   Also Known As:

   Vols = Volatility.
2. Disable Auto Update Base Skew's Futures Price: Disable the base futures price from being automatically updated when using any of the fit or adapts methods.
3. Float Rate: The volatility skew float rate. This describes the rate at which the skew moves relative to the futures movement.

Details:

0 = fixed
1 = 100% float
Max = 2(200%float)
Float rate can be set negative
4. Volatility Creation Method: click in the value area to choose the method for creating volatilities.

   Descriptions:

   Volatility per strike: Input a volatility on a per strike basis.
   Multiple slopes: Create multiple skews between multiple strikes.
   Standard deviation: Uses a DTE standard deviation skewing method. Input Volatility at standard deviation points.

   Comments:

   Volatility per strike: Select a fit method to build or rebuild the skew.
   Multiple slopes: Select an adapt method to rebuild the skew.
   Standard deviation: It is pro-rated based on the DTE. The adapt method can be used to build and manage the skew.

7. Max Curves: Set the maximum number of curves allowed. The mount of smoothing to be applied.

   Example:

   2 = max of 2 curves(applies a 3rd order polynomial)
   3 = max of 3 curves(applies a 4th order polynomial)
8. Strikes Volatilities:
9. Min Ticks: Set the number of ticks to ignore when using a fit method.
10. Change with Vol change: Change the minimum and maximum volatility when all volatilities are changed.
11. Max volatility: Set the minimum volatility for this month.
