Re: [Quantlib-users] Eris SOFR Swap Futures

[ze73 m. <ze7...@ya...>]

 Thanks so much for shring your thoughts, Tom and Peter!

I mean to directly build the curve from the Eris futures market prices (available from IB for example) and from the instrument spec on the Eris web site. The data in their FTP server is indeed great for validation but we don't have a license for it. My understanding was also that we would need a new rate helper for OIS Swap Futures and I was wondering if anyone would kindly share any experience modeling swap futures in quantlib, please?

 Well, I meant to use their PV01. But their ftp data has everything you
need anyhow

Even daily discount factors which is arguably the safest way to
replicate their curve precisely

To directly build the curve from the futures prices and the PAI we
would need a new rate helper.
