Professional day trader. (as long as I was good at it )
Actually I did day trading for several months back in 2005 and made several thousand dollars... Then I lost it all in (no joke) 5 seconds on a stock that totally hit the floor literally right after I got in. I actually watched the realtime graph plummet.
So yeah, as long as I didn't buy those kinds of stocks and only bought the ones that I made money with..
