Today's dramatically different 1-minute chart. Compare those gigantic volume 1-minute candles (like the one showing over 200,000 shares traded in that 1 minute) to the usual ones, where even a 5 or 10k share trade is unusual.

NOTE: This is a dynamic chart, showing as I post it the Tuesday 12/15 and Weds. 12/16 chart. If you click on it on Thursday, the Wednesday chart will be on the left side, not the right side.
