around $20,000 is the minimum account balance that you need so that you can begin turning in a consistent $600 a month, I have used the most conservative figures since forex markets are very risky and you should not bet higher lots at higher leverage to fly higher, strops kill your account and given the kind of swings you get in currencies, it is easy to loose money faster than gaining it. so my view is that you need a $20,000 account if you wish to earn $600 a month consistently, sudden gains do not matter, long term consistent gains matter
