Edit Mode

The parameters menus enable you to apply parameters at the system, or global, level, and at the quote window level. You can also change parameters at lower levels of Aspen Systems: at the underlying instrument level, and at the individual option level. To change parameters at these levels, you use Aspen Systems Edit Mode feature.

Before you can change option values in a quote window, the window must be in Edit Mode. To get into Edit Mode, select Edit Cells Off from the Quote Menu. (The menu selection serves as a reminder of the active quote windows current Edit Mode state.) This selection is a toggle. When you enter Edit Mode, the selection changes to Edit Cells On. To exit Edit Mode, select Edit Cells On. Edit Mode enables you to edit prices, volatilities, and other values passed to the options pricing model.

When you enter a quote windows Edit Mode, you can change the values you see in the quote window. There are two methods for changing a value:

1. Using the Edit Box

2. Using a Quote Code menu.

The method you use to edit a particular value depends on the quote code used to display the value in the layout. You edit some codes with an edit box, and you edit others with a menu.

When you edit a value, it becomes locked. A locked value remains as youve changed it until you unlock it. Lets look at editing and locking values in more detail.
