I think that the main issue has to be, a Trader specifying his Monthly limit. That is to say, "I will earn from 500 dollars monthly", and just with that...he will be working hard to earn above it every month because that is his plan, so he has to stick to that. Moreover, he will always trade when the Market condition is ok for him to profit and will avoid some common mistakes because of his monthly limit.The monthly return earn by traders varies from traders to traders not doubt but no how you try here to earn I can tell you that you wont be earning a fixed income on monthly basis there are some month which you will have deduction and some month you get earn big
