it seem somebody took huge positions which drove the price up then pulled out what seems to be the entire amount out which brought it down faster than it went up. . At any rate, i love bear markets because I buy in near the bottom and make a killing margin trading.
That said, this mornings was the largest flash crash to date. It was definitely not individual traders making the market move like that.
Im am not irrational. I am full time trader and thus highly analytical.
