Adx Average Directional Index

directional indicator

There are many trading indicators that promise to help you find profitable trading opportunities. When the ADX is above 25, according to Wilder, there is a strong trend, and when it is below 20, there is no trend. ADX Crossing 10 from Below indicates that the stock is entering the range bound zone whereas ADX Crossing 10 from Above indicates that the trend is weak.


Alongwith ADX, +DI and -DI form a powerful tool for the traders. These three indicators can be separated into separate charts to reduce clutter. Some traders may only choose to view the ADX for trend strength, while others may prefer +DI and -DI to confirm price trend.

ADX Charting

The second option turned out to be more effective, since I wasn’t completely guided by the data but also levels and Price Action. ADX assists you, but it can’t be considered the main indicator. Open a deal or increase the trade volume following the trend. Open a trade on the next candle after all the conditions are met. Close the trade based on ADX — when all three lines turn downward. All three indicators are intertwined and move horizontally.

  • In this section of the guide, we’ll cover some of the most popular and common ADX trading strategies.
  • If the red line(-DI) is higher than the green line(+DI) that is generally an indication of a bearish trend.
  • The indicator was developed by Welles Wilder, who created several core trading indicators.
  • Neither our company, nor its directors, employees, trainers, or coaches shall be in any way liable for any claim for any losses or against any loss of opportunity for gain.
  • A rising ADX line generally means that an existing trend is strengthening.

If you can’t identify the most likely market development, it might even be a good idea to capture your profits and close your positions. At first, the indicator was intended to serve the needs of commodity day traders. However, today, it is applied across almost all markets, including stocks, ETFs, mutual funds, and futures. This step is optional but it is highly recommended as we can get an idea of how well our trading strategy performs against a benchmark .

ADX Indicator: All About the Calculation

Let’s now dive into the main concept of this article, the Average Directional Index. The Parabolic SAR, or Parabolic Stop and Reverse, is a trailing stop-based trading system and is often used as a technical indicator as well. Welles Wilder for analysing commodity price charts but can be perfectly applied to any markets and timeframes.

If the +DI line is above -DI after crossing and continues to move upward, it signifies a beginning of an uptrend. In the first scenario, the downtrend movement ended as soon as the index reached the 50th level. In the second scenario, the downtrend continued but gradually transitioned into a sideways movement.

To confirm the signal, you need to analyze where all three lines of the index are positioned relative to each other and to the 0-100% range conditions. DM can be of either the M value calculated during the previous step or 0, depending on whether the algorithm condition is met. +M is an absolute positive price movement, -M is an absolute negative price movement. The chart below shows the average directional index indicating an increasingly strong uptrend as average directional index readings rise from below 10 to nearly 50. The ADX is a lagging indicator, meaning a trend must have established itself for the indicator to generate a signal that a trend is underway. ADX values range between 0 and 100, in which high numbers signify a strong trend and low numbers suggest a weak trend.

The divergence signals generated by the ADX are very similar to those from oscillators like the MACD or the RSI. When the instrument’s price makes a higher high, while the ADX makes a lower high, you have a divergence. This isn’t necessarily a reversal signal but mostly a warning that the trend is changing. Also, make sure to look at whether the ADX line marks consecutive higher highs or lower highs. In the first case, it means the trend momentum is increasing. A series of lower peaks, on the other hand, indicate a decreasing trend.

Chapter 3: Trading with the ADX

A buy order in a ranging market will be when the price is drifting lower, with an ADX reading of below 25, and when the RSI is showing oversold conditions. Similarly, a sell order can be placed when the price is edging higher, with an ADX reading of below 25 and when the RSI is showing overbought conditions. The Alligator is a versatile basic indicator with a simple yet effective calculation formula. Trade theory suggests adding trend tools to the oscillator – for example, a moving average or a combination of ADX and EMA.

Trading and investing in financial markets involves risk. The first technique is used to smooth each period’s +DM1, -DM1 and TR1 values over 14 periods. As with an exponential moving average, the calculation has to start somewhere so the first value is simply the sum of the first 14 periods. As shown below, smoothing starts with the second 14-period calculation and continues throughout. After all these steps, it is time to calculate the Average Directional Index line.

ADX may be applied to any trading instrument, including stocks, indices, commodities and Forex. The ADX doesn’t really consider trend direction but rather the strength of the trend. The ADX is often used along with the directional movement index , which is made up of the plus directional indicator (+DI) and the minus directional indicator (-DI). These two indicators, +DI and -DI, measure a trend’s direction by looking at the difference between current and previous highs and lows.

overbought and oversold

Now, let’s compare our returns with SPY ETF (an ETF designed to track the S&P 500 stock market index) returns. Before moving on, it is essential to know what backtesting is. Backtesting is the process of seeing how well our trading strategy has performed on the given stock data. In our case, we are going to implement a backtesting process for our Average Directional Index trading strategy over the Apple stock data.

The ability to quantify trend strength is a major edge for traders. ADX also identifies range conditions, so a trader won’t get stuck trying to trend trade in sideways price action. In addition, it shows when price has broken out of a range with sufficient strength to use trend-trading strategies. ADX also alerts the trader to changes in trend momentum, so risk management can be addressed. If you want the trend to be your friend, you’d better not let ADX become a stranger. The chart above shows Medco Health Solutions with the three directional movement indicators. absolute positive (+M) and negative (-M) price movements – the difference between the price highs and lows of the current and previous low and high calculation period. Start looking for an opportunity to exit the trade on the forex market when the dotted lines are at the maximum distance and begin to converge. In the area highlighted by the red rectangle, the index line reverses inside the range in addition to the dotted lines’ reversal – it means the forex trading activity is weakening. This is also confirmed by the candlestick analysis while trading forex- red candlesticks have shorter bodies with each subsequent candlestick. Close your position while trading forex when you see the first green candle. Opening a trade during the reverse crossover of +DI and -DI, ADX rose over the 40th level.

This can be used instead of waiting for the +DI and -DI crossovers. As you can see from the screenshot, a flat occurs at the divergence of moving averages. As soon as the Alligator lines begin to diverge, we check the oscillator signals and open a trade on the candle indicated by the red arrow. Close the trade on the candlestick marked with a yellow arrow, as all three lines of the oscillator turned downward.

When +DI and -DI crosses, it indicates that a trend reversal is occurring. The trend is turning bullish if +DI is crossing above -DI; similarly, the trend is turning bearish if -DI is crossing above +DI. It will be a case of a particularly strong trend if a cross occurs when the ADX line is also going up.

It implies that the array is sorted by descending where the latest data point is on the left side of the array. Time-series is utilized to store historical data and comprise the time information.

Wilder created the indicator for trading commodities futures as a commodity trader. Technical analysts have since broadly adapted it to nearly every other tradeable investment, including stocks, currency, and ETFs.

After all, the may be your friend, but it sure helps to know who your friends are. In this article, we’ll examine the value of ADX as a trend strength indicator. The Directional Movement System indicator calculations are complex, interpretation is straightforward, and successful implementation takes practice.
