Does anyone use the advance/decline (AD) line? I'm reading chapter 8 but the indicators, apart from stage analysis, seem very specific to the NY markets? I'd appreciate any feedback/insights. Many thanks!

I use advance / decline data. There are a few charts on line and some of the charting providers might carry it. However, I suspect the US data is commonest. You can get US date from:

For some other data I calculate it myself. Which takes much more effort and has some large limitations.

Thanks for the link. The data looks like it does in the book! It serves to remind me just how old the book is now. I suppose that when Stan's organisation was maintaining this data, it was for all of his PTR subscribers. It must be a very arduous task for a single individual to maintain.
