Hello and welcome back, in this chapter we will continue developing our Forex and Stock application. We will create a method to plot the average directional movement index values. The average directional index (ADX) is a technical analysis indicator used by some traders to determine the strength of a trend. The trend can be either up or down, and this is shown by two accompanying indicators, the Negative Directional Indicator (-DI) and the Positive Directional Indicator (+DI).
Below is the modified version of the project with a plot adx button which will call the plot adx method after it has been clicked.

After running the above program below is what we will get.
