Most (not all) TA bashers do not believe price action, s/r levels, trendlines or anything else on a chart et cetera as being under the umbrella of Technical Analysis.
TA bashers typically view indicators as the only source of TA when in fact
most of TA involves just price on a chart and nothing else.
I'll explain later in this message about why indicators are so darn popular.
In fact, any time someone looks at a chart to form an analysis about the price action, use a chart to help determine a trade entry or uses a chart to just develop a simple opinion...
They are using TA.
Here's another issue that is constantly ignored by those that don't believe TA works along with confusing many TA bashers that meets a profitable trader that uses TA.
Profitable traders using TA are not using TA all by itself.
In fact, TA is just a part of their trade methodology.
Thus, to challenge those types of profitable traders via scientific testing requests while ignoring all the other things involved in a profitable trader's trade methodology is just
silly or poor research skills.
Simply, a researcher needs to make a choice...
* Test TA all by itself while ignoring all the other inputs in a profitable trader's method or to use the classic price action exclusion tactic to concentrate only on those that use indicators.
* Test TA as it is actually used in real trading conditions with all those other inputs (e.g. trade management, discipline, proper capitalization, money management, position size management, market experience et cetera).
Both of the above can be tested but one obviously will be much easier or simpler while the other sometimes called voodoo or art.
Doesn't matter to a profitable trader if TA is science or art. The issue to them is how to make it a useful part of their trade methodolgy puzzle.
Thus, it's not difficult to understand which of the above will be researched by a TA basher or by someone that doesn't believe TA works.
Another problem is that there are too many profitable traders giving a false impression that profitable trading involves only entry signals.
That simplicity is what also attracts new traders...many of whom will call it quits on TA not because TA failed but because they never learned how important those other inputs are that I've mentioned above.
Thus, don't fool yourself into thinking 90% or whatever that fails is due to TA failing...
It's due to the fact that traders spent too much time on TA all by itself while forgetting that TA was designed or intended to be used as a confirmation tool to visualize something they already knew.
Therefore, my opinion is that those other inputs are more important than TA.
Why are indicators so popular in comparison to other types of TA???
Marketing, marketing and more marketing and it's an excellent way to lure in new clients for charting program vendors...
I'm sure you've all seen it among the lower tier data providers while most of the more expensive data providers concentrate their marketing efforts on the integrity of the data itself.
P.S. I don't like indicators and I'm a price action only trader that uses TA.
TA works well when everything else is in place.
