Optionwriter,
Suggest you search the thread for multiple discussions on SET risk etc. I know it's a long thread but spending a weekend reading the ENTIRE thread is well worth it. More specifically, last comments by Phil on the matter here:

Triple witching this exp so anything can happen lol. Will be an educational week even after FOMC
In general best not to hold till expiration unless a million miles away. Not worth it for the sake of saving some commissions. Timing when to roll or close can be a bit of an art.
Good luck.

Quote from optionwriter:
Coach - What criteria do you use whether to hold to settlement and let expire worthless or close position in last couple days?
I've taken a couple years off of credit spread trading and am easing back in.
I just reviewed the settlement procedures off the CBOE site, and was reminded settlement is based on opening price on Friday, not Thursday's close.
I'm currently holding 100 contracts on the Dec 1290/1305 call spread that I opened for a $.80 credit a few weeks ago.
I'm feeling pretty secure with this position, but say it gaps the next couple days and closes at 1285 on Thursday. Still 5 pts out of money, but risk of a > 5pt gap on Friday open would hurt.
Just curious as to you or others threshold for pain approaching expiration - thanks.
