What you look for at this point is...
A QE or the like that the market has been front-run with Insiders to the point that the (whatever)market does not respond...and, in fact, reverses.
This is what the Fed is trying to avoid. That is, a move designed to keep the status-quo that is so saturated with insiders that you get a failure in the market(s).
So, this is what to watch for.
