I would like to do an exploration to calculate simple stock returns, but at fixed dates. I don't want to use the Ref function which links the return to today's date.
For example: % return from May/1/2002 to May/1/2003 % return from Feb/1/2004 to Feb/28/2005 How can I specify those dates in an exploration? I'm guessing I could use Datenum, but how would I ask for the closing price on datenum=1011231? Thanks, Steve
