Most fail because TA is just a tool. Tool is not enough to make a master. It is so obvious and simple, but most don't like to hear it, cause they consciously or unconsciously hope there's a way to get all for nothing without much efforts. Fact of life: those 95% are lazy crowd.
Sometimes prices move without forming lower highs , or higher lows , either leaving the trend trader without an entry , because the move was in a straight line or making a move and reversing ( and also catching the trader in a false break).Price fluctuations patterns are repeatable in hindsight t/a trading education.
Some body else said trends only exist with price action , so trend does not exist in foresight , or it exists with same set ups sometimes it materialises but on other times it fizzles out .In hindsight you can see a trend!
Another clown .....100 % of trends succeed in hindsight , backs it up with non price action philosophy and non related comments!
So one can see a trend that does not exist , but another can not see a trend if it exists.So it is some kind of an illusion or some magic .....which worked with Mr Turtle in the past , then it stops working and lost Mr Turtle millions.
Wrong. 100% of the trends are successful. What you believe are "failed trends" never was a trend in reality. Look for flaws in your analysis. And while you are not a consistently profitable trader, you better shut your mouth, sit and listen with attention and gratitude to people who know what they talk about. Be happy someone who knows what trading is about bothers to talk to you at all. That's what I did a few years ago when was just learning to trade.
