Here's a quote from ZeroHedge:
Silver is up over 17% from its intraday lows today - this is the biggest positive swing since our data began. All the previous major swings have been downshifts, most recently in September 2011 (-22% and -18% over 2 days). Volume is very high also. Gold is back above $1,210,up over $70 from its intraday lows...Those who where planning to bottom fish had a very narrow opportunity both in terms of market depth and duration of the window in the middle of the night in the Asian hours.
Here are the screenshots (they do not show the Asian hours).
