A named list containing two data.frames, one
for calls and one for puts. If more than one
expiration was requested, this two-element list
will be contained within list of length length(Exp)
.
Each element of this list will be named with the expiration
month, day, and year (for Yahoo sourced data).
If Exp
is set to NULL
, all expirations
will be returned. Not explicitly setting will only
return the front month.
