Doesn't really matter if you know how to construct them or not. Unless everyone is drawing the same lines on the same charts in the same timeframe using the same bar intervals, then trendlines can't provide support or resistance.
The job of a trendline is to show the direction and strength of the trend and also to show when the strength of the trend is lessening, changing, reversing. That's sufficient.
Lets say you are learning about making money. You see a post such as this.
What to do?
Well what is the most important thing for you is to move along always seeking higher ground. This is an admonition to: "not get stuck at any time and especially in a mess like this"
"Do not get to a place where this set of beliefs is your picture of what it is all about."
The immediately above two quoted comments have little value compared to what a person has to do to get to a powerful, successful foundation for making decisions.
I will post soon the questions a person has to consider to get out of this mess. By doing so, I believe, anyone then has a chance to get to higher ground. You also get to see how anyone who is not stuck can be at inquiry for learning.
It is not ever important to have a viewpoint just to "be right" or "correct". What is important, however, it to be open to consider growth from a sound foundation that is built iteratively over time. If you strive to be better and more you do get to a place where you can learn about more and more things as you assert yourself to broaden and deepen your understandings.
"Readiness" is abig deal in growing into expertese. at the beginning of the path most stuff you "see" cannot come into focus for you because of where you are. Later, it will come into focus as it becomes surrounded and supported by collateral facets.
This post, above, that I am responding to is a mess. As a reader, you need to be able to not infuse your basis of operation with wrong stuff and, secondly, you need to be able to build past this mess by adding to your belief foundation correctly. This will be a good experience in "knowing how to know". You must always know how to know as you grow.
