The Aroon Oscillator is calculated by subtracting the Aroon Down from the Aroon Up. The resultant number will oscillate between 100 and -100. The Aroon Oscillator will be high when the Aroon Up is high and the Aroon Down is low, indicating a strong upward trend. The Aroon Oscillator will be low when the Aroon Down is high and the Aroon Up is low, indicating a strong downward trend. When the Up and Down are approximately equal, the Aroon Oscillator will hover around zero, indicating a weak trend or consolidation. See the Aroon indicator for more information.
The Aroon indicator was developed by Tushar S. Chande and first described in the September 1995 issue of Technical Analysis of Stocks & Commodities magazine.
