Guide to Aroon Indicator Are Calculated?

7 minutes read

The Aroon indicator is a technical analysis tool that helps traders and investors identify trends in the market and anticipate potential price reversals. It includes two lines - Aroon Up and Aroon Down - which are calculated using a specific formula.


To calculate the Aroon Up line, you need to determine the number of periods since the highest high within a given time frame. For example, if you are using a 20-period Aroon indicator, you need to find the number of periods since the highest high in the last 20 periods. The formula for calculating Aroon Up is: ((Number of periods - Number of periods since the highest high) / Number of periods) x 100.


Similarly, to calculate the Aroon Down line, you need to determine the number of periods since the lowest low within the same time frame. Using the 20-period Aroon example, you would find the number of periods since the lowest low in the last 20 periods. The formula for Aroon Down is: ((Number of periods - Number of periods since the lowest low) / Number of periods) x 100.


Both the Aroon Up and Aroon Down lines oscillate between 0 and 100, indicating the strength and direction of the trend. A high value suggests a strong trend, while a low value implies a weak trend.


Traders often look for two key points in the Aroon indicator: 1) when the Aroon Up line crosses above the Aroon Down line, it indicates the start of an uptrend, and 2) when the Aroon Down line crosses above the Aroon Up line, it signals the beginning of a downtrend.


By monitoring the Aroon indicator, traders can gain insights into the current trend's momentum and identify potential buying or selling opportunities. However, it's important to note that the Aroon indicator may not be foolproof and should be used in conjunction with other technical analysis tools for better accuracy in decision-making.

What are the default settings for the Aroon Indicator?

The Aroon Indicator has two components - Aroon Up and Aroon Down. The default settings for both components are as follows:

  1. Aroon Up: Typically, a period of 25 is used. It calculates the number of periods (days, weeks, months, etc.) since the highest high within the chosen period. The Aroon Up line ranges from 0 to 100, with 100 indicating a new high within the period.
  2. Aroon Down: Also commonly set to a period of 25, it calculates the number of periods since the lowest low within the chosen period. Similar to Aroon Up, the Aroon Down line ranges from 0 to 100, with 100 indicating a new low within the period.


These settings are customizable based on the trader's preference or the specific market being analyzed.


How to calculate Aroon Down using the Aroon Indicator?

To calculate the Aroon Down using the Aroon Indicator, follow the steps below:

  1. Determine the number of periods you want to consider for the calculation. This is typically 14 periods, but you can adjust it based on your preference.
  2. Identify the lowest low within the specified number of periods. The low is the lowest price reached during the period. Record the number of periods from the current period to the lowest low as "X."
  3. Calculate the Aroon Down value using the formula: Aroon Down = (X / Number of periods) * 100 For example, if the lowest low occurred 5 periods ago in a 14-period calculation, the Aroon Down would be: Aroon Down = (5 / 14) * 100 = 35.71 This means that the lowest low occurred 35.71% of the interval ago.
  4. Repeat this calculation for each period, updating the "X" value as the lowest low changes.


The Aroon Down value can range from 0 to 100. A higher Aroon Down value indicates a stronger downtrend, while a lower value suggests a weaker or non-existent downtrend.


How to customize the Aroon Indicator parameters?

The Aroon Indicator is a technical analysis tool that helps identify the trend strength and trend reversal points of a particular asset. It consists of two lines: the Aroon-Up line and the Aroon-Down line. Both lines oscillate between 0 and 100, where higher values indicate a stronger trend.


To customize the Aroon Indicator parameters, you can adjust the following:

  1. Lookback Period: This refers to the number of periods considered in calculating the indicator. The default period is usually set to 14, but you can change it to your desired value based on your trading strategy. A smaller period gives more timely signals, while a larger period provides a broader perspective.
  2. Threshold Levels: Aroon can also be customized by setting threshold levels for identifying trend reversal points. The default thresholds are commonly set at 70 and 30, where values above 70 indicate a strong trend, and values below 30 indicate a weak trend or potential trend reversal. You can modify these levels to fit your preferred trading style and the specific asset you are analyzing.
  3. Line Colors and Styles: You can also customize the visual presentation of the Aroon Indicator by changing the line colors and styles. This helps in visually distinguishing between the Aroon-Up and Aroon-Down lines. Different trading platforms or charting software provide options to modify the line color, thickness, and style to your liking.


It's important to note that customizing the parameters of the Aroon Indicator should be aligned with your overall trading strategy and should be tested thoroughly before fully implementing them in your trading decisions.
