When to exclude payment from SWAP valuation

[Andre Louw-2]

Hi,

Just a quick question.

Looking at the swap module I see QuantLib excludes cashflows from the NPV of a Swap according to the termstructure's settlementDate. Depending on how you look at it, could this not alternatively be todaysDate? Could we maybe add a ifdef to give the flexibility for both? Is there a specific market convention applicable to this?

The main problem right now is that the term structure does not  
extrapolate backwards to today's date.

I don't know. Anybody?

In the meantime, you can create your term structure with referenceDate  
= todaysDate and capitalize 2 days...
