[R-SIG-Finance] Forward Curve Fitting

[Oleg Mubarakshin]

Hi Team,

Maybe someone can help me with the below.

What would be the best way to fit the BTC/USD forward curve?

It is quite agile (including its shape).

Please see attached example: Deribit's market data, including futures and
options (from put-call parity), 24 cutoffs, one per hour, the most recent
(blue line) goes with bid/ask-s. Mobility of the curve in this sample is
not so bad TBH (can be much worse).

The Nelson-Siegel and Svensson models didn't work for me (maybe I didn't
use them properly?).

I'm ready to give up and fit it with splines but maybe somebody knows a
better way?
