Parameters

s: An financial series of the trading highs over the last n-periods where the k-th term of the array if the trading high on the k-th previous period.
lengthOfPeriod: An integer which represents the length of the period over which the indicator will be iteratively evaluated.

Return Type

Remarks

This indicator for each period will return a value between 0 and 100, where a higher value indicates that the highest high was achieved more recently. Persistent values between 70 and 100 are said to indicate strength in the asset and in conjunction with a low range(i.e. 0-30) of the Aroon Down indicator, indicates an upward trend.

Evaluation of the Aroon Up Indicator

The Aroon Up indicator for each period 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).
