I think that sounds like it is really profitable but I think that's not really true. Often times I heard horrible stories about trading, especially from the newbies, while those who already gained enough experience can only earn sufficient amounts to recover what they have risk and there can only be rare times where they can earn a really good profits. It's either they get lucky or the market is in really good shape.

Of course we can, I mean it is possible but it is not advisable because this is an act of greediness and usually, we can only make another loss after the other. It is like there is a curse on it but a scientific explanation is we are not yet prepared (i.e. we lack in analysis).
