<p>> Lionel, in addition to the points you make there was a serious flaw
in the
<br>> way Granville determined OBV. He applied all of the daily volume
either to
<br>> the up-volume or down-volume depending on whether the stock closed
up or
<br>down
<br>> for the day. Thus a stock closing up 1/8 point on one million shares
would
<br>> have the same increase in OBV as a stock moving up 2 points on one
million
<br>> shares. I read an article in the early '70's that calculated the
up-volume
<br>> as: ((High - Open) + (Close - Low))/2(High - Low). The reverse for
<br>> down-volume. This gives a much more accurate evaluation of
<br>> accumulation/distribution.
<br>>
<br>> The first edition of Perry's book was published in 1978. Based on
its
<br>> success, Perry was asked by Conti Commodity in St. Louis to manage
a
<br>> commodity account ($10,000 minimum to join). It did not do well in
the
<br>1980
<br>> swing and was closed some time later. Which just goes to show that
just
<br>> because you can write a good cookbook doesn't necessarily mean you're
a
<br>good
<br>> cook.
