A trend-following indicator used to gauge the strength of a current trend and the likelihood that it will continue. The Aroon indicator system consists of three lines: Aroon Up, Aroon Down, and the Aroon Oscillator which reflects the difference between the two. The Aroon Oscillator oscillates between -100 and 100 with zero as the centre crossover line - signals an upward trend when it rises above zero and a downward trend when it falls below zero.
The Aroon Oscillator was introduced by Tushar Chande in the September 1995 issue of Stocks & Commodities magazine. "Aroon" is a Sanskrit word meaning "dawn's early light".
