Hi,Quote from clarodina:
Does futures vix converge to cash vix level on option expiration and the cash vix level is used to calculate whether the option is in or out of money? But the historical data of vix futures front month is always out of line on the settlement day at option expiration so which 1 is used for in or out of money option?
Anyone know any brokers that offer binary options?
Yes, I believe futures vix should basically converge to cash vix... but this is only approximation. On expiration day, they do a single sample of option prices at the open to generate the final vix future price (special opening quotation). This should basically be spot vix, but might not actually be identical.
What numbers are you looking at that you think they're actually different...?
