Doji clusters on familiar SET names

Thai students often arrive with a list of SET50 names they already follow. That is useful. It is also a trap if the lesson turns into prediction. A doji on a household bank chart feels more important than a doji on an index you never look at. Importance is not information.

During the second Saturday we print three weeks of daily bars for two widely held names and ask the table to circle every doji, then to write one sentence that does not contain the words up, down, buy, or sell. The sentences that survive tend to sound like: ‘range collapsed; next bar must show who kept the close.’ That is the whole point of the drill.

We keep foreign examples in the pack so the shape is not tied to one exchange. The rule does not change when the currency does.
