[Quantlib-dev] help with amortizing notionals

[Jose Aparicio-N. <ja...@fr...>]

Hi all, I am failing to create an amortizing notional bond schedule and I am not
sure whether I am misinterpreting the way I have to pass the data or a REQUIRE
is written with the test condition in the reverse direction.

I create the bond:

    DayCounter dayCtr = ActualActual();

    Real bondFaceVal = 1000000.0;
    Real redemption  = 100.0;
    Date bondMaturity(todaysDate + Period(3, Years));

    Schedule scheFix(todaysDate,
                     bondMaturity,
                     Period(3,TimeUnit::Months),
                     TARGET(),
                     ModifiedFollowing,
                     ModifiedFollowing,
                     DateGeneration::Backward,
                     false);

    std::vector<Real> notionls(5, bondFaceVal);
    notionls.insert(notionls.end(), 4, bondFaceVal/10.);
    notionls.insert(notionls.end(), 4, bondFaceVal/100.);

    boost::shared_ptr<AmortizingFixedRateBond> amortFix(
      new AmortizingFixedRateBond(0,
        notionls, scheFix, std::vector<Rate>(1, 0.05),
        dayCtr, ModifiedFollowing,
        std::vector<Real>(1, 100.)));


I fail the REQUIRE (line 508 in bond.cpp) at the second notional insertion in

void Bond::calculateNotionalsFromCashflows()


When constructing the bond with a sinking freq I get the same test failure:

    boost::shared_ptr<AmortizingFixedRateBond> amortFix(
      new AmortizingFixedRateBond(0,
        TARGET(), bondFaceVal, todaysDate,
        Period(3, Months), Frequency::Monthly, 0.05,
        dayCtr, ModifiedFollowing, todaysDate));
