Stock as function of custom index?

[Jeff711]

Hello. I'm trying to look at a stock as a function of a custom index. For example, I would like to look at F / ( GM + IBM). The adv chart operators won't let me order the calculations so i get f/gm + ibm. Would anyone know a way to do this in an efs routine? Thanks for any help.

Here's how I would do it...

function main() {

return close("F") / (close("GM") + close ("IBM"));

}
