Aroon Indicator Explained: Best Settings & Strategy Tested

I test the Aroon Indicators Success Rates on 13,360 Years of Stock Data

In technical analysis, the Aroon indicator identifies trend reversals and trend strength. This oscillating indicator has two parts: the “Aroon Up” line measures uptrend strength, and the “Aroon Down” line for downtrend strength.

☆ Research You Can Trust ☆

My analysis, research and testing stems from 25 years of trading experience and my Financial Technician Certification with the International Federation of Technical Analysts.

I backtested the Aroon indicator across the DJ30 stocks over 360 years, plus a 26-year S&P 500 test, equaling over 13,360 years of testing data. Not all Aroon configurations work, but I discovered the most profitable settings.

Are you curious about profitable trading with Aroon? Join me for a deep dive into mastering this indicator! You’ll learn how to use Aroon effectively and strategically.

What is the Aroon Indicator?

The Aroon Indicator was developed by technical analyst Tushar Chande in 1995. This indicator measures a trend’s strength and helps identify possible trend reversals. It does this by drawing two lines, one which shows up-trends and the other which shows down-trends.

When looking at a chart, the Aroon lines will indicate if there is a strong uptrend or downtrend. It will also measure how long a trend has been in play and whether it’s weakening or continuing to be strong.

Key Highlights

  • Aroon is an oscillating indicator with two lines: Aroon Up and Down.
  • Aroon lines oscillate independently between 0 and 100.
  • Aroon does not provide an edge with standard settings on a daily chart.
  • Aroon has a 47% success rate based on multiple backtests using Aroon-25 on a 5-minute chart.
  • Selecting the right stock for Aroon can produce large gains.

How does the Aroon Indicator work?

The Aroon indicator works by plotting two lines on a chart, Aroon Up and Aroon Down:

• Aroon Up – This line measures the strength of an uptrend. It does this by looking at how many days since a new high was set and then plotting that value on the chart.

• Aroon Down – This line measures the strength of a downtrend. It does this by looking at how many days since a new low was set and then plotting that value on the chart.

The Aroon indicator is best used to identify potential trend reversals and determine when a trend is strong or weakening. When both lines are close together, it can indicate that a trend is weakening and may be about to reverse. A higher reading for either line indicates that the trend is strengthening.

The indicator can also help identify areas of support or resistance in advance, which can be used to place entry and exit signals. Lastly, the Aroon indicator can be used as a measure of momentum, allowing traders to identify potential breakouts or new trends. Knowing when to enter and exit a trade is key to successful trading, so using the Aroon indicator can help traders be more profitable.

Ultimately, our testing will reveal if the Aroon indicator is useful for identifying trend reversals and determining overall market strength.

How to Trade Aroon

When using the Aroon indicator, traders can look for buy and sell signals from a crossover in the lines. When the Aroon Up line crosses above the Aroon Down line, it is considered a bullish signal, indicating that an uptrend may be beginning. Similarly, when the Aroon Down line rises above the Aroon Up line, it is considered a bearish signal, indicating that a downtrend may be beginning. Traders can use either of these signals to indicate entering or exiting a position.

These signal lines will be the basis of our testing of the Aroon indicator. See the chart below for details on Aroon buy and sell signals.

But the big question is whether the Aroon buy and sell signals are profitable, like the ROC indicator, or if the Aroon is another chart indicator that does not work, such as moving averages.

Our original trading research is powered by TrendSpider. As a certified market analyst, I use its state-of-the-art AI automation to recognize and test chart patterns and indicators for reliability and profitability.

The Aroon Oscillator

Beyond just the crossovers in the lines, traders can also look for confirmation of buy and sell signals by analyzing the Aroon Oscillator. When the Aroon Oscillator rises above zero, it suggests that an uptrend is strengthening and can be used to confirm a buy signal. On the other hand, when the Aroon Oscillator drops below zero, this could be interpreted as a weakening downtrend, confirming a sell signal. Additionally, traders should consider the magnitude of the Aroon Oscillator when interpreting buy and sell signals. The bigger the distance away from zero, the stronger the trend.


The Aroon indicator is a reliable measure of trend strength and can be used to determine the direction of price movements. It can also provide helpful insight into potential reversals in market trends. The indicator is easy to use and provides traders with an effective way to identify signals for when to enter or exit positions.


The main drawback to using the Aroon indicator is its performance track record. Although the indicator is reliable in measuring trend strength, it can be prone to false signals, which could lead to losses. Additionally, the Aroon indicator only measures peaks and troughs in price action over a specific time frame and may miss out on potential opportunities if not used correctly. Finally, the Aroon indicator does not consider other factors, such as volume or support/resistance levels, which can provide additional information for trading decisions.

Overall, the Aroon indicator can be a helpful tool for traders looking to identify trend direction and strength in price action. However, it should not be used solely on its own, and traders must combine the Aroon indicator with other analysis methods to make sound trading decisions.

How to Calculate the Aroon Indicator

Aroon is automatically calculated using the best charting software, such as TrendSpider or TradingView. But if you want to calculate Aroon yourself, read on.

To calculate the Aroon Indicator, traders must first find the maximum high over a given period (usually 25 days). The highest closing price in that period is divided by the total number of trading days. This calculation is repeated for the lowest low over the same period, and that value is divided by the total number of trading days. The result for the maximum high and lowest low is then subtracted from each other to form the Aroon Oscillator.

The Aroon indicator is calculated by subtracting the number of days since the most recent 25-day period high from the number of days since the most recent 25-day period low.

The Aroon Indicator Formula

Aroon is mathematically expressed as:

Aroon Up = (25 – Days Since 25-day High) / 25

Aroon Down = (25 – Days Since 25-day Low) / 25. 

The resulting values are then used to generate a line graph representing the trend strength over a given period. The farther away each line lies from zero, the stronger the trend. If the lines are crossing, this indicates a weakening or reversal of the trend. Aroon Oscillator is calculated by subtracting Aroon Down from Aroon Up and expressed as AO = Aroon Up.

Aroon Buy & Sell Signal Interpretation

When the Aroon Oscillator is above zero, this could be interpreted as a strengthening uptrend, confirming a buy signal. On the other hand, wh

The two lines of the Aroon indicator (up & down) are calculated separately and can offer valuable insight into a stock’s trend. For example, if both lines are rising, this suggests an increase in momentum and that the stock is entering a strong directional trend. The higher the value of the Aroon indicator, the stronger the trend is. If both lines are declining, this may indicate a weakening uptrend and confirm a sell signal. Additionally, if one line rises while the other falls, it could indicate that there is not enough momentum to continue in its current direction and could indicate a potential reversal.

Aroon Indicator Backtesting Results

I tested the standard configuration of Aroon 25 on the Dow Jones Industrial Average stocks on four timeframes: 1-minute, 5-minute, 1-hour, and daily charts, and the results were surprising. On a 1-minute chart, Aroon produced only a 27% success rate, and a 5-minute chart over two months produced a 47% win rate.

Interestingly, the standard setting of Aroon 25 on a daily chart, widely recommended by supposed experts, produced an incredibly poor 3% win rate.

Aroon Indicator Test OHLC Chart Duration % Winners Avg # Trades
Setting 25 1-min 20 Days 27% 92
Setting 25 Best 5-min  2 Months 47% 89
Setting 25 1-hour 2 Years 20% 75
Setting 25 Daily 12 Years 3% 55
Average 24% 85

The Best Aroon Indicator Settings

Our 360 years of TrendSpider backtests revealed conclusively that the best setting for Aroon is using Aroon-25 on a 5-minute chart. This produced a win rate of 47% versus a buy-and-hold strategy. That might not seem like more than a 50-50 chance of success. However, some of the profitable stocks were incredibly successful.

Next, I will show a selection of those successful trades.

Combining Aroon with Other Indicators

The Aroon indicator can be combined with other technical indicators to form a complete trading strategy. For example, using the MACD or Moving Average Convergence Divergence indicator, you can set up a strategy that buys when the Aroon 25 Up reaches positive values. At the same time, the MACD crosses above its signal line. Additionally, you can use the MACD’s Histogram to signal when a trade should be exited. Alternatively, you can try to combine Aroon with the Price Rate of Change or bullish chart patterns.

To test whether combining Aroon with other indicators is profitable, I suggest using TrendSpider, our recommended stock research, and AI-powered trading software.

Can the Aroon be used for Buy and Sell Signals?

Yes, our 13,360 years of data across the DJIA and S&P500 suggests the standard Aroon setting of 25 on a 5-minute chart is useful for identifying profitable buy and sell signals with a 47% success rate and 54% average winning trades. Beware, some of the losing trade will be larger, which weighs on the overall indicator performance.

Should You Use the Aroon Indicator?

Yes, our testing shows using Aroon on its standard setting of 25 on a 5-minute chart is a profitable tool for trading, but you will need to combine it with a solid stop-loss strategy to reduce the size of losing trades. On a daily chart, it failed to beat the S&P 500 over 26 years.
