I do and have for years. I went from short term trading(minutes) to more long term trades based on day, week and monthly charts.
I've posted a few trades in here when I saw them developing and they did very well. I was going to post one on the Eur/US in the middle of December but never got around to it.
IMO it's pretty easy to trade with good results but much like Hold em you have to have rules and stick with the rules. Most people can't do it and take 1 or 2 chances here and there and that's enough to do you in. In about 10 years when both of my children are off to college my wife and I are planning to move to another country(Mexico right now) and at that point I'll start trading full time.
