Understanding the Slope of Moving Averages

When analyzing financial data, understanding the trends and slopes of moving averages can provide critical insights. If you've ever tried calculating the slope of a moving average's endpoints in Python, you may have faced challenges, especially if your results don't seem correct.

In this guide, we'll delve into how you can accurately compute the slope of moving averages using Python, ensuring that you get reliable results each time.

The Problem to Solve

You are trying to fetch market data and calculate its moving average using the Marketstack API. Once you've calculated the moving average, you want to find the slope between its starting and ending points. However, you noticed that the results you obtained were not matching your expectations based on manual calculations.

Your Attempt

Here's a brief look at the code you provided:
