A moving average you can explain with a pencil.

Eight Tuesday evenings in a ten-seat room. The work is trend mapping with moving averages: length, slope, lag, and ribbon spacing, on printed closes rather than a live screen.

Reserve a Tuesday seat

An evening in the room

Phones on the brass tray, length in the margin.

At 18:15 Arun takes the phones. Niran puts down a sheet of daily closes from a finished year, with the period left blank on purpose. You write how much noise the line is allowed to ignore, then you add the window. The velvet holds the sound of pencils. Nobody calls out a price target. The hour ends at 20:30, whether the division is tidy or not.

The October desk meets on Tuesdays from 6 October through 24 November 2026. One seat is 18,500 baht. The address, the deposit, and the eight subjects sit on the class page.

The long class

Moving-Average Trend Desk

Niran Chaisiri keeps evenings 1 to 4 and the final explanation. Malai Somsri takes the lag, the exponential redraw, and the ribbon. You go home after the eighth night with the marked pack, not with a list of names to chase.

Other ways into the same marks

A Saturday, or one sheet.

Saturday Ribbon Workshop

One day with a spacing card. Malai refuses the word compressed until the gap fits the notch. Next dates are 3 October, 7 November, and 5 December 2026.

Single Chart Sitting

Ninety minutes, one printed chart, one instructor. Bring your own sheet or use one from the drawer. Thursdays, by appointment.

I still mix the 20 and the 50 when the sheet is noisy. What changed is that I write the length before I draw, and I stop treating a cross as an order.

More notes from the table

From the journal

The average is late because the window still holds old closes.

Evening 5 counts the sessions between a bend you can already see and the date the 20-period slope goes flat. That count is the lag. It is arithmetic, not a mood.
