A recognizable shape formed
Highs, lows, and zones lined up in a way that matches a named pattern's outline.
Classic Patterns and Breakout Signals
A head and shoulders, a double top, a triangle — these are shape names, not trading instructions. Learn to recognize them as candidates worth watching, and to separate a completed shape from a confirmed break.
- Recognize a handful of classic continuation and reversal shapes.
- Explain why a pattern is a descriptive candidate, not a prediction.
- Distinguish a completed shape from a confirmed break of it.
- Connect a pattern back to the zones and structure from earlier lessons.
- Write an invalidation condition for any pattern candidate before acting on it.
A Pattern Name Is Shorthand for a Shape You Already Learned to Describe
Every classic pattern — head and shoulders, double top, triangle, flag — is really just a specific arrangement of the highs, lows, and reaction zones covered in earlier lessons. The name is convenient shorthand, but it doesn't add any new certainty beyond what those individual pieces of evidence already supported.
A candidate worth watching
The shape suggests one possible next-step scenario among others — not the only one.
That the pattern will complete
Plenty of recognizable shapes never finish forming, or reverse before any breakout happens.
Four Classic Shapes, Read Candle by Candle
Each shape below is built from the same raw material: highs, lows, and a boundary zone. Read the candles first — the name is just what you call the arrangement once you can already describe it.
Head and Shoulders
Price rallies to a first peak (the left shoulder), pulls back to a boundary, rallies higher to a second peak (the head), pulls back to roughly the same boundary again, then rallies to a third peak that stays below the head (the right shoulder). The line connecting the two pullback lows is the neckline — a zone, not one exact price. A close below it is the earliest evidence of a possible reversal, not proof of one.
Left ShoulderHeadRight ShoulderNeckline zoneNeckline ~95.6
Neckline drawn as a zone (95.1–96.1), not one exact price. Close below it is the earliest evidence, not a certainty.
Double Top
Price rallies to a peak, pulls back once, then rallies again to a comparable peak before turning down. Two highs at roughly the same level with one pullback between them is the whole shape — nothing about it guarantees the second decline continues past the pullback low.
Peak 1Peak 2Neckline zoneNeckline ~94.6
Two comparable peaks with one pullback between them. The pullback low is the reference zone, not a guarantee it holds.
Ascending Triangle
An upper boundary stays roughly flat while the lows underneath it step progressively higher, squeezing the range narrower with each touch. That convergence describes shrinking room to move — it does not decide which side price eventually leaves from.
Upper boundary (flat)Rising lowsUpper boundary ~100.0
Flat top, rising lows converging toward it. Convergence describes a squeeze — it doesn't pick which side price leaves from.
Flag
A sharp, strong move (the flagpole) is followed by a short, narrow pullback that drifts gently against it (the flag). The pause is brief relative to the move that preceded it — but a pause is still just a pause, not a guarantee the prior move resumes once it ends.
FlagpoleFlag channel
Sharp flagpole, then a short down-sloping channel. A pause inside a move — not a guarantee the pole resumes.
Match Four Descriptions to Four Classic Shapes
Read each plain-language description first, then pick the pattern name that fits — the reveal explains what the shape does and doesn't tell you.
Pattern Shape MatcherMatch the description to a classic pattern name — then read what it can and cannot tell you
A peak, a higher peak, then a third peak roughly level with the first, with a connecting line beneath all three.
Some Shapes Describe a Possible Reversal, Others a Possible Continuation
Head and shoulders, double tops, and double bottoms describe a possible change from one state to another — they still need the same evidence any state change would.
Triangles and flags describe a pause inside an existing move — they don't guarantee the prior move resumes once the pause ends.
Neither family is inherently more reliable — both are read using the same width, depth, and reaction-zone evidence from earlier lessons.
A Pattern's "Neckline" or Boundary Is Just Another Zone, Not a New Kind of Certainty
Whatever a pattern's reference line is called — a neckline, a trendline boundary, an upper or lower edge — it inherits every caveat already covered: it's drawn from chosen points, it has width rather than being one exact price, and crossing it once doesn't automatically confirm anything.
Draw the boundary as:Picked from a single wick low — looks precise, but a different chosen point moves it
Identical price data — only how confidently the boundary is drawn changes.
How Much Evidence Does Each Scenario Actually Provide?
Pick a case and judge how confirmed the break really is. More evidence should raise your confidence gradually — it shouldn't jump straight from "nothing" to "certain."

A "Measured Target" Is a Geometric Projection, Not a Promise
Some patterns come with a common rule of thumb for projecting a target distance after a breakout — for example, copying the pattern's height beyond the breakout point. That's a piece of geometry copied from history, not a law the market has to obey. Price can fall short, overshoot, or reverse well before reaching it.
Pattern height: 5.5Measured target (projection): 89.0Actual low: 90.5 — stopped short of the projection
The target is the pattern's own height copied below the breakout — a geometric guess, not a floor price has to reach.
Five Tests Before You Name the Pattern
01
Data
Product, venue, timeframe, and session the shape was observed on.
02
Points
Which specific highs, lows, or zone touches define the shape.
03
Boundary
Where the neckline or edge sits, and how much width it has.
04
Confirmation
What would count as a close, a hold, or a retest — defined before the fact.
05
Invalidation
What would make you drop the pattern candidate entirely.
A Named Shape Still Needs a Defined Test
It repackages highs, lows, and zones you already know how to describe on their own.
A shape finishing forming is not the same fact as a level being closed beyond and held.
Projected distances are copied from a shape's own height, not guaranteed by any market rule.

Question 1 of 3
What does correctly naming a chart pattern actually add to your analysis?
Question 2 of 3
Price wicks briefly below a pattern's neckline on one candle, then closes back above it in the same session. What is the most defensible read?
Question 3 of 3
Price closes clearly beyond a triangle's boundary, comes back to the edge, and holds above it. A measured-move target sits a few percent further on. Which read is most defensible?
Stuck? Ask Mira to Break It Down
Describe the shape, the boundary, and what happened afterward, and Mira can help separate what's confirmed from what's still just a candidate — it won't tell you the pattern guarantees an outcome.

Support and Resistance Aren't Walls
Explain support/resistance as historical zones where buying or selling reactions occurred, and explain why a zone can fail and why a breakout doesn't guarantee continuation.
