My thinking around how it could be useful is on an individual stock basis, as you could have a screener that would identify when a stock became greater than an 8. As that would give you much fewer, but higher quality stocks to look at visually to do a more thorough analysis, and also show you which sub sectors had multiple stocks with strong ratings, and highlight when multiple stocks in a sector moved up the scale into the strong range.

The rating of individual stocks could also be used as breadth indicator like you've done for the index, as you would have a scale of 0-10. So would work in the same way as the Bullish Percent Index using the P&F plot of it to give signals.

General repose to these postings, not particularly ISA...

I can see it working for breadth, but if you want to catching individual stocks breaking into stage 2 then you need to spot stocks exceeding the boundary of the previous day's channel, i.e. a Donchian channel.  If you look at that and above average volume you will capture the breakout points.  Just looking that various MA's means that if you sort for the most positive stocks you will end up sorting for the most overextended stocks or ones where it is too late for a good entry.
