Quote from jack hershey:
By the numbers...
Informed trader means using a sound basis for trading.
Some 95% of leveraged traders lose their money, mostly trying to use TA methods.
Many of the people who claim to be successful traders confuse being at the "top" due to sheer luck. When 100,000 people trade, there is always going to be a thousand who are in the top 1%.
Many of those people outright lie about success, as is the commonly held belief about many who so claim here on ET.
The sheer volume of fraudulent vendors, trading room providers and others also does not bode well. Few can trade successfully, and sell it instead.
The sheer paucity of successful CTAs, many of whom depend on TA, does not bode well.
The OP outlined what many of the responses would be, because most claimed TA is little more than water dowsing.
Pure price action I have respect for. Indicators, patterns, volume and other things fail when subjected to exhaustive, longterm independent testing. At best, they are "lagging indicators" which predict the past.
I am a scientist and statistician when it comes to trading. Anecdotes, testimonies and the other things in the OP remain pretty much in the realm of belief and delusion. People who lift themselves up as the 5% based on their own testimony never move or impress me. When challenged, they provide much smoke, but little evidence.
Again, I have seen nothing to indicate to the contrary.
