You'll want quotes from both exchanges for those SSF that trade on both. Unless you decide you like one exchange better than the other. You'll just need to route your closing order to the same exchange you opened it on. Otherwise, you'll be left with one long and one short position on the same SSF.
Although (at Interactive Brokers at least), if you do establish a long and short position on the same expiration date of an SSF (you would need to do that on two exchanges), your margin requirements are 10%, instead of the usual 20%.
It's worth thinking about. Could be a useful strategy. Like having a call and a put option on the same stock, without the time-decay?
