I had a standing order to buy long the same quantity for two days in a row that was never filled. I saw plenty of trades those days @ the predictable .0002 to .0003 and for quantities more than and less than my order. I had entered my order as a "Limit" order to buy @ .0002 and not at "Market" with TD Ameritrade. When I called TD to ask why my order wasn't filled, they told me the market makers were selling at .0003 and buying @ .0002, therefore my "limit order to buy" wasn't met.
It appears the ones making the .0001 difference is the market makers. If my figures are correct, since 8-6-09 until 8-31-09 the MM have turned just over 3413 billion shares at a profit of .0001 and made a nice tidy sum of $341,300.
