OK OK the point was, I think, that there are technical analysts that are just that. Nothing more. All they do is play with lines and have no idea of the real world of trading. There are of course traders that are brilliant at TA and vice verca.
Surely it boils down to what works for you? If it's not exactly technically correct, does that really matter? I have my own original ideas about TA and they work for me and I know they are not technically correct. Trend lines and channels is one of them.
