Markup mistakes that keep showing up in Bang Bua Thong

I keep a running list on the inside of a cupboard door in the classroom. It is not a curriculum. It is the mistakes I still walk toward first when I sit down beside someone on Day 2.

Treating every wick as a level is the loudest. A long upper wick on the daily is information about rejection in that bar; it is not automatically a line to draw across the page for the next month. We ask: did later bars accept that area, or was it a single probe? If it was a probe, a note in the margin is enough.

Marking every pivot comes next. A weekly chart needs its obvious swings, not a zigzag that turns the page into a seismograph. If you need a ruler to see the last swing, you have probably marked noise. Step back the length of the desk. The structure you can still see is the one we want.

Ignoring the left side of the weekly is quieter and more expensive. People mark the last three months because that is what their screen defaulted to. A range that began last year still explains why this month’s daily “breakout” keeps failing. We keep a longer weekly print on the side table for that reason.

Two more: writing a bias that cannot be cancelled (“bullish while the market is bullish”), and copying Niran’s wall lines onto a market he was not marking. The wall is a demonstration. Your page is your market. If gold was on the wall and you trade a Bangkok-listed stock, the levels do not travel.

None of this is moral. Charts get messy when you are tired. The cupboard list is there so we can point at a habit quickly and return to the page, which is the only thing that improves the next Tuesday.
