Correlated ETF funds

In this coding exercise, you will explore the relationship between two popular ETF funds, the SPDR S&P 500 (SPY) and Invesco QQQ, by creating a scatter plot that displays the correlation between their traded volumes. So, let's begin!

Two DataFrames named spy and qqq, which hold the historical prices of said funds, have been loaded for you. The DataFrames and Plots packages have been imported and are available for use.

Instructions
