I know that One "can" get rich on stocks using a dart board alone, but still I am looking for your opinion.
The answer is
NO because there's no such thing as "using only technical analysis or technical
indicators and nothing else" unless you really did not literally meant such when you used the word
"alone".
You need a complete trading plan that involves risk management, position size management, discipline, proper trading instrument, right market at the right time and many other variables. That stuff is needed with the TA.
Note: You gave no definition of your definition of the word rich. I'm going to assume you're defining such as a multi-millionaire considering that's the typical term for such in the financial world.
Don't get confused. I'm not saying someone can not get rich from TA. There's just too many verified proof of such by traders of the past that did become rich while using TA (e.g. Paul Rotter) with other things. The issue here is your question...can such be done
without any other variable in a trading plan when you said TA alone.
Simply, TA alone can not compensate for those missing variables nor was it designed to work alone. In fact, if you look at the history of TA...those that designed it and using it...they were not using it alone. Thus, I'm always perplexed when I hear a trader say I use TA and nothing else...its just not possible.
P.S. If you reply and give clarification that you didn't really meant...alone...there's already dozens of threads full of debates about that topic.
Most of those debates if mainly due to so much vagueness and different opinions about what is TA, what is a trading plan, what is rich, what is trading for a living, what is chart analysis,
what is technical indicators and so on...its beyond stupidity by now.
