This is simple economics. As someone else stated, if this worked at all, you would have poured all of your resources into investing your own money or starting a fund to manage others' money. If you could beat the market by just 5%, you would be a billionaire within a very short amount of time as everyone would bring you their money. Instead, you decided to build a website and sell it to others for $20 per month. Surely as someone so knowledgeable in markets, you realize that selling something so valuable for so little would not happen.
I stand by my statement - your product is false hope and is a scam, as all of these systems are. Some sucker who doesn't understand that the best move is to just buy the broad market an hold reads your marketing, buys it, and pays you. What you've sold him is certainly not the ability to make more money. You and I know he won't do that unless by pure luck. What you've sold him is a sense of hope that he will make money, and the ones who often fall for this do so because they've gotten themselves into financial problems with trading and want to believe that this is the system that will fix it all for them. That hope is a very addictive drug that will last as long as he can hold on to the lie.
If you're ok with that being your business model, that's your right. It isn't illegal. In my opinion, however, our society is completely overloaded with people who take advantage of others while adding zero value.
