From a daytraders perspective, it's not as simple as you make it out to be. Friday price oscillation with size was met by opposing size. I bet lot of systems lost money yesterday with the multitude of false signals that were generated throughout the day. That's not even counting the last 15 minute whiplash.

Hello:
I guess if you got your ass whipped it is natural to talk about how the other guy was much bigger (stronger, faster, etc) than you.
Fact is you folks had choices to make, and apparently you made the wrong ones this time.
I am all done taking care of the children on the site, but for those adults still around, you may want to THINK about this a bit;
When a locomotive goes by, there are several kinds of air flow that proceed and ACCOMPANY it. Just in front of the nose of the machine, you have a form of turbulent flow. Depending on the size and configuration of the machine, and its velocity, that turbulent flow forms a wake that LEADS the machine by some distance "X". As the locomotive goes by, if you had the right measurement tools, you could see laminar flow across the nose and leading edges of the machine, and as it CONTINUES ON, the body creates a vacuum right at the tail end. At the fringes of this vacuum is (again) turbulent flow. Strangely enough these characteristics (called fluid dynamics) also apply to the example of big order flow moving markets.
In addition, when that locomotive goes by, generally the damn whistle is blowing, and the ground is shaking, and the rails start to vibrate. As kids, we used to put our ears to the rail to try to detect that vibration. Then we would put a few coins on it and watch them get deformed by the wheels.
So there seems to be all these cues that proceed the train. Some by quite a distance, and yet every so often some idiot, wearing headphones, is caught walking down the tracks with his back to the train, and he or she gets turned into instant hamburger.
So I am wondering why it is, that with all the possible ways to detect the train (trade volume) coming at them, that they don't either step off the tracks, or if they want to ride along, go to one of the whistle stops and just get on board.
