Dan I just proved your theory doesn't work, I kept upping my bid, they filled me at the highest point then dropped both bid and ask. So I paid top dollar for my shares when I could've bought them at the current ask for a discount If I just "sat" there.
Lesson for me learned when I have a bid order in DON'T TOUCH IT!
Dan explain to me and the rest of the team how MM's make money by lowering the share price. I was under the assumption that MM's made money off the spread.
