FIX Data Type Tenor

Name	BaseType	First introduced	Deprecated
Tenor	Pattern	FIX.4.4

used to allow the expression of FX standard tenors in addition to the base valid enumerations defined for the field that uses this pattern data type. This pattern data type is defined as follows:

Dx = tenor expression for "days", e.g. "D5", where "x" is any integer > 0

Mx = tenor expression for "months", e.g. "M3", where "x" is any integer > 0

Wx = tenor expression for "weeks", e.g. "W13", where "x" is any integer > 0

Yx = tenor expression for "years", e.g. "Y1", where "x" is any integer > 0

Notes

7/Mar/2011, I was interested to know which tags uses the Tenor dataType. I had to grep it in the repository and found that Tenor is a 'UnionDataType' in tag 63. That is its only reference in the repository.
