Re: [Quantlib-dev] Coupons with multiple resets

Hello Leopold,
    the multiple-reset feature is relatively recent and it's not available
in SwapRateHelper.  There is an open issue about this (
https://github.com/lballabio/QuantLib/issues/2138) so thanks for
posting—I'll point to this thread in that issue as further evidence.
You can follow the issue to check if there's any progress.

Best,
    Luigi
