Electronic = Volatility set to equal the mid-market price of an option. * Computed using midpoint bid/offer data from each options market and midpoint bid/offer data from the underlying futures market. * An implied electronic market volatility is computed for each strike price with a bid and offer. * One-sided markets are ignored.

Settles = Volatility set to equal the settlement price of an option. * Uses the option settlement price in conjunction with the futures settlement price. * A settlement volatility is computed for each strike price with a posted settlement.

Note: If you want to exclude Electronic or Settlement values below a certain value, refer to the “Min Ticks Fit” setting.

Fit: * Takes the implied volatility skew (Electronic or Settles) and completely overwrites your existing skew. * This will remove all previously configured strike volatilities and replace them with the implied skew.

Adapt: * Uses the implied volatility skew (Electronic or Settles) to adjust existing strike volatilities. * It only adjusts the volatility at each previously configured strike price to match the implied volatility skew. * It will not replace, remove, or add any strike volatilities that were not already configured.
