Ta is descriptive, ta is not predictive.
very true... and the same applies to FA as well...
the problem is not with analyses , the problem is the unpredictability (in scientific terms) of the subject of analyses - the human nature
so both: TA and FA are designed, and should be used, only to describe to the user what is going on now
and it is up to the user's method to interpret that description and to dictate what action to take now
all attempts to use analysis in order to predict the market imho are destined to fail
