Pencil marks for trends, channels, and market structure
On Tuesday and Thursday evenings the room on Haeundaehaebyeon-ro lays out the same kind of sheet: a price path, a pencil, and enough quiet to decide whether a trend is still a trend and whether a channel has earned its second line. The October studio runs for six of those evenings.
The three-week desk
One chart pack, marked until the labels hold
The Trend, Channel, and Structure Studio is the lesson people cross the city for. Lee Haeun keeps the order strict: a trend first, a channel only after the touches exist, then the swing sequence that shows whether that picture is still the same picture. You leave with the paper, not with a slogan.
Shorter sittings
If you only need the channel, or only the correction
Channel Drawing Clinic
A half-day at the desk spent only on parallel channels: anchors, touches, and the difference between a channel and two lines that merely look related.
Structure Markup Review
Ninety minutes with your own marked charts. We correct trend lines, channels, and swing labels you have already attempted, and we stop where the marks run out.
I stopped adding a middle line. Once the channel had two honest touches, extra graphite only hid the swings.

A channel is two lines that agree
The second line of a channel has to touch the path for a reason. Parallel on its own is only a drawing.

When the swing structure changes character
Higher highs and higher lows are a description, not a medal. The useful mark is the first swing that breaks the description.
