What I really want to do is to check the margin difference if I close all these positions but so far I haven't found a way to do so programatically.
That's probably the other reason they don't allow it, the orders you included don't margin against each other well.??
In this case, you're best off with a +4 and -1 call spread..? and then the long puts as a second order.? And then add the margin's from each.??
