Aroon Complete Guide
Aroon Indicator
What is Aroon?
The Aroon indicator, developed by Tushar Chande in 1995, is a technical tool used to identify trend changes and the strength of a current trend. Unlike many momentum oscillators that focus on price relative to price, Aroon focuses on time relative to price. It consists of two distinct lines: Aroon Up and Aroon Down. Aroon Up measures the number of periods since the highest high within a specified timeframe, while Aroon Down measures the periods since the lowest low. The default parameter is typically set to 25 periods. When Aroon Up is above 70 and Aroon Down is below 30, it indicates a strong bullish trend. Conversely, when Aroon Down is above 70 and Aroon Up is below 30, a strong bearish trend is present. A value near 100 suggests a new high or low was reached very recently, while a value near 0 suggests a significant amount of time has passed since a peak or trough. Crossovers between the two lines are often used as early signals for trend reversals. Traders also look for the lines to parallel each other, which suggests a consolidation phase. Practically, the indicator is most effective at identifying the transition from a sideways market to a trending one. To improve accuracy, it is often paired with other indicators like the ADX or moving averages to confirm trend sustainability.

FAQ
How does Aroon differ from the ADX indicator?
While both measure trend strength, Aroon focuses on the time between highs and lows, whereas ADX focuses on price expansion and moving averages of price ranges.
What does a value of 100 on the Aroon Up line mean?
A value of 100 means that the highest price in the look-back period (e.g., 25 days) occurred in the most recent period.
Can the Aroon indicator be used for short-term trading?
Yes, though the default is 25, short-term traders may reduce the period (e.g., to 10 or 14) to make the indicator more sensitive to quick price changes.
