1 illustrates a cryptocurrency trading system 100 according to various embodiments of the present disclosure.

The cryptocurrency trading system 100 indicates a system that provides an environment in which service users such as cryptocurrency investors or trading service providers can trade cryptocurrency. According to the cryptocurrency trading system 100, investors can buy or sell cryptocurrency through a cryptocurrency exchange, and the cryptocurrency exchange can provide a cryptocurrency trading service and make profits through fees. In addition, the investment information provider may provide investment information related to cryptocurrency trading to investors or transaction service providers. According to an embodiment of the present disclosure, the cryptocurrency trading system 100 may include a terminal 101, an exchange server 103, an investment information providing device 105, and a network 107.

The terminal 101 indicates an electronic device used by a service user who trades cryptocurrency. The terminal 101 is an electronic device used by sellers or buyers of cryptocurrencies to trade cryptocurrencies, and a service user can use the terminal 101 to access the exchange server 103 and through the exchange server 103 Cryptocurrency trading service is available. According to an embodiment of the present disclosure, the terminal 101 may include a fixed terminal implemented as a computer device or a mobile terminal. Specifically, the terminal 101 may indicate a smart phone, a mobile phone, a navigation device, a computer, a laptop computer, a digital broadcasting terminal, personal digital assistants (PDA), a portable multimedia player (PMP), and a tablet PC. In addition, the terminal 101 may communicate with at least one of the exchange server 103 and the investment information providing device 105 through the network 107 . A specific configuration of the terminal 101 is described in detail in FIG. 2 .

The exchange server 103 provides a platform for exchanging or trading at least one type of cryptocurrency and instructs a server device of an exchange that obtains fees as revenue. According to one example, the exchange server 103 serves as a platform for buying and selling virtual currency, provides a currency exchange service between legal currency and cryptocurrency, or exchanges cryptocurrency at a market price or a fixed price through a web order window. It can perform a distributing function. In addition, the exchange server 103 may be implemented as a computer capable of accessing a remote server or terminal through the network 107 .

The investment information providing device 105 indicates an electronic device used by the investment information provider. The investment information providing device 105 may perform a function of generating investment information related to liquidity of cryptocurrency and providing the investment information to service users. Specifically, the investment information providing device 105 may receive transaction information about transaction details for each cryptocurrency item from the exchange server 103 and calculate indicators related to liquidity using the transaction information. Thereafter, the investment information providing device 105 may assist in stable cryptocurrency transactions by providing the service user with investment information including the calculated indicators.

As shown in FIG. 1 , components of the cryptocurrency trading system 100 may be connected through a network 107 . According to an embodiment of the present disclosure, the network 107 refers to a connection structure capable of exchanging information between nodes such as a plurality of terminals and servers, and an example of such a network includes RF, 3GPP (3rd generation partnership project) network, LTE (long term evolution) network, 5GPP (5rd generation partnership project) network, WIMAX (world interoperability for microwave access) network, Internet, LAN (local area network), Wireless LAN (wireless local area) network), WAN (wide area network), PAN (personal area network), Bluetooth (bluetooth) network, NFC network, satellite broadcasting network, analog broadcasting network, digital multimedia broadcasting (DMB) network, etc., but are not limited thereto. .

In the digital asset market, sell and buy orders are formed by the selling price desired by the seller and buyer, respectively, and the market price is formed as a result of mutual agreement. The more active the market is, the more buy and sell orders are placed at a price close to the agreed upon price, and the transaction is concluded at a price with a small difference from the market price. A transaction may be concluded at an out-of-price price. Using this point, there have been various attempts to make it appear as if actual market transactions are not being actively conducted, and these attempts have caused unexpected losses to service users. In particular, most of the abnormal attempts are made by abusing the fact that cryptocurrency exchanges only display the price fluctuation range and trading volume of cryptocurrency, and it is difficult for service users to identify abnormal attempts until they continuously observe changes in quotes. . In response to this, the investment information providing device 105 according to the present disclosure measures the change in quotes submitted in the market and identifies and digitizes the normal range of price volatility that can occur based on the market trading volume, thereby providing investment information to service users. It aims to provide

In the case of quotes submitted in the cryptocurrency trading market, which are formed only through normal transactions, they show various patterns during the contracting process. Specifically, in the case of execution by market order, if the first quantity of the first quotation executed is greater than the trading volume, the quotation equal to the first quantity minus the trading volume remains. In the case of execution by limit order, if the first quantity is smaller than the trading volume and the limit price is not the price at which the second quotation will be executed, the quotation equal to the trading volume minus the 1st quantity remains as the opposite quotation, and the limit price is up to the quotation price equal to or greater than the second quotation. In the case of the price to be concluded, the number of bids equal to the difference between the second bid price and the second bid price remains. In other words, a single execution order causes a change in the quote price along with the transaction volume. If this is quantified, it is predicted how many quotes submitted for the order corresponding to the average transaction volume will be executed and how much the quote price will change. It can be. Using this, the investment information providing device 105 according to the present disclosure may calculate an index through average calculation and deviation calculation with respect to the changeable range measured during a specific time interval in consideration of the trading volume and the fluctuation range.

The investment information providing device 105 may generate an ideal indicator by determining a price change and calculating a deviation for each of the index constituent stocks when a transaction occurs according to all transactions. However, anomalous indicators are prone to error in the presence of unusual market disruptive behavior. In order to consider the quotation change for abnormal behavior, the investment information providing device 105 calculates the deviation by adding possible price fluctuations, including the quantity canceled after submitting the quotation within the price fluctuation range together with the price change when the transaction occurs, A blink reflection index can be created. Alternatively, the investment information providing device 105 may generate a general index by measuring bid prices for each price fluctuation range multiple times and calculating a difference between the effective bid price and the current price within the price fluctuation range.

Since the generated indicators use a method of setting the baseline for the next interval based on the statistics of the previous interval, abnormal behaviors that deviate from the average value are reflected in the form of noise. That is, if a deviation for a volatility that is too large or too small is observed, the indicator is immediately reflected in the form of noise.

In addition, since the index is an index that derives a deviation of the measurement results of each section, more accurate results are derived as the number of samples increases. Therefore, the reliability of the index may increase in the case where a plurality of measured results are adopted in the case where a plurality of nodes form a network to generate and accumulate results respectively.

The investment information providing device 105 may extract index trade data suitable for current market conditions from trade information and provide liquidity indicators related to trading volume and volatility to investors in real time. In addition, the investment information providing device 105 may protect the investor by notifying the investor when it is identified that an abnormal situation has occurred through liquidity-related investment indicator analysis. Hereinafter, a specific method for the investment information providing device 105 to calculate the liquidity index is exemplified.
