I have no idea.. but if you call your broker and place order, your broker can call MMs and tell them. That's I know. For Freetrade (ameritrade division) I can't call my broker to tell them anything. Also when Bid x ASK is at .0001 x .0003, my order at .0002 don't get filled that is normal. They have no obligation to fill my order if it's not at ASK. But some people got filled at .0002, it is just not fair. Then again, who said the market is fair, especially in pinks.
