Like I said, I played to my strengths. I dont doubt that people can find edges using other methods. (Although I suspect it is much harder to prove such a method works compared to my methods. I can dump a pile of data on your desk that would leave 0 doubt in anyones mind. Absolutely zero.)
After all, the brain is an incredible pattern matching computer. We can peer at a face and recognize it instantly, while a super computer could take minutes or hours to do what we consider a trivial task. The flip side of this is, the brain also frequently see's patterns that are not really there. Fooled by randomness, is a frequent occurence.
But, big but, the moment you step outside of the purely mechanical domain, you must also deal with emotional control and discipline to a huge extent. Something which is easy for me. I just watch the computer trade.
Knowing myself, and knowing how thin edges can be, which allow no room for error, I do not believe I have the emotional control and discipline to consistently play every trade perfectly according to plan. I am flawed.
Knowing this weakness in myself, and knowing my strengths, is what eventually forced me to choose my path of super analytical number crunching and pure automated system trading.
I decided to play in the automated space, where I could use my skills to beat the other players also playing the automated space.
I just hope for you, that markets dont get so damn efficient, that the compass stops working. I may have a GPS, but I know for a fact there are guys out there with military grade GPS's which are far more accurate than mine
But for now, GPS is good enough, and the opportunity cost of upgrading to military GPS is too great for me. Maybe one day that will come.
In all reality, trading really can be simple as downriver describes. Thank God for that, or I wouldn't have had a chance in heck! While I do admire what you accomplished systematically (speaking as one who's been deep, deep in those trenches) I am also happy to say there are those of us still steering our ships by compass instead of GPS.
