Lol. The ego is strong in this thread.
FYI more than one way to make money on markets. What might look like sorcery or witchcraft to one trader might be a license to print money for another.

You can't deny that trend lines are subjective and will vary from one person to the next or even from one day to the next with the same person.
Saying that people haven't learned to draw trend lines properly and not explaining further what's meant by that seems like an odd comment.

On the bottom right, I "pretended" there was a spike low which frequently happens. If you are to include all prices, this would greatly change the TL compared to if you only use the full body.
