Introduction to ADX (Average Directional Index)
The Average Directional Index (ADX) is a powerful technical indicator used by traders to measure the strength of a trend. Developed by J. Welles Wilder, ADX helps in determining whether a stock or an index is trending or moving sideways. It is widely used in combination with other indicators for a comprehensive trading strategy.
Average directional index (ADX)
What is ADX (Average Directional Index)?
ADX is a trend strength indicator that consists of three main components:
- ADX Line - Measures the strength of the trend.
- +DI (Positive Directional Indicator) - Shows the strength of the uptrend.
- -DI (Negative Directional Indicator) - Shows the strength of the downtrend.
The ADX value ranges from 0 to 100, where:
- Below 20 indicates a weak or non-trending market.
- Between 20 and 40 suggests a developing trend.
- Above 40 signifies a strong trend.
How to Calculate ADX?
The calculation of ADX involves multiple steps:
- Calculate +DI and -DI: +DI = (Current High - Previous High) -DI = (Previous Low - Current Low)
- Calculate the True Range (TR): TR = Maximum of (Current High - Current Low, Absolute(Current High - Previous Close), Absolute(Current Low - Previous Close))
- Calculate the Directional Movement Index (DX): DX = (|+DI - -DI| / |+DI + -DI|) * 100
- Find the ADX: ADX = 14-period average of DX values
Strategies Using ADX
1. ADX Crossover Strategy
- Bullish Signal: When +DI crosses above -DI, it suggests an uptrend.
- Bearish Signal: When -DI crosses above +DI, it suggests a downtrend.

2. ADX with Moving Averages
- Combining ADX with moving averages like 50 EMA or 200 EMA can help confirm trend strength.
- If ADX > 25 and price is above the 50 EMA, it confirms an uptrend.

3. ADX with RSI
- If RSI > 70 and ADX > 40, it signals an overbought but strong uptrend.
- If RSI < 30 and ADX > 40, it signals an oversold but strong downtrend.
