Quote from andysmith:
It's almost as if the MM knows the direction the market will take for the few weeks after my fill, and won't let me in easily if I'm directionally correct and will fill me quickly if I'm directionally wrong... Any thoughts?
How about something simpler: The MM may fill your order because it's a spread he wants for his own portfolio. Perhaps because he believes you are 'directionally wrong' or perhaps because it may reduce his risk by balancing some greeks in positions he owns. There is also the possibility that your spread, coupled with other orders currently offered allows him to lock in a great price for a box or a jelly roll etc.
