Functions

calcDcf

: DayCountConventionEnum -> Date -> Date -> Decimal

Calculates the day count fraction given the correponding convention. Currently 30E360 is not supported as we do not want to expose the maturity date of the product as an additional parameter.

calcPeriodDcf

: DayCountConventionEnum -> SchedulePeriod -> Bool -> Date -> Frequency -> Decimal

Calculate day count fraction for a schedule period. It takes the following parameters:

  • DayCountConventionEnum: to specify which day count convention should be used
  • SchedulePeriod: the schedule period for which the day count fraction should be calculated
  • Bool: Whether day count fraction should be calculated on adjusted dates (if False: unadjusted dates)
  • Date: The maturity date of the instrument
  • Frequency: the frequency of the schedule period
