Aroon Indicator
The Aroon oscillator is a technical indicator used to measure whether a security is in a trend, and more specifically if the price is hitting new highs or lows over the calculation period ,typically 25
The indicator can also be used to identify when a new trend is set to begin. The Aroon indicator comprises two lines: an Aroon-up line and an Aroon-down line
When the Aroon-up crosses above the Aroon-down, that is the first sign of a possible trend change. If the Aroon-up hits 100 and stays relatively close to that level while the Aroon-down stays near zero, that is positive confirmation of an uptrend
The reverse is also true. If Aroon-down crosses above Aroon-up and staysnear 100, this indicates that the downtrend is in force
