ForwardSpreadedTermStructure¶
- class ForwardSpreadedTermStructure(HandleYieldTermStructure yts, Quote spread)¶
Bases:
YieldTermStructureTerm structure with an added spread on the instantaneous forward rate.
This term structure remains linked to the original structure; any changes in the latter will be reflected in this structure.
- Parameters:
- yts
HandleYieldTermStructure The handle to the original yield term structure.
- spread
Quote The spread to be added to the forward rate.
- yts
- Attributes:
calendarCalendar: calendarday_counterDayCounter: day counter- extrapolation
max_dateDate: the latest date for which the curve can return valuesmax_timeTime: the latest time for which the curve can return valuesreference_dateDate: the date at which discount = 1.0 and/or variance = 0.0settlement_daysint: number of settlement days used for reference date calculation
Methods
discount(self, value, bool extrapolate=False)forward_rate(self, d1, d2, ...)Returns the forward interest rate between two dates or times.
time_from_reference(self, Date dt)date/time conversion
zero_rate(self, d, ...)Returns the implied zero-yield rate for the given date.
