Parameters

s

lengthOfPeriod
An integer which represents the length of the period over which the indicator will be iteratively evaluated.

Remarks

Evaluation of the Aroon Oscillator

The Aroon Oscillator over each period is evaluated using the following formulae:

Aroon Oscillator = (Aroon Up Indicator) - (Aroon Down Indicator)

where 'Aroon Up Indicator' and `Aroon Down Indicator' are evaluated using.

The Aroon Up indicator is given by:

100(n - (number of days since last highest high over n days))/n

where n is the number of days being considered (a reasonable default value for n is 14).

The Aroon Down indicator is given by:

100(n - (number of days since last highest high over n days))/n

where n is the number of days being considered (a reasonable default value for n is 14).
