Parameters

seriesName
The name of the series which will be displayed on the chart, i.e. its label.
s

Return Value

Returnsa series where the first term is the values of the Aroon Up indicator over the earliest set of consecutive periods and the second term is the value of the next set of the periods (i.e. the windows is moving one place along), and so on.

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).
