Aroon Indicator (Formula, Strategy, Best Setting & PDF)

Aroon Indicator

Aroon indicator was developed by Tushar Chande to determine the price trend of a stock and also to understand how strong is the trend of the stock price. There are two lines in the indicator. The green line shows uptrend and the red line shows the downtrend. The green line is known as Aroon Up and the red line is known as Aroon Down. When any of the lines touch 100, it indicates the trend is going to reverse. Similarly, when any line touches zero it also shows the imminent trend reversal. A combined reading of up and down line gives the real market trend.

Aroon Indicator FAQ

What is Aroon Indicator?

Aroon was developed by Tushar Chande. This indicator identifies an uptrend or a downtrend. And just like the ADX/DMS, this indicator also identifies how strong the trend is.

How do you calculate Aroon oscillator?

There are two lines in this oscillator. One is Aroon Up and another is Aroon Down. Aroon Up us calculated by the number of periods minus the number of periods since the highest high divided by the number of periods multiplied by 100. Similarly, the Aroon Down is calculated by the number of periods minus the number of periods since the lowest low divided by the number of periods multiplied by 100. Check the formula section above on this page.

What is the best setting for the Aroon Indicator?

In Zerodha Kite or other trading terminals, the default setting for Aroon is 14-period. But I have checked that changing this default to 25 minimizes the whipsaw to a large extent. Check the attached image. Remember you can play with the parameters and tweak the defaults as per your need.
