Key takeaways. Average directional index (ADX) is a short-term chart indicator. It can be used to help you evaluate the market or an investment's strength. ADX currently suggests the short-term momentum behind stocks may be strong, with a caveat.
The ADX provides the dominant decision-making criteria—allowing you to see whether there is a trend or not and how strong it may be. The RSI provides the secondary evidence—real-time analysis of whether that investment is in overbought or oversold territory.
