FloatingRateCoupon fixingDate() Following

[klin333]

Hi,

In FloatingRateCoupon fixingDate(), it hardcodes Preceding business day convention.

QuantLib/ql/cashflows/floatingratecoupon.cpp

Lines 79 to 84 in 1378d49

	Date FloatingRateCoupon::fixingDate() const {
	// if isInArrears_ fix at the end of period
	Date refDate = isInArrears_ ? accrualEndDate_ : accrualStartDate_;
	return index_->fixingCalendar().advance(refDate,
	-static_cast<Integer>(fixingDays_), Days, Preceding);
	}

What can be done if I want Following business day convention. An example is this Australian bank hybrid, where the coupon schedule is Unadjusted, ie coupon accrual start and end dates are 22nd of each quarter, Unadjusted (even though coupon payment itself is Following business day adjusted with no compensation to holder for the delay). I believe this means that the Schedule object must use Unadjusted. However, this hybrid bond also states that the index fixing "will be determined on the first Business Day of each Distribution Period", ie in the quoted lines above in fixingDate(), I need Following.

This feels like quite a large job, as it involves FloatingRateCoupon, FloatingLeg, IborCoupon, IborLeg, FloatingRateBond.

Hmm, you're right, it's tricky to add to the current implementation.
