The Aroon Indicator (often referred to as Aroon Up Down) is a range bound, technical indicator that is actually a set of two separate measurements designed to measure how many periods have passed since price has recorded an n-period high or low with “n” being a number of periods set at the trader’s discretion. For example a 14 Day Aroon-Up will take the number of days since price last recorded a 14 day high and then calculate a number between 0 and 100. A 14 Day Aroon-Down will do the same thing except is will calculate a number based of the number of days since a 14 day low. This number is intended to quantify the strength of a trend (if there is one). The closer the number is to 100, the stronger the trend. Aroon is not only good at identifying trends, it is also a useful tool for identifying periods of consolidation.
