By default, the OIS Curve page opens with the OIS curve for the current currency (if this currency is supported for the overnight index swap; otherwise it displays USD), the current trade date and the market data cut-off time set in the pricing page from which it was opened. In addition, the swap rate tenors come from the customize settings for the OIS curve (for more information see Customizing the OIS Curves).
Once the page is open you can then control what data is displayed in the page and how as follows:
You can control for which trade date the OIS curve is displayed.
By default this is taken from the pricing page from which this page was opened, but you can change it using the Trade Date field.
You can control for which currency the OIS curve is displayed.
By default this is taken from the pricing page from which this page was opened if this currency is supported for the inflation instrument; otherwise it displays USD. But you can change it using the Currency dropdown list.
For which market data cut-off time the OIS curve is displayed.
By default this is taken from the pricing page from which this page was opened, but you can change it using the Cut Off dropdown list. For more information on this feature see Changing the Market Data Cut-off Time.
You can control the swap rate tenors which are displayed.
