window have a char limit, 99 stocks still works for me :-) Perhaps TJ
can provide a work around ... I cc'd this to him.

RE: [amibroker] Re: to HERMAN: N100 Correlation table
I
was extremely intrigued by your matrix, so I tried to run it against my N100
watchlist containing 100 tickers (of course).
<FONT face=Arial color=#0000ff
size=2>
It
crashes with an access violation. It will run a handful of
tickers with no problems, but sure doesn't like 100.
<FONT face=Arial color=#0000ff

Has
anyone else tried it with 100 tickers or more?

[amibroker] Re: to HERMAN: N100 Correlation
tableHerman,There is no need to write the
100 tickers. If they belong to WL10, thenlist =
GetCategorySymbols( categoryWatchlist, 10 );tickerlist="";for( i
= 0; ( sym = StrExtract( list, i ) ) != ""; i++
){tickerlist=tickerlist+sym+",";}Title=tickerlist;The
advantage is that you don't have to correct the code after any N100
change, it is done automatically as soon as you correct WL10.Note
also that StrExtract() needs a "comma-separated list of items",
that's why the above +",". The result will have a "," at the
end, but this is not a problem.Dimitris Tsokakis--- In
