Yes I think Bob made a mistake there. However, the lines that SK posted are not my lines.
I haven't even really read that much on auction theory. I know the principals of it.
Basically, using the 70% value area, SK's lines show +/- 1 standard deviation away
from the POC.
My buyers/sellers auction zones are based on my own theories of supply/demand
when price is at my proprietary levels. I have never read anything of the sort anywhere and
if you have please show me as I would be interested in what others have discovered
or came up with on their own.
