Overnight Indexed Swap (OIS) vs. SARON

[RogKle]

The valuation of Switzerland's OIS vs. SARON has to consider a "Pay Lag". This means that a payment happens not on the "Accrual End Date" but - in case of Switzerland - two business days later. Therefore a "Pay Lag" should be implemented in the schedule for the fixed and floating leg and in the qlOISRateHelper. It seems that the original OISRateHelper class does already provide a parameter to enter the payment lag, at least in the latest release, but it can't be used form qlOISRateHelper in Excel.

I'm sorry, but I'm still waiting for an answer to my comment.

this would require a volunteer to implement the change and contribute it. you might try the quantlib-users mailing list:

I was doing some other QL addin work so picked this up -- see https://github.com/eehlers/QuantLibAddin-Old/pull/5#

many thanks as well! What about the function qlSchedule to value a running OIS by using qlOvernightIndexedSwap?
