Building scenarios
The scenario builder option allows participant users to add, delete and edit mock-up Bank Guarantees. The associated graphs and numerical data are updated in real time. The aim of the page is to assist participants in planning and managing Bank Guarantees at the present time and in the future.
The mock-up Guarantees are not saved into the Market Management System and therefore will not be counted as current/active Bank Guarantees in the Status Page. Information will be discarded when the page is closed.

To add a bank guarantee:
- In the Current Active Credit Support section, click Add Guarantee.
The Add Bank Gurantee (Simulated) window opens.
- Select a date range by spanning over the date Commencement and Expiry dates.
- Next, add a Guarantee Amount.
- Click Create.
