What is the ADX indicator?

The ADX indicator, which stands for Average Directional Index, is widely used in financial markets as a tool for technical analysis. Its primary purpose is to assess the strength and direction of a trend in order to assist traders in determining whether an asset is experiencing a clear trend or is moving within a range.  By utilizing the ADX indicator, traders gain valuable insights into the market's behaviour. It consists of three lines: ADX, +DI, and -DI. The ADX line represents the overall strength of the observed trend, while the +DI line measures the strength of the upward movement, and the -DI line gauges the strength of the downward movement. The ADX indicator is a valuable tool for traders in assessing the strength and direction of a trend and thereby aiding in making informed trading decisions. When used in conjunction with other technical analysis tools, the ADX indicator can enhance trading strategies and improve overall trading outcomes.

How to calculate the ADX indicator?

To calculate the ADX indicator, you need to perform several calculations. Here are the steps involved:

• Calculate the Positive Directional Indicator (+DI):
  • +DI = (Smoothed Moving Average of + DM / Average True Range) * 100
• Calculate the Negative Directional Indicator (-DI):
  • -DI = (Smoothed Moving Average of - DM / Average True Range) * 100
• Calculate the Directional Movement Index (DX):
  • DX = ([+DI (-) -DI] / [+DI (+) -DI] * 100
• Initial ADX calculation = the sum of the ‘n’ period of DX / n
• Subsequent ADX calculation = [{previous ADX * (n-1)} + current DX] /n

In these formulas:

• +DM represents the current high minus the previous high.
• -DM represents the previous low minus the current low.
• ATR (Average True Range) is a measure of price volatility.
• ‘n’ refers to the number of periods considered for the calculations. The default period is 14, but you can adjust it based on your preference or analysis time frame.

By following these steps and formulas, you can calculate the ADX indicator, which provides insights into the strength and direction of a trend in the market.

How to trade using the ADX indicator?

The ADX indicator ranges between 0-100 and the interpretation of the value of the ADX indicator is explained below.

• ADX values below 25

When the ADX value is below 25, it suggests a weak or absent trend. The market may be ranging or experiencing choppy price movements rather than following a clear trend. Traders should exercise caution and consider alternative strategies suitable for range-bound conditions.

• ADX values between 25 and 50

ADX values within this range indicate a moderate to strong trend. A rising ADX line suggests increasing trend strength. Traders may consider entering trades in the direction of the trend, using appropriate entry and exit signals aligned with their trading strategy.

• ADX values above 50

ADX values above 50 indicate a very strong trend. This suggests a high level of trend strength and reliability. Traders may look for opportunities to ride the trend and consider holding positions for longer durations, using trailing stops to protect profits.

• +DI and -DI crossovers

Pay attention to the +DI and -DI lines. When the +DI line crosses above the -DI line, it suggests a bullish trend, indicating potential buying opportunities. Conversely, when the -DI line crosses above the +DI line, it signals a bearish trend, indicating potential selling opportunities.

• Directional Movement Index (DX) values

The DX value, derived from the difference between +DI and -DI, provides insights into the momentum of the trend. Higher DX values indicate stronger momentum and a more pronounced trend.

• Divergence between price and ADX

Monitor for any divergences between the price action and the ADX indicator. If the price is making higher highs or lower lows, but the ADX is not confirming the trend strength, it could suggest a potential weakening of the trend or an upcoming reversal. The ADX indicator is not a directional indicator itself but rather measures the strength and presence of a trend. It is often used in combination with other technical analysis tools and indicators to make informed trading decisions.
