Hi DT,
I'm not looking for ways to look into the future.
(I don't recall stating that in my post.)
I am looking for indicators that best identify the
current mode.(either ranging or trending)
If you think this is a useless excersize, then
you should tell Wells Wilder, Tuchar Chande, and all
of the other great technicians who developed indicators
specifically for this purpose.
Secondly, when a person looks at a chart, they describe the
market as Trending or Trading. This is accepted practice and
is only referring to the market in the "recent past".
(Up to the most recent bar)
If you choose to look at a chart in a different way, thats up
to you. But for the sake of communicating with other people,
it is totally acceptable to look at a chart with a price/time
series which slopes from lower left to upper right and say
that the market is generally trending at this time.
I think that most of the participants on this forum already
know that the future is not predictable. (except for
statistical probability gambles)
