A velvet-lined classroom at night with a lacquered table, copper lamps, and large paper sheets of smooth curves

Swing marks first. Volume only after the structure is named.

Synap Vertexfield Academy Co., Ltd. runs a small evening classroom for tech analysis training in reading market structure and volume. Charts are printed. Pencils do the naming. The cloth stays over the volume bars until the swings are honest.

How an evening moves

The cloth comes off on a schedule, not when the room gets restless.

Kanya Vorasak opened this room in 2016 so neighbours in Mueang Samut Prakan could learn to name a swing without a ticker shouting at them. The order of the night has barely changed. Structure is marked in silence. Volume is a second pass. A tall bar never gets to overrule a low that is still holding.

01Chairs in. The market for the night is already on paper. Phones stay face down.
02Swing highs and swing lows only. A peak inside an unfinished push is written as a pause.
03The cloth lifts. Effort is the height of the bar. Travel is how far price went. A climax that stalls is labelled a stall.
04You leave with your own pencil marks, including any swing the room agreed to leave unfinished.

The long sitting

Six evenings for one market.

Structure and Volume Cohort

Six evening sittings in Mueang Samut Prakan for adults who want to name a swing before they read the volume under it.

Six evenings across three weeks · 18,900 THB for the full cohort · 10/1 Mueang Samut Prakan District, Samut Prakan 10270

Evenings one and two stay on structure. Evenings three to five put volume against those marks. The last night is your chart, not a sample from the drawer.

Shorter ways to sit

A single print, or ninety minutes with your own sheet.

Volume Print Clinic

One evening for people who can already mark a swing and want a slower look at effort, result, and a climax that did not travel.

2,400 THB for the evening

One-to-one

Private Structure Sitting

Ninety minutes at the same table with one teacher, spent on a chart you bring, marking structure first and volume only where it changes the label.

4,500 THB for ninety minutes

From the August cohort

Ploy took the sheet home and did not scribble over it.

I took the August cohort after a year of marking charts alone in a notebook that had become all arrows. On my own sheet, a higher high in gold had almost no participation under it. We left it labelled as a pause. The following week price came back to the shelf we had underlined. I still think evening five ran long, and my bus does not love a 21:00 finish, but the sheet I took home is the first one I have not scribbled over the next morning.

Recent field notes

Pauses, climaxes, quiet turns.

9 September 2026
A dry pullback still needs a location
Light volume on a pullback is only interesting next to a swing the room has already named. Without the location, the dry-up is just a quiet hour.
28 July 2026
Marking a change of character on a quiet afternoon
A change of character is a break in the rhythm of swings, often on ordinary volume. The afternoon practice set is built around one.
2 June 2026
A volume climax that did not travel
Effort without travel is a different mark from a climax that runs. The print clinic exists for that difference.
12 March 2026
When a swing high is only a pause
A new extreme is not a new swing until the prior low has been respected or broken. The cohort spends a whole evening on that distinction.
