Great post. I think the reason why TA is dismissed by many is because there is a lack of traders with established, audited trading track records. TA is also very subjective and ambiguous, especially Elliot Waves, as there is a lot of room of interpretation.
Btw, do WD Gann, R.N. Elliott, John Magee and Robert D Edwards have trading records or no?
I believe so but I dont have that source.
