There are many ways to trade the markets successfully and consistently, but what works for one trader does not necessarily work for another and so on.
Much more has to do with the midset of the trader, than the actual method itself. If it was all down to method, then anyone could trade any method equally as well as anyone else trading it successfully, but it has been shown time and time again that this does not follow.
Psychologically, some people can hang in for the entire trend, others get shaken out. Some can scalp pennies, others can't. This has less to do with skill levels, but more familiarity with doing it and the right mindset/mental make-up to actually do that type of trading.
No-one can teach you this mental aspect of trading, only over time can you learn it for yourself.
