You have the "strategist TA" person in the meeting. You also have the traders at their desks at the firm managing the position via TA and via those other data/resources they have access too. Thus, its more than someone with the title "strategist technical analyst" giving his/her perspective in a decision process meeting about what to do next. In fact, more often than not the decision has already been made...its now just a "when" to do it.
Not all firms are like that but many are...they are doing much more with TA than just showing charts at a meeting.
As to the issue about
account destruction for the
retail trader...the reasons do not involve TA.
In contrast, most retail traders fail at trading because of any of the following reasons:
1) No trading plan
2) Poor risk management
3) No discipline
4) Inadequate trading tools (this gets into that "other data/info/tools")
5) Poor business management of trading
6) Poor stress management
7) Trading the wrong trading instruments
8) Poor understanding of what moves the markets (Hint: Its not someone using TA).
9) Poor adjustments to new regulations and exchange rules
Simply, TA if listed as the reason to failure...its at the bottom of the totem pole. By the way, there's a growing list of traders here that use charts but do not believe they are using TA. Therefore, what is TA and what is not TA...its starting to quickly get muddy and I predict more debates about TA mainly because most do not know what it is or have developed their own opinion of what constitutes "using TA".
My point, there are just as many traders failing at the business of trading and they don't even use TA nor believe in it. Therefore, its logical to think that the reasons for failing at trading is not dependent upon TA.
