I’m a relative novice to technical investing, and having read a few articles on the subject, it would seem that one of the best leading indicators would appear to be on balance volume. However, although most of the (free) technical analysis sites I’ve come across show the OBV graph, they do not appear to hold the OBV data upon which the graph is based.


Does anyone know if there are any sites out there – free or otherwise – which has easily accessible OBV data for any given share?


Otherwise – I might have to try converting the graphs to data somehow – again, can anyone recommend any conversion tools for this?


Generally speaking, do people agree that OBV is one of the best leading indicators? If not, does anyone have views as to any leading indicators they consider to be more reliable than OBV?


Many thanks in anticipation.

I'm enclosing a photo. I just finished reading a study published a while back. The author took 7 common volume indicators and tested them all. He found the OBV to be the worst of the 7. Here is how to read the photo:

I had a list of many volume indicators that I wanted to research. On the photo, I moved the 7 in the study to the top of the page. In the study, the top 3 were judged the best by far. The next 2 in the middle had performed better than the 2 below them and worse than the two above them. In other words, the top 7 in the photo were the in-order finishers in this study. All indicators below the 7 just were not in the study.

Now I know to use only the top 3. Or if I am on a web site that offers a few indicators, I'll look for the one that is highest on the list.
