That's interesting.... What's your experience been placing relatively size buy orders in below or sells above the market on low volume stocks? I get the feeling those visible orders are used as floors or ceilings and are traded around by MM and others.... Sometimes you can catch a break and buy low or sell high if an early in the day market order is placed by the naive, but most of the time, it seems as though the order is essentially shopped.
I never show my hand prior. Place the sell order on que for the stock I just bought and the buy order in que for a placed sell. When the time is right move the price as needed - pull the trigger - need real time quotes for anyone serious about trading. Computers doing nothing but adding up all the bids and asks and always going with 50.01 swing to their favor.
