The Aroon Oscillator is a trend-following indicator used in technical analysis to gauge the strength of a current trend and the likelihood that it will continue. It was developed by Tushar Chande in 1995 and is part of the Aroon Indicator family. The Aroon Oscillator provides insights into the prevailing market trend, helping traders make more informed decisions.
Calculation Formula
The Aroon Oscillator is derived from two components of the Aroon Indicator: the Aroon Up and the Aroon Down. It is calculated as follows:
Aroon Up Formula
Aroon Down Formula
Where:
- \( N \) is the number of periods (commonly set to 25).
Trade Signals
The Aroon Oscillator oscillates between +100 and -100. The signals generated by the oscillator help traders identify potential entry and exit points.
Bullish Signals
- Above Zero: When the oscillator is above zero, it suggests a bullish trend.
- Rising Oscillator: An increasing Aroon Oscillator value indicates strengthening bullish momentum.
Bearish Signals
- Below Zero: When the oscillator is below zero, it signifies a bearish trend.
- Declining Oscillator: A decreasing Aroon Oscillator value points to strengthening bearish momentum.
Special Considerations
- Zero Line Crossovers: Crossovers of the zero line are significant as they indicate a potential change in trend direction.
- Extreme Values: Values near +100 or -100 denote strong trends, whereas values near zero suggest a lack of trend or sideways movement.
Examples
Example 1: Bullish Signal
When the Aroon Up reaches 80 and the Aroon Down falls below 20, and the Aroon Oscillator crosses above zero, it indicates a strong bullish trend.
Example 2: Bearish Signal
When the Aroon Down reaches 80 and the Aroon Up falls below 20, and the Aroon Oscillator crosses below zero, it signifies a strong bearish trend.
Historical Context
The Aroon Indicator, including the Aroon Oscillator, was developed by Tushar Chande in 1995 to enhance trend detection efficiency compared to other indicators like the Moving Average Convergence Divergence (MACD).
Applicability
The Aroon Oscillator is applicable across various asset classes, including stocks, commodities, and forex. Its versatility makes it a valuable tool for both short-term and long-term traders.
Comparisons with Related Indicators
- Moving Average Convergence Divergence (MACD): Both serve to identify trends, but the MACD uses moving averages, while the Aroon Oscillator is based on the highs and lows over a specified period.
- Relative Strength Index (RSI): Unlike the RSI, which measures momentum, the Aroon Oscillator focuses on trend strength and direction.
Related Terms
- Trend Indicator: A type of technical indicator used to identify the direction of market movements over a certain period.
- Technical Analysis: The study of past market data, primarily price and volume, to forecast future price movements.
