Me too. In fact, I don’t believe it’s possible for any individual trader to place an order in the billions of dollars at one time. No way could that be possible in any Wall St. firm. The software on their workstations would reject an order of that size and they would not be able to override that rejection. This plunge could possibly have been caused by super fast high speed computer trading that just sent too many sell orders into the market too quickly for the market markers to respond fast enough, because as far as I know, buy orders from market makers are placed by real live people and not computers. That’s an alternate theory to the theory that the market makers didn’t properly implement the role they’re assigned in the stock market today.
Or, tin foil hat time, much like in Clancy’s “Debt of Honor” and engineered computer problem.
