Doug, that's interesting: illegal to post a bid that is higher than the ask? What is the illegal part: (1) my placiong a bid higher than the ask or (2) a mm posting that bid?

Dave

There is nothing inherently illegal about locking or crossing the inside market during regular trading hours. A market maker can cross/lock inside market if he has a large size order and he has sufficient reasons to believe that the current inside quotes will not be able to fill his order.

A hypothetical illustration:
DELL 67 x 67 1/8
GSCO on the inside bid, size 10, MSCO at the offer, size 15.
A big client suddenly calls Goldman and want to buy 90k at the market immediately, giving GSCO no discretion (rarely happens in real life, but I am using it just for the example).
GSCO can raise the bid to 67 1/8, showing size 900, locking the market.
Or GSCO can raise the bid to 67 1/4 or even 3/8, showing size 900, crossing the market momentarily. Of course this will take out MSCO at 1/8 in seconds unless the latter has a much larger reserve size at 1/8.
