Introduction
The Aroon indicator, which is widely used by traders to identify trends and trend changes in the price of an asset, was created by Tushar Chande in 1995. Chande is a well-known technical analyst and author of several books on trading and technical analysis. The indicator’s name is derived from the Sanskrit word for “dawn’s early light” or “the first light of day,” reflecting its purpose of identifying the beginning of a new trend.
The Aroon indicator comprises two lines, the Aroon up line and the Aroon down line, which measure the strength of uptrends and downtrends, respectively. The indicator is based on the concept that the price of an asset reaches its highest point during an uptrend and its lowest point during a downtrend. The Aroon up line measures the number of periods since the highest high of the asset was reached, while the Aroon down line measures the number of periods since the lowest low of the asset was reached.

The Aroon indicator is plotted on a scale of 0 to 100, with a value of 100 indicating a strong uptrend and a value of 0 indicating a strong downtrend. Traders can use the Aroon indicator to identify potential buy or sell signals. For example, if the Aroon up line crosses above the Aroon down line, it suggests that a new uptrend may be starting, and it could be a signal to buy. Conversely, if the Aroon down line crosses above the Aroon up line, it suggests that a new downtrend may be starting, and it could be a signal to sell.
However, it is important to note that the Aroon indicator is not always accurate and should be used in conjunction with other technical analysis tools to confirm potential buy or sell signals. Moreover, it may be more effective in identifying trends in longer-term charts rather than short-term charts.

Computing the Aroon Indicator
The Aroon indicator is calculated using two formulas: one for the Aroon up line and one for the Aroon down line.
The formulas to compute are:
Aroon Up = ((Period - Periods Since the Highest High)/Period) x 100
Aroon Down = ((Period - Periods Since the Lowest Low)/Period) x 100
Where:
- “Period” is the number of periods (usually days) that you want to use for the Aroon calculation.
- “Periods Since the Highest High” is the number of periods since the highest high of the asset was reached within the Period.
- “Periods Since the Lowest Low” is the number of periods since the lowest low of the asset was reached within the Period.
In order to calculate the Aroon Up, you need to first determine the number of periods since the asset’s highest high within the period. Subtract that number from the period, divide the result by the period, and then multiply by 100 to get a percentage.
Similarly, to calculate the Aroon Down, you need to determine the number of periods since the asset’s lowest low within the period. Subtract that number from the period, divide the result by the period, and then multiply by 100 to get a percentage.
Once you have calculated the Aroon Up and Aroon Down, you can plot them on a chart and use them to identify trends and potential buy or sell signals. It is important to keep in mind that the Aroon indicator is most effective when used alongside other technical analysis tools to confirm potential buy or sell signals.
