Yeah I know, and TA is any form of analysis used to make trading decisions that is NOT based on company fundamentals. Price action fits that bill exactly.
TA is a slippery jungle of delusion for most. Hindsight bias is a killer in this business and TA feeds that sinful nature. HOWEVER, if you are a true believer, you might as well proceed in a systematic way. My friend David Aronson's book "evidence based technical analysis" is the only place to start. Almost all of the "educational" material out there on TA is wives tales , delusion and money making schemes ( scammers correctly guess that if you believe in TA, you are an easy mark). READ THE BOOK!!! Or go down the rabbit hole of completely spurious beliefs.
That's one of the better analogies I've heard. Well stated. TA is a science and like any science class in school there were some that excelled and others that played with themselves in the back of the room and paid the smart kids to do their homework.
Opps, forgot to add. In addition to David Aronson's book. My friend janes Altucher's "trade like a hedge fund" is the only other education one needs on how to trade.
Obviously, no real indicator says buy here and sell there. TA is a tool but you need skills to go along with such a tool. Trading takes hard work to master; this isn't an easy profession but I have to say it's better than most.
