1

161.8% Extension

Fibonacci

The most important Fibonacci extension level in Elliott Wave analysis. Wave 3 frequently extends to exactly 161.8% of Wave 1. This level serves as both a target for Wave 3 and a confirmation that an extension is underway.

example

Wave 1 moves from 1.0800 to 1.0900 (100 pips). The 161.8% extension projects Wave 3 to reach 1.0962 from the end of Wave 2.

23.6% Retracement

Fibonacci

The shallowest common Fibonacci retracement level. When a correction only reaches the 23.6% level, it indicates extreme strength in the underlying trend. Rarely seen as the sole retracement target for Wave 2 or Wave 4.

Related:Fibonacci Retracement38.2% Retracement
3

38.2% Retracement

Fibonacci

A key Fibonacci retracement level and the most common target for Wave 4 corrections. When Wave 4 retraces exactly 38.2% of Wave 3, it suggests a strong trend that is likely to produce a dynamic Wave 5.

6

61.8% Retracement

Fibonacci

The 'golden retracement' level and the most common target for Wave 2 corrections. Derived from the golden ratio (1/1.618 = 0.618). When price reaches this level, it is often the deepest retracement before the next impulse wave begins.

Alternation

Concept

A guideline suggesting that if Wave 2 is a sharp correction, Wave 4 will likely be a sideways correction, and vice versa. This principle helps traders anticipate the type of correction to expect.

example

If Wave 2 was a sharp zigzag dropping 61.8%, Wave 4 might unfold as a flat or triangle.

B

Bear Market

Concept

In Elliott Wave context, a bear market represents the corrective phase (waves A-B-C) that follows a completed five-wave advance. The entire decline is labeled as a three-wave structure at the larger degree.

Related:Corrective WaveWave AWave BWave C

Bull Market

Concept

A five-wave impulse advance at a large degree. In Elliott Wave terms, the motive phase of the cycle where prices trend upward in five distinct waves before a corrective phase begins.

Related:Impulse WaveMotive Wave
C

Channeling

Concept

A technique where parallel trendlines are drawn connecting the ends of waves to project potential reversal zones. A channel drawn from the end of Wave 2 through Wave 4 often projects the terminus of Wave 5.

example

Draw a line from the end of Wave 1 to Wave 3, then a parallel line from Wave 2 — Wave 5 often terminates near this upper channel line.

Complex Correction

Corrective

A corrective pattern consisting of two or three simple corrective patterns joined by connecting waves labeled X. Examples include double zigzags (W-X-Y), double threes, and triple threes (W-X-Y-X-Z).

Related:Double ZigzagTriple ThreeWave X

Contracting Triangle

Corrective

A five-wave sideways pattern (A-B-C-D-E) where each successive wave is shorter than the previous one, forming converging trendlines. It typically appears in Wave 4 or Wave B position.

example

EURUSD forms a triangle in Wave 4 where Wave A is 80 pips, Wave B is 65 pips, Wave C is 50 pips, Wave D is 35 pips, and Wave E is 25 pips.

Related:TriangleWave 4Wave E

Corrective Wave

Corrective

A three-wave structure that moves against the trend of the next larger degree. Corrective waves are labeled A-B-C and include patterns like zigzags, flats, and triangles. They appear as Waves 2 and 4 within impulse sequences.

Related:ZigzagFlatTriangleWave 2Wave 4

Cycle Degree

Degree

One of the nine degrees of wave patterns identified by Elliott. Cycle degree waves typically span one to several years and are labeled with Roman numerals (I, II, III, IV, V).

Related:DegreeSupercyclePrimary Degree
D

Degree

Degree

The hierarchical classification of wave patterns by their relative size. Elliott identified nine degrees from Grand Supercycle (largest) to Subminuette (smallest). Each wave of one degree subdivides into waves of the next smaller degree.

Diagonal

Pattern

A motive pattern with overlapping waves that forms a wedge shape. Leading diagonals appear in Wave 1 or Wave A position; ending diagonals appear in Wave 5 or Wave C position. Both subdivide into five waves (3-3-3-3-3).

example

An ending diagonal in Wave 5 shows converging trendlines with each sub-wave being a three-wave structure, signaling the final exhaustion of the trend.

Related:Leading DiagonalEnding DiagonalWedge

Double Zigzag

Corrective

A complex corrective pattern consisting of two zigzag formations connected by a Wave X. Labeled W-X-Y, where both W and Y are zigzags. Typically produces a steeper correction than a single zigzag.

Related:ZigzagComplex CorrectionWave X
E

Elliott Wave Principle

Concept

The theory developed by Ralph Nelson Elliott in the 1930s that financial markets move in recognizable patterns reflecting the natural rhythm of crowd psychology. Markets advance in five waves and correct in three waves at all degrees of trend.

Related:Impulse WaveCorrective WaveFractalFibonacci

Ending Diagonal

Pattern

A wedge-shaped pattern appearing in the Wave 5 or Wave C position. It consists of five waves where each sub-wave subdivides into three (3-3-3-3-3). Both trendlines converge, and Wave 4 overlaps Wave 1 territory. It signals exhaustion of the larger trend.

example

XAUUSD forms an ending diagonal in Wave 5 where price squeezes between converging trendlines before a sharp reversal.

Related:DiagonalWave 5Wave CTruncation

Expanded Flat

Corrective

A corrective pattern where Wave B exceeds the start of Wave A, and Wave C extends well beyond the end of Wave A. The most common type of flat correction, often appearing in Wave 4 position. Structured as 3-3-5.

example

In a bullish trend, Wave A drops to 1.1000, Wave B rallies above the prior high to 1.1100, then Wave C plunges to 1.0900, extending beyond Wave A.

Related:FlatRegular FlatRunning Flat

Extension

Impulse

When one of the impulse waves (1, 3, or 5) subdivides into an elongated impulse with exaggerated subdivisions. Wave 3 extensions are most common in stock markets, while Wave 5 extensions are common in commodities. The extended wave is typically 161.8% or more of the next longest wave.

example

A Wave 3 extension in EURUSD runs 280 pips while Waves 1 and 5 are each approximately 100 pips.

Related:Wave 3Fibonacci Extension161.8%

Fibonacci Extension

Fibonacci

Price projections beyond 100% of a measured wave move. Common extension levels are 127.2%, 161.8%, 200%, and 261.8%. Used to project where Wave 3, Wave 5, or Wave C might terminate.

example

If Wave 1 travels 100 pips, the 161.8% extension projects Wave 3 to reach 161.8 pips from the start of Wave 1.

Fibonacci Retracement

Fibonacci

Price levels derived from the Fibonacci sequence where corrective waves are likely to find support or resistance. Key retracement levels are 23.6%, 38.2%, 50%, 61.8%, and 78.6%. Wave 2 commonly retraces 50%-61.8% of Wave 1.

example

After a 200-pip Wave 1 advance, Wave 2 pulls back to the 61.8% retracement level (124 pips) before Wave 3 begins.

Related:Fibonacci ExtensionGolden RatioWave 2

Flat

Corrective

A three-wave corrective pattern (A-B-C) where Wave A is three waves, Wave B retraces most or all of Wave A, and Wave C is five waves. Flats tend to be more sideways than zigzags. Three types exist: regular, expanded, and running.

Related:Expanded FlatRegular FlatRunning FlatCorrective Wave

Fractal

Concept

The self-similar nature of Elliott Wave patterns — each wave contains smaller versions of the same five-wave and three-wave structures. A Wave 3 on a daily chart, for example, subdivides into a complete five-wave impulse on the 4-hour chart.

Related:DegreeElliott Wave Principle
G

Golden Ratio

Fibonacci

The ratio 1.618 (phi), derived from the Fibonacci sequence. It is the mathematical foundation of Elliott Wave relationships. Wave 3 often equals 1.618 times Wave 1, and Wave 2 commonly retraces 61.8% (the inverse of 1.618) of Wave 1.

Grand Supercycle

Degree

The largest degree of wave pattern identified by Elliott, spanning several centuries. The current Grand Supercycle bull market is believed to have begun around 1784 in Western financial markets.

I

Impulse Wave

Impulse

A five-wave motive pattern (1-2-3-4-5) that moves in the direction of the trend at the next larger degree. Impulse waves have three strict rules: Wave 2 never retraces 100% of Wave 1, Wave 3 is never the shortest impulse wave, and Wave 4 never enters Wave 1 price territory.

example

A bullish impulse: Wave 1 rallies, Wave 2 corrects, Wave 3 surges (longest), Wave 4 consolidates, Wave 5 makes the final push higher.

Intermediate Degree

Degree

A wave degree typically lasting weeks to months. Labeled with parenthesized numbers (1), (2), (3), (4), (5) for motive waves and (A), (B), (C) for corrective waves.

Related:DegreePrimary DegreeMinor Degree

Invalidation Level

Rule

The price level at which a wave count is proven wrong. For example, if a Wave 4 count is proposed, the invalidation level is the peak of Wave 1 — because Wave 4 cannot overlap Wave 1 in an impulse. Professional analysts always mark invalidation levels on their charts.

example

A bullish Wave 3 count is invalidated if price drops below the start of Wave 1.

L

Leading Diagonal

Pattern

A wedge-shaped motive pattern appearing only in the Wave 1 or Wave A position. It consists of five overlapping waves (either 5-3-5-3-5 or 3-3-3-3-3). Leading diagonals signal the beginning of a new trend and are relatively rare.

M

Minor Degree

Degree

A wave degree typically lasting days to weeks. Labeled with Arabic numerals (1, 2, 3, 4, 5) and letters (a, b, c) without any additional notation.

Related:DegreeIntermediate DegreeMinute Degree

Minute Degree

Degree

A wave degree typically lasting hours to days. Labeled with circled Roman numerals for motive waves and circled lowercase letters for corrective waves.

Related:DegreeMinor DegreeMinuette Degree

Momentum Divergence

Concept

When price makes a new high (or low) but momentum indicators (RSI, MACD) do not confirm. In Elliott Wave analysis, divergence between Wave 3 and Wave 5 is extremely common and signals that Wave 5 is completing.

Related:Wave 5Truncation

Motive Wave

Impulse

Any wave pattern that propels prices in the direction of the next larger degree trend. Motive waves always subdivide into five sub-waves. The two types of motive patterns are impulse waves and diagonal waves.

Related:Impulse WaveDiagonal
P

Primary Degree

Degree

A wave degree typically lasting months to a few years. Labeled with circled numbers for motive waves and circled letters for corrective waves.

Related:DegreeCycle DegreeIntermediate Degree
R

Regular Flat

Corrective

A flat corrective pattern where Wave B retraces approximately 90-100% of Wave A, and Wave C is approximately equal in length to Wave A. The rarest type of flat correction.

Related:FlatExpanded FlatRunning Flat

Running Flat

Corrective

A rare flat correction where Wave B exceeds the start of Wave A (like an expanded flat), but Wave C fails to reach the end of Wave A. This indicates extreme strength in the direction of the larger trend.

Related:FlatExpanded FlatRegular Flat

Running Triangle

Corrective

A triangle where Wave B exceeds the start of Wave A. This is a strong continuation pattern that indicates the trend will resume with force after the triangle completes.

S

Subminuette Degree

Degree

The smallest wave degree commonly tracked, typically lasting minutes to hours. Used primarily in intraday trading analysis.

Related:DegreeMinuette Degree

Supercycle Degree

Degree

A wave degree spanning multiple decades (typically 40-70 years). Labeled with parenthesized Roman numerals (I), (II), (III), (IV), (V).

Related:DegreeGrand SupercycleCycle Degree
T

Triangle

Corrective

A five-wave sideways corrective pattern labeled A-B-C-D-E. Triangles form converging (contracting), diverging (expanding), or running patterns. They appear exclusively in Wave 4 or Wave B position and always precede the final wave of the larger pattern.

example

A contracting triangle in Wave 4: each swing (A through E) gets progressively smaller, and the breakout from Wave E launches the final Wave 5.

Related:Contracting TriangleRunning TriangleWave 4Wave E

Triple Three

Corrective

The most complex corrective pattern, consisting of three simple corrections connected by two X waves: W-X-Y-X-Z. Each component (W, Y, Z) can be any corrective pattern except a triangle (only Z can be a triangle). Rare in practice.

Related:Complex CorrectionDouble ThreeWave X

Truncation

Impulse

When Wave 5 fails to exceed the end of Wave 3. Truncations occur after an extremely powerful Wave 3. The Wave 5 'truncates' — it subdivides into five waves but falls short of making a new high (or low). This signals exceptional weakness (or strength in a bear market).

example

After a massive Wave 3 rally of 500 pips, Wave 5 only manages 20 pips beyond Wave 3, barely making a new high before a major reversal.

Related:Wave 5Wave 3Ending Diagonal
W

Wave 1

Impulse

The first impulse wave in a five-wave sequence. Wave 1 is often the hardest to identify in real-time because it emerges from the end of a prior correction. It subdivides into five smaller waves and establishes the new trend direction.

Related:Impulse WaveWave 2Leading Diagonal

Wave 2

Impulse

The first corrective wave in an impulse sequence. Wave 2 retraces a portion of Wave 1 but never retraces beyond its starting point. Common retracements are 50%-61.8% of Wave 1. Wave 2 corrections tend to be sharp (zigzags).

Related:Wave 1Fibonacci RetracementAlternation

Wave 2 Rule

Rule

An absolute rule stating that Wave 2 can never retrace more than 100% of Wave 1. If price moves beyond the starting point of Wave 1, the wave count is invalidated. This is one of the three inviolable rules of Elliott Wave analysis.

Related:Wave 1Wave 2Invalidation Level

Wave 3

Impulse

Usually the longest and most powerful impulse wave. Wave 3 is never the shortest of waves 1, 3, and 5. It commonly extends to 161.8% of Wave 1 and often features the strongest momentum, highest volume, and widest price bars. This is where professional traders aim to capture the largest moves.

example

In EURUSD, Wave 1 moves 100 pips, Wave 2 retraces 62 pips, then Wave 3 surges 162 pips (161.8% of Wave 1).

Related:ExtensionFibonacci Extension161.8%

Wave 3 Rule

Rule

An absolute rule stating that Wave 3 can never be the shortest of the three impulse waves (1, 3, and 5). Note: Wave 3 does not need to be the longest — it simply cannot be the shortest. If it appears shorter than both waves 1 and 5, the count is wrong.

Related:Wave 3Impulse WaveExtension

Wave 4

Impulse

The second corrective wave within an impulse sequence. Wave 4 never overlaps with Wave 1 price territory (strict rule). It commonly retraces 38.2% of Wave 3. Wave 4 corrections tend to be sideways (flats and triangles), alternating with Wave 2.

Related:Wave 1AlternationTriangleFlat

Wave 4 Rule

Rule

An absolute rule stating that in an impulse wave, Wave 4 cannot enter the price territory of Wave 1. The low of Wave 4 must remain above the high of Wave 1 in a bull market (and vice versa in a bear market). The only exception is in diagonal patterns.

Related:Wave 4Wave 1DiagonalInvalidation Level

Wave 5

Impulse

The final impulse wave in the motive sequence. Wave 5 completes the trend and is often equal in length to Wave 1 or reaches 61.8% of the net distance from Wave 1 through Wave 3. It typically shows momentum divergence and lower volume than Wave 3, signaling trend exhaustion.

Related:TruncationEnding DiagonalMomentum Divergence

Wave A

Corrective

The first wave of a corrective sequence (A-B-C). Wave A establishes the corrective trend direction. It can subdivide into either five waves (in a zigzag) or three waves (in a flat). Identifying Wave A correctly is crucial for anticipating the rest of the correction.

Related:Corrective WaveWave BWave CZigzagFlat

Wave B

Corrective

The second wave of a corrective sequence. Wave B moves against the corrective trend direction, often trapping traders who mistake it for a trend resumption. In expanded flats, Wave B exceeds the start of Wave A. Wave B always subdivides into three waves.

Related:Wave AWave CExpanded FlatBull Trap

Wave C

Corrective

The final wave of a corrective sequence. Wave C always subdivides into five waves and often equals Wave A in length or extends to 161.8% of Wave A. Wave C completes the correction and typically represents the most dynamically powerful part of the corrective phase.

Related:Wave AWave BFibonacci Extension

Wave Count

Concept

The labeling of price movements according to Elliott Wave patterns. A wave count identifies which wave the market is currently in and projects future price movements. Professional analysts maintain multiple wave counts ranked by probability.

Related:Elliott Wave PrincipleDegreeInvalidation Level

Wave E

Corrective

The fifth and final wave of a triangle pattern. Wave E often falls short of the trendline drawn from waves A and C, creating a 'throw-under.' The completion of Wave E signals an imminent breakout in the direction of the larger trend.

Related:TriangleContracting Triangle

Wave Equality

Rule

A guideline stating that two of the three impulse waves (1, 3, 5) tend to be equal in price magnitude. When Wave 3 extends, waves 1 and 5 tend toward equality. Useful for projecting the length of Wave 5.

Related:Wave 1Wave 5Fibonacci Extension

Wave X

Corrective

A connecting corrective wave that joins two simple corrections in a complex pattern. Wave X is typically a brief, shallow correction (often a zigzag). In W-X-Y patterns, Wave X connects the first correction (W) to the second (Y).

Related:Complex CorrectionDouble ZigzagTriple Three
Z

Zigzag

Corrective

A sharp three-wave corrective pattern labeled A-B-C where Wave A and Wave C are impulse waves (five sub-waves each) and Wave B is a corrective wave (three sub-waves). Zigzags are structured as 5-3-5 and typically retrace 50%-61.8% of the prior impulse wave.

example

After a 300-pip rally, a zigzag correction unfolds: Wave A drops 120 pips in five waves, Wave B bounces 50 pips in three waves, then Wave C drops another 100 pips in five waves.

Frequently Asked Questions

What are the three rules of Elliott Wave?

The three inviolable rules are: (1) Wave 2 never retraces more than 100% of Wave 1, (2) Wave 3 is never the shortest impulse wave, and (3) Wave 4 never enters Wave 1 price territory in an impulse pattern.

What is the most important Fibonacci level in Elliott Wave?

The 61.8% retracement (golden ratio) is the most important level. Wave 2 commonly retraces 61.8% of Wave 1, and Wave 3 often extends to 161.8% of Wave 1.

What is the difference between impulse and corrective waves?

Impulse waves move in the direction of the larger trend and consist of five sub-waves (1-2-3-4-5). Corrective waves move against the trend and consist of three sub-waves (A-B-C). Impulse waves are labeled with numbers, corrective waves with letters.

How many degrees of waves are there in Elliott Wave Theory?

Elliott identified nine degrees of waves: Grand Supercycle (centuries), Supercycle (decades), Cycle (years), Primary (months-years), Intermediate (weeks-months), Minor (days-weeks), Minute (hours-days), Minuette (hours), and Subminuette (minutes).

What is a truncation in Elliott Wave?

A truncation occurs when Wave 5 fails to exceed the high of Wave 3 (in a bull market). It signals extreme weakness and typically happens after an exceptionally powerful Wave 3. Truncations are followed by sharp reversals.
