Hello Peter,

That's done. I have extended the class. I'm now going to add a OvernightBasisSwapRateHelper class so as to build my rates based on several basis swap quotes.

Best,

Pierre

Hi,
the FloatFloatSwap should be functional and would hopefully behave like the general swap set up with two floating legs. However it does not allow for on overnight index on its legs. Which could be added easily though. Same with the implied spread. Maybe it would be nicer to extend the existing class rather than set up a new one ?
Best regards
Peter
