If you do not have L2 or don't know how BKMP trades I suggest you trade long on BKMP. I use ETRADE L2 when I am at home and it tells me when (date and time) bids were submitted. And USUALLY its first in\first out all other factors being equal. I have had bids in at .0004, .0003, and .0002 as GOOD TILL CANCELLED LIMIT orders for two to three weeks. That usually pushes my orders to the top of the fill list, but it does have its drawbacks.
