Are you also in the habit of shouting "FIRE!" in theaters?  

The more interesting data for comparison, I think, is actually what volume tends to be during calm periods. It makes no sense to compare the present volume to what the volume was at the beginning of a giant price spike.

I should also point out that this hypothesis horribly fails backtesting, considering that we did indeed have a "crash" less than two weeks ago and nevertheless continued upward movement on increasingly thin volume.
