ADX

The ADX indicator supplied with NinjaTrader cannot be used with an input series other than price. We have recoded it so that you may apply it to other indicators. To do so, simply select any of the other NinjaTrader indicators as input series.

Indicator Description

The Average Directional Index  (ADX) was developed by J. Welles Wilder and tells us the strength of a trend. The calculation is based on a moving average of the price range expansion over a specific time period.

Specifically, the indicator plots as a single line with values ranging from 0 to 100. The indicator is non-directional, and simply registers the trend strength, irrespective of whether price is trending up or down.

Our version of the Average Directional Index allows for setting the DM and ADX periods independently. It is therefore possible to adapt the ADX to Dr. Charles Schaap’s version of the indicator. In order to do so, the DM period is set to 13 and the ADX period to 8.
