Look here. On around the 5 and 6th of November we had a big drop on low volume. The next day we had a big increase on high volume. Didn't have a big volume down day in that reversal. What you are saying is often the case but it doesn't have to be. That reversal did not have a high volume down day.
Also which may be to our advantage here, Williams % looks like it is coming off over sold like it did on the 5th and 6th so we MAY be reversing up here.
