The measurement
Take the lowest price, the highest price and the last price. Ask how far up the distance between the first two the third one sits.
Tuesday ran from ₹21.60 to ₹23.40 and finished at ₹23.10. That is ₹1.50 above the low, out of ₹1.80 of range: 83% of the way up. Written out, it is (last bid − lowest) ÷ (highest − lowest).
That is the whole arithmetic, and it is worth noticing what it uses. Three of the four numbers, and not the open. The first bid of the session plays no part in it at all.
Drag the last bid, and watch the one number
The first bid, the highest and the lowest are fixed. Only the last bid moves — and with it, the only measurement this lesson cares about.
Thirds are a convenience for talking, not a boundary in the market. Nothing happens at 33% that does not happen at 34%.
Why this one and not the others
Each of the four numbers answers something. The open says where the period was cut. The high and the low say how far it travelled — that was 04.01.03.
Close location answers a different kind of question: of everywhere the session went, where did it stop? A session that reached ₹23.40 and finished at ₹23.10 ended up holding almost all of its own travel. The same session finishing at ₹21.90 would have given nearly all of it back.
It is also the measurement that survives comparison. Range is in rupees and cannot be compared across instruments; close location is a proportion, so 83% on onions and 83% on anything else mean the same thing. That is unusual on a chart and it is why the number travels so well.
Almost every name you will meet in this Part is a statement about where the close finished inside the range. Learn the number and the taxonomy stops being a list to memorise.
What it is not
It is not a claim about people. A close near the high is often described as buyers having the last word — a vivid description, and an interpretation that the board cannot confirm. There are no participants in four prices.
It is not a claim about the path. 83% says where the session stopped, not that it climbed there, not that it stayed there, not that it got there last. That is 04.01.05.
And it is not a claim about tomorrow. Lakshmi's line applies here as everywhere: her board tells you what happened today, and it has never once told her tomorrow's price.
What it is, is a checkable fact about three of the four numbers — which is more than most things said about a candle can manage.
- Range ₹21.60 to ₹23.40
- ₹1.80
- Finished at ₹23.10
- 83% of the way up
- Finished at ₹22.50
- 50% — the middle
- Finished at ₹21.90
- 17% of the way up
- What changed between those
- one of the four numbers
A session ran from ₹40 to ₹50 and finished at ₹47. Drag to where the close sits in the range, as a percentage.
Two sessions both finished 90% of the way up their range. The first had a range of ₹0.20, the second ₹3. What do they have in common?
One number, and four lessons of anatomy behind it. What remains is the temptation all of it has been building towards: telling the story of the session out loud.
