not necessarily . . but I do use the $XII as a Technical Analysis Tool for some confirmation as well. The Big Boys are the Market Makers who control the action "on the floor" . . . and the money behind them. They're the ones who see your stops in place and the real supply/demand picture. They know how easily the Market will move in a certain direction and for how long . . . and they can see how hard it would be to take the Market past certain levels. So, they're the ones that make the waves .. according to the demands of the public and their psychology.
