Fibonacci levels

Reading the market: charts, tools and instruments3 min read
What you learn in 3 minutesFibonacci levels are a set of horizontal lines drawn at fixed proportions of a price move. The word comes from the surname of Leonardo Fibonacci, but on a chart the tool is simply a grid: you pick a swing low and a swing high, and the platform divides that distance into the same fractions every time. The levels most platforms show by default are 23.6 per cent, 38.2 per cent, 50 per cent, 61.8 per cent and 78.6 per cent of the move. What they mark is not a prediction. They mark prices where many other people have drawn the same lines, so orders and attention tend to collect there.

Reading the grid on the platform

When a Fibonacci tool is opened on a chart, the platform asks for two clicks: one on a swing low, one on a swing high. The tool then draws horizontal lines between those two prices at fixed fractions of the distance. On AUD/USD, if the swing low is 0.6600 and the swing high is 0.6700, the distance is 0.0100. The 23.6 per cent line sits 0.0024 below the high, at 0.6676. The 38.2 per cent line sits 0.0038 below the high, at 0.6662. The 50 per cent line sits 0.0050 below the high, at 0.6650. The 61.8 per cent line sits 0.0062 below the high, at 0.6638. The 78.6 per cent line sits 0.0079 below the high, at 0.6621.

The fractions are not random. Each one comes from dividing numbers in the Fibonacci sequence, but the platform does that work for you. What matters is that the lines are always in the same place relative to the two points you chose. The 50 per cent level is not a Fibonacci ratio in the strict sense, yet most platforms include it because traders watch it. The 61.8 per cent level is the one most often discussed, but it has no special power over price. The grid is a measuring tool, not a forecast.

The same grid can be drawn on a fall instead of a rise. If price moves from 0.6700 down to 0.6600, the tool still divides that distance into the same fractions. The 50 per cent level is still 0.6650. The lines do not know direction. They only mark prices that are fixed proportions of the move you selected. That is why two people can draw the same tool on the same chart and get different lines: they chose different swings.

Why the lines attract attention

A Fibonacci level is not a physical barrier. It is a price where a large number of people have drawn the same line. When many charts show a line at 0.6638 on AUD/USD, orders tend to collect around that price. Some are limit orders placed in advance. Some are stop losses. Some are simply traders watching to see what happens there. The level itself does nothing. The crowd around it does.

This is why a reaction at a Fibonacci level can look meaningful. Price may slow down or turn near 0.6638 because buyers and sellers are both active there. But the same reaction could happen at any price where enough orders sit. The Fibonacci line is a convenient label for a area that already mattered. If you remove the grid, the price is still the same. The grid only helps you notice it.

The levels also overlap with other tools. A 50 per cent line might sit near a previous day's high or a round number like 0.6650. When two or more reasons point to the same price, attention grows. That overlap is not proof of anything. It is simply a place where more people are likely to be watching. The Fibonacci grid is one way to find those places, not the only way.

Choosing the swing points

The grid depends entirely on which low and which high you select. On a one-hour chart of AUD/USD, the swing low might be 0.6600 and the swing high 0.6700. On a five-minute chart, the same period might show a low of 0.6620 and a high of 0.6680. The fractions are the same, but the prices are different. Neither choice is wrong. They answer different questions about different time frames.

A common approach is to pick the most obvious swing that a casual observer would see. That usually means the lowest low and the highest high before a clear change in direction. If the move is messy, with several small swings, the grid becomes less useful. A clean move from a clear low to a clear high gives lines that more people are likely to have drawn. A messy move gives lines that few people share.

You can also draw more than one grid. One on the daily swing and one on the hourly swing will give you two sets of lines. Where they cluster, attention may be higher. Where they disagree, the picture is less clear. There is no rule that says you must use only one grid. The tool is flexible, and so is the market.

Doing it once, step by step

The following steps walk through drawing a Fibonacci grid on AUD/USD and checking whether the levels matter. Do them once on a demo chart before using real money.

  1. 01

    Open the Fibonacci tool

    Find the Fibonacci retracement tool in your platform's drawing menu. It is usually shown as a small grid icon. Select it, then click once on a clear swing low and once on a clear swing high. The platform will draw the lines automatically.

  2. 02

    Note the default levels

    Most platforms show 23.6, 38.2, 50, 61.8 and 78.6 per cent. Write down the price at each line. On a move from 0.6600 to 0.6700, the 50 per cent line is 0.6650. The 61.8 per cent line is 0.6638.

  3. 03

    Check the pip distance

    Subtract each level from the high to see how many pips away it is. The 61.8 per cent level is 0.6700 minus 0.6638, which is 62 pips. This tells you how far price would need to move to reach that line.

  4. 04

    Look for other evidence

    At each Fibonacci level, look for a previous reaction, a round number, or a moving average. If nothing else agrees, the line is just a line. Do not act on the Fibonacci level alone.

  5. 05

    Watch how price behaves

    Observe whether price slows, reverses, or passes straight through the level. A strong move through a level tells you that the orders there were not enough to stop it. A weak reaction tells you that attention was present.

  6. 06

    Record the result

    Write down what happened at each level without judging it. Over time, you will see that some levels attract reactions and others do not. That record is more useful than any single prediction.

The mistake most people make here

The common mistake is to treat a Fibonacci level as a signal on its own: price touches 61.8 per cent, so the reader buys. A level is only a place on the chart, not a reason to act. The grid also depends entirely on which low and which high you chose, and two people can pick different swings and get different lines. Draw the grid, then look for other evidence at that price, such as a clear reaction or a level that has mattered before. If nothing else agrees, the line means very little.

Check yourself

A move runs from 0.6600 to 0.6700. Where is the 50 per cent level?

The move is 0.0100. Half of it is 0.0050. Subtract from the high: 0.6700 minus 0.0050 = 0.6650.

The 61.8 per cent level sits at 0.6638. How many pips is that below the high at 0.6700?

0.6700 minus 0.6638 = 0.0062, which is 62 pips.

One standard lot of AUD/USD is 100,000 units and one pip is 0.0001. What is one pip worth in US dollars?

100,000 x 0.0001 = 10 US dollars. In Australian dollars it depends on the exchange rate at the time.

Questions that come up next

If two people draw the same Fibonacci grid on AUD/USD, why do they get different lines?

The tool divides whatever distance you select, so the lines depend on the two points you clicked. One person may choose a swing low at 0.6600 and a swing high at 0.6700, while another picks a smaller swing inside that range. Both grids are drawn correctly, but they mark different prices. There is no single correct grid, only the one that matches the swings you chose to measure.

Does price have to react at a Fibonacci level?

No. A Fibonacci level is a price, not a rule, and price can pass straight through it without slowing. A reaction happens when enough orders sit at that price, and orders can sit at any price. The level only tells you where many people have drawn the same line. If nothing else on the chart agrees with it, the line carries little weight.

Why do platforms include 50 per cent when it is not a Fibonacci ratio?

The 50 per cent level is not produced by dividing numbers in the Fibonacci sequence. Platforms include it because a half of a move is an obvious point that many people watch anyway. Because so many charts show it, orders and attention can collect there just as they do at the other lines. Its presence is a convention, not a mathematical result.

What is one pip worth on AUD/USD in Australian dollars?

One standard lot is 100,000 units and one pip is 0.0001, so a pip is worth 10 US dollars. Converting that to Australian dollars depends on the AUD/USD exchange rate at the time, so the figure moves. Brokers also differ in how they round displayed prices and in the spreads and commissions they charge. Check the pip value your own platform shows.

Can a Fibonacci grid be drawn on a falling move?

Yes. If price falls from 0.6700 to 0.6600, the tool divides that distance into the same fractions, and the 50 per cent level is still 0.6650. The lines do not know which direction the move went. They only mark fixed proportions of the distance between the two points you selected.

What should I look for at a Fibonacci level before deciding anything?

Look for evidence other than the line itself, such as a clear reaction in price or a level that has mattered before. If those agree with the Fibonacci price, the area has more behind it. If nothing else agrees, the line means very little on its own. The grid is a place to look, not a reason to act.

The words used on this page

swing low
A point on the chart where price stopped falling and turned upward, with higher prices on both sides. It is one of the two points you click when drawing a Fibonacci grid. Different people can choose different swing lows.
swing high
A point where price stopped rising and turned downward, with lower prices on both sides. It is the other point you click when drawing the grid. The distance between the swing low and the swing high is what the tool divides.
pip
A small fixed step in a currency price. On AUD/USD one pip is 0.0001, so a move from 0.6638 to 0.6700 is 62 pips. Pip value in Australian dollars changes with the exchange rate.
limit order
An order placed in advance to buy or sell at a chosen price. Many limit orders can sit near a Fibonacci level because people expect activity there. The orders, not the line, are what may affect price.
stop loss
An order that closes a position at a chosen price to limit a loss. Stops often collect near levels that many people watch, including Fibonacci lines. Their presence can add to activity at that price.
spread
The gap between the price at which you can buy and the price at which you can sell. It is a cost on every trade and it varies between brokers. It is separate from the Fibonacci grid.

What to take away

  • A Fibonacci grid divides a chosen move into fixed fractions, so its lines depend on the two points you picked.
  • The lines mark prices where many people have drawn the same lines, not prices where price must turn.
  • A level is a place to look for other evidence, never a reason to act by itself.
  • Pip value in Australian dollars moves with the exchange rate, and brokers differ in rounding, spreads and commissions.
