CoupDays(Settlement: DateTime; Maturity: DateTime; Frequency: Integer; [Basis: Integer = 0]): Double;
CoupDays(Settlement: System.DateTime; Maturity: System.DateTime; Frequency: integer; Basis: integer): double;
Settlement. The payment day on securities. Must be less than Maturity
Maturity. The security's maturity date. Must be greater than Settlement
Frequency. The annual number of coupon payments. The parameter can take the following values:
1. Annual payments.
2. Semi-annual payments.
4. Quarterly payments.
Basis. The day calculation method used. Select a value from 0 to 4:
0. The day calculation method - American/360 days (NSAD method).
1. The day calculation method - Actual/actual.
2. The day calculation method - Actual/360 days.
3. The day calculation method - Actual/365 days.
4. The day calculation method - European 30/360 days.
The CoupDays method returns the number of days in the period of a coupon, which includes the settlement date.
To get the number of days from the coupon action start to the agreement date, use the IFinance.CoupDayBs function.
Add a link to the MathFin system assembly.
Sub UserProc;
Var
r: Double;
Begin
r := Finance.CoupDays(DateTime.ComposeDay(2008,01,01), DateTime.ComposeDay(2008,06,01), 4, 0);
Debug.WriteLine(r);
End Sub UserProc;
Imports Prognoz.Platform.Interop.MathFin;
…
Public Shared Sub Main(Params: StartParams);
Var
r: double;
Finance: FinanceClass = New FinanceClass();
DateTime1, DateTime2: System.DateTime;
Begin
DateTime1 := New DateTime(2008,01,01);
DateTime2 := New DateTime(2008,06,01);
r := Finance.CoupDays(DateTime1, DateTime2, 4, 0);
System.Diagnostics.Debug.WriteLine(r);
End Sub;
After executing the example the console window displays the number of days in the coupon period that is equal to 90.
