Aroon

In the fast-paced world of the Indian share market, identifying market trends and spotting reversals early is crucial for traders and investors. One of the technical tools that has proven highly effective in achieving this is the Aroon Indicator. Developed by Tushar Chande in 1995, the Aroon Indicator is designed to identify the strength of trends and the likelihood of reversals, making it a favorite among traders seeking to maximize their gains.

This 2000-word blog will explore how the Aroon Indicator works, its advantages, limitations, and its historical performance in the Indian stock market. We’ll also look at how you can incorporate this powerful tool into your trading strategy.

What is the Aroon Indicator?

The Aroon Indicator is a technical tool that identifies trends and potential reversals by measuring the time between highs and lows over a set period. Unlike moving averages that smooth out price data, the Aroon Indicator focuses on how recently the highest high and lowest low occurred. This makes it particularly effective in detecting the start of new trends or confirming existing ones.

The Aroon Indicator consists of two lines:

• Aroon Up: Measures how long it has been since the highest price occurred within a specified period.
• Aroon Down: Measures how long it has been since the lowest price occurred within the same period.

Both lines move between 0 and 100. A value near 100 for the Aroon Up suggests a strong uptrend, while a value near 100 for the Aroon Down indicates a strong downtrend.

Formula and Calculation

The Aroon Indicator is calculated as follows:

Aroon Up=((Days Since Last High−Period)​/Period)×100

Aroon Down=((Days Since Last Low−Period)/Period​)×100

For example, if you are using a 14-day period and the highest price occurred 5 days ago, the Aroon Up would be calculated as:

Aroon Up=((14−5​)/14)×100=64.28

This value indicates that the market has experienced an upward trend recently.

The Aroon Indicator has proven its value in identifying trends and reversals in the Indian stock market, particularly in major indices like the Nifty 50 and Sensex. Historical data shows how traders have successfully used this tool to enter and exit trades at the right time.

How to Use the Aroon Indicator in the Indian Share Market

The Aroon Indicator is an excellent tool for both short-term and long-term traders. It helps identify the beginning of new trends and confirms ongoing trends, allowing traders to make informed decisions.

Step-by-Step Guide to Using the Aroon Indicator

1. Identify Trends: If the Aroon Up is above 70 and the Aroon Down is below 30, it indicates a strong uptrend. Conversely, if the Aroon Down is above 70 and the Aroon Up is below 30, it signals a downtrend.
2. Spot Trend Reversals: The Aroon Indicator is also effective in spotting reversals. If the Aroon Up crosses below the Aroon Down, it could indicate that a bullish trend is weakening, and a bearish reversal is on the horizon.
3. Confirm with Other Indicators: While the Aroon Indicator is effective in identifying trends, it works best when used with other technical indicators like the Moving Average Convergence Divergence (MACD) or the Relative Strength Index (RSI) to confirm signals.
4. Use the Aroon Oscillator: The Aroon Oscillator, which is the difference between Aroon Up and Aroon Down, can also be used to confirm trends. A positive value indicates a bullish trend, while a negative value points to a bearish trend.

Example: Applying the Aroon Indicator to Nifty 50 in 2021

1. Identifies Trend Strength: The Aroon Indicator provides a clear picture of whether a market is in a strong trend or a consolidation phase. This allows traders to focus on trending markets and avoid range-bound ones.

Limitations of the Aroon Indicator

Despite its many advantages, the Aroon Indicator has some limitations:

• False Signals in Choppy Markets: In sideways or range-bound markets, the Aroon Indicator may provide false signals. This is why it’s important to confirm Aroon signals with other technical indicators.
• Lagging Nature: Like most trend-following indicators, the Aroon Indicator can lag behind the market. This means that traders might enter or exit trades after a significant portion of the trend has already occurred.
• Limited Use for Short-Term Traders: The Aroon Indicator is more effective for longer-term trends and may not be ideal for intraday or very short-term traders.

Comparison with Other Trend Indicators

To better understand the strengths and weaknesses of the Aroon Indicator, let’s compare it with other popular trend indicators such as the Moving Average and MACD.
