To determine the direction of the trend, you can look at the actual price action. The best RSI ADX trading strategy can help you trade better and achieve your goals faster. Detecting a strong directional move is a vital skill for any trader. Another common mistake is when traders consider a falling ADX line a sign of a trend reversal. If the line is just falling but still above the 25-mark, it indicates that the trend is weakening.

Next up, you’ll have to calculate the Negative Directional Movement Line . Do this by subtracting the current low from the previous low to get the Negative Directional Movement. The first step is to calculate the Positive Directional Movement Line .

Also, the Ichimoku indicator will be used to determine the current market trend. The advantage of the Ichimoku is the fact that offers a unique perspective of support and resistance, representing these levels based on price action. The most common mistakes traders make are around using the ADX to signal bullish or bearish trends. The tool is designed to measure trend strength but cannot determine what direction the trend goes in.

When any indicator is used, it should add something that price alone cannot easily tell us. For example, the best trends rise out of periods of price range consolidation. Breakouts from a range occur when there is a disagreement between the buyers and sellers on price, which tips the balance of supply and demand. Whether it is more supply than demand, or more demand than supply, it is the difference that creates price momentum.

SharpCharts users can plot these three directional movement indicators by selecting Average Directional Index from the indicator dropdown list. By default, the ADX line will be in black, the Plus Directional Indicator (+DI) in green and the Minus Directional Indicator (-DI) in red. This makes it easy to identify directional indicator crosses.

Average Directional Movement Index Reading

Setting an ADX requirement will reduce signals, but this uber-smoothed indicator tends to filter as many good signals as bad. In other words, chartists might consider moving ADX to the back burner and focusing on the Directional Movement Indicators (+DI and -DI) to generate signals. These crossover signals will be similar to those generated using momentum oscillators. Therefore, chartists need to look elsewhere for confirmation help.

Conversely, if the -DI line is above the +DI line, it suggests a bearish trend. The strength of that trend is reflected in the ADX line. For traders, the good news is that modern trading software performs these calculations for you automatically. The standard MetaTrader 4 platform comes with the ADX indicator included, so there’s no need for a separate ADX indicator download.


In order to profit from the market, it’s necessary to have a disciplined approach to trading. It is also important to keep things simple and don’t over-complicate your trading. Several candles later, the market offered the chance to add long positions, or to re-enter with new positions, as the +DI closed again above 20 level. The default value is 14, and the standard way of depicting the ADX is to show three lines below the main price chart.

A series of lower peaks, on the other hand, in a decreasing trend. That’s not all – you should keep an eye on where both lines are compared to each other. If the +DI floats above the –DI, the market is usually in an uptrend. Traders use the lines and the relation between them to decide whether they should go long, short or avoid trading altogether. The ADX is an indicator that allows you to understand the strength of a trend.

These two indicators are often collectively referred to as the Directional Movement Indicator . The average directional index helps traders see the trend direction as well as the strength of that trend. ADX is non-directional and quantifies trend strength by rising in both uptrends and downtrends. ADX is plotted as a single line with values ranging from a low of zero to a high of 100.

A Brief History of the ADX

However, like any other indicator, the ADX isn’t perfect, and it doesn’t fit all market conditions. That is why it is essential to get familiar with its drawdowns and benefits before deciding whether it can help improve the efficiency of your trading strategy. Lastly, make sure to avoid trading during ranging markets as the ADX is prone to generating false positives if not accompanied by a leading indicator.


We are going to backtest our strategy by investing a hundred thousand USD into our trading strategy. So first, we are storing the amount of investment into the ‘investment_value’ variable. After that, we are calculating the number of Apple stocks we can buy using the investment amount. The number of stocks should be an integer but not a decimal number. Using the ‘floor’ function, we can cut out the decimals. Remember that the ‘floor’ function is way more complex than the ‘round’ function.

Reading the ADX Indicator

5 things to keep an eye on in the seo world is the most effective when the market is trending, which, fortunately, is most of the time. When there is a well-established trend, make sure to look for crossovers between the +DI and the –DI lines. When ranging, the trend is moving sideways, and the market is kind of calm, without the significant prevalence of either buyers or sellers. Should the supply/demand ratio change, however, the market will react by breaking the range. The ADX line is usually plotted in white, while the +DI and DI lines are green and red.

When + DI and -DI begin to converge again, this indicates the trend is gradually fading. 50-100% is the area where ADX peaks and the trend is ending. At this time, start looking for opportunities to exit the market. There might be a range consolidation or a small local rollback, after which the main movement will continue. High and Low are the maximum and minimum values, while i and i-1 are the current and previous low and high periods, meaning the current and prior bars or candles.

  • The second pairing shows an outside day with Minus Directional Movement (-DM) getting the edge.
  • An ADX reading above 25 signals that a strong trend is in place.
  • It will cover sentiment analysis, how to benefit from market sentiment, the different types of sentiment indicators available in the market, and more!
  • The first technique is used to smooth each period’s +DM1, -DM1 and TR1 values over 14 periods.
  • Once the trend develops and becomes profitable, traders will have to incorporate a stop-loss and trailing stop should the trend continue.

Notice that there was no sell signal between the March and July buy signals. This is because ADX was not above 20 when -DI crossed above +DI in late April. It’s important to understand the effects of all the smoothing involved in the ADX, +DI and -DI calculations. Because of Wilder’s smoothing techniques, it can take around 150 periods of data to get true ADX values. Wilder uses similar smoothing techniques with his RSI and Average True Range calculations.

When the +DI line crosses above the –DI one and the ADX ranges above 25, this is considered a buy signal. On the other hand, when the –DI crosses above the +DI and the ADX ranges above 25, traders usually go short. Bear in mind that the ADX is a trend strength indicator made up of PDI and NDI, representing a positive and negative trend direction respectively. Technical analysis focuses on market action — specifically, volume and price. Technical analysis is only one approach to analyzing stocks.

How to Read the Average Directional Index Indicator

Then, we look the pivot points around the price action, to establish potential entry points. Bars making lower highs and lower lows compared to the previous bar are allocated a negative DM. Bars making higher highs and higher lows compared to the previous bar are allocated a positive DM.

Keep in mind that when +DI crosses above the -DI, you can begin place positions and place a short position when -DI crosses above +DI. The ADX Indicator actually works best when combined with other technical indicators. One of the best combinations is with the Relative Strength Index, or RSI.

Similarly, a signal to sell will be triggered when the MACD falls below the zero line, with the ADX rising above 20 and the -DI line crossing above the +DI line. A wrong combination can also lead to laying more emphasis on a single price element while overlooking other crucial cues. In the above case, a trader could land up focusing on trend momentum while overlooking other important elements such as volatility. If the Keltner Channel’s is positive, pointing upward, we start looking for buy signals only. If the Keltner Channel’s is negative, pointing downward, we start looking for sell signals only. Keltner Channel is practically a hybrid between an exponential moving average and the Average True Range indicator.
