Detailed Description

Base bond class.

Derived classes must fill the uninitialized data members.

Warning

Most methods assume that the cash flows are stored sorted by date, the redemption(s) being after any cash flow at the same date. In particular, if there's one single redemption, it must be the last cash flow,

Tests

*

price/yield calculations are cross-checked for consistency.

*

price/yield calculations are checked against known good values.

Examples:

FittedBondCurve.cpp.

Constructor & Destructor Documentation

Bond (Natural settlementDays, const Calendar & calendar, const Date & issueDate = Date(), const Leg & coupons = Leg())

constructor for amortizing or non-amortizing bonds. Redemptions and maturity are calculated from the coupon data, if available. Therefore, redemptions must not be included in the passed cash flows.

Bond (Natural settlementDays, const Calendar & calendar, Real faceAmount, const Date & maturityDate, const Date & issueDate = Date(), const Leg & cashflows = Leg())

old constructor for non amortizing bonds. Warning

The last passed cash flow must be the bond redemption. No other cash flow can have a date later than the redemption date.

Member Function Documentation

const Leg & cashflows () constNote:

returns all the cashflows, including the redemptions.

const Leg & redemptions () constreturns just the redemption flows (not interest payments)

const boost::shared_ptr<CashFlow>& redemption () constreturns the redemption, if only one is defined

Real cleanPrice () const

theoretical clean price The default bond settlement is used for calculation.

Warning

the theoretical price calculated from a flat term structure might differ slightly from the price calculated from the corresponding yield by means of the other overload of this function. If the price from a constant yield is desired, it is advisable to use such other overload.

Real dirtyPrice () const

theoretical dirty price The default bond settlement is used for calculation.

Warning

the theoretical price calculated from a flat term structure might differ slightly from the price calculated from the corresponding yield by means of the other overload of this function. If the price from a constant yield is desired, it is advisable to use such other overload.

Real settlementValue () const

theoretical settlement value The default bond settlement date is used for calculation.

Rate yield (const DayCounter & dc, Compounding comp, Frequency freq, Real accuracy = 1.0e-8, Size maxEvaluations = 100) const

theoretical bond yield The default bond settlement and theoretical price are used for calculation.

Real cleanPrice (Rate yield, const DayCounter & dc, Compounding comp, Frequency freq, Date settlementDate = Date()) const

clean price given a yield and settlement date The default bond settlement is used if no date is given.

Real dirtyPrice (Rate yield, const DayCounter & dc, Compounding comp, Frequency freq, Date settlementDate = Date()) const

dirty price given a yield and settlement date The default bond settlement is used if no date is given.

Real settlementValue (Real cleanPrice) const

settlement value as a function of the clean price The default bond settlement date is used for calculation.

Rate yield (Real cleanPrice, const DayCounter & dc, Compounding comp, Frequency freq, Date settlementDate = Date(), Real accuracy = 1.0e-8, Size maxEvaluations = 100) const

yield given a (clean) price and settlement date The default bond settlement is used if no date is given.

virtual Real accruedAmount (Date d = Date()) const [virtual]

accrued amount at a given date The default bond settlement is used if no date is given.

virtual Rate nextCouponRate (Date d = Date()) const [virtual]Expected next coupon: depending on (the bond and) the given date the coupon can be historic, deterministic or expected in a stochastic sense. When the bond settlement date is used the coupon is the already-fixed not-yet-paid one.

The current bond settlement is used if no date is given.

Rate previousCouponRate (Date d = Date()) const

Previous coupon already paid at a given date. Expected previous coupon: depending on (the bond and) the given date the coupon can be historic, deterministic or expected in a stochastic sense. When the bond settlement date is used the coupon is the last paid one.

The current bond settlement is used if no date is given.

void setupExpired () const [protected, virtual]This method must leave the instrument in a consistent state when the expiration condition is met.

Reimplemented from Instrument.

void setupArguments (PricingEngine::arguments *) const [protected, virtual]When a derived argument structure is defined for an instrument, this method should be overridden to fill it. This is mandatory in case a pricing engine is used.

Reimplemented from Instrument.

Reimplemented in CallableBond, and CallableFixedRateBond.

void fetchResults (const PricingEngine::results * r) const [protected, virtual]When a derived result structure is defined for an instrument, this method should be overridden to read from it. This is mandatory in case a pricing engine is used.

Reimplemented from Instrument.

void addRedemptionsToCashflows (const std::vector< Real > & redemptions = std::vector< Real >()) [protected]This method can be called by derived classes in order to build redemption payments from the existing cash flows. It must be called after setting up the cashflows_ vector and will fill the notionalSchedule_, notionals_, and redemptions_ data members.

If given, the elements of the redemptions vector will multiply the amount of the redemption cash flow. The elements will be taken in base 100, i.e., a redemption equal to 100 does not modify the amount.

Precondition:

The cashflows_ vector must contain at least one coupon and must be sorted by date.

void setSingleRedemption (Real notional, Real redemption, const Date & date) [protected]This method can be called by derived classes in order to build a bond with a single redemption payment. It will fill the notionalSchedule_, notionals_, and redemptions_ data members.

void setSingleRedemption (Real notional, const boost::shared_ptr< CashFlow > & redemption) [protected]This method can be called by derived classes in order to build a bond with a single redemption payment. It will fill the notionalSchedule_, notionals_, and redemptions_ data members.

void calculateNotionalsFromCashflows () [protected]used internally to collect notional information from the coupons. It should not be called by derived classes.
