Hi Mark, sorry about that post. Not fair and I regretted it just as I
hit the send button.
The distinction about objectivity and subjectivity about price data
is ambiguous. Data are certain, as long as they have they have been
well recorded, but per se are of little significance. You need a
model, a theory to interpret them. When you choose to apply a trend
definition you are interpreting them in a subjective way, someone
else could talk of trends in prices as 'windmills of the mind'.
Every mechanical rule is a subjective choice made upon a theory. The
fact that is applied sistematically doesn't mean it's objective. It's
only measurable as long as it applies to the past.
I think that prices are a historical process and there is nothing
like an urn and a set of white and black balls. The system is open
and undefined and when someone makes only use of past prices he's
simply deciding to act on the basis of a well defined set of
information, on the ground of a theory that assumes the existence of
a stable generating process, and is forming his expectation, positive
or negative, accordingly.
In all this process there is not so much objectivity, in my opinion.
in about the future he's moving along the same line as one
