Any group with such a low percentage rate of success is not going to be a good one. They will say that "trading is a tough game", it is extremely hard to make it, you have to be good, bla bla bla. Trading is difficult at shops like this that have no knowledge to teach.
Good groups have much higher rates of success to the tune of 75% and upwards. If they had good training and people that knew how to trade the markets they trade to teach others, and hired quality people, they would have a much higher rate of success. Bottom line.
Besides that, the fact that they are not offering any salary or any benefits whatsoever should tell you that theyre not worth your trouble. I dont know of a single successful group that is set up like that.
