Plotting the average directional movement index rating line with python

Our Own Score

In this chapter, we will create the plot adxr method in the ongoing Forex and Stock application project to plot the average directional movement index rating line. The Average Directional Movement Index Rating (ADXR) measures the strength of the Average Directional Movement Index (ADX). It’s calculated by taking the average of the current ADX and the ADX from one time period before (time periods can vary, but the most typical period used is 14 days).

Below is the modified version of the program. We have included a new plot adxr method as well as the plot adxr button which will be used to call the plot adxr method.

As usual run the program and then click on the plot adxr button we will see this outcome.
