How to Use Fibonacci and Which Levels Most Traders Actually Watch

Fibonacci is one of the most widely used drawing tools in trading. It answers two questions: where might a pullback stop, and if price keeps going, where should the target be. It does not predict the future, but it helps you plan your entry, Stop loss and Take profit in advance, in a consistent way.

Where do these numbers come from

The Fibonacci sequence is 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144 … Each number is the sum of the two before it. Divide numbers in the sequence by each other and you get the ratios used as levels on the chart.

Level	Source
0.618	55 ÷ 89 ≈ 0.618, known as the golden ratio
0.382	34 ÷ 89 ≈ 0.382, or 0.618 × 0.618
0.236	21 ÷ 89 ≈ 0.236
0.786	Square root of 0.618
1.272	Square root of 1.618
1.618	89 ÷ 55 ≈ 1.618
2.618	1.618 × 1.618

0.5 is not a Fibonacci number. It comes from an old idea that price often retraces about half of the previous swing. Traders use it so much that almost every platform includes it.

Part of the reason Fibonacci often works is that many people watch the same levels, so orders pile up around them. It is not because the market knows maths.

Fibonacci Retracement: finding the pullback

Use Retracement when price has made a clear swing and starts to pull back. You measure how much of the original swing it has given back, as a percentage.

Popular levels and what they mean

Level	How traders read it
0.236	A shallow pullback, often seen in very strong trends
0.382	A normal pullback in a healthy trend, the first level many start watching
0.5	Half the swing, a level many people watch
0.618	The most popular level. If price clearly breaks below it, the trend is getting weaker
0.786	A deep pullback, used as a last line or a place to put the Stop loss just beyond

The zone between 0.5 and 0.618 is often called the golden zone. In crypto, traders pay special attention to 0.618 to 0.65, known as the golden pocket.

How to draw it the right way round

1. Find a clear swing first. Pick an obvious low and high on the chart, not a tiny wiggle.
2. Uptrend: draw from the low to the high. Downtrend: draw from the high to the low.
3. In TradingView and MT4/MT5, level 0 sits where you finish the drag and level 1 sits where you started.
4. Check every time: 0.618 must be closer to the start of the swing than 0.382. If it is the other way, you drew it backwards.

You can draw from the wicks or the candle bodies, but stick with one. Most traders use the true high and low, including the wicks.

Formula for each level’s price

Uptrend: retracement price = high − (level × swing length)

Example: EURUSD rises from 1.0800 to 1.1000. The swing length is 0.0200, or 200 pips.

Level	Calculation	Price
0.236	1.1000 − 0.236 × 0.0200	1.09528
0.382	1.1000 − 0.382 × 0.0200	1.09236
0.5	1.1000 − 0.5 × 0.0200	1.09000
0.618	1.1000 − 0.618 × 0.0200	1.08764
0.786	1.1000 − 0.786 × 0.0200	1.08428

Fibonacci Extension: finding profit targets

If price pulls back and then climbs to a new high, levels above 1 give a rough idea of how far it might go.

Uptrend: target price = high + ((level − 1) × swing length)

Level	Price (same example)	What it’s used for
1.272	1.10544	First target, where many take partial profit
1.618	1.11236	The most popular target
2.0	1.12000	Used in strong trends
2.618	1.13236	A distant target, rarely used

The Trend-Based Fib Extension tool

TradingView has another version that uses 3 points: the swing start, the swing end, and the pullback low. It projects the original swing length from the pullback point.

Example: the swing is 0.0200 long and the pullback reaches 1.0876. Level 1.0 is 1.0876 + 0.0200 = 1.1076, and level 1.618 is 1.0876 + 0.0324 ≈ 1.1200.

Example trade plan

This example only shows the thinking process. It is not a recommendation to buy or sell.

• Uptrend from 1.0800 to 1.1000. Price pulls back to around 0.618 at 1.0876, which also lines up with old support
• Wait for a candle that confirms buyers are stepping back in, then buy at 1.0876
• Put the Stop loss below the 0.786 level at 1.0840, risking 36 pips
• First target is the previous high at 1.1000, a gain of 124 pips, Risk:Reward about 1:3.4
• Second target is 1.272 at 1.1054

Before entering for real, work out your lot size from the amount you are willing to lose and this 36-pip distance, not from how confident you feel.

What to combine it with

A Fibonacci level alone is not enough reason to trade. It gains weight when these line up at the same spot:

• Old support or resistance
• Round numbers, such as 1.0900, or 2,000 on gold
• A moving average you use regularly
• A reversal candlestick pattern in the zone
• The same direction as the trend on a higher timeframe

Common mistakes

• Drawing on small, meaningless swings. The clearer the swing and the bigger the timeframe, the more people watch the levels
• Treating a level as an exact line. Price often pokes a little past it, so think in zones
• Redrawing again and again until it shows what you want to see
• Trading against the main trend just because price touched a Fibonacci level
• Turning on every level until the chart is cluttered. Only show the ones you actually use

Suggested settings

Showing 0, 0.236, 0.382, 0.5, 0.618, 0.786, 1, 1.272, 1.618 is enough for most people. If you trade crypto, you can add 0.65. Turn on 2.618 only when the market is really running.
