Sometimes I see this action on level II:
ask's are filled and bids are stepped up, then the price on the ask and bid drops $.04 or so for no apparent reason - WTF?
for example
b a
.88 .89
.88 .90
.88 .91
.87 .92
green orders go through on the tape (assuming all the sizes above are the same). Then an immediate change to
b a
.82 .83
.81 .83
.80 .83
etc.
what the hizzy is going on?
