Modifying Your Skew in View Mode

The editing capabilities available to you in a volatility skew window are available to you in view mode. The miniature volatility skew window is governed by the Vlty Skew menu.

Notice that the fields that comprise the skew definition are darkened. This indicates that they are not accessible at this level.

The fields that are accessible (skew calculation fields) enable you to re-calculate the skew curve and perform what-if calculations by shifting the skew curve. For information on changing the fields that govern the skew calculation.

You can also what-if volatility changes by adjusting the base volatility, which shifts the entire skew curve. To accomplish this, click on the cyan arrows in the lower left corner of the menu (see, above). Clicking on the up arrow causes the skew curve to move up the Y axis, showing what happens if the volatility increases. Similarly, clicking on the right arrow causes the skew curve to move right on the X axis. Clicking on the arrow keys causes the shift amounts to change and appear in cyan. Cyan values are locked. To restore the curve to an un-shifted state (default), click on the cyan value with the left mouse key. This causes the curve to return to its default position and changes the shift values back to zero.

Note that the skew name is rendered in white. This means that the skew has not been modified. If you modify this skew, its color in the Volatility Skews menu will change from white to green, indicating that the skew has been modified but not saved.
