What is the best strategy to bktest a pairs trade?

Start with Pairs Trading, or translating some of the V4 scripts below with WealthScript Translator:

ChartScript Family - Trade Like a Hedge Fund
ChartScript Family - Pairs Trading

regarding the Pairs Trading strategy referred to in the above link, how can I alter the code to hard code MULTIPLE different pairs. This would allow me to simply click on s symbol in a watchlist and see the results instead of constantly changing the hard-coded pairs each time. For example, in WL4 I used ascript that had a set up like the following:

CODE:

I assume in WL.Net I need to do something like the following:

CODE:

But I am having difficulties altering the Pairs Trading code to accomodate for the mutiple pre-set pairs. Any help will be appreciated.

What sort of trouble do you have?
