It makes sense, especially because my eyes were not glued to the screen, watching every single trade. I missed some of the action...was interrupted along the way.
When I WAS watching, the .163 ask was getting slapped but saw no selling into the .160 bid. I looked away for a moment and came back to see the bid drop to .1575 causing confusion on my part >> Huh? What? folks aren't selling into .160 so the bidder drops the bid?????? Thanks.
