Contract Specifications for RealVol SPY Options*



Underlying Index

The RealVol SPY Index. This index is based on the rolling, 21-trading-day realized volatility (adjusted for dividends and any market disruption events) of the daily closing prices of the SPDR® S&P 500® ETF (symbol SPY) as calculated by the RealVol Daily Formula.

Index Price

Volatility, which is typically expressed as a percentage, will be quoted without the percentage sign; e.g., 23.45% is quoted as 23.45.

Premium Quotation

Stated in points and fractions; one point equals $100. Minimum tick for series trading below $3 is 0.05 ($5.00); above $3 is 0.10 ($10.00).


Purchases of puts or calls with nine months or less until expiration must be paid for in full. Writers of uncovered puts or calls must deposit and maintain 100% of the option proceeds plus 20% of the aggregate contract value (current index value x $100) minus the amount by which the option is out-of-the-money, if any, subject to a minimum for calls of option proceeds plus 10% of the aggregate contract value and a minimum for puts of option proceeds plus 10% of the aggregate exercise price amount.

To calculate maintenance margin, current market value is used instead of option proceeds. Additional margin may be required pursuant to Exchange Rules.
