I have rarely been successful getting orders filled at the bid, unless of course the bid drops. If I don't care if it ever fills, vs making sure I get them, I place my buy at the ask and it fills immediately. The difference between our B/A is so small, it barely matters, especially long term. BLTA Thurs low .0149 with high .0164 matters not for 100K buy, but 1Mln...another matter.
