If you're arbing QID with NQ then - how would you figure out how much of a move to expect in QID for every one point move in NQ?
Both basically based upon same underlying asset. Can't see how they could be arbed except for pennies and in the very shortest term.... hardly worth the effort for most.
Okay to be honest i was just phishing for an answer because I'm too lazy to figure it out myself. I have absolutely no interest in arbitrage.
