Fibonacci Trading Guide: Retracements, Extensions & Advanced Cluster Analysis

What Are Fibonacci Numbers?

The Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144...) was discovered by Leonardo Fibonacci in the 13th century. Each number is the sum of the previous two.

The key ratios derived from this sequence appear throughout nature, art, and — remarkably — financial markets.

Key Fibonacci Ratios

Fibonacci Retracements

What They Measure

Retracements measure how much of a previous move gets "pulled back" before the trend resumes.

How to Draw

1. Identify a significant swing (Low to High for uptrend, High to Low for downtrend)
2. Place the Fibonacci tool from the START of the move to the END
3. The levels automatically appear between 0% and 100%
4. Watch for price reactions at these levels

The Key Levels

0.382 (38.2%) — Shallow retracement

• Strong trends often only pull back to 38.2%
• Quick bounce = momentum is still high

0.500 (50%) — The half-way mark

• Not a true Fibonacci number but heavily watched
• Many traders place orders here

0.618 (61.8%) — The Golden Ratio

• THE most important Fibonacci level
• If a trend is healthy, it should hold 61.8%
• Breaking 61.8% often signals trend change

0.786 (78.6%) — Deep retracement

• Last chance for the trend to survive
• Often seen in complex corrections

Trading Rules

1. Draw from the CLEAR swing low to swing high (or vice versa)
2. Enter at 38.2%, 50%, or 61.8% when you see price reaction (candlestick pattern, support bounce)
3. Stop loss below the next Fibonacci level or the swing low
4. Take profit at the previous high (or extension levels)
5. Confirm with other tools — S/R levels, moving averages, candlestick patterns

Fibonacci Extensions

What They Measure

Extensions project where the trend might go BEYOND the original move.

Key Extension Levels

How to Use

1. Draw the Fibonacci from swing low to swing high
2. Price retraces to a key level (38.2%, 50%, 61.8%)
3. When price resumes the trend, watch the extension levels as targets
4. 1.272 extension = first target (conservative)
5. 1.618 extension = main target
6. 2.618 extension = aggressive target

Fibonacci Confluence (The Power Play)

What is Confluence?

When multiple Fibonacci levels from different swings align at the same price zone, it creates a high-probability support or resistance area.

How to Find Confluence

1. Draw Fibonacci retracements from multiple significant swings (not just one)
2. Look for areas where 2-3 different Fibonacci levels cluster together
3. The more levels that converge at a price zone, the stronger the S/R

Example

• Fib from Swing A: 61.8% retracement at 1.0950
• Fib from Swing B: 38.2% retracement at 1.0955
• Confluence zone: 1.0950-1.0955 — extremely strong support

Confluence with Other Tools

Fibonacci is most powerful when combined with:

• Moving Averages — Fibonacci level + 200 EMA = very strong
• Previous S/R — Fibonacci level + previous support = very strong
• Trend Lines — Fibonacci level + ascending trendline = very strong
• Round Numbers — Fibonacci level + 1.1000 = psychological + mathematical

Common Mistakes

Fibonacci Trading Strategy

The 61.8% Pullback Strategy

Setup:

1. Identify a strong trending move (impulse)
2. Wait for price to retrace to the 50-61.8% zone
3. Look for a bullish/bearish candlestick confirmation at the zone
4. Bonus: zone coincides with a moving average or S/R level

Entry: On the confirmation candle close Stop Loss: Below/above the 78.6% level Target 1: Previous swing high/low (0% level) Target 2: 1.618 extension

Risk:Reward: Typically 1:2 to 1:4
