actually it was the "electronic" platform that was down, The SPX is open outcry Arnie so you still could have been filled.
Well, it would have been a profitable trade so far... I wanted to write the 1345 Nov Puts, and buy the 1335 Nov Puts. At the time the spread was .35, and that was my limit. Then I changed the limit to .30, still no fill... Ah, no big deal... Greeks? What are those? Arnie
I used to work at the trade desk of a moderate sized broker. When we would see our electronic orders start to back up and not deliver into the CBOE's system (known as RAES) a collective "Oh $ hit" would be yelled to each other, the next few hours would suck. Ask your broker what they do when an exchange is down. We had a back up destination for every option, so, if the CBOE went down we would modify a field in our system and all the CBOE order flow would shoot down to the ISE (if it traded on the ISE).
