I have no idea how this got filled at 3.70 credit! Its mid price was 3.25 credit, but it got filled in seconds! I had a limit order in for 3.60 credit and actually received price improvement.

So, this is a low risk loss wise $SPX In the money bear call spread for next week expiry. Max gain is $370 per lot if spx below 1650, and max loss is $130 per lot if above 1655.

Sold to open july20 $SPX 1650 call
