Quote from coolweb:
What was interesting was you bought @ 201, but was the bid @ $205 the moment you bought right after?
That spread must have been huge if it was like that
At that moment all bids/asks on Level 2 were invalid. They were far from the time&sales prints. I went by the prints... which fluctuated between 204.xx and 202.xx, up and down by a dollar in every tick. I entered my limit-price orders just to see what happens.
I remember a day like this once: 9/18/2008
Goldman Sache, GS, went from $115 down to $85 in the morning, then bounced back to $120 in the afternoon.
