Note also, that if you *really* just want to work on a single pair at
a time. The same construction can be used, except that each pair of
lists contains a single item.
e.g.
watchList0 = A
watchList1 = X
watchList2 = M
watchList3 = Y
watchList4 = I
watchList5 = Z
Then change the line:
list = CategoryGetSymbols(categoryWatchlist, 2);
to:
list = CategoryGetSymbols(categoryWatchlist, Param("Opposite", 1, 1,
63));
That way you can select the watchlist to act upon, then use the
Parameters dialog to select the opposite list before running.
