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