Once you have saved a Yield Curve for a particular trade date and currency (for more information on saving rates see Saving a Yield Curve) at any stage you can then upload it back into the Yield Curve page for use in the current session.
It is important to note that loading an existing yield curve into the page will automatically overwrite the data currently displayed in it. However, SDX Interest Rates will not use the uploaded yield curve in any calculations until you tell it to do that by clicking the Accept button.
In addition, the uploaded rates will only be used for calculations that have the same trade date. So for example, if you upload a saved GBP 3m yield curve for 1 September 2009, even after you click the Accept button it will only be used in the pricing page for a GBP instrument based on the 3m index that also has a 1 September 2009 trade date.
To open a previously saved yield curve:
| 1. | In the Yield Curve page click Open. The SD-IR Explorer window opens in the Yield Curve folder. |
| 2. | Click the relevant currency folder. The yield curves saved for this currency are displayed on the right-hand side of the window. |
| 3. | To open the file you can do either of the following: |
Click the relevant file so it is highlighted and any comments appear in the middle panel. Then click the Open button.
Double-click the relevant file.
The rates in the selected file are uploaded to the Yield Curve page.
| 4. | To instruct the system to use the rates, click the Accept button. |
