Ok Enrico,
I understand we're talking of different releases.
Which is the release you're currently using?
I've just checked the lastest available on quantlib.org, if you're using it, it's correct that you see: fixedcouponbond.cpp instead of fixedratebond.cpp (this is a new version of fixedcouponbond.cpp that hasn't been released yet).
So talking of fixedcouponbond.cpp, if I remember correctly, you don't have to pass a schedule but in the case of BTPS 3 06/01/07 you should pass the following:
FaceAmount: 100
issueDate: Tue, 01-Jun-2004
datedDate: Tue, 01-Jun-2004 (this is important is the first accrual date)
maturityDate: Fri, 01-Jun-2007
settlementDays: 3
coupons: 3%
couponFrequency: SemiAnnual
calendar: TARGET
dayCounter: Actual/Actual (ISMA)
accrualConvention: Unadjusted
paymentConvention: Following
redemption: 100
discountCurve: handle to the yield curve you're using to valuate the bond
stub: #N/A
backward generation: TRUE
The parameters above will give you the bond object you want to construct.....
Hope this will help.
Chiara

Hi Enrico
In QuantLib you don't need to set any issue price to create a bond object.
In general, there's no need to specify the issue price of a bond unless in
the bond's prospectus it is stated that the bond's yield is floored to a
minimum yield which is set depending on the issue price.
In your case, since the bond you mentioned is BTPS 3 06/01/07, which is a
vanilla fixed rate bond, you just need to construct a schedule given the
following static bond data:
Interest Accrual Date: Tue, 01-Jun-2004
Maturity Date: Fri, 01-Jun-2007
Tenor: 6M
Calendar: Target
AccrualBDC: Unadjusted
Termination Adjustment: Unadjusted
Backward Generation: TRUE
EOM: FALSE
First Date: #N/A
Next to Last Date: #N/A
and to pass all the other require input data which are:
settlementDays: 3
paymentBDC: "Following" (is not specified in the bond prospectus I read)
FaceAmount: 100
Schedule: see above
Coupons: 3%
dayCounter: Actual/Actual (ISMA)
Redemption: 100
issueDate: If omitted, default = bond schedule first date
YieldCurve: discounting yield term structure
You construct a fixedratebond object as illustrated above and price
correctly the bond in assetswap (I've checked my result against BBG's ASW
<go>).
Chiara
Ps please let me know if you have a more detailed prospectus of the bond
which gives you more information on its static data.
First of all many thanks for your reply.
I don't understand some things: first of all I cannot find a fixedratebond
class in the quantlib library. I tried using fixedcouponbond, but I don't
know how to pass it the scheduler object. I've seen in the source code
fixedcouponbond.cpp that is created a schedule passing it some parameters
from the constructor.
Sorry for my elementary questions, but I'm a beginner user of Quantlib.
Thanks
Enrico
