overridevirtual |
returns whether the instrument might have value greater than zero.
Implements Instrument.
Definition at line 72 of file varianceswap.cpp.
Here is the call graph for this function:
◆ strike()
| Real strike | ( | ) | const |
Definition at line 120 of file varianceswap.hpp.
◆ position()
| Position::Type position | ( | ) | const |
Definition at line 128 of file varianceswap.hpp.
◆ startDate()
| Date startDate | ( | ) | const |
Definition at line 112 of file varianceswap.hpp.
◆ maturityDate()
| Date maturityDate | ( | ) | const |
Definition at line 116 of file varianceswap.hpp.
◆ notional()
| Real notional | ( | ) | const |
Definition at line 124 of file varianceswap.hpp.
◆ variance()
| Real variance | ( | ) | const |
◆ setupArguments()
|
overridevirtual |
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.
Definition at line 46 of file varianceswap.cpp.
◆ fetchResults()
|
overridevirtual |
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.
Definition at line 57 of file varianceswap.cpp.
Here is the call graph for this function:
◆ setupExpired()
|
overrideprotectedvirtual |
This method must leave the instrument in a consistent state when the expiration condition is met.
Reimplemented from Instrument.
