I don't have any actual knowledge or proof, however from my experience, this won't help. The MMs have to make the market no matter how high you set the GTC order. If you set it real high, they can see it as well, they have their own game plan in any situation. There were times when I saw the stock's float was being owned, and in fact the whole OS was being held, and the MMs still whack it down... some of these stocks might come back, only after a long period of time and what I know is that they can pass shares to each others, and they don't need to cover every month or whatever time period people think they need to cover... law = no use. Forget about the law and follow the real game law is the only way to prosper in bb stocks.
