Description and application of the ADX indicator in technical analysis

Методы и инструменты анализа

ADX indicator – what kind of indicator and what is the meaning, calculation formula. ADX is used to determine the presence of a trend and its characteristics. The indicator was proposed by the American trader Wells Wilder in 1978. ADX was discussed in detail in his book New Concepts in Technical Trading Systems. One of the features of the indicator is the presence of three curves (+DI, -DI and ADX) on it at the same time. By analyzing these charts, the trader receives signals that allow him to make profitable trades.
Description and application of the ADX indicator in technical analysis In order to successfully work on the exchange, a trader needs to choose or create his own trading system. It consists of several elements, but must include the following parts:

  1. Determination of the market structure.
  2. Looking for opportunities to enter a trade.
  3. Accurate determination of the moment of entry into the transaction.
  4. Calculation of the purpose of the transaction (exit points with profit).
  5. Risk management, including finding the price level at which a losing trade is closed.

Indicator ADX on the chart
The indicator under consideration is not designed to solve all the above tasks at once, but it can be used to determine the structure of market price movements. This concept includes obtaining information about the trend, its direction and strength. Therefore, in the trading system used, in addition to ADX, it is beneficial to use other indicators. For example, it is often used in conjunction with the MACD. An example of a trading system with MACD:
Description and application of the ADX indicator in technical analysis The image below partially describes one of these trading systems. Here is a trend analysis and determination of the trade entry point. ADX values ​​are calculated based on +DI and -DI, ​​which must be predetermined. To perform calculations, the maximum and minimum values ​​of the bars, as well as the closing price, are used. To work with ADX, you must first set the period for which the calculation is carried out. In order to get the indicator value, you need to take the following actions:

  1. It is necessary to compare the maximum value of the current bar and the previous one . If it is greater, then the difference between them becomes the current value. Otherwise, a value of zero is considered. The value thus calculated is assigned to the +DI1 indicator at the point in question. These values ​​will be used to calculate the +DI graph.
  2. You need to calculate the value -DI1 . To get it, you must perform the following steps. It is required to compare the minimum value of the current bar and the same value of the previous one. If the first is less, you need to determine the absolute value of the difference between them. If the condition is not met, the value is assumed to be zero. Based on such data, calculations will be performed, with the help of which a -DI graph will be made.
  3. For each bar, it is necessary to compare the received values ​​+DI and -DI . Whichever is smaller is taken equal to zero. If these values ​​are the same, then both take the value zero.
  4. Now you need to calculate the following three values ​​by absolute value : the difference between the maximum and minimum values ​​of the current bar (High−Low), between the maximum and closing price of the previous bar (High−Close(i-1)), the closing price of the previous bar and the low of the current one ( Low-Close(i-1)). The maximum of these values ​​will be assigned to the TR parameter.
  5. Find +SDI = (+DI1) / TR and -SDI = (-DI1) / TR.
  6. To plot +DI calculate the exponential average of +SDI for a given number of bars . The -DI chart is obtained as the exponential average of -SDI over the selected number of bars.
  7. Further calculations are carried out based on the values ​​of these two graphs. In this case, ADX1 = ((+DI – (-DI)) / (+DI + (-DI))) * 100% .
  8. The indicator value is defined as an exponential average of ADX1 for a given number of bars.

Description and application of the ADX indicator in technical analysis The use of the exponential average is due to the fact that this type of calculation of the average is characterized by relatively less delay. Thus, three lines are built that make up the indicator under consideration. Each of the lines used has its own meaning. Curves +DI and -DI show the strength of the movement up or down, respectively. The ADX line characterizes the strength of the trend without taking into account its direction. All three lines allow the trader to get all the basic information about the trend, which is necessary for making the decision he needs. How to use the ADX indicator correctly:

How to use the ADX indicator, setup, trading strategies

The indicator takes values ​​between 0 and 100. However, in practice it rarely reaches extreme values. It is generally accepted that a value that does not exceed 20 indicates weakness. If the indicator exceeds 60, then we are talking about a strong and dynamic trend. Experienced traders choose the signal level they need based on their experience and knowledge. In the standard case, the Close price is used for calculation, which is not recommended to be changed. Choosing your own option for this makes sense only in cases where the trader has good reasons for this. The duration of the calculation period should be suitable to cover the desired portion of the schedule without causing excessive delay. In most cases, a value of 14 bars is used, which in most cases is set by default.

When to Use

The ADX indicator is designed to be used during trending movements. During the flat, its use will be ineffective. Since its application allows analyzing only the structure of the market, it will be necessary to supplement it with one or more other indicators in such a way that it would be possible to build an effective trading system on their basis. Examples of using the indicator: Indicator
Description and application of the ADX indicator in technical analysis signals are chosen in such a way that a trader can find a trend at its beginning and exit when it weakens. The direction will be prompted by +DI and -DI graphs. If the first one goes higher, then we are talking about an uptrend, otherwise, a downtrend. Its strength is determined by the ADX curve.

Pros and cons of application

The advantage of this indicator is the ability to determine the strength of the trend. This will allow you to enter a trade during the initial stage of the trend and exit it when it ends. The indicator helps the trader assess the relative strength of bulls and bears on the stock exchange, allowing a better understanding of the reasons and prospects for the price movement of the instrument. The disadvantage is the delay associated with the fact that the calculation uses the calculation of average values. If the calculation period is shortened, the response will be faster, but the number of false signals will increase.

Application in different terminals

This indicator is included in the number of standard indicators for most indicators. In the Metatrader terminal, working with it is as follows. Indicator parameters:
Description and application of the ADX indicator in technical analysis In order to get started, you need to select the desired instrument and the appropriate timeframe. Next, you need to perform the following operations:

  1. In the main menu, you need to click on the “Insert” item.
  2. In the menu, select the line “Indicators”. In the submenu go to “Trend”, then to “Average Directional Movement Index”.
  3. After that, a window for entering parameters opens. In it, you need to specify the calculation period, the price at which the calculation will be made. In the standard case, Close is used here, however, if desired, the trader can use other options: Open, High, Max, Min, Median Price, Typical Price or Weight Price.
  4. Next, you can select the type, thickness and color of the graph lines. For the convenience of analysis on the chart, you can set those horizontal levels that the trader considers significant.
  5. By default, the chart will be shown for all used timeframes. If desired, the user can select only some of them.

Description and application of the ADX indicator in technical analysis The possibility of fixing the zero level is provided. If you put a bird in front of this line, when the chart moves, the trader will observe the data starting from this level. Otherwise, only the part where there are curves will be displayed. If the calculation period decreases, the delay will be reduced. However, trends will be shown for a shorter period of time. In this case, the number of signals will increase, but some of them may be false. In order to increase the probability of success, in such cases, you can apply an additional filter that will suggest the most profitable signals.
