13 period weighted moving avg of volume vs SPX

Overlaying a chart of a front weighted 13 period moving avg of volume over the SPX  reveals (to my way of seeing it) the choking off of free markets by the fed.  The higher they artificially lift prices the longer oxygen is deprived from the free market until it eventually dies off. (volume will continue to collapse) Should the fed release it's grip around the neck of the market in time prices will surely collapse but will eventually survive.
