Chart Patterns Cheat Sheet, With What Each Pattern Is Actually Saying
Chart patterns are descriptions of how a market consolidates before it does something. Grouping them by what they say about supply and demand makes them far easier to remember than grouping them by shape, and it makes their failure modes obvious.
The short answer
Chart patterns split into two families. Continuation patterns - flags, pennants, triangles - describe a pause inside an existing trend where one side is quietly absorbing the other. Reversal patterns - head and shoulders, double and triple tops, rounding formations - describe a trend running out of participants. Every pattern needs a prior trend to act on, and every one of them fails often enough that the invalidation level matters more than the pattern.
Continuation patterns
These form inside an existing trend and describe a pause. The underlying story is always the same: the trend moved fast, some participants take profit, and the question is whether new participants absorb that supply.
| Pattern | Structure | What it says |
|---|---|---|
| Bull / bear flag | Sharp move, then a tight channel drifting against it | Profit-taking is orderly and being absorbed. The tighter and shorter the flag, the stronger the signal. |
| Pennant | Sharp move, then a small symmetrical triangle | Same as a flag, with both sides converging rather than drifting. |
| Ascending triangle | Flat top, rising lows | Supply sits at one price; buyers keep paying more to get to it. Usually resolves upward. |
| Descending triangle | Flat bottom, falling highs | The mirror. Demand sits at one price, sellers keep accepting less. |
| Symmetrical triangle | Both boundaries converging | Genuinely neutral. It signals a coming expansion in volatility, not a direction. |
| Rectangle / range | Horizontal top and bottom | Two clear levels and a fight between them. Trade the edges or the break. |
Symmetrical triangles are the most commonly misread pattern on this list. They are frequently described as bullish or bearish depending on the prior trend, but structurally they say only that the range is compressing. Direction is not encoded in the shape.
Reversal patterns
These describe a trend exhausting itself. They take longer to form than continuation patterns, and they require a real prior trend - a reversal pattern after sideways chop is just chop.
The main formations
Head and shoulders. Three peaks, the middle one highest, with a neckline connecting the lows between them. What it records is a trend making a higher high that fails to hold, then failing to reach the previous high at all. The pattern completes on the neckline break, not on the right shoulder.
Inverse head and shoulders. The same structure upside down, at the end of a downtrend.
Double top / double bottom. Two attempts at the same level, both rejected. Simple and common. Confirmation is the break of the low between the two peaks.
Triple top / bottom. Three attempts. More levels tested means more supply or demand confirmed at that price, so a break carries more weight when it comes.
Rounding top / bottom. A slow curved transition with no sharp turning point. Takes a long time and tends to appear on higher timeframes.
Rising / falling wedge. Both boundaries sloping the same way and converging. A rising wedge in an uptrend is usually read as weakening momentum, and it is one of the few patterns whose direction is encoded in the shape itself.
The rules that apply to all of them
A pattern is not complete until it breaks. A head and shoulders that never breaks the neckline is three bumps. Most losses attributed to "patterns failing" are actually from trading patterns that had not confirmed.
Every pattern has an invalidation level, and that is the useful part. The right shoulder high, the flag boundary, the triangle's opposite side. Knowing where the pattern is definitively wrong is more practically valuable than knowing what it predicts, because it is the only part that tells you anything about risk.
Size scales with formation time. A pattern that took three months to build generally implies a larger subsequent move than one that took three hours. The conventional measured-move targets are rough guides at best.
They are more obvious in hindsight. This is the honest caveat on every pattern guide including this one. Chart pattern examples are always selected after the fact. In real time, half-formed patterns look ambiguous, and many of the ones you identify will simply dissolve.
Why the same chart shows different patterns to different people
Pattern identification involves judgment about which highs and lows count as structurally significant. Two competent analysts can look at one chart and draw different triangles, because they made different decisions about which minor swing points to include.
That ambiguity is real and worth accepting rather than resolving. It is also a decent argument for getting an independent read - not because the second read is more correct, but because where two reads disagree is usually where the chart is genuinely ambiguous, and ambiguous charts are ones to size smaller in or skip.
Frequently asked questions
What is the most reliable chart pattern?
Head and shoulders and double tops or bottoms tend to be considered the most dependable reversal formations, mostly because they require the most confirmation - several tested levels and a decisive break. Among continuation patterns, tight flags following a strong move are generally regarded as the highest quality. That said, reliability varies enormously with market, timeframe and era, and published win rates should be treated as loose indications rather than facts.
How do I know if a chart pattern is complete?
It breaks its defining boundary and holds. A head and shoulders completes on the neckline break, a triangle on a close outside one of its converging lines, a double top on the break of the intervening low. Before the break it is a possible pattern, and possible patterns dissolve all the time.
What is the difference between continuation and reversal patterns?
Continuation patterns form inside a trend and describe a pause where one side absorbs profit-taking before the trend resumes. Reversal patterns form at the end of a trend and describe it running out of participants. Both require a prior trend to be meaningful, which is why either type appearing in a long sideways range is generally not worth much.
Can chart patterns be identified automatically?
Yes, and shape recognition is one of the things automated analysis handles well. Where judgment still matters is in deciding which swing points are structurally significant, which is genuinely ambiguous - it is why two analysts draw different triangles on the same chart. An automated read gives you a consistent answer, not the only possible answer.
