Stig:
The rule of thumb that I have seen in various books is
that arithmetic is OK for periods less than one year (difference between the two
is small), but that semi-logarithmic should be used above that (or just use
semi-log all the time). I don't know why one would use semi-log for
extended price ranges unless the time factor comes into play. As for which
trendline is right, I don't know of any study that has established which gives
the best signals, and that should be the determining factor. Perhaps
someone has more information.

The picture is a bit different if semi-logarithmic
scale is used, which is appropriate for extended
times.

Interesting point Bill, I have to think about
that one.
Do you mean to say that one is right and one is
wrong?
Or could one say: "Hey, look at this one, it
spells danger(arithmetc scale). Don't trust you semilog scale.
Or should one say"I use semilog scale, the
buy/signal that shows up on you arithmetic scale has no
significance.
What I have learned is to use semi log scale
for extended *price ranges*. I haven't heard the argument with regard to
time before.
Interesting...
