I came across the following chart on a blog (it was Teresa Lo's site). I've been trying to do this in Investor RT for a few weeks now and can only get it to a ratio chart with my primary frame of reference as a line chart.

I really like how it appears that Tradestation can reference the benchmark as a zero line, but I can't seem to fins anyplace else that references the "rebase" on the chart. Is that merely what the author has named the function, and if so what is the function I would be able to research in Tradestation to learn more about this.

Also, if anyone knows IRT and can point out how I would be able to accomplish this on that platform I would also be grateful.

Thanks
