The markets bias is really to churn.
If you measured the up AND down movement in price all day long, every tick, and did the math on it, you'd find that even on a day where the market has a huge price increase, it's increase is pretty much dwarfed by the amount of churn that happens.
Said another way, a huge UP day is really UP, DOWN, DOWN, UP, DOWN, UP, UP, DOWN, UP (that's one more UP than DOWN for those counting at home). In the aggregate that means it went up, and chart traders care about that, but I'm not sure any scalpers do.
