Just a quick repo outlining some work I did to scrape NASDAQ using the rvest pacakge for R. I wanted to memorialize that work here.
Also - I did some forecasting of the stocks using Facebook's Prophet package. I picked which stocks to forecast by fitting a simple linear model to each stock and looking at which had the most positive slope (increasing fastest) and the most linear trend (highest R-Squared value). To do that quickly, I used purrr.
