61.8% Golden Ratio โ€” price retraced from the swing high and found support here. Notice the consolidation and early recovery forming at this level. Dummy data for illustration.

Definition

Fibonacci retracement is a technical analysis framework that identifies potential support and resistance zones by applying key Fibonacci ratios โ€” 23.6%, 38.2%, 50%, 61.8%, and 78.6% โ€” to the vertical range of a significant price swing. The levels are derived by dividing the swing range by each ratio and projecting horizontal lines onto the chart. The 61.8% level, the inverse of the golden ratio (ฯ† โ‰ˆ 1.618), is the most institutionally significant, frequently acting as a decision zone for large-scale re-entry during pullbacks. In practice, Fibonacci levels are most reliable when they align with prior structural support, moving averages, or volume-weighted price nodes โ€” creating confluence zones that attract order flow from multiple participant types.

How to Use It
1
Identify the swing

Find a clear, well-defined swing low (the bottom) and swing high (the top) within the trend you want to analyse. The more obvious and significant the move, the more meaningful the resulting levels โ€” small, choppy ranges produce noisy, unreliable retracements.

2
Draw from low to high (uptrend)

In an uptrend, anchor your Fibonacci tool at the swing low and drag to the swing high. The retracement levels now project where price might pull back to before the uptrend resumes. In a downtrend, reverse the direction โ€” anchor at the swing high and drag to the swing low.

3
Watch for confluence

A Fibonacci level becomes far more significant when it overlaps with a prior support/resistance zone, a key moving average (50-day, 200-day), or a high-volume price node. One level alone is noise โ€” confluence is signal. Two or three reasons for price to react at the same area is when traders get aggressive.

4
Wait for price reaction

Never assume a Fibonacci level will hold just because it exists. Wait for confirming price action โ€” a rejection wick, a bullish engulfing candle, or a spike in volume at the level. This confirmation separates a meaningful bounce from a price that's about to slice straight through.

Key Levels
Level
Name & Notes
Strength
0%
Swing High

The starting point of the retracement. Price is at the top of the prior move.

Weak
23.6%
Shallow Retracement

A minor pullback, usually seen in very strong momentum-driven trends. Often barely registers as a pause before continuation.

Weak
38.2%
First Major Level

The first serious test of trend conviction. A common first support zone in a healthy uptrend โ€” often where early buyers step back in.

Moderate
50%
Psychological Midpoint

Not a true Fibonacci ratio, but widely watched. Represents exactly half the prior move. Psychologically significant to market participants.

Moderate
61.8%
The Golden Ratio

The most important level. Derived from dividing any Fibonacci number by the one that follows it. Frequently acts as the final support before a trend resumes โ€” the line that separates pullback from reversal.

Strong
78.6%
Deep Retracement

A deep pull-back that severely tests trend conviction. A break and hold below 78.6% often signals that a full trend reversal is underway rather than a healthy pullback.

Weak
100%
Swing Low

A full 100% retracement back to the swing low. If price reaches here, the prior uptrend is likely fully invalidated.

Weak
Limitations & Drawbacks

Fibonacci levels are partly self-fulfilling โ€” they work because so many traders watch them and place orders at the same zones, creating the very support they predict. This means they can fail suddenly and violently when sentiment shifts or when an unexpected catalyst (earnings miss, macro shock) overrides the technical setup. They also offer zero insight into fundamental value โ€” they say nothing about whether a company deserves to recover at any given level. Use them for timing entries in stocks you already have fundamental conviction in. Never use a Fibonacci level as the primary reason to buy.
