Thanks Tom for the lesson on stockcharts.com stuff, most useful.
As to the date range for the slider I wasn't all that interested in an exact range but rather a setting that helped visualize what has gone on in terms of market cycles and which sectors are in/out of favor.
I found it quite useful, especially that the metrics being used really affect the way things are perceived. Of course, we've known that a long time otherwise we wouldn't have the old saw about there being liars, damn liars, and statisticians.
Best,
Allen
