I do, and a number of people I work with also trade for a living.
A couple of things they have in common:
- At least 3 years trading experience
- Target a minimum of 20 pip profit targets
- Trade the London/US sessions
- Most have employed the use of a mentor when starting.
It's not easy, and most people don't have the emotional stability to do it. But I can tell you that there are plenty of people out there making good money trading FX.
