What a pattern is made of
Part 04 spent seven chapters on a single session. A chart pattern is the same enquiry at a different scale: not what happened on Tuesday, but what the shape of forty Tuesdays records.
Take the path 07.02.01 used. Closes climb for several weeks from about ₹92 to ₹120, fall back to ₹108, rise again to ₹119, and ease to ₹112. Drawn as a line, that is an M. Drawn as forty candles it is forty separate arguments, most of which nobody would remember.
The M is a compression: many sessions reduced to the few facts that survive being stood back from. Those facts are real. Price did reach about ₹120 twice, and it did fall to ₹108 in between. Nothing in the shape is invented by drawing it.
Forty sessions, one outline
The same illustrative history as 07.02.01, drawn as closes. The dashed line is the middle low.
Everything this drawing shows is true. The lesson is in what it had to leave out to become this legible.
What the compression threw away
A line of closes is the most compressed chart there is, and 03.01.01 already said what it costs. Each point is one of the four numbers a session produced. The open is gone, the high and low are gone, and so is everything about how the session got there.
So the ₹120 on that line may have been a session that opened at ₹114 and closed on its high, or one that reached ₹126 intraday and gave it all back. Those are different days and the line draws them identically.
Gone too: whether any of these sessions gapped, and how much was traded on each. Part 08 takes volume properly. For now, notice that the shape a reader finds most convincing — a clean M — is the one produced by throwing the most away.
A pattern is not a summary of the sessions inside it. It is what survives deleting most of them.
Where “supply and demand” is doing real work, and where it is not
The standard explanation of any chart pattern is a sentence about supply and demand, and part of it is simply true. Price reached ₹120 twice, which means shares changed hands there twice. Somebody was willing to sell at that price on both occasions, and somebody was willing to buy. 04.06.01 established this for a single wick and it holds just as well across forty sessions.
The part that is not established is everything usually said next. That a large seller was waiting at ₹120. That the same seller was there both times. That they had a quantity still to place. That anyone at all noticed the first high when the second one formed.
None of that is on the chart. The record says a price was reached and not held. The story says why, and the story is added by the reader.
This is not an argument against the story. It is the same discipline Part 04 ended on: a shape permits an account of what happened and does not prove one. At chart scale the temptation is stronger, because forty sessions of evidence feels like more than one session of evidence — and it is more, of exactly the same kind.
The one thing a pattern adds that a candle cannot
Time. A candle records a session and has no memory of the one before it. A pattern is built from the relationship between sessions that are weeks apart, and that is a genuinely different object.
It lets you say things a single board never could: that this price area has been tested twice, that the second test went less far, that the decline between them was real rather than a pause. Those are facts about the chart, checkable by anyone with the same data.
What it does not add is certainty, and it is worth being clear why not. Forty sessions of a shape forming is forty sessions of description. The extra evidence is evidence about what already happened, and there is no quantity of that which becomes evidence about what has not.
