like nephalim said the bigger your account the less you have to risk to make more money. It is the little guy with 1000 dollars, that enters this game thinking of striking gold based on hyped up systems that suffers the most. The leveraging kills you, and over time a vast majority fail. So the thing is to learn the rules, read up on the psychology bit and Money management and then risk no more than 1-2% per trade. the problem is that with a small acoount there really is no quick cash and that prompts newbees to play it risky. this coupled with the damn brokers ensures that the odds are really stacked against you. The easiest part is to buy a system, they are a dime a dozen. Concentrate on the basics and you will have a chance. jump staright into the big game and things can be dangerous
Best of luck
