Stop losses. Also, don't over-utilize your leverage. There are many people living off forex, but most who try blow up because they don't manage their risk exposure.
I know there are people who make money out of forex but they are getting less and less in the longer time frame.
While the winners are %20 in a 3 months time frame, they are %0.22 in 3 years. You know why? Because they played too long.
Things really get messy with forex. Forex players will never agree with this but its gambling and definitely not a job.
You can say; there isn't a guaranteed job neither, people lose their jobs too. And that's where i get confused. A bit.
I guess it can be a job as long as you make money:)
