Aroon Indicator.

The word aroon is Sanskrit for "dawn's early light." The Aroon
indicator attempts to show when a new trend is dawning. The indicator consists
of two lines (Up and Down) that measure how long it has been since the highest
high/lowest low has occurred within an n period range.

When the Aroon Up is staying between 70 and 100 then it indicates an upward trend.
When the Aroon Down is staying between 70 and 100 then it indicates an downward trend.
A strong upward trend is indicated when the Aroon Up is above 70 while the Aroon Down is below 30.
Likewise, a strong downward trend is indicated when the Aroon Down is above 70 while
the Aroon Up is below 30. Also look for crossovers. When the Aroon Down crosses above
the Aroon Up, it indicates a weakening of the upward trend (and vice versa).
