Just make any number of watchlists that you want, each with exactly
two symbols. Then, select whichever list you want to work against in
the AA window and run the following script. Select a different
watchlist in the AA window and run the script again. Repeat for as
many lists as you have.
There may be a cleaner way for getting the active watchlist. But the
method used should work.

Buy = Sell = 0;
ab = CreateObject( "Broker.Applicat ion");
aa = ab.Analysis;
wl = aa.Filter(0, "watchlist") ;
list = CategoryGetSymbols( categoryWatchlis t, wl);
ticker1 = StrExtract(list, 0);
ticker2 = StrExtract(list, 1);
_TRACE(CategoryGetN ame(categoryWatc hlist, wl) + ": " + ticker1 + "
and " + ticker2);
if (Name() == ticker1) {
SetForeign(ticker2) ;
// Read whatever you want from second data, e.g.
foreignClose = Close;
RestorePriceArrays( );
Buy = foreignClose > Close;
Sell = foreignClose < Close;
}
if (Name() == ticker2) {
SetForeign(ticker1) ;
// Read whatever you want from first data, e.g.
foreignHigh = High;
RestorePriceArrays( );
Buy = foreignHigh > High;
Sell = foreignHigh < High;
}
