#SPX0dte I did a mini-study today to back test WAITING UNTIL EXPIRATION . I went from April 5, 2021, which was the first day we breached SPX 4000, to 2/13/24. I tested the IB with 30-pt wings. Premium taken in of $16 each day.

Total trading days:721

Total wins: 276, $2,370
Total losses: 445, -$5,147

So, definitely not looking beneficial over long term to wait until the close. I suspected this, but wanted to make sure. If we increased premium to $17 or $18 we’d get closer to even but I still think it would be a loss.
