The Aroon Oscillator is a derivative of the Aroon indicator that provides a different way to view the results. It is constructed by subtracting Aroon Down from Aroon Up. The Aroon Oscillator oscillates between -100 and +100 with zero as the center line.
The Aroon Oscillator provides the following signals:
- Above zero signals an uptrend.
- Below zero indicates a downtrend.

Formula
[Aroon;Osc = Aroon;Up – Aroon;Down]
The formula uses the following equations, where n is the number of days:
[ Aroon;Up = frac{100 * (n – (Days;Since;n-day;High))}{n} ]
[ Aroon;Down = frac{100 * (n – (Days;Since;n-day;Low))}{n} ]
Aroon Down = 100 x (n – Days Since n-day Low)/n
