Aroon Indicator & Oscillator

In 1995 Tushar Chande created an indicator named Arun to tell whether a stock is trending or not and how strong that trend is. Arun is a Sanskrit word which means the morning aura or the first ray. Chande chose the name because through it he wanted to mark the beginning of a new trend. The Arun indicator measures the period over which the price has made a high or low. There are two types of indicators – Aroon-Up and Aroon-Down.

The 25 day arun up measures the days from the 25 day high to the present. Similarly, 25 days Arun Down counts the days from the 25 days low till now. The Aroon indicator differs from a regular Momentum Oscillator in that it looks at time in terms of price, while other momentum oscillators look at price in terms of time. The Aroon indicator can be used to identify new trends and consolidation, define periods of correction, and anticipate reversals.

Arun Oscillator

The Aroon Oscillator is an extension of the Aroon indicator. Aroon measures the difference between the oscillator and the aroon up and down and shows it as an oscillator. This oscillator rotates between -100 to 100 and 0 is its focal point. The Aroon Oscillator is shown in the chart below.

An oscillator above 0 means that Aroon Up is greater than Aroon Down, meaning that prices have been making new highs more frequently in the past few days. Conversely, being below 0 means that Aroon Down is greater than Aroon Up, meaning prices are making more new lows than new highs.

As you can see the Aroon Oscillator will usually be either positive or negative. Because of this it becomes easy to read this oscillator. Time and price both show bullishness when this indicator is positive and bearish when this indicator is negative. At what number this indicator is positive and negative, it shows how strong the trend is. For example, above 50 means there is strong bullishness, while below -50 means that there is strength in the bearish.
