Quote from rcanfiel:
This is a thread dedicated to the principle that Technical Analysis (by and large) has little to no value. It is contended that people continue to learn, sell, promote or believe in technical analysis, contrary to the many studies that continually demonstrate little to no <i>special</i> predictive value from TA indicators or chart patterns [also including Fibonacci levels, Elliott Wave, Gann, and probably Volume.]
The consideration of Price action, free of all indicators or other philosophies mentioned above, is not included in the definition for purposes of this thread. This seems to be one of the few ways that many successful traders use that actually works.
Those dissenting will usually try to defend TA via some of the following methods:
1) Stating "of course method a or indicator b has value. You just have to know how to apply it."
2) Anecdotal or testimonial evidence (often unverifiable or presented in an unrealistically positive light), in which a poster says "it works for me" or "I know a successful trader who..." or other variations on this theme. Often the person known may only use a certain technique or a (small) part of his trading method.
3) Throwing mud at a well-designed test by pointing out a perceived flaw or parroting the fine print of such a test. Usually, the poster will ignore other parts of the survey and offer little evidence of their own. This is mostly a distractive technique, not something that would hold up under academic/scientific rigor. To fully discredit something requires equally rigorous evidence, that is accepted by the other knowledgeable individuals in the invest community.
4) Point to some successful guru "who I know used it" However, rigorous independent monitoring is usually absent and longterm tracked performance results will generally be missing, spotty, ancient, or questionable. Or again, the particular method might only be a fraction of the trading methodology, where something else such as money management might explain the outperformance.
5) Use other distracting or verbose arguments that have little value if examined "under the hot lights."
6) Point to a few well-chosen examples of success, when a true test requires a large sample to demonstrate value.
None of these arguments would hold much weight as compared to longterm, rigorous statistical sampling & testing of a mentioned method or indicator, over a diversity of markets and market time periods.
It is further noted that since some 95% of leveraged traders are said to lose their trading capital, and that technical analysis is the preferred method by most traders, that there is a primary link between these two facts.
One definition of Technical Analysis is:
<i>Technical analysts (or technicians) identify non-random price patterns and trends in financial markets and attempt to exploit those patterns. While technicians use various methods and tools, the study of price charts is primary. Technicians especially search for archetypal patterns, such as the well-known head and shoulders reversal pattern, and also study such indicators as price, volume, and moving averages of the price. Many technical analysts also follow indicators of investor psychology (market sentiment).
Technicians seek to forecast price movements such that large gains from successful trades exceed more numerous but smaller losing trades, producing positive returns in the long run through proper risk control and money management.
There are several schools of technical analysis. Adherents of different schools (for example, candlestick charting, Dow Theory, and Elliott wave theory) may ignore the other approaches, yet many traders combine elements from more than one school. Technical analysts use judgment gained from experience to decide which pattern a particular instrument reflects at a given time, and what the interpretation of that pattern should be. Technical analysts may disagree among themselves over the interpretation of a given chart.</i>
