I definitely wouldn't call Forex a get rich quick scheme by any means. However, after growing your account for long enough, trading 20 or 30 lots will start adding up if your strategy is sound.
Forex is risky work, if we can not control our trading then how we can expect that a robot, a written program is going to earn us money and going to give us a profit for nothing.Of course and that is the main reason, why I prefer manual Trading, as the Forex Robots, grab control from our hands and I prefer to have control of my trades in my hands.
