I don't want to crash anyone's dreams, but it is highly unlikely that there is a successful robot out there which can make money consistently. If, by any chance such robot existed, its owner would keep it hidden and make millions in secrecy. He would definitely not put it out there and sell it for a couple of hundreds of dollars. I mean, face it, if you had a successful robot, wouldn't you concentrate on making money in Forex and then go to the Bahamas, Bora Bora or some other beautiful destination and enjoy yourself? Would you bother to sell it worldwide for a peanuts? If you need to make money by selling some bot, then this bot is definitely not making money or, at least, not any significant amount. Otherwise, why bother?
