    Aroon Oscillator is a study that uses Aroon Indicator to quantify the strength of the current trend and the possibility of its further strengthening. The Aroon Oscillator is calculated as the difference between Aroon Up and Aroon Down. Fluctuating in a range from -100 to +100, high oscillator values indicate an uptrend while the low ones indicate a downtrend.

    Aroon Oscillator = Aroon Up - Aroon Down
    Aroon Up = 100 * (n-periods since n-day High) / n
    Aroon Down = 100 * (n-periods since n-day Low) / n

    n – the amount of periods
    n-day High – the n-days highest price
    n-day Low – the n-days lowest price
