Abstract: An exemplary aspect comprises receiving data related to an underlying asset; calculating values corresponding to near-term implied volatility and realized volatility for the underlying asset; and transmitting data sufficient to describe an index based on a difference between the values corresponding to the near-term implied volatility and the realized volatility for the underlying asset. Another exemplary aspect comprises receiving electronic data related to an underlying asset; calculating data sufficient to describe a plurality of call options and a plurality of put options related to the underlying asset and written on a first settlement date; crediting an account with proceeds from selling the call and put options; and debiting the account to settle one or more of the options that are in-the-money on a second settlement date. Other aspects are apparent from the description and claims.
