Filed under continuation. Read as a reversal.

Rahul finds a wedge in the chapter on continuation patterns, reads what it is supposed to mean, and comes back confused. Everything he can find says a rising wedge is bearish. Lakshmi tells him the confusion is correct.

Both are true, and the reason is worth more than either.

The shape

A rising wedge has both boundaries sloping up, converging, with the lower edge rising faster than the upper. A falling wedge is the mirror: both edges sloping down, converging, with the upper falling faster.

So it is a triangle whose flat side is not flat. Where an ascending triangle has a ceiling being pressed into, a rising wedge has a ceiling that keeps giving ground — just not as much ground as the floor is gaining.

That single difference is what the books read. Price is still making higher highs, so the trend is technically intact, but each advance is smaller than the one before while the pullbacks shrink faster. The move is running out of room rather than out of direction.

Higher highs, and a floor catching up

The dashed line runs through the rising lows — this example's stated test. The fainter line runs through the rising highs.

The highs gain ₹5 then ₹3. The lows gain ₹8 then ₹5. Both are rising; the gap between them is closing.

Why it is filed in the wrong chapter, and why that is fair

A wedge appears in the continuation chapter of most indexes for a structural reason: it is a converging pattern, and converging patterns — triangles, pennants — live together. It is shelved by its geometry.

It is then read as a reversal because of what the geometry records. A rising wedge inside a rise is an advance whose increments are shrinking; the usual reading is that it more often ends the rise than extends it. A falling wedge inside a decline gets the mirror reading.

Both are defensible and neither is settled. The shelving is about shape and the reading is about outcome, and once you see that, the contradiction stops being a puzzle. It is also a small demonstration of something 04.07.01 said about candlestick catalogues: how a reference is organised is a fact about the reference.

What follows practically is that a wedge is the one pattern in this chapter where the stated test should be written for the direction the reading expects. Here that is a completed daily close below the rising lows, not above the highs.

The same six points, drawn three ways

Now the part that matters more than the naming, and it is the strongest case in Part 07 for what 07.01.04 argued.

Take the six swing points on the chart above: highs at ₹80, ₹85 and ₹88, lows at ₹70, ₹78 and ₹83. Those numbers are fixed. The lines are not.

Draw both lines through all three of their points and you have the converging wedge above. Draw the upper line through the first and last highs only, ignoring the middle one as an overshoot, and the slope changes enough that the lines barely converge — a rising channel, which most books read as continuation rather than reversal. Use the last two of each instead, on the argument that recent swings matter more, and the two lines are nearly parallel.

Three honest procedures, three names, one unchanged set of prices. Nobody has cheated in any of them. This is exactly what 07.01.04 measured when moving a tolerance turned twenty double tops into fifty-eight — the sample is a property of the procedure, and here you can watch it happen on eight closes.

The prices were the same in all three drawings. The disagreement was never about the market.

What survives all of it

Less than the vocabulary suggests, and it is still worth having.

The increments are shrinking: ₹5 then ₹3 on the highs. That is arithmetic on the swing points and it does not depend on any line at all. It is the observation the wedge was invented to capture, and you can make it without drawing the wedge.

The apex constraint from 07.03.02 applies unchanged — converging lines meet, and that meeting is a deadline fixed the moment you drew them.

And the honest summary of the naming problem is not that wedges are useless. It is that which name you reach depends on choices you made before the market did anything, so the choices should be written down first, as 07.01.02 said about the lookback window and 07.02.01 said about the boundary. A name chosen after the break has not been applied to the chart; it has been fitted to it.

Where this leaves the chapterFour pages in, every pattern has turned out to be a pause whose name arrives afterwards, drawn with lines somebody chose. The last page takes the most subjective shape of all — one whose defining feature is a word with no geometric definition at all.
Remember

A rising wedge has both edges sloping up and converging, with the lows gaining faster than the highs; a falling wedge is its mirror. It is shelved with continuation patterns because it converges and read as a reversal because the increments are shrinking, and both are defensible. The deeper lesson is on the drawing: the same six swing points support a wedge, a channel or a near-parallel drift depending on which touches the lines use, so the name is a property of the procedure rather than the prices.

Everything this chapter has told you, in order

  1. 07.03.01A continuation pattern is a pause that was followed by a continuation.
  2. 07.03.02A line through two points is a fact about the pencil; a line through four is a fact about the chart.
  3. 07.03.03The rectangle is the only pattern here that admits, in its own geometry, that it does not know.
  4. 07.03.04The prices were the same in all three drawings; the disagreement was never about the market.
