Description

Cryptocurrency arbitrage application {Application for cryprocurrency arbitrage}

The present invention relates to virtual currency, and in particular, relates to a technology for buying and selling virtual currency through a virtual currency exchange.

Virtual currency refers to currency that is traded online without real money such as bills or coins, and is also called digital currency or crypto currency. As a representative cryptocurrency, Bitcoin is an example, and in addition, Ripple and Ethereum are well known. Such cryptocurrencies are bought and sold in the same way as stocks through online cryptocurrency exchanges. However, unlike stocks, there are many cases in which virtual currency of the same stock is traded at different prices for each virtual currency exchange.

Korean Patent Publication No. 10-1628007 (announced on June 13, 2016)

An object of the present invention is to provide a method to allow a person holding a virtual currency to generate additional revenue.

According to one aspect, the virtual currency arbitrage application installed and executed on the user's communication terminal includes a bid price check unit that checks the bid price for each virtual currency exchange in real time for the virtual currency of the same item held by the user on different virtual currency exchanges. , A trading and asking price comparison unit that compares the buying and selling prices at different cryptocurrency exchanges checked for the same cryptocurrency, and when the difference between the buying and selling prices is more than a predetermined amount compared to the trading fee, the cryptocurrency trading of the same stock is decided. It may include a trading decision unit, and a trading processing unit for requesting a sale to a cryptocurrency exchange having a high bid price and a cryptocurrency exchange having a low bid price when the trading is determined.

In the trading decision department, the highest bid price for the same cryptocurrency held in one cryptocurrency exchange is higher than the minimum bid price for cryptocurrencies of the same stock held in other cryptocurrency exchanges, but the difference between the highest bid and the lowest bid price is one. The trading can be decided only when the sum of the trading fee for the highest bid price of the virtual currency exchange and the trading fee for the lowest asking price of other virtual currency exchanges is more than a predetermined amount.

The trading unit determines the quantity to be sold and the quantity to be bought equally, but determines the quantity of the transaction to be less than the relatively small order balance among the remaining sales orders of the cryptocurrency exchanges with high bid prices and the remaining purchase orders of the cryptocurrency exchanges with low bids. You can request to sell and request to buy with the determined trading quantity.

The cryptocurrency arbitrage application uses part of the user's deposits of other cryptocurrency exchanges to reach the second deposit set amount higher than the first deposit set amount when the user deposits of other cryptocurrency exchanges are less than the first deposit set amount. It may further include a deposit adjustment unit requesting a transfer to the user account of the exchange.

The cryptocurrency arbitrage application is used when the number of cryptocurrencies of the same item held by a user on a cryptocurrency exchange is less than the set amount of the first cryptocurrency. It may further include a virtual currency holding amount adjustment unit that requests to transfer some of the virtual currency of the same stock held by the user to another virtual currency exchange to reach the user account of the one virtual currency exchange.

The trading processing unit prioritizes the request to sell or request to buy according to the user setting, and may request to buy or request to sell so that the amount of purchase is made by the amount of sale concluded according to the priority request or request of purchase.

According to the disclosure, a user who holds the same cryptocurrency in two or more cryptocurrency exchanges will obtain a profit by maintaining the amount of cryptocurrency in the same amount when there is a difference in the trading price for the cryptocurrency of the same cryptocurrency between exchanges. You will be able to.

In addition, when the price of virtual currency fluctuates sharply, a larger difference in amount may occur due to the difference in time between virtual currency exchanges, in which case a higher margin can be realized.

The above-described and further aspects of the invention will become more apparent through preferred embodiments described with reference to the accompanying drawings. Hereinafter, the present invention will be described in detail so that those skilled in the art can easily understand and reproduce through these examples.

1 is a block diagram of a virtual currency arbitrage trading system according to an embodiment. The cryptocurrency arbitrage trading system includes two or more different cryptocurrency exchange servers 100 and user terminals 200. The virtual currency exchange servers 100 are servers for virtual currency transactions operated by different operators. For reference, as domestic cryptocurrency exchanges, Bithumb, Coinone, Corbit, and Upbit are well known. In one embodiment, the virtual currency exchange servers 100 provide an open API (Open Application Programming Interface).

The user terminal 200 is a communication terminal used by a user, and is a terminal capable of downloading and installing and executing an application from an app store. Such a user terminal 200 may be a smart phone. The user may use the user terminal 200 to sign up for each member of the server 100 of different virtual currency exchanges and create a user account for virtual currency transaction to trade virtual currency. Although not shown in FIG. 1, a dedicated virtual currency trading application for each virtual currency exchange may be installed and executed on the user terminal 200, and the user accesses the virtual currency exchange server 100 through such an application to Can trade.

As shown in FIG. 1, the user terminal 200 has a virtual currency arbitrage application (hereinafter referred to as a “arbitrage application”) 300 installed and executed. Arbitrage trading app 300 requests a sale to a cryptocurrency exchange with a higher transaction price when there is a difference in the transaction price for the cryptocurrency of the same stock held by the user on different cryptocurrency exchanges 100 and the transaction price is With low cryptocurrency exchanges, arbitrage trading is conducted by requesting a buy.

Meanwhile, the user terminal 200 can communicate data with the virtual currency exchange server 100 through a communication network, where the communication network may mean a complex network including one or two or more different networks. For example, a communication network may mean a complex network in which a mobile communication network and a block chain network are mixed. In addition, the arbitrage transaction app 300 may be an application recorded on a computer-readable recording medium (or a non-transitory storage medium).

2 is a block diagram of a virtual currency arbitrage transaction application installed and executed in a user terminal according to an embodiment, and FIG. 3 is a reference diagram for explaining a virtual currency arbitrage transaction. As shown in Fig. 2, the arbitrage transaction app 300 may include a bid price check unit 310, a bid price comparison unit 320, a sale decision unit 330, and a sale processing unit 340, and deposit At least one of the adjustment unit 350 and the virtual currency holding amount adjustment unit 360 may be further included. In fact, the configurations included in the arbitrage transaction app 300 are all functional configurations that can be implemented in software. That is, the arbitrage trading app 300 may perform a trading bid check function, a trading bid comparison function, a trading decision decision function, and a trading processing function, and may further perform at least one of a deposit adjustment function and a virtual currency holding amount adjustment function. have.

Before describing the configurations illustrated in FIG. 2, some of FIG. 3 will be described. The user has a user account on the first virtual currency exchange server (first exchange server) 100-1 and the second virtual currency exchange server (second exchange server) 100-2, respectively. Each user account may include a deposit account and a virtual currency account. Looking at the user account of the first exchange, the user has 1,000 A cryptocurrency (A coin) and 15,000,000 won as a deposit (balance). And looking at the user account of the second exchange, the user also has 1,000 A cryptocurrencies in the second exchange, and has a balance of 6,000,000 won. In other words, the user has the same cryptocurrency in multiple exchange servers. For reference, it has been described that the deposit, which is a currency instrument for virtual currency transactions, is in won, but it is of course possible that it can be a currency other than the won. And the means of currency can be either legal currency or non-legal currency. In the latter case, the means of currency for trading cryptocurrency may also be cryptocurrency, such as the well-known tether.

Returning to FIG. 2 again, the bid price check unit 310 checks in real time the trading bid price for the virtual currency of the same item held by the user on two or more different virtual currency exchange servers 100. For example, as shown in FIG. 3, when a user holds A cryptocurrency in each of the first exchange and the second exchange, the transaction price check unit 310 is a cryptocurrency A traded in the first exchange. Check the bid price (a) and the bid price (b) of the virtual currency A traded on the second exchange. In one embodiment, the trading and asking price check unit 310 is the minimum asking price (a1) and the highest bid price (a2) for virtual currency A at the first exchange, and the minimum selling price for virtual currency A at the second exchange. Check the ask price (b1) and the highest bid price (b2). The bid price check unit 310 may check the bid price of virtual currency A in real time through the open API of the first exchange server 100-1 and the open API of the second exchange server 100-2. Alternatively, the bid price check unit 310 is linked with the virtual currency trading app for the first exchange and the virtual currency trading app for the second exchange, and the bid price for virtual currency A at the first exchange and the second exchange. You can also check in real time.

The buying and selling price comparison unit 320 compares the buying and selling prices checked in real time by the buying and selling price checker 310. That is, the bid price (a) of the virtual currency A traded on the first exchange is compared with the bid price (b) of the virtual currency A traded on the second exchange. In one embodiment, the trading and asking price comparison unit 320 compares the minimum asking price and the highest bid price. For example, the buying and selling price comparison unit 320 compares the lowest bid price (a1) and the highest bid price (b2) of virtual currency A, and compares the highest bid price (a2) and the lowest bid price (b1).

As a result of the comparison of the bid price comparison unit 320, the trading decision unit 330 determines the bid price (a) of the virtual currency A traded on the first virtual currency exchange and the bid price (a) of the virtual currency A traded on the second virtual currency exchange ( If the difference in b) is more than a predetermined amount compared to the trading fee, the transaction of virtual currency A is decided. In one embodiment, the trading decision unit 330 has the highest bid price (b2) higher than the lowest bid price (a1), but the difference between the highest bid price (b2) and the lowest bid price (a1) is the highest bid price (b2). If the sum of the trading fee for) and the trading fee for the minimum ask price (a1) is more than a predetermined amount, the transaction is decided. In addition, the highest bid price (a2) is higher than the minimum bid price (b1), but the difference between the highest bid price (a2) and the lowest bid price (b1) is the trading commission and the minimum asking price (b1) for the highest bid price (a2). Even if it is more than a predetermined amount than the sum of the trading fees for ), the trading is decided. Here, the predetermined amount may be set as a default or may be changed by the user. Hereinafter, for convenience of explanation, the predetermined amount is referred to as 10 won.

3, the minimum bid price (a1) for cryptocurrency A at the first exchange is 23,670 won, and the highest bid price (b2) for cryptocurrency A at the second exchange is 23,790 won. That is, the highest bid price (b2) is higher than the minimum bid price (a1), and the difference is KRW 120. And the trading fee for the minimum bid price (a1) of virtual currency A at the first exchange is 23,670 won × 0.05% = 1.183 won, and the trading fee for the highest bid price (b2) of virtual currency A at the second exchange is 23,790 KRW × 0.05% = KRW 1.189, and the total trading fee is KRW 2.372. The difference of 120 won is 117.628 won more than the total trading fee of 2.372 won, which is more than a predetermined amount of 10 won, and the trading decision unit 330 decides to buy and sell cryptocurrency A.

When the trading is determined, the trading processing unit 340 requests the sale to a cryptocurrency exchange with a high bid and ask price, and requests the purchase to a cryptocurrency exchange with a low bid and bid price. For example, as shown in FIG. 3, when the highest bid price (b2) is higher than the minimum bid price (a1), the trading processing unit 340 requests the sale of virtual currency A to the second exchange, and A to the first exchange. Request the purchase of virtual currency. The trading processing unit 340 may directly request a sale/buy from the first exchange server 100-1 and the second exchange server 100-2, or a virtual currency trading app dedicated to the first exchange and a second exchange It is also possible to request a sell/buy to the first exchange server 100-1 and the second exchange server 100-2 through the virtual currency trading app of.

In one embodiment, the trading processing unit 340 determines the quantity to be sold and the quantity to be bought before making the request to sell and the quantity to be bought, and determine the quantity to be sold and the quantity to be bought equally. This is to ensure that the user's A cryptocurrency holdings are maintained, while only gaining transaction profit. In one embodiment, the trading processing unit 340 determines the trading quantity to be less than a relatively small order balance among the lowest order remaining amount of a cryptocurrency exchange with a high quotation price and the remaining amount of the highest purchase order of a cryptocurrency exchange having a low quotation price. . For example, as shown in FIG. 3, when the order balance of the highest bid and ask price (b2) is 100 and the order balance of the minimum bid and ask price (a1) is 2,300, the trading processing unit 340 uses 100 or less. The oversold quantity is determined equally. In consideration of the fact that the order remaining amount may change rapidly in real time, the trading processing unit 340 may determine a quantity excluding a certain ratio or a quantity excluding a certain quantity from 100, which is a relatively small order balance, as the buy quantity and the sell quantity. .

For convenience of explanation, it is assumed that the trading quantity is determined to be 100. The trading processing unit 340 requests the first exchange to purchase 100 A cryptocurrencies, and requests the second exchange to sell 100 A cryptocurrencies. Accordingly, the first exchange server 100-1 and the second exchange server 100-2 perform trading. When all the transactions are concluded, it means that the user buys A cryptocurrency for 23,670 won and sells it for 23,790 won, resulting in a trading profit of 12,000 won. In addition, the trading fee at Exchange A is 2,367,000 × 0.05% = 1,183 KRW, and the trading fee at Exchange B is 2,379,000 × 0.05% = 1,189 KRW, and the total trading fee is 2,373 KRW. Therefore, the user gets 9,628 won as the final revenue, minus 2,372 won from 12,000 won. And, of course, after such arbitrage transaction, the user account of the first exchange and the user account of the second exchange are updated as shown at the bottom of FIG. 3.

When the arbitrage transaction is made according to the above, the user's deposit and the amount of cryptocurrency A in the first exchange and the user deposit and the amount of cryptocurrency A in the second exchange fluctuate. That is, in the first exchange server 100-1 where the purchase was made, the user deposit decreases and the amount of cryptocurrency A holding is increased, and in the second exchange server 100-2 where the sale is made, the user deposit increases and the amount of virtual currency A is decreased. do. If such arbitrage trading is repeated over and over again, it is possible to achieve a balance between the deposit and the amount of cryptocurrency holdings due to similar purchases and sales at the 1st and 2nd exchanges, but there are many purchases at the 1st exchange and a lot of sales at the 2nd exchange. When this occurs, deposits are insufficient in the first exchange and virtual currency is insufficient in the second exchange, making arbitrage trading as described above impossible.

In order to prevent the arbitrage transaction from becoming impossible, the arbitrage transaction app 300 may further include a deposit adjustment unit 350 and/or a virtual currency holding amount adjustment unit 360. When the transaction processing unit 340 requests a purchase from the first exchange server 100-1 and the purchase is made, the user's deposit of the first exchange decreases, and the deposit adjustment unit 350 receives the first transaction request from the transaction processing unit 340. Check the user deposit of the exchange to see if it is less than the set amount of the first deposit. If the amount of the first deposit is less than the set amount, the deposit adjustment unit 350 transfers a portion of the user deposit registered in the second exchange server 100-2 so that the user deposit reaches the second deposit set amount higher than the first deposit set amount. Request a transfer to the user account registered in 100-1). For example, the deposit adjustment unit 350 requests a transfer while transmitting the user deposit account address information registered in the first exchange server 100-1 and the transfer request amount to the second exchange server 100-2. Accordingly, the deposit is transferred from the user account of the second exchange server 100-2 to the user account of the first exchange server 100-1.

In addition, when the transaction processing unit 340 requests the sale to the second exchange server 100-2 and the sale is made, the holding amount of virtual currency A decreases, and the virtual currency holding amount adjustment unit 360 is the user of the second exchange. Check the holding amount of to check whether it is less than the set amount of the first virtual currency. If the amount of cryptocurrency is less than the set amount of the first cryptocurrency, the cryptocurrency holding amount adjustment unit 360 registers with the first exchange server 100-1 so that the cryptocurrency A reserves reach the second cryptocurrency set amount higher than the first cryptocurrency set amount. A part of the amount of virtual currency of the user is transferred to a user account registered in the second exchange server 100-2. For example, the virtual currency holding amount adjustment unit 360 transmits the user virtual currency account address information registered in the second exchange server 100-2 and the A virtual currency transfer request quantity to the first exchange server 100-1. Request a transfer. Accordingly, virtual currency transfer is made from the user account of the first exchange server 100-1 to the user account of the second exchange server 100-2.

In addition, as described above, the deposit adjustment unit 350 may not request a deposit transfer to the second exchange server 100-2, but may notify the user that the deposit adjustment is necessary. Similarly, as described above, the virtual currency holding amount adjusting unit 360 may not request a virtual currency transfer to the first exchange server 100-1, but may notify the user that the virtual currency holding amount needs to be adjusted. Alternatively, the virtual currency holding amount adjustment unit 360 may request a virtual currency transfer to the first exchange server 100-1, and the deposit adjustment unit 350 may notify the user that the deposit adjustment is necessary, and vice versa. It is also possible. In addition, the notification method may be performed through sound and/or notification message display.

Meanwhile, the trading processing unit 340 may first request any one of a sell request and a buy request and then perform the remaining request, which may be according to a user's preset setting. For example, the trading processing unit 340 provides a trading option function that enables the user to set which of the selling and buying priority is given. The user can choose to sell or buy priority through the trading option function.For example, if the cryptocurrency is determined to decline in the long term, it is set to buy first, and if it is determined to rise, it is set to sell first. . In addition, the trading processing unit 340 prioritizes the request to sell or the request to buy according to the user setting. When the sale is set as priority, the trading processing unit 340 first performs the sale request and then performs the purchase request so that the purchase is made by the amount of sale concluded according to the priority sale request. Conversely, in the case where the purchase priority is set, the trading processing unit 340 first performs the purchase request and then performs the sale request so that the sale is made by the amount of purchase concluded according to the priority purchase request. The above characteristic is to take into account the case that unplanned additional purchases or additional sales may occur if the requested quantity is not concluded at the time of requesting for sale or purchase, and is intended to minimize the loss or risk caused by additional purchases or additional sales.

4 is a flowchart of a virtual currency arbitrage trading method according to an embodiment. First, it is premised that the user distributes the transaction amount to two or more exchanges, and purchases more than a predetermined amount of virtual currency of the same stock. The user terminal 200 checks in real time the buying and selling price of the virtual currency of the same item held by the user on two or more different virtual currency exchange servers 100 (S100). Referring to FIG. 3, the user terminal 200 includes a bid price (a) of virtual currency A traded in the first exchange server 100-1 and A virtual currency traded in the second exchange server 100-2. Check the buying and selling price (b) of the currency. In one embodiment, the trading and asking price check unit 310 is the minimum asking price (a1) and the highest bid price (a2) for virtual currency A at the first exchange, and the minimum selling price for virtual currency A at the second exchange. Check the ask price (b1) and the highest bid price (b2).

The user terminal 200 compares the bid price (a) and the bid price (b) of the virtual currency A checked in real time (S200). In S200, the user terminal 200 compares the minimum bid price (a1) and the highest bid price (b2) of the virtual currency A, and compares the highest bid price (a2) and the minimum bid price (b1). The user terminal 200 determines whether to buy or sell virtual currency A according to the comparison result (S300). In S300, the user terminal 200 has the highest bid price (b2) higher than the lowest bid price (a1), but the difference between the highest bid price (b2) and the lowest bid price (a1) is trading at the highest bid price (b2). It is decided to buy and sell cryptocurrency A if it is more than a predetermined amount than the sum of the commission and the trading fee for the minimum asking price (a1). When the trading is determined, the trading processing unit 340 requests the first exchange server 100-1 to purchase the A cryptocurrency, and the second exchange server 100-2 to request the second exchange server 100-2 to sell the A cryptocurrency (S400). . In S400, the user terminal 200 may determine the quantity to be sold and the quantity to be purchased equally as described above. In addition, in S400, the user terminal 200 may prioritize any one of the sell request and the buy request and then perform the remaining request, as described above.

Thereafter, the user terminal 200 checks whether the user deposit of the first exchange server 100-1 that purchased the virtual currency A is less than the set amount of the first deposit (S500), and if it is less than the first exchange, as described above. The deposit is adjusted so that the user deposit of the server 100-1 reaches the set amount of the second deposit (S600). As another example, in S600, the user terminal 200 does not adjust the deposit by requesting a transfer of the deposit to the exchange, but informs the user that the deposit adjustment is necessary so that the user adjusts the deposit.

In addition, the user terminal 200 checks whether the amount of virtual currency A of the user registered in the second exchange server 100-2 that sold the virtual currency A is less than the set amount of the first virtual currency (S700), and if it is less than As described above, the virtual currency holding amount of the user registered in the second exchange server 100-2 is adjusted so that the holding amount of virtual currency A is equal to or greater than the set amount of the second virtual currency (S800). As another example, in S600, the user terminal 200 does not request a virtual currency transfer from an exchange to adjust the virtual currency holding amount, but informs the user that the virtual currency holding amount needs to be adjusted, so that the user adjusts the virtual currency holding amount.

Meanwhile, the above virtual currency arbitrage trading method can be written with a computer program. Codes and/or code segments constituting such a program can be easily inferred by a computer programmer in the art. In addition, such a program is stored in a computer readable media, and is read and executed by a PC, thereby implementing a virtual currency arbitrage method. Such information storage media include magnetic recording media, optical recording media, and the like.
