What's wrong with the "both symbols in a single list" approach? I
believe that the assumption is that you would have multiple lists,
each with exactly two symbols (as you had originally suggested). Where
are you running into problems?
If it's a case of the script logic not being applicable from one pair
to the next, then the whole hard coding of names problem goes away
because each script would be customized to a pair and you could hard
code the names after all, as per Tomasz's example. Otherwise, were you
not able to dig out the names correctly using StrExtract?

work because its alphabetizing each list. So when I enter the orders
for the first list its fine, but then I get to the second list and it
alphabetizes that so it ruins the order with the first list. This is
tough man!
