Hi, I'm sorry in advance for asking dumb questions. My broker (Interactive Brokers) doesn't list the Delta for VSTOXX V2TX Volatility Options on the Euro Stoxx 50. I know that the VIX options on the American Exchange are also constantly wrong because it goes off the Spot Index and not the futures. Where can I find a delta and gamma for the VSTOXX options? They are American style not European like Black-Scholes. Also is there a difference between a) VSTOXX® Options (OVS) and b) Options on VSTOXX® Futures (OVS2) I noticed there isn't this different types for the CME VIX Options. Thanks so much for your help.
