Quote from Merovingian:
I seek to understand the reasons 90% fail nomatter what system the are using (technical, fundemantal, tea leaves, whatever).
So looking at the market simply as a wealth building machine, it inclines a trader to chase whatever the hot stock/newest fab system is and looking to make a fast buck.
Your "question" is difficult to answer, because you couched it in terms of a statement; and one with many assumptions built in; some of which are incorrect.
Taking the first one; i.e.:
"90% fail no matter what the SYSTEM"....
First, 95% of those "invested" in the market don't even have or use a system. Of the remaining 5% who actually seriously do use a system; I'd wager that far less than 90% are losing. Probably only 50%, or even less.
It's unclear whether you are speaking of the whole world population, or just active traders.
On the second item; you use the word "trader", but then describe an approach which sounds much more like Joe 6-Pack "investing".
Nothing "inclines" a trader to do anything. That is a 180-degrees backwards view of life...a denial of self-responsibility for one's own actions.
Anything a person does is THEIR choice...THEIR responsibility; not the market's, not the gubmint's, etc..
And again, if you're talking about the general world population, then yes, I suppose "90%" do make bad choices in the market, approach things in a random and chaotic manner, etc..
But you also use the word "trader"; which implies a very much reduced and very specific subset of "everyone"; ....and there your assumptions break down.
In my opinion, the -only- sane way for a trader to look at "the market" is indeed as a wealth-building machine.
Like any piece of complex and powerful machinery, it requires one to study the operations-manual, avoid sticking one's hands in certain places, operate it only at safe speeds, etc..
But it truly is a "machine", and to a TRADER, building wealth is certainly the primary overriding factor in owning and operating it.
Around the house here, we call it the "nickel-machine".
As far as your "question", or statement really, the best answer I can give you is: it doesn't matter "how it works".
You don't need to know how a vehicle "works" inside, in order to drive it, eh?
All that matters is your pattern-recognition ability and your discipline as applied to entry, exit, and cash/risk management.
Due to ten thousand different variables, the market moves in a (relatively) small set of patterns; a number of which have fairly high odds of "completing" rather than failing.
I have no idea what all the variables are, nor do I know how to "model" them....but I don't -need- to know those things. All I need to be able to do is -recognize- a pattern as it forms.
This is why IQ isn't necessarily related to trading success. Perhaps those with excellent inherited -hunting- skills do best!
I.e., those who are best at spotting the tiger lurking in the trees.... It's all about pattern-recognition; coupled with timing and discipline.
Sorry if this wasn't what you were looking for as an "answer"...
