Unfortunately debates about "this" vs "that" are still conducted by people who are struggling with "likes" and "dislikes" (imbalance between the two lobes of the mind) which most people do by the way.
The most successful traders are those who can use both, have no preference, understand that anything works but everything is variable and can be used in a certain situation and by different people.
Your two brain sides are each responsible for a different thing, no wonder some people let their profits flow all the way then...let their loss run all the way. While others cut both their loss and their profits too soon. Why is that happening? because the hardest thing to do is to find balance and create balance between the two sides of the brain. One side is responsible of creativity and imagination (letting go), you need to use that for your profits, the other side is responsible for managing the known, you need to use that for cutting loss.
The most fanatic and stubborn people, be it with artistic brains (lets profits and loss flow) or mathematicians brains (cuts both) are those with the greatest losses because they got married to that part of the brain.
The most open minded, flexible people with the ability to adapt, unlearn, re-learn are those who can adapt faster to market change and find ease in transforming from an inefficient trader to an efficient one.
It is not TA that works or does not, it is the way you use it that decides if it can be useful (note i did not say holy grail or secret strategies) or not. Same goes for any form of analysis.
