Dislikedfor what it is worth. James does not even use trendlines. Just horizontal support and resistance. I only personally use Extremely clear trendlines for breakouts.

It's funny how they can mislead, specially when drawn on the higher time frames. You mis draw them by a millimeter and it turns out you miss an entire breakout and retest trade on the 4h because all the time price was above your trend line.
They work best when like Mike said they are obvious to the pip.
