Aroon

Gauges trend strength by the time elapsed since the last high and low. Aroon consists of two lines: Aroon Up (time since the last high within the period) and Aroon Down (time since the last low within the period). Values range from 0 to 100. Aroon Up above 70 and Aroon Down below 30 signal an uptrend. A crossover of the lines — a trend change.

Formula:

Aroon Up = 100 * (period - bars_since_high) / period
Aroon Down = 100 * (period - bars_since_low) / period
