Interestiong debate... I often giggle to myslef when traders are arguing about what works and what does not..
The beauty of this game is that nobody is wrong, and nobody is right... strikes me as funny that people who have many years of experience in either camp cannot understand this ??
I cannot agree more.
haven't you people read market wizards 1&2?
I mean there are traders who win with mechanical system who stress how much discretionary plays dinged them in the past, and there are those who claim there is no way to make money without looking at the full picture fundamentally, others play tick by tick, other arbitrage etc. etc. etc.
there are lots of ways to make money, and remarks about mechanical system being curve fitting just shows ignorance of the subject, exactly the same as the "you can't learn anything from looking at screens" remark.
the holy grail is to find the way that fits your personality.
