Here are some more lines to float your boat:
With all my respect...
There is too much subjectivity involved
- even in drawing of "proper" trendlines.
How to draw a trendline?
There is 1000 + 1 ways of doing so,
and they all could confuse and mislead.
So, what to do with all these angles?
With very few explanations, I don't have a clue,
what to do with all this stuff.
Price went up 30 degrees, then - down 30 degrees.
And so what?
What I suppose to do after that?
I know, that MO is master of puzzles,
but I cannot implement puzzles in real trading.
If someone is smart enough to grasp this complex
concept from a few confusing charts, he's great.
I'm not the one, and I have a courage to
say it openly.
There is interesting theory of "price pace"
by Toni Hansen, where she explains
(in plain English with lots of examples),
how to determine future price trend, based
on previous movement and angles.
But in absence of any indicators, even it
looks like a puzzle for me.
I like to solve puzzles once only,
after that they should be automated
and be forgotten, blindly showing me the way.
No stress, it's just my point of view.
