You can do many different things using a loop combined with stocknumbers.
Here is a simple example, it does nothing. The Explorer is nice in that it
accumulate columns, meaning if you loop three time you can have data output
in consecutive columns for each pass.
best regards,
Herman.
Buy=Sell=Short=Cover=0;
Filter = BarIndex() > BarCount-11;
WL=0;
List = GetCategorySymbols( categoryWatchlist, WL);
for( n=0; (Ticker=StrExtract( List, n))!= ""; n++); NumTickers=n-1;
for(Task=0;Task<=3;Task++)
{
AddColumn(Task,"Task",1.0,1,0);
if(Task==0)
{
// do pre-processing here
Test0 = Task; // dummy code
AddColumn(Test0,"Test0",1.0,1,colorBrightGreen);
}
else if(Task==1)
{
// Process normal code here
Test1 = Task; // dummy code
AddColumn(Test1,"Test1",1.0,1,colorLightBlue);
}
else if(Task==2)
{
// do post-processing here
Test2 = Task; // dummy code
AddColumn(Test2,"Test2",1.0,1,colorRed);
}
else if(Task==3 AND Status("StockNum")==NumTickers)
{
// Do something during the last ticker in the WL
AddColumn(Status("StockNum"),"StkNum",1.0,1,colorGreen);
}
}

Sorry I wasn't clearer. I know code doesn't run for stocks outside the test.
But if you had access to the total universe of stocks in the test, you could
calculate any stats you wanted on that population before processing began
(Status("StockNum") == 0), and use that info to score individual stocks. For
example, you could calculate their average price beforehand, and filter out
or downgrade individual stocks below that. You could also count the number
of stocks being processed, and so on. Top N anythings on the stocks being
processed are possible too I think, without requiring that proicessing run
on a watchlist, one whose number I know.
Make sense?
