Technical analysis is one of the techniques for analyzing and predicting financial markets including the stock market. Price graphs (charts) are mainly used for technical analysis.
Since the technical analysis has a highly subjective nature. Most market participants have different experiences and skill acquisition levels, the results are different.
The technical analysis predicts how future prices will move based on several assumptions and past and present price movements. The validity of the technical analysis depends on past market experience.
However, stock investors often fail to invest in stocks due to lack of information and lack of systematic analysis when using the typical stock trading system.
Therefore, a chart analysis method that leads to successful trading is required.
The technology that forms the background of the invention has been written to facilitate a better understanding of the present invention. It should not be understood that the matters described in the technology that forms the background of the invention exist as the related art.

Referring to
Hereinafter, for convenience of description, a support line, which is one of the various parameter values, will be described as an example. The plurality of different users may be user A, user B, and user C.
Referring to
The received values may be collected and stored, and transmitted to the chart analysis server 300. In this case, these values may be values collected by receiving consent from the user for collection and third-party use and provision.
When the users change the support line, the user device 100 may obtain consent from the user to reflect the changed value. the parameter values may be collected at regular time intervals to reflect the changed value, and the final value obtained by averaging the values before and after the change may be collected.
When the users delete the support line or withdraw the consent for collection and third-party use and provision, the collected values may be discarded. The analysis information including the corresponding values may be discarded.
The method for collecting and discarding stock items, technical analysis indicators, and parameter values described in the presented embodiment are not limited to the above-described contents.
The chart analysis server 300 determines a weights for each of the plurality of different users using the received parameter values (S410). First, to determine the weights, the chart analysis server 300 may substitute the profitability or error rates with the weights using at least one of the function or algorithm that makes the sum of the weights of each of the plurality of different users equal to 1.
In the present disclosure, the profitability may refer to a ratio of profitable trade in the past trading records of the users, and the error rate may refer to the accuracy of chart analysis parameters set in the past. In this case, the error rate may include at least one of error rates for the same type of parameter values as the received parameter values for the one type stock, or error rates including a different type of parameter values from the received parameter values.
For example, the chart analysis server 300 may use a Softmax function to make the sum of the weights of each of the plurality of different users equal to 1.
The input value may be the ratio of profitable trade calculated from the past trading records. The output value may be derived as a value between 0 and 1 for each user so that the sum becomes 1. With respect to the method for assigning weights to profitability, the chart analysis server 300 may assign higher weighs to more profitable users. Referring to
With respect to the method for assigning the weights to the accuracy of the past chart analysis, the chart analysis server 300 may assign a higher weight to the more accurate the chart analysis parameter values set in the past. In other words, the smaller the error rate, the higher the weight may be assigned. Hereinafter, for convenience of description, the support line, which is one of the various parameter values, will be described as an example.
When the current stock price is in a downward trend at the $120 level, referring to
When these past records are averaged by user, the average error rate by user is obtained. The chart analysis server 300 may assign higher weight to a user with a smaller error rate. For example, the Softmax Function may be used using (100−error rate) as the function input value.
In various embodiments, the chart analysis server 300 may sum the accuracy of different technical analysis indicators, or may use only the accuracy of the currently handled technical analysis indicator. In other words, when deriving the signal for the support line, the chart analysis server 300 may determine the weight by considering only the error rates of the users' past support line indicators, or may determine the weight by considering the error rates of other technical analysis indicators such as MACD and the support/resistance lines. In the latter case, the chart analysis server 300 may additionally perform a step of standardizing the error of each technical analysis indicator. This may be because the unit of ‘error’ is different for each technical analysis indicator.
Referring to
For example, the chart analysis server 300 may normalized the error rate of various technical analysis indicators between 0 and 1 through Equation 1.
The chart analysis server 300 may the error rate so that the average is 0 and the standard deviation is 1 through Equation 2.
The chart analysis server 300 may determine optimum parameter value using the parameter values and weights obtained from the plurality of users (S420).
Specifically, the optimum parameter values may be determined by adding the weights substituted in the above process and the parameter values for the support lines collected from the users A, B, and C.
The function or algorithm for substituting the profitability and error rate into the weights and the method for standardizing errors are not limited to the above-described contents.
When the user device 200 requests chart analysis for a stock item, the chart analysis server may display the interface screen that provides the determined optimum parameter values to the user (S430).
The following will describe the interface screen related to the chart analysis with reference to
Referring to
Here, the graphic object displayed in the second area may include selection items such as “total, return rate of 80% or higher, 60% or higher”.
The graphic object displayed in the third area may include selection items such as “support/resistance lines, RSI, and MACD” and represent the recommended parameter as an indicator, and may be represented as a chart type. For example, a chart for the recommended parameter value may be provided in the form of a candle, line, bar, flow, etc.
The graphic object displayed in the fourth area may be an icon or image that notifies the trading signal for the corresponding item according to the recommended parameter value.
In various embodiments, when users are determined based on the profitability, the graphic object may be displayed to represent only the histogram of the determined users. For example, when a user profitability of 80% or higher is selected in the second area 612, a histogram representing the number of users compared to parameter values for users with the user profitability of 80% or higher may be displayed.
The configuration of the interface screen, the user profitability, and the technical analysis indicators described in the presented embodiment are not limited to the above-described contents, and the objects constituting each interface screen may be configured in various ways.
