have stock or transfer, you can create the same field as when the purchase occurs and store it in the same format as the purchase information.

At this time, the number of purchases and the number of purchases may refer to the transaction unit price and quantity to be purchased when trading the stock. Therefore, for the stocks already held, the current unit price of the corresponding stock can be stored as a purchase, and the amount of the stocks held can be stored as a purchase quantity.

At this time, the memory 210, in order to calculate the cumulative trading profit and trading profit in a first-in-first-out method whenever an item is sold, the remaining amount of purchase, the relative amount of purchase, the relative date of purchase, the date and time of the purchase relative, You can store information such as purchase fees, selling fees and taxes.

At this time, the trading profit may mean the amount of profit or loss arising from the purchase and sale, and the cumulative sum of these may correspond to the cumulative trading profit.

At this time, the remaining amount of the purchase may correspond to the value remaining after subtracting the number of purchases of the sale occurring after the purchase, from the number of purchases purchased. Therefore, for each purchase, it is possible to subtract the sale quantity by the sale after the purchase from the remaining purchase amount until the remaining purchase amount becomes 0.

If the purchase quantity is repurchased when the remaining quantity of the corresponding purchase is not 0, the selling quantity by the subsequent selling may be excluded from the remaining quantity of the most recent buying quantity. That is, the selling quantity by selling is deducted until the remaining buying quantity for the most recent buying becomes 0, and when the remaining buying quantity by the most recent buying becomes 0, the selling quantity remaining from the remaining buying quantity by the previous buying. Can be deducted.

At this time, the relative selling price may correspond to the selling price for one week of the stock to be sold. That is, it can be judged that each single stock corresponding to the relative selling amount is sold corresponding to the relative selling price.

In addition, the date of purchase relative to the sale may correspond to the date and time of the sale in which the sale corresponding to the relative selling amount of the purchase occurred.

At this time, the purchase fee, the sale fee, and the tax may correspond to the amount obtained by dividing the amount arising from the purchase or sale at a predetermined rate. At this time, the amount of money generated by buying or selling can be reduced by a unit of 1, and the actual amount and the difference can be added to the last quantity.

In addition, the memory 210 generates fields for storing information according to each sale every time a sale occurs, in order to calculate and store the cumulative trading profits and trading profits in a first-in-first-out method. You can store information such as the relative purchase quantity, the relative purchase price, the date and time of the relative purchase, and the relative purchase commission.

At this time, the selling price and the selling quantity may mean the trading unit price and quantity to be sold when trading the stock.

At this time, the relative selling quantity of the purchase may correspond to the selling quantity of the deducted sales until the remaining quantity of the buying is zero. For example, for item A, it can be assumed that the number of purchases of the purchases that occurred at 9:00 am on May 1, 2016 is 100, and that the sale quantity of the sales that occurred at 1 pm and 3 pm on the same day is 50, respectively. . At this time, the relative selling amount of the purchase for the stock A may be stored as 50 each by two selling.

Therefore, when the number of purchases for a specific item is greater than the number of purchases of the corresponding purchase after the occurrence of the purchase, the number of purchases may correspond to the relative amount of the purchase. That is, since the number of purchases is exhausted and the remaining amount of purchases is zero due to the sale occurring after the purchase, all of the purchase quantities may correspond to the relative purchase amount of purchases.

In addition, after the purchase of a specific item occurs, when the selling quantity is less than the buying quantity of the corresponding buying quantity, the selling quantity itself may correspond to the relative selling quantity. At this time, since the remaining amount of the purchase is not 0, the selling quantity by the next selling may be the relative selling quantity.

Therefore, the relative number of sheets sold relative to the number of sheets may be stored in a plurality.

In addition, the date of purchase relative to the sale may correspond to the date and time when the purchase occurred corresponding to the relative amount of the sale.

At this time, the relative selling price may correspond to the buying price for one week of the stock to be purchased. That is, it can be determined that each single stock corresponding to the relative purchase quantity is bought corresponding to the relative purchase quantity.

In this case, the relative selling price is stored from the most recently purchased quantity to the selling quantity, and the cumulative trading gains and trading profits can be calculated based on the relative selling quantity.

Therefore, the relative selling quantity relative to the selling may also correspond to a value equal to or smaller than the selling quantity by selling from among the buying quantity by the most recent buying when the selling occurs. That is, when the number of purchases by the most recent purchase when the sale occurs is greater than the number of purchases by the sale, the value of the sale amount may correspond to the relative purchase amount of the sale.

At this time, when the selling quantity of the specific selling is greater than the most recently purchased quantity, two or more selling relative buyings are stored, and the trading gains and trading gains accumulated for each of the two or more selling relative buyings can be calculated.

In other words, when the number of purchases by the most recent purchase is less than the number of purchases by selling when the sale occurs, it is equal to or less than the number of remaining sales from the remaining quantity of the previous purchase and the remaining quantity Can correspond to a value.

For example, it can be assumed that the selling quantity due to the selling is 30, the buying quantity according to the most recent first buying is 20, and the remaining quantity of buying due to the second buying before the first buying is 20. At this time, the relative selling quantity relative to the sale may correspond to 10, such as the remaining quantity 20 from the remaining quantity 20 from the first purchase and the remaining quantity 20 from the second purchase.

That is, when the number of purchases by the most recent purchase is less than the number of purchases by the sale, at least two or more relative purchase amounts may exist. Therefore, there may be two or more relative sellers to sell in the same manner as the relative sellers to sell.

At this time, the trading profit may be calculated by subtracting the purchase fee, the selling fee, and the tax from the value obtained by multiplying the selling amount by the amount obtained by subtracting the relative selling price from the specific selling price.

In other words, the trading profit can be calculated as follows.

Trading margin = ((Sell-Sell relative to sell) * Sell quantity)-Buy fee-Sell fee and tax

Therefore, when there are two or more relative sellers to sell, it is possible to calculate the trading profits for each of the relative sellers to sell and sum them up.

At this time, according to the existing accounting method, it is possible to calculate by subtracting the purchase fee, the selling fee, and the tax from the value obtained by subtracting the average purchase price from the specific selling price and the selling quantity. That is, it can be determined that the selling quantity by selling is deducted from the buying quantity by all buying that occurred for a specific item, rather than a first-in-first-out method that subtracts selling quantity by selling from the most recent buying quantity.

Therefore, when the trading profit is calculated using the conventional accounting method and the first-in-first-out method according to the present invention, the value can be calculated differently.

At this time, if you have previously held stocks, or if you have transferred stocks from another account, the value of the stock price at the time of transfer multiplied by the quantity transferred may correspond to the purchase amount. In addition, in the case of a transfer, the value multiplied by the current price of the item at the time of transfer and the amount transferred can correspond to the selling amount.

The processor 220 calculates the average selling price of the stocks of the first-in-first-out method using the cumulative trading gains of the first-in-first-out method, and calculates an investment profit corresponding to the average purchase price of the held item.

At this time, the average purchase price of the stocks held may correspond to the average purchase price of the balances of the stocks currently held.

At this time, the average selling price of the held item may correspond to a value obtained by dividing the sum of the input amount and the cumulative trading profit in the corresponding item by the remaining amount.

At this time, the first element of the investment profit arising from the trading of a specific item and the second element of the investment profit corresponding to the price fluctuation of the remaining amount of the specific item may be classified and displayed. In other words, the investment profit may correspond to the concept including both the trading profit generated by the sale of a specific item and the profit or loss according to the stocks held.

As described above, by separately providing the first and second elements of the investment profit, it is possible to simultaneously sell the stock and provide the information on the profit actually obtained, as well as the profit information due to the change in the value of the stock held.

At this time, the first element may be calculated using a cumulative trading profit. In other words, the accumulated trading profit for each sale may correspond to the first element of the investment profit for a specific item.

At this time, the second element may be calculated by multiplying the remaining amount by the amount obtained by subtracting the current price from the average purchase price of the held item. At this time, the average purchase price of the held item is the value obtained by dividing the sum of the input amount and the cumulative trading profit by the remaining amount, that is, when evaluating the amount for one stock, the cumulative trading profit is also considered as the input amount. The second element may not include margins generated by selling. In other words, it can mean only the revenue generated by the price fluctuations of stocks that are purely equivalent to the remaining balance.

Therefore, the sum of the first element and the second element may correspond to the investment profit.

At this time, the investment profit can also be calculated by subtracting the input amount from the amount multiplied by the remaining amount and the present price. When calculating the investment profit in this way, it is possible to use the existing accounting method or the last-in, first-out method of the present invention. Regardless, the return on investment can be accurately calculated.

However, in the case of calculating and summing the first and second elements using the existing accounting method, an accurate investment profit is not calculated. This may be due to the fact that the investment profit corresponding to the price fluctuation of the trading profit and the remaining balance calculated by the existing accounting method is not accurate.

In the existing accounting method, trading profit is calculated by multiplying the selling price by the amount obtained by subtracting the average purchase price from the current price. At this time, the average purchase price is considered only when buying stocks, futures or options, and is the value obtained by dividing the purchase amount by the number of purchases.

In addition, in the existing accounting method, the investment price corresponding to the price fluctuation of the remaining balance is calculated by multiplying the amount obtained by subtracting the average purchase price from the current price. That is, since the value is calculated using the purchase average price calculated by considering only the unconditional purchase without considering the purchase or the sale, it is difficult to calculate an accurate investment profit, including the trading profit already calculated in the first element.

However, after calculating the trading profit in the first-in-first-out method according to the present invention to calculate the cumulative trading profit of the first element, the price of the remaining amount of the second element as the average purchase price of the held stock calculated using the cumulative trading profit By calculating the investment profit corresponding to the fluctuation, the sum of the first element and the second element may correspond to the correct investment profit.

At this time, the input amount may correspond to the purchase amount, the purchase fee, the sale amount, the sale fee, and the accumulated tax. Accordingly, the investment profit may correspond to the sum of the profits from the trading profits generated in each sale and the profits on the remaining stocks.

At this time, the remaining balance indicates the number of shares currently held, and may correspond to a value obtained by subtracting the quantity sold. If there is a previously held stock, the remaining stock can be calculated by adding the previously held stock to the purchase quantity minus the selling quantity.

As described above, by providing the first element and the second element for the investment profit, respectively, profit/loss information for a specific item can be provided in more various ways.

At this time, the unit price can be managed by matching the average purchase price of the holding unit with the holding unit. Based on the matched information, it is possible to compare the holding price and the average buying price of the held item, and it is easy to determine whether the item is profit or loss based on the comparison amount.

At this time, the holding unit price may correspond to a value obtained by dividing the input amount by the holding amount of the stocks currently held.

By using the stock transaction data management apparatus 110, when trading stocks, futures, or options, it is possible to provide gains and losses of the stocks held by stocks or time according to the first-in-first-out method.

In addition, it may be possible to provide profit information of an item more accurately by calculating profit or loss based on a first-in-first-out method.

3 is an operation flowchart showing a method of managing item transaction data in a first-in-first-out method according to an embodiment of the present invention.

Referring to FIG. 3, in the method of managing data of a stock transaction of a first-in-first-out method according to an embodiment of the present invention, when a purchase occurs for a specific item, the number of sheets and the number of sheets are stored (S310).

At this time, whenever a purchase for a specific item occurs, a field for recording purchase information according to each purchase may be generated, and the number of purchases or the number of purchases corresponding to the purchase information may be stored in the generated field. For example, assuming that the purchase for item A has occurred, the number of sheets for the number of sheets in the field A and the number of sheets for the number of sheets A may be stored, respectively.

At this time, even if the purchase does not occur, it is possible to store the purchase information in the same way by generating the same field as when the purchase occurs even for stocks already held or transferred stocks.

At this time, the number of purchases and the number of purchases may refer to the transaction unit price and quantity to be purchased when trading the stock. Therefore, for the stocks already held, the current unit price of the corresponding stock can be stored as a purchase, and the amount of the stocks held can be stored as a purchase quantity.

In addition, in the method for managing data of stocks in a first-in-first-out method according to an embodiment of the present invention, when a sale of a specific selling occurs for a specific item, the cumulative trading gains and trading profits are calculated and stored in a first-in-first-out method (S320).

At this time, in order to calculate the cumulative trading profit and trading profit every time a stock sale occurs, the remaining balance of each purchase, the relative amount of the purchase, the relative price of the purchase, the date and time of the purchase relative, the purchase fee, the selling fee And information such as taxes.

At this time, the trading profit may mean the amount of profit or loss arising from the purchase and sale, and the cumulative sum of these may correspond to the cumulative trading profit.

At this time, the remaining amount of the purchase may correspond to the remaining value by subtracting the number of purchases of the sale occurring after the purchase, from the number of purchases purchased. Therefore, for each purchase, it is possible to subtract the selling quantity by the selling after the buying from the remaining buying quantity until the remaining buying quantity becomes 0.

If the purchase quantity is repurchased in a state where the remaining quantity of the corresponding purchase is not 0, the selling quantity due to the subsequent selling can be subtracted from the remaining quantity of the most recent buying quantity. That is, the selling quantity by selling is deducted until the remaining buying quantity for the most recent buying becomes 0, and when the remaining buying quantity by the most recent buying becomes 0, the selling quantity remaining from the remaining buying quantity by the previous buying. Can be deducted.

At this time, the relative selling price may correspond to the selling price for one week of the stock to be sold. That is, it can be judged that each single stock corresponding to the relative selling amount is sold corresponding to the relative selling price.

In addition, the date of purchase relative to the sale may correspond to the date and time of the sale in which the sale corresponding to the relative selling amount of the purchase occurred.

At this time, the purchase fee, the sale fee, and the tax may correspond to the amount obtained by dividing the amount arising from the purchase or sale at a predetermined rate. At this time, the amount of money generated by buying or selling can be reduced by a unit of 1, and the actual amount and the difference can be added to the last quantity.

In addition, in order to calculate and store cumulative trading profits and trading profits in a first-in-first-out method, each time a sale occurs, the amount of the sale, the amount of the sale, the amount of the relative sale, the date of the relative sale, the date and time of the purchase relative to the seller, the time of the seller relative Information can be stored.

At this time, the selling price and the selling quantity may mean the trading unit price and quantity to be sold when trading the stock.

At this time, the relative selling quantity of the purchase may correspond to the selling quantity of the deducted sales until the remaining quantity of the buying is zero. For example, for item A, it can be assumed that the number of purchases of the purchases that occurred at 9:00 am on May 1, 2016 is 100, and that the sale quantity of the sales that occurred at 1 pm and 3 pm on the same day is 50, respectively. . At this time, the relative selling amount of the purchase for the stock A may be stored as 50 each by two selling.

Therefore, when the number of purchases for a specific item is greater than the number of purchases of the corresponding purchase after the occurrence of the purchase, the number of purchases may correspond to the relative amount of the purchase. That is, since the number of purchases is exhausted and the remaining amount of purchases is zero due to the sale occurring after the purchase, all of the purchase quantities may correspond to the relative purchase amount of purchases.

In addition, after the purchase of a specific item occurs, when the selling quantity is less than the buying quantity of the corresponding buying quantity, the selling quantity itself may correspond to the relative selling quantity. At this time, since the remaining amount of the purchase is not 0, the selling quantity by the next selling may be the relative selling quantity.

Therefore, the relative number of sheets sold relative to the number of sheets may be stored in a plurality.

In addition, the date of purchase relative to the sale may correspond to the date and time when the purchase occurred corresponding to the relative amount of the sale.

At this time, the relative selling price may correspond to the buying price for one week of the stock to be purchased. That is, it can be determined that each single stock corresponding to the relative purchase quantity is bought corresponding to the relative purchase quantity.

At this time, from the most recently purchased quantity to the selling quantity corresponding to the selling amount, the relative selling price is stored, and the trading profit and the cumulative trading profit can be calculated based on the selling relative purchase price.

Therefore, the relative selling quantity relative to the selling may also correspond to a value equal to or smaller than the selling quantity by selling from among the buying quantity by the most recent buying when the selling occurs. That is, when the number of purchases by the most recent purchase when the sale occurs is greater than the number of purchases by the sale, the value of the sale amount may correspond to the relative purchase amount of the sale.

At this time, when the selling quantity of the specific selling is greater than the most recently purchased quantity, two or more selling relative buyings are stored, and the trading gains and trading gains accumulated for each of the two or more selling relative buyings can be calculated.

In other words, when the number of purchases by the most recent purchase is less than the number of purchases by selling when the sale occurs, it is equal to or less than the number of remaining sales from the remaining quantity of the previous purchase and the remaining quantity Can correspond to a value.

For example, it can be assumed that the selling quantity due to the selling is 30, the buying quantity according to the most recent first buying is 20, and the remaining quantity of buying due to the second buying before the first buying is 20. At this time, the relative selling quantity relative to the sale may correspond to 10, such as the remaining quantity 20 from the remaining quantity 20 from the first purchase and the remaining quantity 20 from the second purchase.

That is, when the number of purchases by the most recent purchase is less than the number of purchases by the sale, at least two or more relative purchase amounts may exist. Therefore, there may be two or more relative sellers to sell in the same manner as the relative sellers to sell.

At this time, the trading profit may be calculated by subtracting the purchase fee, the selling fee, and the tax from the value obtained by multiplying the selling amount by the amount obtained by subtracting the relative selling price from the specific selling price.

In other words, the trading profit can be calculated as follows.

Trading margin = ((Sell = Sell relative to sell) * Sell quantity)-Buy fee-Sell fee and tax

Therefore, when there are two or more relative sellers to sell, it is possible to calculate the trading profits for each of the relative sellers to sell and sum them up.

At this time, according to the existing accounting method, it is possible to calculate by subtracting the purchase fee, the selling fee, and the tax from the value obtained by subtracting the average purchase price from the specific selling price and the selling quantity. That is, it can be determined that the selling quantity by selling is deducted from the buying quantity by all buying that occurred for a specific item, rather than a first-in-first-out method that subtracts selling quantity by selling from the most recent buying quantity.

Therefore, when the trading profit is calculated using the conventional accounting method and the first-in-first-out method according to the present invention, the value can be calculated differently.

At this time, if you have previously held stocks, or if you have transferred stocks from another account, the value of the stock price at the time of transfer multiplied by the quantity transferred may correspond to the purchase amount. In addition, in the case of a transfer, the value multiplied by the current price of the item at the time of transfer and the amount transferred can correspond to the selling amount.

In addition, in the method of managing the transaction data of the first-in-first-out method according to an embodiment of the present invention, the average selling price of the held items in the first-in-first-out method is calculated using the cumulative trading profit (S330).

At this time, the average purchase price of the stocks held may correspond to the average purchase price of the balances of the stocks currently held.

At this time, the average selling price of the held item may correspond to a value obtained by dividing the sum of the input amount and the cumulative trading profit in the corresponding item by the remaining amount.

In addition, the method of managing data of a stock transaction of a first-in-first-out method according to an embodiment of the present invention calculates an investment profit corresponding to the average purchase price of the stock (S340).

At this time, the first element of the investment profit arising from the trading of a specific item and the second element of the investment profit corresponding to the price fluctuation of the remaining amount of the specific item may be classified and displayed. In other words, the investment profit may correspond to the concept including both the trading profit generated by the sale of a specific item and the profit or loss according to the stocks held.

As described above, by separately providing the first and second elements of the investment profit, it is possible to simultaneously sell the stock and provide the information on the profit actually obtained, as well as the profit information due to the change in the value of the stock held.

At this time, the first element may be calculated using a cumulative trading profit. In other words, the accumulated trading profit for each sale may correspond to the first element of the investment profit for a specific item.

At this time, the second element may be calculated by multiplying the remaining amount by the amount obtained by subtracting the current price from the average purchase price of the held item. At this time, the average purchase price of the held item is the value obtained by dividing the sum of the input amount and the cumulative trading profit by the remaining amount, that is, when evaluating the amount for one stock, the cumulative trading profit is also considered as the input amount. The second element may not include margins generated by selling. In other words, it can mean only the revenue generated by the price fluctuations of stocks that are purely equivalent to the remaining balance.

Therefore, the sum of the first element and the second element may correspond to the investment profit.

At this time, the investment profit can also be calculated by subtracting the input amount from the amount multiplied by the remaining amount and the present price. When calculating the investment profit in this way, it is possible to use the existing accounting method or the last-in, first-out method of the present invention. Regardless, the return on investment can be accurately calculated.

However, in the case of calculating and summing the first and second elements using the existing accounting method, an accurate investment profit is not calculated. This may be due to the fact that the investment profit corresponding to the price fluctuation of the trading profit and the remaining balance calculated by the existing accounting method is not accurate.

In the existing accounting method, trading profit is calculated by multiplying the selling price by the amount obtained by subtracting the average purchase price from the current price. At this time, the average purchase price is considered only when buying stocks, futures or options, and is the value obtained by dividing the purchase amount by the number of purchases.

In addition, in the existing accounting method, the investment price corresponding to the price fluctuation of the remaining balance is calculated by multiplying the amount obtained by subtracting the average purchase price from the current price. That is, since the value is calculated using the purchase average price calculated by considering only the unconditional purchase without considering the purchase or the sale, it is difficult to calculate an accurate investment profit, including the trading profit already calculated in the first element.

However, after calculating the trading profit in the first-in-first-out method according to the present invention to calculate the cumulative trading profit of the first element, the price of the remaining amount of the second element as the average purchase price of the held stock calculated using the cumulative trading profit By calculating the investment profit corresponding to the fluctuation, the sum of the first element and the second element may correspond to the correct investment profit.

At this time, the input amount may correspond to the purchase amount, the purchase fee, the sale amount, the sale fee, and the accumulated tax. Accordingly, the investment profit may correspond to the sum of the profits from the trading profits generated in each sale and the profits on the remaining stocks.

At this time, the remaining balance indicates the number of shares currently held, and may correspond to a value obtained by subtracting the quantity sold. If there is a previously held stock, the remaining stock can be calculated by adding the previously held stock to the purchase quantity minus the selling quantity.

As described above, by providing the first element and the second element for the investment profit, respectively, profit/loss information for a specific item can be provided in more various ways.

At this time, the unit price can be managed by matching the average purchase price of the holding unit with the holding unit. Based on the matched information, it is possible to compare the holding price and the average buying price of the held item, and it is easy to determine whether the item is profit or loss based on the comparison amount.

At this time, the holding unit price may correspond to a value obtained by dividing the input amount by the holding amount of the stocks currently held.

Through this method of managing trading data, it is possible to provide profit or loss of stocks held by stocks, futures, or options according to the first-in-first-out method.

In addition, it may be possible to provide profit information of an item more accurately by calculating profit or loss based on a first-in-first-out method.

4 is a diagram showing an example of stock trading data using the stock trading data management method according to the present invention.

Referring to FIG. 4, the stock trading data using the stock trading data management method according to the present invention may store corresponding values in fields corresponding to the number of purchases and the number of purchases each time a purchase of a specific item occurs.

At this time, the method for managing the item transaction data according to the present invention may input data based on a first-in-first-out method when a sale occurs.

In this case, the first-in-first-out method may correspond to a method of subtracting the selling quantity from the most recently purchased quantity when the selling occurs.

For example, when checking the trading concluded on November 19, 2015 in the item trading data shown in FIG. 4, it can be confirmed that the selling occurred corresponding to the selling price corresponding to 9,005 won and 23 selling quantities. . At this time, the 23 selling quantity may be deducted from the 157 buying quantity purchased on November 16, 2015, which is the most recent from November 19, 2015.

For another example, when checking the trading concluded on January 19, 2016 in the stock trading data shown in FIG. 4, it can be confirmed that the selling occurred for the corresponding stock at 8,160 won and 23 selling quantities. have. At this time, the 23 selling quantity may be deducted from the 24 buying quantity purchased on January 18, 2016, which is the most recent from January 19, 2016 when the corresponding selling occurred.

As described above, since the selling quantity is subtracted from the most recently purchased buying quantity from the selling timing each time a selling occurs, in order to calculate the trading profit, the selling relative selling may be stored each selling.

For example, in the stock trading data shown in FIG. 4, the sale that occurred on November 19, 2015 is the most recent purchase on November 16, 2015, and the purchase of 8,740 won (A) can be stored as a relative purchase. have. In addition, the next selling on November 26, 2015 may also store 8,740 (A) as the selling relative to the number of buying on November 16, 2015. At this time, since the number of purchases of the number of purchases that occurred on November 16, 2015 is the amount that can cover all the sales volumes for the two sales that occurred after the purchase, the number of purchases relative to each of the two sales can be stored. have.

However, in the stock transaction data shown in FIG. 4, when the relative seller number of the seller of the sale occurred on February 25, 2016, the field 420 can be confirmed that a total of five relative seller sellers are stored.

This is because the most recent purchase quantity on February 11, 2016 from the sale on February 25, 2016, was mostly deducted by the sale on February 16, 2016. In other words, the sales volume of the sale that occurred on February 25, 2016 is 23, but the most recent purchase on February 11, 2016 was 1, so the purchase amount on February 11, 2016 It can be seen that the sales volume was subtracted from the remaining balance of the previous purchases.

Therefore, in the sales that occurred on February 25, 2016, shown in FIG. 4, the number of purchases on February 11, 2016 was 7,915 won (I), and the number of purchases on January 26, 2016 was 7,915 won. (H), the number of purchases that occurred on January 20, 2016 was 7,915 won (G), the number of purchases that occurred on January 18, 2016 was 7,905 (F), and the number of purchases that occurred on January 7, 2016 You can save all 8,325 won (F) as a relative purchase.

5 to 6 are views showing another example of stock trading data using the stock trading data management method according to the present invention.

5 to 6, the stock trading data of the present invention may store the relative purchase price in the field of the corresponding purchase every time a sale occurs.

For example, in the stock transaction data shown in FIG. 6, the sales 610 that occurred on February 16, 2016, the sales 620 that occurred on February 25, 2016, and the sales that occurred on March 10, 2016 (630). If you combine all the sales quantities of ), you can see that the three sales (610, 620, 630) exceed the number of purchases of the most recent purchase on February 11, 2016. In such a case, the selling may be performed by checking the remaining amount of the number of purchases that occurred on February 11, 2016, and at least one number of purchases that occurred before that.

In other words, 23 sales (A) of the sales (610) that occurred on February 16, 2016 are deducted as 24 of the most recent purchases of February 11, 2016. The remaining amount of the number of purchases generated in may be stored as one.

At this time, in the field of the relative amount of sales of the number of purchases that occurred on February 11, 2016, the number of relative sales (23) of the number of sales corresponding to 23 (A) of the number of sales of sales (610) occurred on February 16, 2016. Can be saved. In addition, in the field of the relative selling of the number of purchases that occurred on February 11, 2016, the selling of the sale (610) that occurred on February 16, 2016 may be stored as a relative selling price of 8,155 won.

Thereafter, 23(B) of the sales amount of the sales 620 occurred on February 25, 2016, the most recent purchase of the remaining amount on February 11, 2016 1, the remaining amount on January 26, 2016 1 Remaining number of purchases, 1 Remaining number of purchases on January 20, 2016, 1 Remaining purchases on January 18, 2016, and 1 Remaining purchases on January 7, 2016 23 By deducting all of them, the remaining balance of the number of purchases that occurred on January 7, 2016 can be stored as four, and the remaining amount of purchases can be stored as zero.

At this time, in the field of the relative amount of purchase of the number of purchases that occurred on February 11, 2016, in the field of the amount of relative sale, which corresponds to one of 23 (B) of the sale amount of sales (620) occurred on February 25, 2016 ( B) can be stored. In addition, in the field of the relative selling of the number of purchases that occurred on February 11, 2016, the selling of the sale (620) that occurred on February 25, 2016 may be stored as a relative selling price of KRW 8,575.

At this time, in the field of the relative amount of sales of the number of purchases that occurred on January 26, 2016, the number of relative sales of the number of purchases corresponding to one of 23 (B) of the sales amount of sales (620) occurred on February 25, 2016 ( B) can be stored. In addition, in the field of relative purchase of the number of purchases that occurred on January 26, 2016, the sale of the sale (620) that occurred on February 25, 2016 can be stored as a relative purchase price of KRW 8,575.

At this time, in the field of the relative amount of sales of the number of purchases that occurred on January 20, 2016, the field of the amount of relative sales that corresponds to one of 23 (B) of the selling quantity of sales 620 occurred on February 25, 2016 ( B) can be stored. In addition, in the field of relative purchase of the number of purchases that occurred on January 20, 2016, the sale of the sale (620) that occurred on February 25, 2016 may be stored as a relative purchase price of KRW 8,575.

At this time, in the field of the relative amount of sales of the number of purchases that occurred on January 18, 2016, the number of relative sales of the number of purchases corresponding to 1 of 23 (B) of the amount of sales (620) occurred on February 25, 2016 ( B) can be stored. In addition, in the field of relative selling of the number of purchases that occurred on January 18, 2016, the selling of the sale (620) that occurred on February 25, 2016 may be stored as a relative selling price of KRW 8,575.

At this time, in the field of relative sales of the number of purchases that occurred on January 7, 2016, the number of relative sales of 19 corresponding to 19 of the 23 (B) of the sales amount of sales (620) occurred on February 25, 2016 ( B) can be stored. In addition, in the field of relative purchase of the number of purchases that occurred on January 7, 2016, the sale of the sale (620) that occurred on February 25, 2016 may be stored as a relative purchase price of KRW 8,575.

Thereafter, 23 of the selling quantity of the sale 630 that occurred on March 10, 2016 is 4 of the most recent buying, which occurred on January 7, 2016, which is the most recent buying, while the remaining quantity is 0, and 1 of 2016. By subtracting all the remaining amount of the number of purchases that occurred on the 4th of the month to 24, the remaining amount of the number of purchases that occurred on the 4th of January 2016 can be stored as 5, and the remaining amount of the number of purchases that occurred on the 7th of January 2016 can be stored as 0.

At this time, in the field of the relative amount of purchase of the number of purchases that occurred on January 7, 2016, the number of relative amount of purchases (4) corresponding to 4 of the 23 (C) of the amount of sale (630) that occurred on March 10, 2016 ( C) can be stored. In addition, in the field of relative purchase of the number of purchases that occurred on January 7, 2016, the sale of the sale (630) that occurred on March 10, 2016 can be stored as a relative purchase of 9,005 won.

At this time, in the field of relative sales of the number of purchases that occurred on January 4, 2016, the field of relative sales amount of 19 corresponding to 19 of 23 (C) of the number of sales of sales (630) occurred on March 10, 2016 ( C) can be stored. In addition, in the field of relative purchase of the number of purchases that occurred on January 4, 2016, the sale of the sale (630) that occurred on March 10, 2016 can be stored as a relative purchase price of KRW 9,005.

7 to 8 are diagrams illustrating an example of the results of calculating the stock trading data shown in FIGS. 5 to 6 with the stock trading data management method according to the present invention.

7 to 8, based on the stock transaction data shown in FIGS. 5 to 6, the trading profit field 710, the cumulative trading profit field 720, the holding unit price field 730, the average stock price It can be seen that the values corresponding to the field 740 and the holding item evaluation profit field 750 are respectively calculated.

At this time, the trading margin to be input into the trading margin field 710 may be calculated as follows.

Trading margin = ((Sell-Sell relative to sell) * Sell quantity)-Buy fee-Sell fee and tax

In other words, the trading profit is calculated by subtracting the relative purchase price, which is the purchase by the most recent purchase, from the selling price corresponding to the current price, thereby accurately calculating the trading profit by a first-in-first-out method suitable for trading financial instruments such as stocks, futures, and options. Can.

For example, the gains and losses on sale on November 19, 2015, shown in FIG. 5, are (9,005)-8,740) * 23-{((9,005 * 0.005) + (8,740 * 0.002)) *23} Can be calculated accordingly. In other words, the selling price corresponding to the current price is 9,005 won, which is the most recent buying, and the relative number of selling is 8,740 won, multiplied by 23 selling quantity, resulting in 6,095 won, 0.5% of the selling fee of 9,005 won and selling. 4,658 won, minus 1,437 won, which is the product multiplied by the selling quantity by adding 0.2% of the fee of 8,740 won, may correspond to the gains and losses from the sale on November 19, 2015.

At this time, if it is assumed that the trading profit is calculated in accordance with the existing accounting method, the sale is sold at 9,005 won minus the existing system holding unit price of 8,757 won on November 19, 2015 shown in FIGS. 7 and 8 As a result of multiplying the quantity by 23, 4,266 won was sold on November 19, 2015, minus 5,704 won, minus 0.5% of the purchase fee of 9,005 won and 0.2% of the selling fee of 8,757 won, minus 1,438, the product of the selling quantity. It can be calculated as the trading profit by. That is, it can be seen that a difference occurs in the trading profit and the amount of money by the first-in-first-out method according to the present invention.

At this time, the cumulative trading profit is a value calculated by accumulating the trading profits calculated at each sale, and the sum of the trading profits stored in the trading profit field 710 is located at the bottom of the cumulative trading profit field 720. Can.

At this time, the first element of the investment profit according to the present invention may correspond to a value input in the cumulative field of trade profit 720.

At this time, the second element of the investment profit according to the present invention may correspond to the value input to the holding item evaluation profit field 750 shown in FIGS. 7 and 8.

At this time, the gain of valuation of the held item, that is, the investment gain due to the price fluctuation of the held quantity may be calculated by multiplying the holding quantity by the average selling price of the held item minus the amount of the field 740.

For example, since the amount of the stock's current price of December 17, 2015, excluding KRW 9,040, which is the average purchase price of the stock, is 8,800, the price fluctuation profit for one week of the remaining balance is retained in the profit by one week. 28,577 won multiplied by the remaining amount of 135 may correspond to the valuation gains of the stock. At this time, the calculation based on the amount shown in FIG. 7 is 211.68 won, which is the amount excluding 8828.32 won, which is the average purchase price of the stocks held at 9,040 won, corresponding to the profit by one week, and the remaining balance is 135 28,576.8 won multiplied by, or 28,577 won, which is the rounded value, can correspond to the valuation gains of the stock.

As described above, the method of managing stock transaction data according to the present invention is provided by displaying the cumulative trading profit, which is the first element of the investment profit, and the valuation gain of the stock, which is the second element of the investment profit, as shown in FIGS. 7 and 8. By doing so, it is possible for the user who holds the stock to grasp the profit/loss information according to each situation at a glance.

At this time, the investment profit corresponds to the sum of the first element and the second element, and can be calculated by subtracting the input amount from the amount multiplied by the remaining balance and the present price.

For example, referring to the data of December 17, 2015 shown in FIG. 7, it can be seen that the cumulative trading profit corresponds to 24,501 won, and the valuation gain of the held item corresponds to 28,577 won. Accordingly, the specific items shown in FIGS. 7 and 8 may correspond to investment profits up to December 17, 2015, totaling 24,501 won and 28,577 won, 53,078 won.

At this time, the value obtained by subtracting 1,167,322 won from the amount multiplied by the residual amount of 135 on December 17, 2015, and 9,040 won is 53,078 won, which is the same value as the investment profit calculated by adding the first element and the second element. You can see that this is calculated.

As described above, by using the method of managing data of the item trading of the first-in-first-out method according to the present invention, accurate investment profit information for a specific item can be provided.

At this time, the average selling price of the held item input in the field 740 may correspond to a value obtained by dividing the sum of the input amount and the cumulative trading profit by the remaining balance. That is, by adding up the cumulative trading profits to the input amount, it is possible to prevent the profits from the trading profits from being included in the valuation gains of the stocks.

*For example, the average selling price of stocks held shortly after the sale on January 19 is 1,601,779 won, which is the sum of the input amount of 1,572,715 won and the accumulated profit and loss of 29,064 until January 19, 2016, divided by the remaining balance of 183. It could correspond to 8753 won.

That is, the unit price of the average selling price of the held item in the field 740 may correspond to the selling price of one week of the held item calculated without taking into account the value input in the cumulative trading profit field 720.

At this time, the existing system holding unit price field 731 shown in FIGS. 7 to 8 may correspond to an average purchase price calculated in accordance with the accounting standard method rather than the first-in-first-out method according to the present invention. In other words, considering only when buying stocks, futures or options, the purchase amount may be divided by the quantity to correspond to the holding price of the evaluated stock.

If using the existing accounting standard method, the investment profit can be calculated as follows.

For example, the gains and losses on the sale on November 19, 2015, from the sale price minus 9,005 minus the existing system holding price of 8,757 won, multiplied by the number of 23 sales, 5,704 won, the purchase fee is 9,005 It can correspond to 4,266 won minus 1,438 won, which is multiplied by the quantity sold by adding 0.5% of the won and 0.2% of the selling fee of 8,757 won.

In addition, the valuation gains for stocks held on November 19, 2015 may correspond to 33,232 won, which is the amount obtained by subtracting the existing system holding unit price of 8,757 won from the current price of 9,005 won. At this time, when obtaining the valuation gains of the stocks in the existing accounting method, it can be confirmed that the purchase average price calculated by the purchase is used as it is, even when the sale occurs. That is, since only the purchase amount at the time of purchase is considered, it can be determined that the gains and losses generated by the sale are included in the calculation of the valuation gains of the stocks.

At this time, it can be seen that the sum of 4,266 won for trading profit calculated by the existing accounting method and 33,232 won for valuation of held items is 37,498 won, which is not the same as the investment profit of November 19, 2015, 37,826. Of course, the difference between the existing method and the present invention in the investment profit calculated on November 19, 2015 by the above example may be as small as 328 won, but this difference if buying and selling for the corresponding item continuously occurs. Can gradually grow and grow. In addition, such a large difference may cause damage in financial transactions such as stocks, futures and options.

Therefore, the present invention can solve the above problems by providing stock transaction data based on a first-in-first-out method.

At this time, the holding unit price described in the holding unit field 730 means the unit unit price per share calculated by taking into account the cumulative trading profit, and is simply held by comparing the average selling price and holding unit price. You can also judge the profit or loss on an item.

9 is a diagram showing an example of an interface screen of an item trading data management apparatus according to the present invention.

Referring to FIG. 9, the interface screen of the stock transaction data management apparatus according to the present invention may correspond to the interface screen provided by the user's smart terminal 910.

That is, the item transaction data provided by the item transaction data management apparatus through the smart terminal 910 may be obtained and output corresponding to FIG. 9.
