I am a swing trader, long term investor...I started investing with a Motley Fool Special Ops subscription back in 2010-2011. I still consider myself somewhat of a newbie. I know the basics like support and resistance but I really need to learn more (gotta study Tim's DVD's). Coming from a long term investing newsletter has taught me to have patience. Cutting losses quickly sounds like a simple thing to do but sometimes I break my own rules and become an investor (or bag holder) rather than a trader.
Update 3/11/15 : have since completed a Steve Nison candlestick course and a Bulls on Wall Street Boot Camp (I highly recommend both if you want to have a solid foundation).
