in stocks it is nearly impossible
i do it in forex......
The problem is that on ET everybody sees things from his own, very narrow, perspective.
Daytrading for stocks is indeed not a good idea, but in forex or futures it is a completely different story.
And people who say that daytrading is a myth, probably never traded forex or futures. Or they did but failed.
Failure is no proof that something is impossible; it is only proof that for you it is impossible.
As most people have the subjective opinion that they are smarter then 90% of the population, they conclude that nobody can what they cannot.
