ADX Parameters Forex is a set of technical indicators used in the field of Foreign Exchange trading. These indicators help traders assess the strength of a trend, identify buying and selling opportunities, and make better, informed decisions regarding their own investments. Key ADX parameters include Average Directional Index (ADX), +DI and -DI, and Parabolic SAR. ADXs are calculated by determining the price range of a particular currency over a period of time, while DI’s and the Parabolic SAR offer additional predictive power to help traders see support and resistance lines. Using these parameters, investors can accurately gauge the momentum and strength of a trend, identify potential issues and opportunities, and adjust their risk management accordingly.
