Term Structures - Initialize from vector of quotes and dates

[Lucas Ingles]

Hello,

I am trying to use the Term Structure objects from QuantLib in my application.

My situation is: I already have all the points of the curve calculated by another system. In fact, I have a vector of dates and rates with 15000 points already interpolated (in actual days). What I need is a constructor similar to the ones of the class "YieldTermStructure", that takes a vector of Quotes and Dates, but I cant use "YieldTermStructure" direct because the class is abstract. I tried with the other derived term structure classes but with no success. Please, is there any object that suits my needs?

Here is a hipotetical example of my curve:

Date                  Actual Days     Rate

17/Aug/2015                      0       10.0%
18/Aug/2015                      1       10.1%

19/Aug/2015                      2       10.2%
20/Aug/2015                      3       10.3%
21/Aug/2015                      4       10.4%
22/Aug/2015                      5       10.5%
     .                                   .          .
     .                                   .          .
     .                                   .          .
22/Aug/2050               12789       14.5%
23/Aug/2050               12790       14.6%

Thank you very much,

Hi Lucas,

 

Depending on what the rate really means, you should use InterpolatedZeroCurve or InterpolatedForwardCurve instead.

Cheng

Cheng Li, thanks for your response.
I will try with that ones. What I dont understand about these objects is why they have 2 vectors of dates and 2 vectors of rates (the Rates/Forwards and Quote vectors). My rates are zero coupon rates from Brasil DI Futures market (they are not forward rates). I will try with the simpler constructors (the one with just the "yields" vector of Rates from InterpolatedZeroCurve).

Thank you again,
Lucas

Hi Lucas,

 

Another vector is for rates jump which you can omit it safely.
