The Date Adjust Method
When you use date adjustment, Aspen Systems evaluates your options as though
you somehow reset the calendar to a different date and then caused time to stop.
The system continues to evaluate options based on the date you specify, and
the time to expiration remains static. Among other things, using the date
adjust method enables you to forecast options performance at expiration. The
following example shows you how to base time to expiration on a specific date. For
illustrative purposes, assume the current date is 3/3/96 and follow these steps:
1. Display the Quote Menu.
2. Select Option Parameters.
3. Toggle the Expire field.
Click on the Expire field.
Use the arrow keys to move the highlight to the Expire field and press
The value changes to Date.
4. Open the Adjust field.
Click on the Adjust field.
Press the right arrow key to move the highlight to the Adjust field and press
5. Type a date in MM/DD/YY format (Month/Day/Year), i.e., 3/3/96.
6. Press
7. Select Draw.
Notice that the XDAYS field for all options changed to 32, and a date appeared
below the XADJUST field. This is the date you specified, and it is displayed
using the DADJUST quote code. If the date adjustment is satisfactory, select Done or press
The Quote Option Parameters menu is displayed.
Normally, you will want to specify a date that is after the current date but
before the expiration of the option. However, Aspen Systems accepts any date
you specify. If you enter a date that is after expiration, Aspen Systems assumes
you want to see performance at expiration. If you enter last Friday
