Studio
Stack Mapgrid is a small teaching practice in Samaedam. We run evening classes in technical analysis for people who swing-trade cash equities — SET names, US-listed names watched from Thailand, or both.
Kittisak Rattanapong spent years on a SET proprietary desk where the job was to hold names through several sessions without confusing a wick for a change of mind. When he left the desk he kept a private book, then a few friends asked him to sit with their charts after work. Those sittings outgrew a dining table. The teaching room on Bangkhunthian-Longtalay Road opened so the packs could be printed in one place and the evenings could start after the 16:30 close.
The name Stack Mapgrid is literal in the room: stacked weekly pages, a pencil grid of swing highs and lows. It is not a product name. Nobody here sells a feed.
We do not send a morning list. We do not place orders. We do not teach day trading, options overlays, or anything that cannot be held overnight. Students who arrive hoping Kit will bless a ticker leave with a marked invalidation line or with a wait. That disappointment is part of the work.
Lead instructor · SET-heavy books
Kit leads the intensive and both days of the weekend workshop. He still keeps a small personal book of SET names and refuses to discuss those names as examples in class. Students get printed history, not his live tickets.
Chart packs and US-session notes
Nalinee prepares the weekly packs and reviews homework between Tuesdays. She takes most private coaching when the book is US-listed names watched from Bangkok, including the awkward fact that the cash close lands while this city is asleep.
You write first, naming the equities you hold. We do not ask for account numbers or balances. We ask for a marked chart so we can see where your pencil currently stops. Fees are listed on the fee page. Places in a cohort are confirmed only after the chart sample, because an intensive of eight only works if people will do the homework.
English is the language of the packs and of this site. In the room, Thai is welcome for questions; Kit will still mark the English labels on the page so mixed groups can follow the same close rule.
