Quote from MajorUrsa:
Of course you get filled when you take the middle between b/a, everybody does, that's no secret. All markets work that way, why would SPX be different?
Ursa..
Showed me how dumb you are? Why do you inflict yourself to this kind of answers? You have admitted you never traded SPX, so you don't even know what happens when you trade SPX?
Why are you exercising your puny little brain aganist mine? Obviously you are no match in any form and shape. You have been explicitly told to GET LOST, but like a shameless beast you keep rubbing your head againt a stonewall time and again.
