Mentis Weavefield Academy Co., Ltd.

A ten-seat chart room in Bang Phoa. The registered company has taught trend mapping with moving averages since 2016. The habit of the place is older by two years.

How the company began

In 2014 Niran Chaisiri, then a back-office clerk handling listed shares, rented a room above a stationery shop near Bang Bo market. Colleagues wanted a slower way to read a moving average than the arrows passed around the office. Tuesday evenings were informal, paid in cash for paper and lamp oil, and limited to people who already had a day job.

In 2016 that practice was registered as Mentis Weavefield Academy Co., Ltd.. The year on the company papers is 2016. The stationery-shop room remained the classroom until 2019, when the class moved to the present address in Bang Phoa. Malai Somsri joined the same year to teach exponential averages and ribbon spacing. Arun Thepchai came in 2021 to keep the printed packs, the seat book, and the Wednesday open desk.

What the room is for

The academy teaches adults to describe a trend on a chart: which length they chose, where the line sits, whether the slope is rising, and how many sessions the average lagged a bend they can already see. Lessons use historical daily closes that have finished. A live price has no role in the hour, because a moving number ruins the arithmetic.

Students often follow names on the Stock Exchange of Thailand, and a few follow currency pairs. The academy’s work is the classroom hour. Brokerage accounts, funds, and instructions to buy or sell stay with the firms and advisers a student already uses. Decisions about money stay with the student.

How the work is done

Classes stay at ten seats so an instructor can see the margin of every sheet. English is the language of the lesson. Niran and Malai will repeat a Thai phrase for a room direction — where the tea is, which drawer holds spare pencils — and then return to the chart in English.

Values in this room are ordinary and strict. The length is written before the line. A crossover is described only after each slope. The table talks about slope and lag. Sheets are shared as teaching copies for the people in the room.

Niran Chaisiri

Principal instructor. He still begins a new desk by making the table compute a short simple average without a calculator. He leads evenings 1 to 4 and the final spoken explanation.

Malai Somsri

Chart instructor since 2019. She teaches lag, exponential weight, and the ribbon, and she keeps the spacing card that decides whether a bunch of lines may be called compressed.

Desk steward. He prints the packs, writes the seat cards, and opens the room on Wednesday for students who need to copy a marking they missed. He does not teach the averages.
