Does anyone know if any of the financial sites let you make it watchlist with a purchase price, so you can monitor where things are from a certain base runner then just yesterday?

My interest is largely educational, as I?m trying to just pay attention to world news in financial stuff, and maybe get ready to take online a course in Investing, mostly just to understand. And there?s online micro and macroeconomics courses that I missed in college. Would anyone recommend direction?
