### Aroon Oscillator

This study calculates and displays the Aroon Oscillator for the data specified by the Input Data High and Input Data Low Inputs. This indicator is closely related to the Aroon Indicators. See that study for an explanation of the notation used here.

We denote the Aroon Oscillator at Index $$t$$ as $$AO_t\left(X^{(High)},X^{(Low)},n\right)$$, and we compute it for $$t \geq 0$$ as follows.

$$AO_t\left(X^{(High)},X^{(Low)},n\right) = AI^{(Up)}_t\left(X^{(High)},n\right) - AI^{(Down)}_t\left(X^{(Low)},n\right)$$
