Fit volatility value used for calculating theoretical call and put values. Fit vols are calculated by TT but can be modified by a user in the Vol Curve Manager widget.

Implied volatility value. Implied volatilities are calculated using the midpoint of bid and ask prices.

SV

Settlement volatility value, which indicates volatility calculated per strike using settlement prices.
