Well - at least LeeLoo is honest and upfront about this. It says so on their web page very clearly and you wouldn't even need to ask them. I believe OneUp does the same, but they're not as explicit stating it. Earn2Trade also have what they call LiveSim, which I believe is the same thing.
They know the failure rate is very high and if a trader manages to get funded, they know it's likely he'll blow out before generating profits in his real account. So why bother funding him?
If, however, he should be able to make profits, he will be paid out of the company's own pockets which generate income from subscription fees and failed traders trying again and again.
This does however raise a few concerns:
1. What if you make a huge windfall profit? Just by chance - some trader would eventually come along who makes a huge profit simply by luck. Would they have money to pay you then if your trade never was 'copied'?
Actually, this happened with some other guy and was mentioned on this forum. I believe it was an FX firm. He made a really big profit. 200-300K. And he was not paid last time I checked and was taking legal action.
Split across all these firms which there are a lot of by now. Is there really that much money in selling subscription fees?
2. There's a win/lose relationship between you and the firm. It's not really in their interest that you make money as they would have to pay you out of their own pockets.
All of this is good to keep in mind. I think these companies can be an opportunity for a good trader to turn a $300 one time payment for a subscription into 8-10K of profits which is what you're getting paid initially without a split, but at that point it's time to say goodbye as they're not really funding you but allowing you to continue risking your own profits for a profit split.
I have never heard about anyone who's actually funded with these firms, i.e., "Go ahead, withdraw your 10K of profits. We'll continue to back you with a bigger account." At best, they just give you $5K of margin. Beyond that point you're risking your own profits.
