igor, i am sorry I am getting confused by the expiration dates. May1, May2 or May etc. its not quite the same on IBKR
May SPX for me is May 19th and my 2145 short strike is 14.
May3 SPX for me is May13th and my 2130 short strike is 18
May (may 19th) BPS is showing 0.3 to close 1870/1880
June 1 (june 3rd) BPS is showing 0.4 to close after 1 day.
I think the mid weeklies may have messed up the May1, may 2 labelling?
