  • The ADX, developed by Welles Wilder, measures the strength of a prevailing trend, and determines whether there is a movement or direction in the market.
  • A simple and effective strategy that is used by many traders is a crossover strategy that uses the ADX in combination with the +DMI and –DMI lines.
  • Firstly, the ADX is used to determine if a market is even trending rather than simply fluctuating within a range.
  • It doesn’t incorporate all of the data necessary for a thorough price action analysis, so it’s advised to use it in combination with other indicators.
  • In the chart in figure 1, when the ADX crossed above 20, it was an indication the upward trend in the stock price might be strengthening.

In this example, both the DMI crossovers took place a little earlier than the trend strengthening or weakening signals from the ADX. But the +DI was above the -DI when the ADX was trending higher, and the -DI was below the +DI when the ADX was below 20. Even though DMI and ADX together can potentially identify trend reversals and indicate the strength of trending stocks, there may be times when the signals may not be valid.

Aroon-up reflects the number of days since the last 25-day high, while Aroon-Down represents the number of days since the 25-day low. While the ADX can indicate the current trend, a reversal in the trendline shouldn’t necessarily be the next move. Prices may instead enter a consolidation phase and drift sideways for a while.
