VIX 2 - Monthly picture CBOE S&P 500 VIX CBOE:VI2! yacine.kanoun Smooth index trading occurs when VI2 trades between 12 and 18. Above 18, everything becomes possible. We have been trading a few weeks above that level for a few weeks. The question is what happens next week. You know my opinion by now: I think VIX will remain supported even if equities slide up.
