1330: observationShift (SetInAdvance, Standard, FixingDate)

September 4, 2023



Have not tried


5.11 Trial Recommendation (Build 5)





Good day !

I have a question regarding the observationShift section, in particular the observationPeriodDates element.

The element contains three options: SetInAdvance, Standard, FixingDate. Everything seems clear with the SetInAdvance value, but there are questions about the other two.


1) Can you explain with an example what "Standard" actually means? Am I correct in my understanding that this is an ordinary observation shift, which may involve the use of a certain number of shift days + take into account rates and their weight from the observation period?

2) Regarding FixingDate, do I understand correctly that this option is used mostly for OIS swaps that have a reset other than 1D, and are based on term-rate 1M, 3M, 6M, etc.? Please explain how this method works too?


Thank you.

Best regards, Maksym

    The rules on each one are detailed in the ISDA documentation referenced by the schema,
    or take the FpML training courses.

    Users will need to buy documentation or training course.
