Reload to refresh your session. form, without using a solver routine The two curves must be generated simultaneously. You can retrieve the set of underlying dates and the corresponding rates by calling crv. ) and then infer the discount factors, this would not require a minimization technique as far as I understand. Two functions in the curves package are the core of the curve building calculations; bootstrap_contracts and max_smooth_interp. If you actually want to use vanilla swaps, you need to use SwapRateHelper, not OISRateHelper. For this example, the input market data is hard-coded and specified as 2 cell arrays of data, one which indicates the type of instrument and a second cell array containing the Settle, Maturity, and Market Quote for The basic idea of bootstrapping using QuantLib is to use the deposit rates and bond rates to create individual helpers. # global data. 31% and the 5-years rate is 35.
