#SPXcampaign In pre-market, Bought to close $SPX July 1st 2150 short calls for .05. Sold as the 2150/2175 call spread for 3.95 on May 25th. This was an oversized position sold as a roll (14 contracts). By closing the shorts and leaving the longs in place, this released $86K in margin for today! Portfolio margin can be your friend, but it can also throw your account out of whack if you are too heavy on one side of the market. This reflects my oversized short-market position with call spreads.
