Seems like the usual b.s. to me. Guys claim to have invented a trading system to make money. Hardly original. Perhaps they have, most likely they haven't, not in the sense it'll come good over the long run. So, do they decide to just keep it to themselves and make tons of money month after month ? No. They decide to sell the idea to 5000 others at $10/go. Why ? If their system is that good, they've no need of $50,000.
How about my system. Play roulette, bet £1,000 on the number 4 the first time. When it wins, put all your winnings on the number 7, then all the winnings from that on number 29. Makes you a fortune. I did it once, won masses of money. OK, I'm lying here, I've never done it. BUT, even if I had, would you give me £10 for the idea, knowing there's no way it would work long term (and I know that, which is why I'm flogging the idea to you for £10) ?
