Well I have never seen anyone saying that before, how can one possibly say that wining means that they will no experience losses. I think the person must be a joker because I don't see any possiblity in that, and yeah those that claims to be an expert in terms of trading still encounter lose sometimes you will see them posting winings all over thier status and those that doesn't know how trading works will be thinking that they're indeed an expert that they don't always experience lose.

 the truth is losing is always bitter, that is the reason why people like hiding it but when you see them celebrating over their winings you will feel that they have never encounter lose ever since they started trading because they celebrate in a big way, but when you look at thier history/ record then you will see that trading is a very risky game.
