Pascal,

one last question: in your book, pages 128 and 129 you suggest to take to rate of change from the large effective volume serie.

In the VIT forum archive

http://www.effectivevolume.com/showt...&highlight=NEV

I found you states that

LER is the difference
between large positive EV and large negative EV (divided by the total
volume).

So my question is: should I first create a serie from the difference of positive and negative LEV than compute the rate of change or you simply take the rate of change from the LEV serie?

Thanks
