This overview is devoted to an oscillator called Aroon. If helps detect the current trend and find entry points to the market.

Description of Aroon

Aroon is a trading indicator that belongs to the group of normalised oscillators. It was designed by a trader of Indian origin Tushar Chande in 1995 for assessing the market trend, whether it is strong or weak.

As long as Chande was born in India, the name of the indicator belongs to Indian mythology: in Sanskrit, Aroon means Charioteer of the Sun God or Light of the Morning Dawn.

Aroon contains of two main lines: Aroon-Up and Aroon-Down.

  • The Aroon-Up line is blue; it assesses from 0 to 100% the ratio of the number of periods (weeks, days, or hours, depending on the chosen timeframe) that have passed since the high appeared on the chart — and the period of the indicator. The less time passes since the last high appeared on the chart, the higher the Aroon-Up line goes.
  • The Aroon-Down line (red color) assesses from 0 to 100% the ratio of the number of periods (weeks, days, or hours, depending on the chosen timeframe) that have passed since the low appeared on the chart — and the period of the indicator. The less time passes since the last low appeared on the chart, the higher the Aroon-Down line goes.

The indicator is calculated in a separate window under the price chart. Through levels 30% and 70%, lines are drawn that help detect the current trend. If Aroon-Up goes above 70%, and Aroon-Down drops below 30%, this means the trend is ascending, bulls are dominating.

And vice versa: when Aroon-Up is below 30% and Aroon-Down rises above 70%, the trend is descending, and bears are in control.
