expires {FinancialInstrument} | R Documentation |
extract the correct expires value from an instrument
Description
Currently, there are methods for instrument
, spread
,
character
, and xts
Usage
expires(x, ...)
Arguments
x |
instrument or name of instrument |
... |
arguments to be passed to methods |
Details
Will return either the last expiration date before a given Date
, or
the first expiration date after a given Date
(if expired==FALSE
).
If an instrument
contains a value for expires that does not
include a day (e.g. "2012-03"), or if the expires value is estimated from
a future_series
primary_id, it will be assumed that the
instrument
expires on the first of the month (i.e. if the expires
value of an instrument were "2012-03", or if there were no expires value
but the suffix_id were "H12", the value returned would be "2012-03-01").
Note that most non-energy future_series expire after the first of the month
indicated by their suffix_id and most energy products expire in the month
prior to their suffix_id month.
