Zeev: The "crims" move the price to motivate buying or selling. When the price starts running, many will chase it up or down depending on the move. The "crims" depend on this psychology. They also depend on those positioned against the price move to be motivated to cover and possible reverse their position depending on how dramatic the move.
However, there are times when volume does precede a move, but I personally find (or identify) those less often. When they do occur (at least the ones I spot) they are often executed in advance of the move to follow. An example of this, was the accumulation of IBM in late 1992 (see volume spikes) before it bottom in 1993. A look at the chart reveals what happened next.
Close is good enough when accumulating or distributing when you're holding the "price stamp" and you "know" where prices are heading...gg
