Oh, Ok. Why should you never pay for training?
Because there is nothing that they will teach you that you cannot teach yourself very easily from well known and widely available books. In fact you can easily get yourself streets ahead of where they'll get you just by studying a few good books and everything in the knowledge labs here.
People shouldn't be under the impression that a course, however good the reputation of the firm, will immediately get them trading profitably. There are no shortcuts, holy grails or magic formulas, and to be quite honest most trainers are trainers not traders for a reason. The initial training is just the first step on the long hard road to profitable trading.
Also, perhaps more importantly, if you're going to be trading their money (Or hoping to if they think you've got potential after the training) then you want to be with a company who's income comes from successful trading not one who makes their money running trading courses regardless of how successful the traders become.
