Plotting the Chaikin AD line graph

Our Own Score

In this chapter, we will create a method to plot the Chaikin AD line graph with the help from the alpha vantage module. The Accumulation Distribution Line (ADL) is used by Chaikin Oscillator to measure the movements of a stock.

We will include a button to call the plot ad method to plot the AD line graph.

Anticipating trend changes in the Accumulation Distribution Line can help chartists anticipate trend changes in the underlying security.

Let us take a look at the Chaikin AD line of one the stocks below within the time interval of 60 minutes.

I am thinking of putting this project online soon and this project will get updated weekly with the latest feature, so stay tune. Like, share or follow me on Twitter if you want more Forex and Stock programming tips.
