I acknowledge your market experience. I just think you are dismissive of things which ought not to be dismissed,

Fletch,
I have been reading this thread with interest, once again marveling at all the BS and naysaying provided by other posters to what could otherwise be a fascinating discussion.
However, as a winning poker player and trader, I can tell you emphatically that there are some things you are also "dismissing" as well that others have tried to clue you in on. Due to your inexperience with actual trading.
1) Math skills are not trading skills - this is evidenced by the fact that 80% of mutual fund managers can't even outperform the SP500, even though they have every conceivable resource for math, engineering, statistics - many of them have more degrees and skill than either of us, all to no avail. But I still outperform most all of them with my discretionary trading due to experience, not smarts. It took me about 5 years to master.
2) Before you tell me that discipline, self-control and dealing with fear/greed are going to be eliminated by mechanical trading, I'll just let you know that is wrong. Overoptimization, curve-fitting, inability to stick with a system during drawdowns and chronic re-engineering are the mechanical trader's Grail Hunts to deal with these very emotions - and it is actually very hard to create a robust mechanical system that forward-tests well under all market conditions and that won't get crushed by all of the other systems it is aligned against.
You could spend a year designing the perfect mechanical system for your little 2 or 10 contract trades and some hedge fund that trades 500 or 1000 at a shot has a system that by accidental design usually takes the other side of your trades, hence negating that same edge you thought you had. And they may only trade it in certain markets along with their 14 other black box systems, so it is very hard for you to adapt to it. (now multiply this phenomenon by 50 or 150 or 500 systems in play, depending which second in time we are speaking about) it makes trading very hard to quantify mathematically. The only math needed to trade well is good risk/reward ratio - 6th grade math.
3) When you play poker, you can read the whole table, there are not several hundred thousand other players waiting to impact "the hand" with 1 contract or 1000 in the next 2 seconds and with cards you have a finite combination of hands and odds. In the markets, the combos are exponentially limitless. Therefore "odds" by necessity becomes a more fluid term.
I hope you know I am trying to be part of the solution and not the problem.
Respectfully,
Paul
