Build Vertex Core

Kettleburgh · Suffolk

Volume first. Then participation.

Build Vertex Core runs small-room training in volume analysis: how to read whether a move had a crowd behind it, and when a busy tape still failed to pay. The work happens on paper, with the London session as the spine.

What the room is for

A tall bar is not a verdict

Most people who write to us already keep a chart. What they cannot yet do is say whether the session’s volume was initiative, responsive, or empty. Market participation signals are that distinction, spoken in ordinary English over a printed page — not a new overlay, and not a list of entries.

We work from UK cash hours and a gilt future so the clock is honest. Relative volume at a given half-hour matters more than the tallest histogram on the sheet. Effort versus result on the London open is day one’s spine. Climax volume is allowed only when effort, location, and a failure of result are all on the page.

If you want someone else to take the trades, this is the wrong address. If you want to stop decorating Tuesdays, request a place on the workshop or send a fortnight for a chart review.

  • Maximum ten people · printed chart pack · follow-up call

Reviews, a Tuesday circle, a four-week block

These sit beside the workshop rather than replacing it. A first lesson still belongs on the two-day floor.

The pre-work was more useful than the sandwiches. Bringing three of my own sessions meant I could not pretend the method only works on their chosen examples. I would have liked a third day on US hours; two days is tightly packed if you are rusty with a ruler.

Pages you can mark against

Short pieces on quiet Tuesdays, climax volume, relative volume, the London open, and a journal short enough to survive a half-term.
