Here is a link to a demo on my intermarket divergence tool, free from UsingEasyLanguage.com. System Trading Success published an article I did on intermarket analysis and Jeff did a intra-day demo for it.
Intermarket Divergence is a very powerful concept which I have been using since the mid 1990's when I invented it. In addition I written about it and shared systems which were developed using it since 1997. Many of the relationships I developed back then still work today.
