You could try using a loopp for this or combine inot one function like this
index=IIf( Year() == 2005 AND Month() == 6 AND Day()>=17 AND Day()<24,1, IIf( Year() == 2005 AND Month() == 6 AND Day()>=24,2,-1));
as an aside you could save yourself a lot of typing by using datenum()
eg
di = datenum();
index=IIf( di>=1050617 and di<1050624, 1, IIf( di>=1050624, 2, -1 ));

Hello. I want to do backtesting with a system that selects stocks from
a particular watchlist depending on the date, but I cannot get it to
work properly. Here's the pertinent part of my code:
index=IIf( Year() == 2005 AND Month() == 6 AND Day()>=17 AND
Day()<24,1,-1);
index=IIf( Year() == 2005 AND Month() == 6 AND Day()>=24,2,-1);
Buy = index > 0 and InWatchList(index);
So if the date is between 2005-6-17 and 2005-6-24, index should be 1,
otherwise -1. And if the date is on or after 2005-6-24, index should
be 2, otherwise -1.
The problem is that I get the error that the fucntion expects a
different argument type. The error goes away if I use LastValue for index:
Buy = index > 0 and InWatchList(LastValue(index));
However, the above seems to result in only stocks being selected from
Watchlist(2), and never Watchlist(1).
How do I correct this? Thanks in advance.
