1. Diametric Formation {#nw_diametric_formation}

The Diametric Formation is a unique 7-wave pattern discovered within NEoWave that describes a complex corrective structure unexplainable by traditional Elliott Wave Theory. Elliott classified corrective patterns into triangles (5 waves), flats (3 waves), zigzags (3 waves), and similar categories, yet real markets repeatedly produce 7-wave corrections that fit none of these classifications neatly. Glenn Neely systematized this phenomenon and established it as a new pattern called the Diametric Formation.

The name "Diametric" derives from the geometric relationship in which the pattern's starting point (beginning of wave-A) and ending point (end of wave-G) occupy diametrically opposite positions.

Structural Characteristics

• 7 Segments: Composed of a 7-wave structure labeled A-B-C-D-E-F-G
• Bow-Tie Shape: The first half (A→D) converges toward the center (wave-D), while the second half (D→G) expands outward, creating a distinctive bow-tie configuration
• Symmetry: The first and second halves mirror each other around wave-D, with A↔G, B↔F, and C↔E forming symmetric pairs
• Time Relationships: Each wave's duration is relatively proportional, with wave-D serving as the temporal center axis
• Alternation Principle: Adjacent waves alternate between simple↔complex and short↔long characteristics

Detailed Wave Behavior

• Wave-A: Initiates the correction, typically taking a simple zigzag or flat form. It establishes the reference points (price and time) for the entire pattern.
• Wave-B: Retraces 38.2%–61.8% of wave-A, with a duration similar to wave-A. Its structure is relatively simple.
• Wave-C: The most complex and time-consuming wave in the first half. Double zigzags and triple zigzags appear frequently, requiring the most careful internal structure analysis.
• Wave-D: The central axis of the pattern, occurring at the narrowest price range. It marks the inflection point where convergence transitions to expansion and serves as the key confirmation clue for a Diametric.
• Wave-E: Occupies a symmetric position to wave-C but exhibits a simpler structure. It signals the beginning of the expansion phase.
• Wave-F: Revisits the wave-D price level and forms a temporal symmetry with wave-B.
• Wave-G: Completes the final correction, terminating at a position diametrically symmetric to wave-A.

Identification Criteria

• Wave-C retraces at least 61.8% of wave-A
• Wave-E does not exceed the extreme (high/low) of wave-C
• Wave-G terminates within the price range of wave-E
• Wave-D is positioned at the temporal midpoint of the pattern
• The entire pattern consists of exactly 7 waves with no further subdivision possible
• The bow-tie shape is visually confirmable

Validation Rules

Wave	Price Relationship	Time Relationship	Structural Feature
A	Sets reference point	Reference duration	Simple correction
B	38.2%–78.6% of A	Similar to A	Simple structure
C	Exceeds A by 61.8%+	Longest duration	Most complex
D	61.8%–78.6% of C	Pattern midpoint	Convergence point
E	Does not reach C extreme	Shorter than C	Simpler than C
F	Revisits D level	Symmetric with B	Simple structure
G	Terminates within E range	Symmetric with A	Final correction

Practical Application

• Identification Phase: First assess wave-C's complexity and time consumption. If a 7-wave correction is suspected, observe whether wave-D converges after A-B-C completion.
• Progress Tracking: Confirm whether price range narrows at wave-D. If wave-D forms within a tight price band, the probability of a Diametric increases significantly.
• Completion Confirmation: Verify that wave-G does not exceed the wave-E range. If wave-G breaches the wave-E range, the pattern must be reassessed.
• Breakout Preparation: After wave-G completion, anticipate a powerful impulse move and prepare for entry. Post-Diametric breakouts characteristically display strong directionality and rapid velocity.

Practical Tip: In cryptocurrency markets, Diametric Formations frequently appear during deep corrections between major impulse waves. Because volatility is greater than in traditional markets, the retracement ratios of waves B, D, and F often approach the upper bound (78.6%). Monitoring Bollinger Band width changes during pattern formation helps identify the wave-D convergence point more precisely.

Market Environment and Occurrence Patterns

• Bull Markets: Diametrics form during deep corrections following major rallies. In this case, an upward impulse is likely to resume after wave-G completion.
• Bear Markets: Inverse Diametrics form during corrective bounces after major declines. Additional downside may follow wave-G completion, requiring caution.
• Sideways Markets: Diametrics appear as complex corrective patterns within prolonged trading ranges and can be used as precursors to range breakouts.

Distinguishing from Other Patterns

Diametrics are easily confused with the following patterns and require careful differentiation:

• Double/Triple Combinations: Combinations are also complex corrections but include X-waves (connecting waves) and lack bow-tie symmetry.
• Expanding Triangles: These are 5-wave structures, not 7-wave. Accurate wave counting resolves the distinction.
• Symmetrical Diametric: The symmetrical variant displays a diamond shape rather than a bow-tie, with wave-D being the widest point (expansion peak).

2. Neutral Triangle {#nw_neutral_triangle}

The Neutral Triangle is a redefined triangle pattern within NEoWave that further subdivides the traditional Elliott Wave Contracting Triangle into a more precise concept. Neely describes this pattern as serving as the "missing link" connecting the impulse world and the triangle world. It applies stricter rules than traditional triangles and represents a highly refined pattern.

The "Neutral" designation reflects the fact that this triangle represents a neutral energy state—neither bullish nor bearish—with no directional bias prior to the breakout. However, breakouts statistically tend to occur in the direction of the preceding trend.

Wave Structure Characteristics

• 5-Wave Structure: Composed of A-B-C-D-E segments
• Converging Form: Upper and lower trendlines progressively converge
• Wave-C Dominance: Wave-C is the longest, most complex, and most time-consuming wave—this is the key identification clue for a Neutral Triangle
• Time Balance: Waves A, B, D, and E have relatively similar durations

Detailed Wave Analysis

• Wave-A: The initiating wave of the triangle, typically taking a zigzag or flat structure. It forms the first touch point on the upper (or lower) boundary line.
• Wave-B: Retraces 61.8%–78.6% of wave-A with a relatively simple structure. It forms the first touch point on the opposite boundary line.
• Wave-C: The core of the pattern—most complex and longest in duration. Double/triple zigzags appear frequently, and its time consumption constitutes a substantial proportion even when compared to the combined duration of the other four waves.
• Wave-D: Retraces 61.8%–78.6% of wave-C with a structure simpler than wave-B. Amplitude decreases as convergence progresses.
• Wave-E: Terminates near the wave-D endpoint and is the shortest, simplest wave. The rapid completion of wave-E signals an imminent breakout.

Practical Application Rules

• Wave-B retraces at least 50% of wave-A (minimum condition)
• Wave-C extends beyond the wave-B endpoint but does not exceed the wave-A endpoint
• Wave-D retraces at least 50% of wave-C
• Wave-E slightly exceeds or falls short of the wave-D endpoint
• Amplitude of each successive wave progressively decreases
• All internal waves are composed of corrective structures (3-wave)

Validation Checklist

• Is wave-C the most complex structure in the entire pattern?
• Is wave-C's duration significantly longer than other waves?
• Do the upper and lower boundary lines clearly converge?
• Does wave-E terminate within the triangle boundaries?
• Does the entire pattern serve as a correction to the preceding trend?
• Does amplitude decrease sequentially across waves?

Trading Strategy

Phase	Entry/Exit Signal	Risk Management
A-B in progress	Observation phase	No position
Wave-C in progress	Consider short (or long) position anticipating C extension	Stop-loss above wave-C high
D-E in progress	Prepare breakout-direction position anticipating wave-E completion	Stop-loss below wave-D low
Post-breakout	Set target equal to triangle height (wave-A amplitude)	Stop-loss if price re-enters triangle interior

Practical Tip: The first throw-back after a triangle breakout can reach the vicinity of the triangle apex. Using this throw-back as a secondary entry opportunity improves the risk-reward ratio. However, if the throw-back penetrates deeply back into the triangle interior, treat it as a pattern failure.

Time Analysis Points

• Wave-C duration accounts for over 50% of the combined A+B+D+E duration
• Total pattern duration equals 61.8%–100% of the preceding impulse
• Time to wave-E completion tends to align with Fibonacci time sequences
• The triangle apex timing provides a clue for breakout timing

Distinguishing from Other Triangles

• Ascending/Descending Triangles: One boundary is horizontal, whereas both boundaries are sloped in a Neutral Triangle.
• Running Triangle: Wave-B exceeds the wave-A starting point—this overshoot does not occur in Neutral Triangles.
• Expanding Triangle (Extracting): Amplitude progressively increases—the opposite directional pattern.

3. Extracting Triangle {#nw_extracting_triangle}

The Extracting Triangle is an expanding triangle pattern that represents the structural opposite of the contracting triangle. While adhering to fundamental triangle rules, it exhibits a unique form in which alternation is reversed. In some cases, one direction contracts while the opposite direction expands simultaneously.

This pattern forms during periods of increasing market uncertainty. As participant opinions polarize, each wave's amplitude progressively increases and volatility expands. While its external appearance resembles what traditional technical analysis calls the "Megaphone Pattern" or "Broadening Formation," NEoWave differentiates itself by rigorously analyzing internal wave structure.

Pattern Characteristics

• Expanding Structure: Upper and lower trendlines progressively diverge (opposite of contracting triangles)
• Increasing Volatility: Each wave's amplitude progressively expands
• Alternation Reversal: The typical simple↔complex alternation becomes inverted
• Instability: Appears in environments of high market uncertainty
• Rarity: Lower occurrence frequency compared to contracting triangles, making identification experience critical

Structural Analysis

• Wave-A: A relatively simple initiating wave that establishes the baseline amplitude for subsequent expansion.
• Wave-B: More complex with a larger retracement than wave-A (78.6%+ possible). May exceed wave-A's starting point.
• Wave-C: An even more extended move than wave-B, with significantly larger amplitude. Internal structural complexity also increases.
• Wave-D: Exhibits a larger retracement and greater complexity than wave-C, touching the opposite trendline at a more distant point.
• Wave-E: The final wave exhibiting the most extreme movement in the entire pattern. A sharp reversal follows wave-E completion.

Identification Criteria

• Each successive wave has a larger amplitude than the previous wave
• A minimum of 3 touch points are required on each trendline
• Wave-E records the largest price swing of the entire pattern
• The divergence angle of the boundary lines progressively increases
• All internal waves are composed of corrective structures (3-wave)
• The entire pattern occupies a corrective position relative to the preceding trend

Validation Rules

Element	Criterion	Verification Method
Amplitude expansion	Each wave > previous wave	Measure high-low range
Time increase	Progressive increase in wave duration	Time ratio analysis
Complexity increase	Progressive internal complexity	Sub-wave counting
Divergence angle	Continuous expansion	Trendline angle measurement
Internal structure	All waves are 3-wave corrections	Confirm impulse structure exclusion

Practical Trading Strategy

1. Pattern Recognition: After initial A-B-C confirmation, observe whether expansion is occurring. If wave-B's amplitude exceeds wave-A's, consider the expanding triangle possibility.
2. Entry Timing: Prepare to enter in the wave-E direction after wave-D completion. Wave-E exhibits the largest amplitude, offering the highest profit potential.
3. Risk Management: Due to the expanding nature, each wave's extreme exceeds the previous one, requiring wider stop-loss levels. Tight stops will result in premature exits.
4. Profit Taking: Since a sharp reversal follows wave-E completion, execute scaled exits at Fibonacci extension levels of wave-E (161.8%, 200%).

Caution: Because Extracting Triangles form during periods of expanding volatility, it is safer to reduce leverage below normal levels. In cryptocurrency markets, wave-E spikes can become more extreme than expected when combined with liquidation cascades.

Market Psychology

• Maximized Fear and Greed: Emotions amplify with each wave, producing repeated extreme buying/selling crowding.
• Volatility Expansion: Uncertainty progressively increases, driving options implied volatility (IV) higher as well.
• Crowd Psychology: Extreme position crowding appears at each wave's extreme, with forced liquidations amplifying rebounds and selloffs.
• Reversal Signal: A powerful trend reversal occurs after wave-E completion, signaling that market participant energy has been fully exhausted.

Complementary Indicators for Expanding Triangles

• Bollinger Bands: Band width expansion synchronizes with pattern progression.
• ATR (Average True Range): Increasing ATR per wave numerically confirms the expanding structure.
• RSI: Entries into overbought/oversold territory at each wave's extreme become progressively more extreme.

4. 3rd Extension Terminal {#nw_3rd_ext_terminal}

The 3rd Extension Terminal is a 5-wave terminal pattern in which wave-3 is the largest wave (extension), and overlap between waves 2 and 4 is permitted. The defining characteristic is that all internal structures are corrective, which is the critical distinction from a standard impulse.

The name "Terminal" was given because this pattern tends to appear at the "terminal point" (end) of a larger wave. While similar to the traditional Elliott Wave "Ending Diagonal," NEoWave applies more refined rules. Because a sharp and rapid reversal follows terminal completion, it serves as an extremely important reversal signal in practice.

Structural Conditions

• Wave-3 Dominance: Wave-3 is significantly larger than waves 1 and 5 (the extended wave)
• Wave-5 Weakness: Wave-5 is relatively short and weak compared to wave-3
• Terminal Shape: Connecting the extremes of waves 1-3-5 produces a converging diagonal (wedge) shape
• Internal Structure: All waves (1, 2, 3, 4, 5) are composed exclusively of corrective structures (3-wave)
• Overlap Permitted: Price ranges of waves 2 and 4 may overlap (prohibited in standard impulses)

Wave-by-Wave Analysis

• Wave-1: Composed of a 3-wave corrective structure and is relatively simple. It forms the starting point of the terminal and the first reference point of the converging trendline.
• Wave-2: Retraces 50%–78.6% of wave-1, taking a flat or zigzag form.
• Wave-3: The longest and most complex extended wave, typically composed of 9–13 sub-waves. It consumes the most time and price distance of any wave in the pattern.
• Wave-4: May overlap with the wave-2 price range and exhibits a simpler structure than wave-3. The alternation principle applies between waves 2 and 4.
• Wave-5: Slightly exceeds the wave-3 high (bullish terminal) or low (bearish terminal) but is relatively weak. Truncation may occur.

Practical Identification

Element	Condition	Verification Indicator
Wave-3 length	162%+ of wave-1	Price ratio measurement
Wave-5 length	61.8% or less of wave-3	Relative size comparison
Time relationship	Wave-3 accounts for 50%+ of total pattern time	Time ratio analysis
Internal structure	All waves are 3-wave corrections	Sub-wave counting
Overlap	Waves 2 and 4 price ranges overlap	Price range comparison
Converging shape	Lines connecting 1-3-5 extremes converge	Trendline plotting

Momentum Analysis

• Wave-1: Initial momentum formation, RSI in the 30–70 range
• Wave-2: Momentum decline, RSI approaching oversold
• Wave-3: Strongest momentum phase, RSI sustained at 70–90 (for bullish terminals)
• Wave-4: Momentum deceleration, RSI declining
• Wave-5: Momentum divergence occurs—RSI fails to exceed wave-3's peak — this is the most powerful confirmation signal of terminal completion

Volume Pattern

• Wave-1: Normal volume levels
• Wave-2: Volume decrease
• Wave-3: Maximum volume (150–200% of average), with persistently high volume throughout the extension phase
• Wave-4: Volume decline
• Wave-5: Volume decrease (price vs. volume divergence) — rising prices accompanied by declining volume signals imminent terminal completion

Post-Completion Behavior

• Sharp Reversal: A powerful counter-directional move occurs immediately after terminal completion. The speed and intensity of this reversal are significantly greater than with standard patterns.
• Retracement Depth: Typically retraces 78.6%–100% of the entire terminal length rapidly.
• Speed: The retracement completes within 1/3 to 1/2 of the time taken to form the terminal.
• Practical Application: Upon confirming wave-5 completion, immediately take a counter-directional position with a stop-loss set just beyond the wave-5 extreme.

Practical Tip: In cryptocurrency markets, 3rd Extension Terminals frequently appear during the final phase of major rallies. When identified on Bitcoin's weekly or daily charts at the terminus of a long-term uptrend, the subsequent sharp correction (78.6%–100% retracement) makes this a decisive timing signal for position liquidation.

5. 5th Failure Terminal {#nw_5th_failure_terminal}

The 5th Failure Terminal is externally similar to a 3rd Extension Impulse but is distinguished by wave 2 and 4 price overlap and exclusively corrective internal structures. The defining feature of this pattern is that wave-5 fails to exceed wave-3's extreme, signaling one of the most powerful reversal indicators—complete exhaustion of trend energy.

Core Conditions

• Wave-5 Failure: Wave-5 fails to exceed wave-3's extreme (high in uptrends, low in downtrends)
• Momentum Weakness: Price progression diminishes markedly, with clear indicator divergence
• Counter-Trend Signal: Implies a powerful trend reversal
• Internal Structure: All waves are corrective (3-wave) in character
• Overlap Permitted: Wave 2 and wave 4 price ranges may overlap

Structural Differences (vs. 3rd Extension Impulse)

Feature	3rd Ext Impulse	5th Failure Terminal
Wave-5 achievement	Exceeds wave-3 high	Fails to reach wave-3 high
Internal structure	Waves 1, 3, 5 are impulsive	All waves are corrective
Wave 2, 4 relationship	No overlap	Overlap permitted
Wave-5 momentum	Weak but reaches target	Pronounced divergence
Reversal intensity	Standard reversal	Very strong and rapid reversal
Occurrence location	Mid to late trend	Final phase of trend

Wave-5 Failure Confirmation Factors

• Volume decreases significantly in wave-5 (50% or less of wave-3 levels)
• Clear divergence appears on momentum indicators such as RSI or MACD
• Wave-5 length is 38.2% or less of the average wave length
• Wave-5 reverses precisely at a Fibonacci retracement level (38.2%, 50%, 61.8%)
• Energy exhaustion signs appear within wave-5 (shrinking candle bodies, increasing upper/lower wicks)

Fibonacci Target Analysis

The intensity of the subsequent reversal can be estimated based on the degree to which wave-5 "fails" to reach wave-3's extreme.

• 38.2% Failure (wave-5 reverses at the 38.2% level of wave-3): The weakest failure, with potential for a renewed attempt. Cautious position management is required.
• 50% Failure (wave-5 reverses at the 50% level of wave-3): A moderate-strength failure, applicable as a medium-term reversal signal.
• 61.8% Failure (wave-5 reverses at the 61.8% level of wave-3): A strong failure signal forecasting a long-term trend reversal. This level of failure carries the highest reliability.

Validation Methodology

1. Wave Counting: Confirm that all internal waves are 3-wave corrective structures. If even one decomposes into a 5-wave impulse, the pattern is not a terminal.
2. Momentum Analysis: Verify the presence of RSI/MACD divergence in wave-5.
3. Volume Confirmation: Validate that wave-5 volume has decreased significantly relative to wave-3.
4. Time Relationship: Confirm that wave-5 duration is shorter than wave-3 and accounts for a smaller proportion of total pattern time.
5. Fibonacci Validation: Confirm that wave-5 reversed at a precise retracement level (38.2%, 50%, 61.8%).

Practical Trading Approach

• Entry: Take a counter-directional position after confirming wave-5 failure. A reversal candle forming before wave-5 reaches wave-3's extreme constitutes the entry signal.
• Stop-Loss: Exit immediately if wave-5 breaks through wave-3's high/low (failure invalidation). The pattern may be transitioning to a standard extension rather than a failure.
• Target: Set the first target at a full retracement to the terminal starting point and the second target at the 61.8% retracement level.
• Time: A rapid reversal is expected, making short-term concentrated strategies appropriate. The target is frequently reached within half the terminal formation time.

Caution: Prematurely concluding a wave-5 failure risks taking a counter-directional position against a wave-5 still in progress. Always wait until at least three confirmation conditions are simultaneously met: divergence + declining volume + Fibonacci level reversal.

6. Supplemental Price & Time Action {#nw_supplemental_price_time}

Supplemental Price & Time Action is a unique phenomenon that can occur in all terminals and triangles, where the market slightly exceeds the optimal price/time zone before reversing and proceeding as originally expected—a trader trap. Without understanding this concept, even correct pattern analysis will result in losses from false breakouts.

Nature of the Phenomenon

• Time Overshoot: Pattern completion extends slightly beyond the expected timing (e.g., exceeding the Fibonacci time target by 5–10%)
• Price Breach: Price temporarily breaks through pattern boundaries (triangle trendlines, terminal channels, etc.)
• Immediate Reversal: After the breach, price promptly returns to the direction originally forecast by the pattern
• Trap Function: Lures premature breakout trades into losses, and the liquidation of those losing positions then becomes fuel for the correct directional trend

Occurrence Mechanism

1. Pattern Near Completion: The terminal/triangle reaches its near-completion stage
2. Market Expectation Formation: Most participants anticipate the pattern's completion and direction
3. Final Wave Extension: The last wave extends slightly beyond expectations, betraying the consensus
4. False Breakout: Price temporarily breaches pattern boundaries, triggering breakout traders to enter
5. Rapid Reversal: A powerful move begins in the originally expected direction, accelerated by the liquidation of positions that entered on the false breakout

Time Relationship Analysis

• Fibonacci Time: Pattern completion time typically overshoots Fibonacci ratios by 5–8%
• Equal Time: Wave duration estimates may deviate by 10–15%
• Acceleration/Deceleration: Time flow in the final wave differs from expectations, usually progressing slower than anticipated before reversing sharply

Price-Time Combination Rules

• Pattern reliability is highest when both price and time satisfy Fibonacci ratios
• When time analysis conflicts with price analysis, the pattern requires reassessment
• In terminals and triangles, time relationships are as important as price relationships
• If price returns to the originally expected direction after supplemental action, it should be interpreted as a confirmation signal that actually increases pattern reliability

Practical Response Strategy

Situation	Response	Risk Management
Time overshoot	Maintain patience, avoid premature entry	Pre-set pattern invalidation levels
Price breach	Treat as false breakout, prepare counter-entry	Stop-loss if breach extends (3–5% beyond boundary)
Reversal confirmation	Enter immediately in the original direction	Stop-loss if price re-breaches the boundary
Trend continuation	Follow the strong impulse	Partial exit on retracement within pattern range

Practical Tip: Supplemental action frequently occurs during weekends and low-liquidity hours in cryptocurrency markets. Price temporarily breaches pattern boundaries during thin trading periods, then strongly reverts to the expected direction during major trading sessions. Therefore, treat breakouts during low-liquidity periods with skepticism and wait for confirmation during primary trading hours.

Psychological Factors

• Impatience: The urge to enter prematurely in anticipation of pattern completion
• Confirmation Bias: Excessive conviction in a clear pattern, leading to delayed stop-loss execution
• FOMO (Fear of Missing Out): Chasing a breakout without confirmation, fearing a missed opportunity
• Revenge Trading: Taking an oversized position in the opposite direction out of emotion after a false breakout loss

Verification Points

• Does the supplemental action occur within 3–5% of the pattern boundary? (If it exceeds 5%, reassess the pattern itself)
• Is the time overshoot within 10% of the expected duration? (If it exceeds 10%, reanalyze time relationships)
• Does the post-reversal move cover 61.8%+ of the pattern's size? (If less, it may not be supplemental action)
• Does volume surge at the reversal point? (Confirms liquidation of false breakout positions)

7. Expanding Triangle Spike Behavior {#nw_expanding_triangle_spike}

Sharp spikes tend to occur at each wave's extreme within expanding triangles, and this behavioral pattern alone can serve as an important signal for detecting an expanding triangle environment. Spikes occur at the moment each wave newly exceeds the previous wave's extreme, directly linked to the expanding triangle's characteristic volatility increase.

Spike Characteristics

• Rapid Movement: Price rapidly breaks through pattern boundary lines (trendlines), producing large price changes in short timeframes
• High Volume: Volume surges to 150%+ of average during the breakout
• Momentum Persistence: Price continues in the same direction for an additional distance after the spike
• Repetition: Spikes of similar intensity recur at each wave's extreme, with spike intensity progressively increasing as waves advance

Spike Formation Mechanism

1. Pressure Accumulation: Buy/sell energy accumulates within the expanding triangle
2. Extreme Approach: As each wave approaches the previous extreme, pending orders and stop-loss orders cluster
3. Breakout Trigger: Clustered orders execute simultaneously, initiating a powerful breakout
4. Rapid Acceleration: At the breakout moment, stop-loss cascades and chase buying/selling compound to produce accelerating price movement
5. Momentum Persistence: Directionality is maintained after the spike, forming that wave's extreme

Wave-by-Wave Spike Pattern

• Wave-A Extreme: The initial spike is relatively moderate. As the expanding triangle is still in its early formation, market participant attention remains limited.
• Wave-B Extreme: A stronger spike than wave-A occurs, with a sharp retracement as well. Counter-directional traders' stop-losses are triggered.
• Wave-C Extreme: Maximum-intensity spike appears, marking the core phase of expansion acceleration. Market attention begins to concentrate.
• Wave-D Extreme: A spike similar to or stronger than wave-C's, creating psychological pressure on traders in both directions.
• Wave-E Extreme: The final spike, followed by a powerful reversal after pattern completion. This spike is the most extreme across the entire expanding triangle.

Practical Application

• Monitor the spike direction after wave-E completion. The direction opposite to the wave-E spike is the subsequent trend direction.
• Reliability is high when spike size reaches 61.8% or more of the triangle height (widest point).
• Filter false breakouts through volume confirmation. Breakouts without volume surges have a high probability of being false.
• Execute immediate trend-following strategies on spike occurrence, but also establish position-switching plans in anticipation of the final reversal after wave-E.

Volume Analysis

Spike Phase	Volume Characteristics	Verification Method
Pressure accumulation	Gradual volume increase	120–140% of 20-day average
Breakout moment	Volume surge	200%+ of average
Acceleration phase	Sustained high volume	Maintained at 150%+ of average
Stabilization	Volume normalization	Returns to average levels

Timeframe Application

• Daily: Spikes last 1–3 days and provide the strongest reliability. Suitable for swing trading.
• 4-Hour: Spikes last 4–12 hours and are useful for medium-term directional assessment.
• 1-Hour: Spikes last 1–4 hours and serve as day trading entry/exit signals.
• 15-Minute: Spikes last 15 minutes to 1 hour and can be used as scalping opportunities. However, distinguishing from noise is difficult and requires experience.

Practical Tip: In cryptocurrency markets, expanding triangle spikes become extreme when combined with high-leverage position liquidation cascades. Referencing liquidation heatmap data allows for more accurate prediction of spike intensity and direction.

Risk Management

• Entry: Enter immediately after confirming spike direction (follow spike direction for waves before wave-E; enter reversal direction after wave-E completion)
• Stop-Loss: Exit immediately if price re-enters the triangle boundary (or exceeds wave-E's extreme)
• Target: Set the first profit target equal to the triangle height (amplitude at the widest point)
• Scaled Exits: Close 50% at the first target; manage the remaining position with a trailing stop

Trading Strategy Example

1. Pattern Recognition: Detect that an expanding triangle is forming (increasing amplitude + diverging trendlines)
2. Spike Anticipation: After wave-E completion, monitor the direction and intensity of the final spike
3. Confirmation Signal: Confirm the spike breakout accompanied by a volume surge
4. Entry Execution: Establish a position in the wave-E reversal direction (opposite to the wave-E spike direction)
5. Management: Take profit at the triangle height target and consider additional entry on intermediate retracements

8. Common Impulsion Behavior Mistakes {#nw_impulsion_behavior_mistakes}

These are frequently occurring impulse pattern identification errors in NEoWave analysis and methods to prevent them. The three most common behavioral errors in impulse identification are: (1) Excessive Time, (2) Excessive Sharpness, and (3) Insufficient Wave-C Time. These three errors are committed not only by beginners but also by experienced analysts, and over 70% of incorrect wave counts fall into these categories.

Major Error Types

1. Time Extension Error

• Symptom: A wave classified as an impulse takes excessively longer than expected
• Cause: Most commonly, a corrective pattern (especially a complex combination) has been misinterpreted as an impulse
• Identification: An impulse typically completes within 61.8%–100% of the preceding correction's time. If this range is significantly exceeded, reassess the possibility of a correction.
• Solution: Reanalyze time ratios and reclassify as a corrective pattern (Diametric, complex correction, etc.) rather than an impulse

2. Excessive Sharpness Error

• Symptom: An excessively sharp, rapid move is judged to be an impulse
• Cause: The primary cause is mistaking wave-C of a complex corrective pattern (especially wave-C of a zigzag) for an independent impulse
• Identification: A genuine impulse includes appropriate retracements (waves 2 and 4). A move that advances sharply in one direction without retracements has a high probability of being wave-C of a correction.
• Solution: Analyze internal structure in detail and verify that waves 2 and 4 clearly exist

3. Insufficient Wave-C Time Error

• Symptom: Wave-C of a complex correction appears to have completed in less time than expected
• Cause: Wave-C's internal structure has been oversimplified, leading to a premature judgment that a still-in-progress wave-C is complete
• Identification: Wave-C typically accounts for at least 61.8% of the combined A+B wave duration. If shorter, wave-C may still be in progress.
• Solution: Subdivide wave-C's internals for more granular analysis and verify whether additional waves remain

Detailed Error Analysis

3rd Wave Extension Misjudgment

• Error Scenario: A simple strong move is incorrectly interpreted as a 3rd wave extension
• Criterion: Wave-3 must be at least 161.8% of wave-1 to qualify as an extension
• Verification: Confirm that the internal structure is composed of 9 or more waves
• Prevention: Strictly apply the 161.8% rule and also verify time relationships (whether wave-3 is also the longest in duration)

Premature 5th Wave Failure Judgment

• Error Scenario: A still-in-progress wave-5 is prematurely concluded as a failure
• Risk: Missing additional upside/downside and trading in the wrong direction
• Confirmation Factors: Comprehensively analyze momentum indicators (RSI divergence), volume (declining trend), and time relationships (wave-5 duration)
• Prevention: Reconfirm with momentum indicators and allow sufficient time to pass before making a judgment. At least three confirmation conditions must be simultaneously met before entry
