Rolled the $SPX calendar into a 10/4 4400/15/30 call BF, for additional $4. credit.
The original position was started as 10/4 9/29, 4400 call calendar for $13.9. Rolled the short legs twice, for an average 7.5 credit total. (badly managed and missed some opportunities during the short-lived pops, or could have the cost more than covered by now).
Turning it into a BF reduced the risk of holding the long leg from 4.8 to 0.8.
The remaining position has a net cost of 2.4, ok for a 15 wide BF.
