A commercial such as a big retail bank with an investment division creates a daytrading algo that works consistently. It only works with a limited capital, like most algos. Too much capital and it becomes detectable and countered by other algos. The bank takes it's algo and puts it on collective 2. It allows no subscribers for 2 years. The algo is proving profitable with very low risk. All of a sudden, the automated trading system is accepting subscribers at a low cost. People jump on it. What happens next. The algo works as it always has, sends out buy/sell signals and they are profitable. It becomes popular enough that the C2 subscribers make it's moves more detectable. Thus it starts becoming less profitable over the months. The commercial however earns more. How? They post the signals a short time (20 seconds) after they are generated. This makes the subscribers push the price up/down a bit in the favour of the algo, in a way making the algo the front-runner. The subscribers end up getting near to 0% returns over time, but the commercial is happy. The premise is of course that it gathers enough subscribers and that the algo knows how/when it's best to publish a signal and still make no major losses for the subscribers. With a sustained 0% subscribers won't bail so soon, because hey, after all the algo has 2 years of success behind it, so maybe if they just wait a little while longer it will make them rich.
