Well then, someone really didn't want those 8787 DRK anymore...
Same thing happened at the same time yesterday. Real conserted effort going on here. One or two people panicking I get, but when these red candles show up periodically for weeks -- standing out as outliers given the market volume, even after RC4 improvements have been made clear... Yeah, something's up.
Where are you seeing large trades? I see very little volume at all, certainly no huge trades like that today???
