Fibonacci Ratio Relationships

​

Overview

• Length relationships between impulse waves;
• Retracement depth of corrective waves;
• Projection zones for future target prices…

• 0.618: the golden ratio;
• 1.618: the inverse of the golden ratio, also commonly used as an “extension ratio.”

Fibonacci is not a “magic turning point,” but a set of ratio tools widely watched by market participants, used to help us estimate:

• how deep a pullback might reasonably go;
• which areas an impulse wave might extend to before it’s “probably enough.”

1. Impulse-wave ratios: common length relationships among Waves 1, 3, and 5;
2. Corrective-wave ratios: common Fibonacci retracement levels during pullbacks;
3. Price projections: how to use a prior move’s length to estimate target zones.

Ratio Relationships

​

Impulse-Wave Ratios

the wave’s high − low (for an up wave), or the reverse (for a down wave).

1. Common extension ratios for Wave 3
   • Wave 3 is often viewed as the “main thrust” and is frequently the longest and most powerful segment of the impulse;
   • Common length relationships:
     • Wave 3 ≈ 1.618 × Wave 1
     • or Wave 3 ≈ 2.618 × Wave 1 (especially in strong trends)
   Simple example:
   • Wave 1 rises from 10 to 14, length = 4;
   • If Wave 3 extends by 1.618: length ≈ 4 × 1.618 ≈ 6.47; if Wave 3 starts near 12, then the rough target is: 12 + 6.47 ≈ around 18.5.
2. Relationship between Wave 5 and Wave 1
   • In many cases:
     • Wave 5 ≈ the length of Wave 1 (a symmetrical structure);
   • Or:
     • Wave 5 ≈ 0.618 × the total length of (Wave 1 + Wave 3) (a more conservative extension);
   Example:
   • Wave 1: length 4
   • Wave 3: length 8
   • Then (1 + 3) total length = 12;
   • If Wave 5 ≈ 0.618 × 12 ≈ 7.4, then from the start of Wave 4, an upward move of about 7.4 is a reference zone.
3. Among Waves 1, 3, and 5, one wave usually does not extend
   • Generally:
     • Either Wave 3 extends, while Waves 1 and 5 are more similar;
     • Or Wave 5 extends, while Waves 1 and 3 are relatively similar;
   • In other words,

     Among Waves 1, 3, and 5, one wave is usually “especially long,” with a clear Fibonacci relationship to the other two.

• These ratios are common tendencies, not requirements;
• In practice, you mostly:
  • Use Wave 1’s length to estimate potential target bands for Waves 3 and 5;
  • Use Wave 3’s length to judge whether the current Wave 5 looks “somewhat over-extended.”

​

Corrective-Wave Ratios

• 0.236: a shallow pullback, suggesting a very strong trend;
• 0.382: a common pullback in strong trends;
• 0.5: a middle-of-the-road level (strictly speaking not a Fibonacci number, but widely used in practice);
• 0.618: a deeper pullback, often seen in Wave 2;
• 0.786: a very deep pullback, close to “giving back almost all” of the prior advance.

1. Wave 2 retracement ratios (often deeper)
   • Wave 2 often retraces Wave 1 by:
     • 0.5, or
     • 0.618, and sometimes deeper;
   • But in theory it should not fully return to the start of Wave 1 (otherwise Wave 1 wouldn’t be valid).
   Example:
   • Wave 1 rises from 10 to 16, length = 6;
   • If Wave 2 retraces 0.618:
     • retracement amount = 6 × 0.618 ≈ 3.7;
     • Wave 2 low ≈ 16 − 3.7 ≈ around 12.3;
   • If you’re looking for a buy zone in Wave 2, the 12–13 area becomes a natural focus.
2. Wave 4 retracement ratios (often shallower)
   • Compared with the “deep correction” of Wave 2, Wave 4 is usually relatively shallow;
   • Common retracement:
     • 0.236–0.382 of the prior wave (Wave 3) length;
   • This also matches the “alternation principle”: if Wave 2 is deep, Wave 4 tends to be shallow; if Wave 2 is shallow, Wave 4 may be somewhat deeper.
3. A vs. C ratios inside corrections
   • In an ABC correction:
     • Wave C length ≈ Wave A length (C ≈ 1.0 × A) is very common;
     • Or Wave C ≈ 1.618 × Wave A, representing an “extended C.”
   Example:
   • Wave A drops from 20 to 16, length = 4;
   • If C ≈ 1.0 × A, then from the start of Wave B, a downward move of about 4 is a reference;
   • If C ≈ 1.618 × A, then from the start of Wave B, a downward move of about 6.47 is a reference.

Price Projections

1. Use Wave 1 to project Wave 3
   • Known:
     • Wave 1 length = L1;
     • Wave 2 end price = P2.
   • Common targets:
     • Wave 3 target 1 ≈ P2 + 1.0 × L1;
     • Wave 3 target 2 ≈ P2 + 1.618 × L1;
     • Wave 3 target 3 ≈ P2 + 2.618 × L1 (strong extension).
2. Use the entire 0–3 move to project Wave 5
   • Known:
     • Total advance from 0 to 3 = L03;
     • Wave 4 end price = P4.
   • Common targets:
     • Wave 5 target ≈ P4 + 0.382 × L03;
     • or P4 + 0.618 × L03;
   • Depending on overall rhythm and how strong the prior waves were.
3. Use Wave A to project Wave C
   • Known:
     • Wave A length = LA;
     • Wave B end price = PB;
   • Common projections:
     • Wave C target 1 ≈ PB − 1.0 × LA;
     • Wave C target 2 ≈ PB − 1.618 × LA (extended C).

In practice, you usually plot several Fibonacci projection results on the chart, look for areas where multiple ratios overlap (Fibonacci Cluster), and treat them as more important support/resistance bands rather than a single exact price.

Core Concepts

1. “Price zones,” not “price points”
   • Fibonacci levels are estimation references, not turning points precise to decimals;
   • A more reasonable approach is:
     • Leave some “tolerance” above and below key ratios to form a zone;
     • Within the zone, observe price action, volume, and other technical signals in combination.
2. Retracement vs. extension
   • Retracement: a counter-move correction to the prior leg, such as 0.382, 0.5, 0.618;
   • Extension: projecting additional future space beyond the prior leg, such as 1.272, 1.618, 2.618;
   • Tools differ in most platforms (“retracement tool” vs “extension tool”), and conceptually they should not be mixed up.
3. The importance of multi-timeframe confluence
   • When:
     • a daily Fibonacci retracement level,
     • a key weekly support,
     • a prior swing high/low
   • cluster near the same price area, that zone often has stronger support/resistance significance.
4. Fibonacci is more meaningful when paired with wave structure
   • Pulling a Fibonacci retracement by itself can still be useful;
   • But when you can clearly identify:
     • this is the start and end of Wave 1;
     • this is the length of Wave 3;
     • this is Waves A and B inside an ABC;
   • then drawing ratios off those waves → produces results that fit structure better than “randomly picking two points and dragging a tool.”
5. It’s a “probability tool,” not a “guarantee”
   • Fibonacci ratios are useful largely because they are widely watched by many traders;
   • Any ratio can be pierced, false-broken, or even completely ignored;
   • Always remember:

     Fibonacci helps you “plan risk-reward more logically,” not “predict the future.”

​

Practical Applications

​

Case 1: Using Fibonacci retracements to find a Wave 2 buy zone

• Wave 1: rises from 10 to 16, length = 6;
• Then it begins to pull back (you judge this as a potential Wave 2).

1. Draw Fibonacci retracements from 10 (Wave 1 start) to 16 (Wave 1 end);
2. Key focus:
   • 0.5 retracement: 13;
   • 0.618 retracement: about 12.3;
3. When price pulls back into the 13–12.3 zone:
   • Observe:
     • whether a stabilization pattern appears (long lower wick, small bullish stabilization candles, etc.);
     • whether volume expands and selling pressure eases;
   • If so, treat this zone as a potential Wave 2 completion area and build in tranches;
   • A stop can be set around 12 or lower to guard against an incorrect wave interpretation.

​

Case 2: Using the 1.618 ratio to project a Wave 3 target

• Wave 1: 10 → 16, length = 6;
• Wave 2 pulls back to 13 and stabilizes; you believe Wave 3 may be starting.

1. Compute Wave 3 targets:
   • Target 1 (equal length): 13 + 6 = 19;
   • Target 2 (1.618 extension): 13 + 6 × 1.618 ≈ 13 + 9.7 ≈ 22.7;
2. Combine with chart structure:
   • If 19 is near a prior key high or resistance zone, → treat it as the first observation point for trimming/taking profit;
   • If price breaks through strongly on expanding volume, → you can continue holding and look for a run toward 22–23.
3. As price approaches these target bands:
   • You don’t have to sell everything, but at least:
     • trim some to lock in profits;
     • or raise your stop to a higher level (e.g., near 19) to protect gains.

​

Case 3: Using Wave A length to estimate the end of Wave C

• Wave A: 3,300 → 3,000, decline = 300 points;
• Wave B rebounds to 3,150.

1. From the Wave B end at 3,150, project downward using the Wave A length:
   • C = 1.0 × A: 3,150 − 300 = 2,850;
   • C = 1.618 × A (extended): 3,150 − 300 × 1.618 ≈ 3,150 − 485 ≈ 2,665;
2. Then check the chart:
   • If around 2,850 is a prior clear Wave 4 consolidation zone, or overlaps with key support and a high-volume congestion area, → then the 2,850 area becomes a highly important candidate support zone.
3. Practical strategy:
   • Watch for high-volume stabilization and structural signals around the 2,850 area and build medium-term exposure in tranches;
   • If price breaks straight through 2,850 and continues probing toward 2,700 or even around 2,660, → reassess: whether the market is in a larger-degree trend reversal rather than a simple ABC correction.

FAQs

​

Q1: Why do Fibonacci levels “seem to work often”? Is it mysticism?

1. Many traders, technical analysts, and systematic strategies watch these ratios;
2. When price approaches certain key ratios (such as 0.618, 1.618):
   • Some begin placing orders proactively;
   • Algorithmic strategies adjust dynamically;
   • The market naturally shows “more reaction” in these areas.

• guaranteed to work;
• nor powered by anything mysterious.

Treat it as a widely used technical reference framework, not some “mystical coordinate system.”

​

Q2: Why do some moves completely ignore Fibonacci levels?

1. The trend is extremely strong or extremely weak
   • In very strong trends, pullbacks may not even reach 0.382 before making new highs;
   • In very weak or panic selloffs, price may “ignore” every retracement and keep slicing through.
2. Your anchor points are inappropriate
   • For example:
     • using the wrong wave as the start/end;
     • pulling the tool from a less relevant point when there is a clearly better swing high/low;
   • If the anchors are wrong, Fibonacci will naturally “miss.”
3. The degree you chose doesn’t match your trading horizon
   • A line drawn on a 5-minute chart may have little relevance to a daily trend;
   • Conversely, using weekly Fibonacci levels to guide ultra-short-term trades can be misaligned with practical needs.

• whether your wave identification is reasonable;
• whether you chose the right swing highs/lows;
• whether the degree matches your trading horizon.

​

Q3: How should I use overlapping Fibonacci levels?

A “focus zone” or “Fibonacci cluster”

1. Plot several key ratios (e.g., 0.382, 0.5, 0.618, 1.0×A, 1.618×A);
2. Find areas where levels clearly cluster on the price axis, such as:
   • 0.618 retracement + C=1.0×A + a prior Wave 4 zone near the same band;
3. Within the cluster:
   • Be more willing to attempt:
     • scaling in/out in tranches;
     • tighter observation of tape/price action and volume changes;
   • While still using strict stops— once the cluster is decisively broken, accept that the market chose a “more extreme” path.

In short: Overlap = priority, but it still requires “price-action confirmation + risk control” to work together.

​

Summary

• Fibonacci ratios are among the most important auxiliary tools in wave theory, widely used for:
  • Impulse-wave length relationships (1.0, 1.618, 2.618 among Waves 1, 3, 5);
  • Corrective-wave retracement depth (retracement levels such as 0.382, 0.5, 0.618);
  • Price projections (using a completed wave to estimate the next wave’s target zone).
• Its essence is:

  A “ratio ruler” widely watched in markets— not magical in itself, but useful because of consensus.

• In practice, remember:
  • Use price zones rather than single prices;
  • Combine wave structure, support/resistance, price-volume relationships, and multi-timeframe confluence;
  • Always define stops and position limits near Fibonacci levels, using it as a tool to improve risk-reward, not an “absolute predictor.”
