Just curious.
Did you look at the SPX as an alternative for the 1220/1210 July put spread. Current midpoint is $0.85, but I have noticed that lately the SPX midpoint on ToS is pretty much meaningless. I can't get filled on anything lately (August) even going $0.10 below the midpoint.
I'm looking at the mid vs. the theoretical price using TOS. There is definately a good sized difference between the two in many cases. I tried to get a fill that was .10 under the theo price and .25 under the mid and no luck.
