Here
is the code that I decided to use:
<FONT face=Arial color=#0000ff
size=2>
InList
= IIf(Year() == 1993, InWatchList(21), IIf(Year() == 1994,
InWatchList(21), IIf(Year() == 1995,
InWatchList(21), IIf(Year() == 1996,
InWatchList(22), IIf(Year() == 1997,
InWatchList(23), IIf(Year() == 1998,
InWatchList(24), IIf(Year() == 1999,
InWatchList(25), IIf(Year() == 2000,
InWatchList(26), IIf(Year() == 2001,
InWatchList(27), IIf(Year() == 2002,
InWatchList(28), IIf(Year() == 2003,
InWatchList(29), IIf(Year() == 2004,
InWatchList(30),False))))))))))));
Buy =
myFilterOK and myTimingOK and mySignalOK and InList;

<FONT face=Arial color=#0000ff

<FONT face=Arial color=#0000ff

<FONT face=Arial color=#0000ff
size=2>1. I like to test back to 1993 and I only had watchlists going back
to 1995. So, I took the liberty of stretching the 1995 list back to
1993. It isn't 100% accurate, but it is about 200% more accurate
than using a current list in 1993.
<FONT face=Arial color=#0000ff
size=2>
<FONT face=Arial color=#0000ff
size=2>2. If you are going to use de-listed stocks, you have to remember
to exit trades prior to running out of data for those stocks. I put
a specific value in the OI field on the 2nd from last day of trading to tell me
to close the position on the last day (if I happen to be in a trade
then).
<FONT face=Arial color=#0000ff
size=2>
<FONT face=Arial color=#0000ff
size=2>3. So that I don't have to juggle watchlists next week, I set up a
(current) watchlist for 2004 and included the code for it even though it won't
be taking effect yet.
<FONT face=Arial color=#0000ff
size=2>
<FONT face=Arial color=#0000ff
size=2>4. Yes, I know that I didn't have to cater specifically for the
last year (2004). However, I prefer to do things this way for
documentation purposes.
