Rainer,,,,,,I agree with everything you wrote in your last post but the bottom line. TA plus sound FA provides an investor with a complete set a tools to make the right calls. There are many here who were wishing that they had sold into the strength but did not. Therefore to call a person who utilizes TA "a fool" is a bit naive since this fool is walking away with your money; albeit short term.
PS: I am not a daytrader, but do have a short term acct.
It cannot take into account unexpected future events. However, it will indirectly inherit expected future events at least somewhat, because market participants' expectations regarding these events are continuously influencing the share price.
Bottom line: A fool with a tool is still a fool.
