I hear you, but is your "flow" trading state possible to code as a logical algorithm or a set of conscious rules or it is mostly unconscious process?
For your own answer consult certainly one of most intelligent people IMO on this board - Nitro - where he said "Because otherwise P=NP." I think I understood what he meant while some did not but my own thought was around this Turing machine subject:
http://en.wikipedia.org/wiki/P_versus_NP_problem
It was a brilliant insight for traders who really think deeply and provided some evidence for my own thoughts about investing/trading theory.
Some simplified thoughts (please keep in mind they are hypotheses and opinions and not proven for me yet.)
An edge is an inefficiency in the market. The strong eat what they kill (mostly the weak).
Technical Analysis started failing many decades ago. Program trading arose to defeat it.
Many years ago program trading was popular when large firms had better quality tools than amateurs and amateurs were fewer in number. Specialists were the hammer.
In the 90s that changed as smaller traders TEMPORARILY gained enormous computing power and could game the pros with better information and faster timing. Amateurs were the hammer.
Prop shops then arose where pros gamed large numbers of amateurs that believed in TA essentially by painting TA indicators since they had better indicators and ties to the heart of the market - specialists who wanted their hammer back.
Amateurs moved to daytrading. TA indicators started completely losing their power as information was disseminated. The Edge of the big shops and prop shops was lessened. (Such is the nature of markets. There is an astounding indicator that shows this clearly since about 2005 which will remain secret until someone else raises it first).
Prop shops died to HFT who gained a market inefficiency by regulation. Curious that that has never been corrected IMO - do the legislators not know what to move to now?
HFT are savaging HFT now. Michael Lewis spilled the beans and the weaker traders fled.
Something even worse is appearing (that will defeat HFT) and traders must adapt yet again. This particular though very preliminary for me and will not be clarified because it could be a future edge for me.
Market change. Markets stay the same. And change always appears from the fringes (as it must):

So in short, in the very early days hard edges existed as market inefficiencies but already in the early 90s I realized that computers had limited shelf life in trading and it is my opinion that discretionary trumps system ultimately. That is why I have steered that course from early on in my own investing/trading.
Interesting you would ask about this as CERN is being restarted. Will rainbow gravity be found or the Big Bang or will Nitro absolutely be proven correct in his brilliant brilliant insight. BYW consciousness itself doesn't play a role in our models of physics - a rather glaring omission don't you think? Recall even our physics requires an observer - a piece of discretion that makes the system work. So IMO, computers will NEVER be intelligent and CAN never be conscious.
If consciousness is required to trade and win, then all systems have some discretion don't they?
Hopefully that answer it. Sorry for the length of the post.
