Ichimoku Cloud for Beginners: The Five Lines Explained
The Ichimoku cloud uses five lines to show trend, momentum and support zones at a glance. Learn each formula, how to read the cloud and where it fails.
The first time you add Ichimoku to a chart, it looks like someone spilled five colours of ink across the candles. Once you know what each line measures, it reads as a fairly simple summary of the recent highs and lows.
Quick answer: The Ichimoku cloud is a set of five lines built from the midpoints of recent highs and lows: Tenkan-sen (9 periods), Kijun-sen (26), Senkou Span A and B (shifted 26 periods ahead, forming the cloud) and the Chikou Span (the close shifted 26 back). Price above the cloud suggests an uptrend; below it, a downtrend; inside it, no clear trend.
What is the Ichimoku cloud?
Ichimoku Kinko Hyo, usually shortened to Ichimoku, was developed in Japan by Goichi Hosoda, a newspaper journalist who wrote under the pen name Ichimoku Sanjin. He worked on it from the late 1930s, with assistants doing the calculations by hand, and published it in a series of books in 1969. The name means roughly “equilibrium chart at one glance”. The goal was a single view that shows the trend, its strength and the nearby support and resistance without switching between tools.
It is an indicator in the usual sense: every line is calculated from past prices, so every line lags. What makes it different from a moving average is the raw material. Most Ichimoku lines are midpoints of a range: the highest high plus the lowest low over a period, divided by two. They describe where the middle of the recent price range sits, not the average close.
The full system Hosoda described also includes time cycles and wave counts that most charting platforms do not display. This guide covers the five lines that platforms do show, which is what traders usually mean by “the Ichimoku cloud”. The Academy’s new Technical Indicators in Depth course has a full lesson on the Ichimoku cloud, and if indicators are new to you, start with the lesson on indicators.
The five lines and their formulas
Each line answers a slightly different question. Here they are with the standard settings, which are usually written as 9, 26, 52.
Tenkan-sen (conversion line): the midpoint of the last 9 periods.
Tenkan-sen = (highest high of 9 periods + lowest low of 9 periods) ÷ 2
Kijun-sen (base line): the midpoint of the last 26 periods.
Kijun-sen = (highest high of 26 periods + lowest low of 26 periods) ÷ 2
Senkou Span A (leading span A): the average of the first two lines, drawn 26 periods ahead.
Senkou Span A = (Tenkan-sen + Kijun-sen) ÷ 2, plotted 26 periods forward
Senkou Span B (leading span B): the midpoint of the last 52 periods, drawn 26 periods ahead.
Senkou Span B = (highest high of 52 periods + lowest low of 52 periods) ÷ 2, plotted 26 periods forward
Chikou Span (lagging span): today’s close, drawn 26 periods back.
The space between Senkou Span A and Senkou Span B is shaded, and that shaded band is the cloud, or kumo. When Span A is above Span B, the cloud is usually coloured as bullish; when Span A is below Span B, bearish.
Midpoints, not averages
The midpoint behaves differently from an average, and it explains a lot about how Ichimoku looks on a chart. A 9-period moving average changes with every new close. The Tenkan-sen changes only when a new highest high or lowest low enters the 9-period window, or an old one drops out. Between those moments it is perfectly flat.
The flat stretches are useful. A flat Kijun-sen means the 26-period range has not changed: price has been moving inside an established high and low. Many Ichimoku traders read a flat Kijun-sen as a level that price tends to return to, which is another way of saying the middle of a range.
The 26-period shifts
Two of the five lines are drawn away from the candle they were calculated on, and this trips up most beginners.
The cloud you see under today’s candle was therefore calculated 26 periods ago, from the data available then. The cloud drawn to the right of today, over empty space, was calculated from today’s data. It is not a forecast; it is today’s midpoints, displaced so that you can compare them with future prices as they arrive.
The Chikou Span works the other way. It takes today’s close and draws it 26 periods back, so you can see at a glance whether today’s price is above or below where price was 26 periods ago. It is simply a momentum check presented as a line. Platforms differ by one candle in how they count the shift, because some include the current candle in the 26, so do not be surprised if two charts disagree slightly.
How to read the Ichimoku cloud
The cloud is read first, because it gives the broad picture.
- Price above the cloud: the bias is bullish. The cloud below acts as a support zone.
- Price below the cloud: the bias is bearish. The cloud above acts as a resistance zone.
- Price inside the cloud: there is no clear trend. Ichimoku traders usually stand aside here.
The cloud’s thickness matters too. A thick cloud means the two spans are far apart, usually because the 52-period range is wide. It is a wide zone of potential support or resistance. A thin cloud is a narrow zone that price can break through easily. The point where Span A and Span B cross is called a twist, and the cloud changes colour there. Because the cloud is drawn 26 periods ahead, a twist on the right side of the chart tells you that the balance of the recent midpoints has already shifted.
Then come the lines:
- Tenkan-sen above Kijun-sen means the 9-period midpoint is above the 26-period midpoint: short-term prices are higher in their range than the longer-term ones. A TK cross is the moment the two lines cross.
- Price relative to the Kijun-sen is a simple trend filter. In an uptrend, price usually stays above it, and pullbacks often stall near it.
- The Chikou Span above the price of 26 periods ago confirms that price is higher now than it was then.
Ichimoku traders often look for these readings to line up. A commonly taught bullish setup has price above the cloud, a bullish TK cross above the cloud, a green cloud ahead and the Chikou Span above past prices. The same cross below the cloud is treated as weak, and inside the cloud as neutral. None of these combinations makes the outcome certain, and agreement between five lines built from the same highs and lows is still one source of information, a point the lesson on combining indicators makes in detail.
The ideas will feel familiar if you have used moving averages or price structure. The cloud plays the role of a slow average with a width; the TK cross plays the role of a fast-slow crossover. Our guide to how to identify a trend shows the price-only version of the same judgement, and it is worth checking that the cloud agrees with what the swing highs and lows already say.
Using Ichimoku in a trade plan
Ichimoku does not give you a complete plan on its own, but it does supply levels for one. Here is one common way to use it in an uptrend, stepped through on candles. The stop is the part to study: Ichimoku levels on a daily chart are often far from price.
Illustrative EUR/USD daily candles. Price is above the cloud and pulls back to the Kijun-sen, a common Ichimoku entry area. The stop below the cloud is 88 pips away, so the position has to be small.
The arithmetic matters more than the setup. With a $5,000 account and 1% risk, the budget is $50. A stop 88 pips away allows $50 ÷ (88 × $10) = 0.057 lots, rounded down to 0.05 lots, risking 88 × $0.50 = $44. A trader who sets the size first and the stop second ends up with either a stop inside the noise or far too much at risk. Ichimoku’s wide levels make that mistake more expensive. Our guide to support and resistance covers how to judge whether a zone is worth defending, and the guide to trailing stops covers exits that move with the trend, as the Kijun-sen does.
Leverage magnifies these numbers in both directions. A wide stop on a small position and a narrow stop on a large one can risk the same money, but only if you do the calculation every time. The lesson on trend following shows how trend tools like this one fit into a tested plan with a fixed risk per trade.
Where the Ichimoku settings come from, and should you change them?
The numbers 9, 26 and 52 come from the calendar Hosoda worked with. Japanese markets traded six days a week at the time, with Saturday a trading day, and Japanese exchanges kept Saturday sessions until the late 1980s. On a six-day week:
- 9 trading days is a week and a half.
- 26 trading days is about one month (a 30-day month minus four Sundays).
- 52 trading days is about two months.
Forex trades five days a week, and that has started a long-running debate.
The case for changing them. If the settings were meant to capture a week and a half, a month and two months, then on a five-day week the matching numbers are roughly 7 or 8, 22 and 44. Some traders use 7, 22, 44 for that reason. In markets that trade seven days a week, such as cryptocurrencies, people have tried longer settings for the same logic.
The case for keeping them. The standard settings are what almost every platform, book and Ichimoku trader uses, so the levels on your chart are the levels others are watching. Hosoda is said to have tested his numbers extensively, and some practitioners argue they reflect his wider theories of time cycles rather than the calendar alone. And on intraday charts the calendar logic disappears anyway: 26 one-hour candles are not a month of anything.
There is no good evidence that any variant works better across markets. The bigger danger is the usual one with indicator settings: trying combinations until one fits the last year, then watching it stop working. We suggest you learn on the standard 9, 26, 52, test any change over many trades, and change only one thing at a time.
Where Ichimoku struggles: ranges, lag and wide stops
Ichimoku is a trend tool. When the market is trending, the cloud, the Kijun-sen and the Chikou Span tend to agree, and the picture is clear. When the market moves sideways, the same lines turn into noise.
In a range, three things happen at once. The Tenkan-sen and Kijun-sen flatten and cross repeatedly, because the 9-period and 26-period midpoints are almost the same. The cloud thins and twists, because Span A and Span B converge. And price drifts in and out of the cloud, so “above” and “below” change every few days. A trader who takes every TK cross in that environment pays the spread and the stop again and again. The honest reading of a flat, thin, twisting cloud is “no trend”, which means Ichimoku has little to add and range tools, covered in our guide to range trading, are more suitable.
Here is the situation as a decision. Price has been crossing a thin cloud for weeks, and a fresh bullish TK cross has just appeared.
EUR/USD has moved between about 1.0825 and 1.0880 for a month. The cloud is thin and has changed colour twice, and the Tenkan-sen has just crossed above the Kijun-sen again. What would you do?
Illustrative EUR/USD prices in a sideways month. A fresh bullish TK cross near the top of the range, then the rest of the chart. The cross failed, as crosses often do when the cloud is thin and twisting.
Two further limits apply in every market. The first is lag. The Kijun-sen uses a 26-period range and Senkou Span B a 52-period one, so the cloud reacts slowly to a change of trend. By the time price has crossed a thick cloud, a large part of the reversal may be over.
The second is distance. On a daily chart the cloud can sit 100 pips or more from price. A stop placed beyond it is a wide stop, and a wide stop needs a small position. The lesson on support and resistance shows how to choose a nearer level that still proves the idea wrong.
There is also a small forex-specific quirk. The market trades around the clock, so the daily candle depends on your platform’s server time. Daily highs and lows, and therefore every midpoint, can differ slightly between platforms. Ichimoku is popular on yen pairs, partly because of its Japanese origin; USD/JPY is among the most traded pairs in the world according to the BIS Triennial Survey, and our USD/JPY trading guide covers what moves it. The indicator works the same way on every pair; it has no special accuracy on the yen.
Common Ichimoku mistakes
Treating the future cloud as a forecast
The cloud to the right of today is today’s midpoints shifted forward. It shows where recent support and resistance would sit if nothing changes. It does not predict where price will go.
Taking TK crosses inside or under the cloud
A bullish cross below the cloud, or inside it, is the weakest version of the signal. In a range, crosses come in clusters. Check where price is relative to the cloud before reading a cross.
Counting five agreeing lines as five reasons
All five lines come from the same highs, lows and closes. When they agree, you have one view of the trend, drawn five ways. Add evidence from elsewhere, such as a level or the higher-timeframe trend.
Placing the stop inside the cloud without sizing for it
A stop beyond the cloud is often 80 to 150 pips away on a daily chart. Calculate the position size from that distance; if the size is too small to be worth trading, skip the trade or find a nearer level.
Changing the settings to fit recent prices
Switching between 9, 26, 52 and other combinations until the chart looks right is curve fitting. Learn on the standard settings and judge any change over a large number of trades.
Frequently asked questions
What does the Ichimoku cloud tell you?
It shows the trend bias and nearby support or resistance. Price above the cloud suggests an uptrend, below it a downtrend, and inside it no clear trend. The cloud's thickness shows how wide the support or resistance zone is. It is built from past highs and lows, so it describes the market rather than predicting it.
What are the five lines of Ichimoku?
Tenkan-sen is the 9-period midpoint of highs and lows. Kijun-sen is the 26-period midpoint. Senkou Span A averages those two and is drawn 26 periods ahead. Senkou Span B is the 52-period midpoint, also drawn 26 ahead. The Chikou Span is the close drawn 26 periods back. The two Senkou spans form the cloud.
Should I change the Ichimoku settings for forex?
Some traders use 7, 22, 44 because forex trades five days a week, while the standard 9, 26, 52 came from a six-day week. There is no good evidence that either works better. The standard settings are what most platforms and traders use, so they are a sensible starting point. Test any change over many trades.
What is a TK cross?
A TK cross is when the Tenkan-sen crosses the Kijun-sen. A bullish cross is the Tenkan-sen moving above the Kijun-sen; a bearish one is the reverse. Crosses above the cloud for bullish signals, or below it for bearish ones, are usually treated as stronger. Inside a range, crosses happen often and many fail.
Does Ichimoku work on short timeframes?
The calculations work on any timeframe, but the calendar logic behind 9, 26 and 52 disappears on intraday charts, and signals become more frequent and noisier. Many Ichimoku traders prefer 4-hour and daily charts. Whatever the timeframe, the cloud can sit far from price, so size each position from the stop distance.
