The weekly close is a different object than the daily bar
A daily bar records a session. A weekly close records which side of the argument was still standing when the week ended.
People arrive at the Anyang room with a daily chart that has been honest all week and still tells them nothing about the month. The daily bar did its job. It showed the session's range, the open, and the close. The trouble starts when that session is asked to stand in for a longer reading.
A weekly close is a coarser object. Five sessions are folded into one mark. The high of a Tuesday that was given back by Thursday disappears from the weekly body even when it remains visible on the daily sheet. Students who have lived in the daily bar often try to drag that Tuesday high onto the weekly sheet and treat it as structure. It is a session extreme. It is not yet a weekly fact.
In a long-horizon sitting the weekly sheet is opened only after the monthly sheet has been looked at with a finger, not a ruler. The question on the weekly close is plain: did the week finish on the side of the zone the monthly chart already cares about, or did it finish back inside noise that the month has ignored for years? That question does not require a forecast. It requires the student to point at the close and say what it settled.
Volume on the weekly bar is read the same way. A heavy week that closes back inside a range is participation without a decision. A quiet week that closes beyond a zone the market has respected for several quarters is a small mark with a large consequence. The room does not turn either case into an instruction to buy or sell. The mark goes into the notebook as a description.
The practical habit is dull on purpose. Print the weekly sheet. Circle only the closes, not the wicks, for the last two years. Then lay that page under the monthly sheet and see which circles the month still agrees with. Most of the circles lose the argument. The ones that remain are the start of a long-term market study, and they are few enough to remember without a screen in front of you.
If the daily bar is still open beside the weekly sheet, the Tuesday high will creep back into the pencil. Close it. The daily session will be there tomorrow. The weekly close will not become clearer by being surrounded with shorter marks.
