While I would agree that for the most part indicators and systems are
not the cause of price action, imho good indicators and systems are
designed to recognize high probabilty realities burried in noise ...
As far as the why's are concerned ... I already know a myriad of
reasons it's not like all economic and fundamental data which by
their nature lag not only reality but price as well. One could spend
a lifetime looking for the answers to the why's and never derive
anything useful for trading / investing. As a result I'll leave the
why's to the philosophers and concern myself with the when's and the
what's.
