The Wilder's Directional Movement Index (DMI) Indicator, also known as Average Directional Index (ADX), is a technical analysis indicator used to determine the strength of a trend in a financial market, such as stocks, currencies, or commodities. It was developed by Welles Wilder and is used to determine whether a market is trending or not, and if so, the direction and strength of the trend.The ADX indicator calculates two values: the Positive Directional Index (PDI) and the Negative Directional Index (NDI), which are then used to determine the ADX value. The ADX value ranges from 0 to 100 and a reading above 25 is considered a strong trend, while a reading below 20 is considered a weak trend or sideways movement. The indicator is often used in conjunction with other technical indicators to form a complete trading strategy.It's important to note that while the ADX indicator can be a useful tool for determining the strength and direction of a trend, it should not be relied upon solely in making trading decisions, as other factors such as market volatility, economic data releases, and geopolitical events can also impact market prices.
