Hi,
Sorry, it was not clear that you were wanting to act on both symbols.
I thought you were trying to buy from the first list only, based on
signals/confirmatio n from the second list.
As you've now discovered, the Foreign functionality allows access to
foreign data, but it does not allow you to generate signals for that
foreign symbol. To act on the symbol, it must appear in the watchlist
and be processed in turn.
Tomasz has answered your question, which is the route that you were
originally heading down. But, he did not address the hard coded names
that you were trying to avoid.
To avoid the hard coded names of Tomasz's answer, Dingo gave you the
answer, which is also what I used in my earlier sample. Specifically;
use StrExtract from the watchlist.
Putting it all togeather...
Again the symbols will be evaluated in alphabetical order, but
CategoryGetSymbols will give the ordering as they appear in the
watchlist (i.e. not necessarily alphabetized) . So, if it matters,
populate your list such that the symbol you want to to be treated as
first actually appears first in the watchlist, even though the second
may get run through the script before the first one.
Buy = Sell = Short = Cover = 0;
list = CategoryGetSymbols( categoryWatchlis t, 1);
first = StrExtract(list, 0);
opposite = StrExtract(list, 1);
_TRACE(first + " and " + opposite);
if (Name() == first) {
SetForeign(opposite );
// Read whatever you want from opposite data
RestorePriceArrays( );
Buy = ... enter long for first symbol
Sell = ... exit long for first symbol;
}
if (Name() == opposite) {
SetForeign(first) ;
// Read whatever you want from first data
RestorePriceArrays( );
Buy = ... enter long for opposite symbol
Sell = ... exit long for opposite symbol;
}

it on the first watchlist and then using the setforeign(opposite );
function. But Im having a problem. There are variables I declared
early in the code. Then I say setforeign(opposite ); Then put in buy
conditions based on those variables but I get no buys or sells in
this foreign ticker. Only buys and sells in the first watchlist. How
come?
