Fractals Indicator: How the Five-Bar Rule Marks Swing Points
The fractals indicator, based on Bill Williams' five-bar rule, marks a swing high when the middle bar of five has the highest high of the set, and a swing low when the middle bar has the lowest low. Each fractal is confirmed only after two more bars have formed, so it is a description of past price.
In brief
What is the fractals indicator?
A fractal is a description of past price, not a signal. Here is the five-bar rule, a worked EXAMPLE of an up and a down fractal, and why each one is known only after two later bars.
Key takeaways
- A fractal is built from a run of consecutive bars: at least five in the MetaTrader 5 wording, and five by default on TradingView. An up fractal has the highest high in the middle bar, and a down fractal has the lowest low.
- The two bars on each side of the middle bar must both be lower (for an up fractal) or higher (for a down fractal).
- A fractal is confirmed only after two later bars have formed, so it always appears with a delay.
- Fractals mark past swing points. They are not entry or exit signals, and they do not show where price will go next.
- Settings can differ between platforms. TradingView lets you change the number of bars, so check the count before you compare charts.
What the fractals indicator shows
The fractals indicator marks local turning points on a price chart. The TradingView support article on Williams fractals credits Bill Williams and his 1995 book Trading Chaos.
A fractal is a pattern of five bars, not a single bar. Its middle bar is the extreme of the set. An up fractal marks a swing high and a down fractal marks a swing low. For the basics of trading itself, start with what is trading.
The five-bar rule for an up fractal and a down fractal
Read the rule from the middle bar outward. In an up fractal, the middle bar's high must be the highest of the five, and each of the two bars on either side must have a lower high. In a down fractal, the middle bar's low must be the lowest, and each of the two bars on either side must have a higher low.
| Element | Up fractal (swing high) | Down fractal (swing low) |
|---|---|---|
| Bars in the set | Five by default (TradingView); MetaTrader 5 says at least five | Five by default (TradingView); MetaTrader 5 says at least five |
| Middle bar | Has the highest high of the five | Has the lowest low of the five |
| Two bars on the left | Each has a lower high than the middle bar | Each has a higher low than the middle bar |
| Two bars on the right | Each has a lower high than the middle bar | Each has a higher low than the middle bar |
| When it is known | By the rule, after the second bar to the right closes | By the rule, after the second bar to the right closes |
Sources: MetaTrader 5 help, Fractals (Bill Williams' Indicators), which says at least five successive bars, and TradingView support, Williams fractal indicator, which uses five candlesticks by default. Both describe the middle-bar extreme. The timing row follows from the rule itself; TradingView describes the lag as two or more candlesticks, give or take. Verified on 10 November 2026.
Neither cited source says what happens when a bar beside the middle bar has the same high or low. Read literally, both require 'lower' or 'higher', which would exclude a tie. Check how your platform handles equal values before you compare its marks with another chart.
Worked EXAMPLE: an up fractal on five highs
This EXAMPLE uses made-up values, not market data. Five consecutive bars are numbered 1 to 5 from left to right, and only their highs are used.
| Bar | High | Position | Check against the middle bar |
|---|---|---|---|
| 1 | 104.20 | Left side | Lower than 106.40 |
| 2 | 105.10 | Left side, nearest | Lower by 1.30 (106.40 minus 105.10) |
| 3 | 106.40 | Middle bar | Highest of the five |
| 4 | 105.80 | Right side, nearest | Lower by 0.60 (106.40 minus 105.80) |
| 5 | 105.30 | Right side | Lower than 106.40 |
EXAMPLE values only. Bar 3 is the up fractal, and it is confirmed when bar 5 closes.
Bar 3 is the up fractal because its high of 106.40 is higher than all four neighbours. The fractal is known only at the close of bar 5, the second bar to the right of the middle bar.
Worked EXAMPLE: a down fractal on five lows
The mirror case uses the same five-bar layout with lows. This EXAMPLE is also made up. The middle bar is bar 3, and its low is the lowest of the set.
| Bar | Low | Position | Check against the middle bar |
|---|---|---|---|
| 1 | 101.90 | Left side | Higher than 100.70 |
| 2 | 101.40 | Left side, nearest | Higher by 0.70 (101.40 minus 100.70) |
| 3 | 100.70 | Middle bar | Lowest of the five |
| 4 | 101.20 | Right side, nearest | Higher by 0.50 (101.20 minus 100.70) |
| 5 | 101.60 | Right side | Higher than 100.70 |
EXAMPLE values only. Bar 3 is the down fractal, and it is confirmed when bar 5 closes.
A down fractal reads the same way with the inequalities reversed. Bar 3 is the swing low at 100.70, and it is known only once bar 5 has closed.
Why a fractal is confirmed two bars late
A fractal cannot be known when its middle bar prints. To check the right-hand side, the indicator needs the two bars after the middle bar. In the up fractal EXAMPLE, bar 3 prints the high at 106.40, but the pattern is complete only when bar 5 closes. That is a lag of two bars.
TradingView describes the lag as 'two or more candlesticks, give or take', and says the Williams fractal does not redraw. Because of this, the newest two bars on any chart cannot yet form a confirmed fractal. The most recent confirmed fractal always sits at least two bars behind the current bar.
How traders use fractals to mark swing points
A confirmed fractal gives a dated swing point. Some traders record its high or low as a reference level and watch how later price behaves around it. In the up fractal EXAMPLE, the 106.40 high is the reference. A later close above 106.40 would show that the reference high has been exceeded. It would not show what happens after that.
Some traders read fractal levels alongside support and resistance, which looks at price areas that have held or failed before. A different way to filter swings is the ZigZag indicator. The Awesome Oscillator is another Bill Williams tool, and it is a separate indicator with its own rules.
- Record the time of the confirmation bar, not only the middle bar, so you know when the fractal became known.
- Treat a reference level as a description of a past high or low. It does not say where price will stop or reverse.
- Compare the fractal with the wider chart. A single fractal in a quiet range says less than a clear swing in a trend.
Variants and settings: where the references differ
The cited references agree on the middle-bar extreme and on five candlesticks as the TradingView default. They differ on the bar count the MetaTrader 5 page states, and on what they say about settings. The table records each reference as written.
| Reference | Bars per fractal | Default | Lag and redraw |
|---|---|---|---|
| MetaTrader 5 help, Fractals | At least five successive bars, middle bar extreme (MT5 wording) | Not stated on the page | Not stated on the page |
| TradingView support, Williams fractal indicator (credits Bill Williams, Trading Chaos, 1995) | Five by default, with the count adjustable | Five candlesticks | Two or more candlesticks, give or take; no redraw |
Verified on 10 November 2026. Where a reference does not state a value, the cell says so rather than filling it in.
TradingView lets users change the total candlestick count. Neither cited source says how the confirmation lag changes with a different count, so this page gives no figure. A different count draws a different set of marks on the same price data, so check the setting before you compare two charts.
Limits of the fractals indicator
A fractal describes past price. It shows that a middle bar was the highest or lowest of five bars. It does not show that price will reverse, that a level will hold or that a move will continue.
The indicator does not say how much to trade, where to place a stop loss or whether a level is worth using. A risk-reward ratio check is one way to look at a trade plan first.
Risk disclosure
- A fractal describes past price and is confirmed only after two later bars. It is not a forecast, and a confirmed fractal can be exceeded later.
- The fractals indicator does not give win rates, results or expected profit. No study result is stated on this page.
- The confirmation lag means the mark appears after the turning point. Acting on it can mean entering after a move has already started.
- A choppy range can show many fractals, and each one carries the same two-bar lag. Many marks do not mean a clearer trend.
- Platforms differ on settings and on how they handle equal highs or lows, so the same market can show different marks on different charts.
- This page is educational and is not personal financial advice. Trading can lose money, and the examples are illustrative only.

Questions readers ask
What is the fractals indicator?
The fractals indicator marks a swing high or swing low on a price chart. It uses a five-bar pattern in which the middle bar has the highest high of the set (an up fractal) or the lowest low (a down fractal). TradingView credits Bill Williams and his 1995 book Trading Chaos. It describes past price and does not predict the next move.
How many bars does a Williams fractal use?
The default Williams fractal uses five consecutive bars. The middle bar is the extreme, and two bars sit on each side. TradingView says the default is five candlesticks and that users can change the count. The MetaTrader 5 help page describes a set of at least five successive bars, so it does not fix the count at five.
Why is a fractal confirmed late?
A fractal needs the two bars to the right of the middle bar before its pattern is complete. That means it is confirmed two bars after the turning point. TradingView describes this as a lag of two or more candlesticks, give or take, and says the indicator does not redraw.
Is a fractal a buy or sell signal?
No. A fractal describes a swing point that has already formed. This guide does not present fractals as buy or sell signals and gives no win rate or result. Some traders use confirmed fractal highs and lows as reference levels, but a level being exceeded does not show which way price will move next.
Does this guide cover Bill Williams' other indicators?
No. This guide covers the fractal only. Bill Williams also developed other indicators, such as the Awesome Oscillator, which has its own guide. That guide describes how the oscillator is constructed, including the Gator. Combinations of tools are a separate topic and are not covered here. Neither page sets out a trading setup, and reading one indicator does not confirm another.
