The ADX is a technical analysis indicator that measures the strength of a trend, whether it's up or down. It's a non-directional indicator, which means that it doesn't indicate the direction of the trend, only the strength of the trend. The ADX can be used in a variety of trading strategies, including identifying trending markets, determining trend direction, and even as a filter for other indicators. In this article, we'll explore the ADX in detail and show you how to use it to improve your trading.
