RE: [amibroker] How to use multiple NASDAQ lists?

["William Peters" <williampeters@xxxxxxxxxxxx>]

Hello Chuck,
 
Some ideas... 
(untested)
 
Set the AA 
range From/To date to the total period 1997 - 2003 or whatever period you 
are testing.
<FONT 
size=2> 
Put all the symbols from all the files into 
a single watchlist called, say "ALLN100Symbols"
and set the Apply to filter in AA to 
that watchlist. (This will save you from having to scan the whole 
database)
 
Add each years list into thier own 
watchlist i.e 47 = 1997  48 = 1998 etc etc.
 
Within your code write an If/Else If 
statement like this:
 
If ( Year() == 1997 )
Cond1 = InWatchlist(47);
else if ( Year() == 1998 )

Cond1 = InWatchlist(48);
 
etc etc..
 
add that condition (Cond1) to your buy 
or short statement and that should be pretty close..and thanks for the 
lists.

How to use multiple NASDAQ lists?
I'm 
hoping that one of you guys (or gals) who were able to use the historical NASDAQ 
lists that I posted can now help me.   I basically want to trade only 
the stocks on the 1997 list, for instance, in 1997.   The stocks on 
the 2001 list in 2001.   And so on.
<FONT face=Arial color=#0000ff

I'm 
assuming that I would make a watchlist that contains the sum of all of the 
watchlists (1995 to 2003).   I would then create a separate watchlist 
for each year.   Then, while trading the master list, my AFL would 
check the year using the Year() function and only trade if the stock was in the 
watchlist for the corresponding year.   Once in a trade, I won't worry 
about exiting if the stock no longer appears in the list.   I have my 
own way of determining if the stock is no longer traded.

Anyone 
care to help me and, no doubt, others by supplying some 
code?
