| Mark Price | Options Mark Price is calculated in real-time by using the Black-Scholes model. The implied volatility used to calculate Options Mark Price is derived from the best bid and best ask prices for the option contract, along with the volatility cap and volatility floor set in the system. Implied Volatility = {max[min(implied volatility of best bid, volatility cap), volatility floor] + max[min(implied volatility of best ask, volatility cap), volatility floor]} * 0.5 The volatility cap and volatility floor might be adjusted without notification during severe market volatility. The option’s underlying price comes from the corresponding Spot Price Index before the settlement. For option contracts that settle in 0.5 hour, the underlying price is the arithmetic mean of the Spot Price Index during the 0.5 hour preceding the expiration time as indexed by the platform. |
