Need help creating new spread indicator

[Brian Gaddis <bngaddis@xxxxxxxxxxxxxx>]

Need some help with this one. I'm trying to construct a Will-Spread.
I want to trade treasury bonds using gold as a filter. Larry Williams
does this for the first part of his Will-Spread:

Divide the price of T-bonds by the price of gold, then multiply
by 100.


Any tips on how I can create a new Spread indicator in MetaStock
to do this?

Thanks.
