I attach an experimental indicator that draws trend lines.
The indicator is based on the famous SHI Channel
by Shurka & Kevin, so it uses fractals instead of highs and lows.
The lines are buffers, not objects, so they are stable.
I 'coded' this thing in 2015, so it's been around for a while.

The indicator is highly experimental, so for now I have decided
that access will be limited until the end of August.
