Demystifying the Ichimoku Cloud

Still growing amongst the Western and European traders, the Ichimoku Cloud (or Ichimoku Kinko Hyo = One Glance Balance Cloud Chart) was originally developed pre-WWII by a man named Goichi Hosada. Because of the war, his research was halted and then later finished in 1968 whereby he published a 1,000 page, four volume body of work releasing the Ichimoku Cloud to the world under the pen name Ichimoku Sanjin.

Originally built for the Japanese stock markets, the indicator has made its way out of the land of the Eastern sun and into the trading world at large, being applied and used widely in the Commodities, Futures, Options and FOREX markets. Part of its success is its ability to find trends and reversals well before they begin.

The Indicator
The Ichimoku Cloud has several components that give it a lot of versatility and uses. The most unique aspect of the indicator is its ‘Kumo’ or cloud, which offers a unique perspective of support and resistance. Most western methods look at support and resistance in a linear fashion or as straight lines in the sand (e.g. Fibonacci, Pivots, Channel Lines, and Trend Lines). However the Kumo or cloud is an ever-evolving object that was designed to represent support and resistance based upon price action. Generally, when you are in a strong upward trend, the support is strong as the price levels below have been accepted. The same goes for a strong downtrend and having more layers of resistance. Below are two examples of up and downtrends – showing how the Kumo was quite thick in nature.

The most important way to look at the Kumo is as support and resistance – meaning if it is thick, then the support/resistance (depending upon where price is in relationship to the cloud) is strong. If price is above the Kumo, we are in a general uptrend or would want to look for more buying opportunities. If price is below the cloud, it is below resistance (the Kumo) and we want to be searching for more shorts than longs. The longer price stays below/above the cloud, the stronger the trend we are in and the more support/resistance the Kumo will offer.

Kumo Composition
There are two main lines of the Kumo, which are referred to as Senkou Span A and Senkou Span B. For the purposes of efficiency, we will refer to them as Span A and Span B. The space, or value, in between these two lines is what forms the Kumo.

Span A is formed by taking the Tenkan Line and adding it to the Kijun Line (white and red lines respectively from chart above), then dividing that value by 2 and plotting it 26 periods ahead. The formula is:

(Tenkan Line + Kijun Line) / 2 placed 26 periods ahead.

Span B is formed by taking the highest high (over the last 52 periods), adding to it the lowest low (over the last 52 periods), dividing that by 2 and plotting that 26 time periods ahead. The formula is:

(Highest High + Lowest Low for the last 52 periods) / 2 and plotted 26 time periods ahead.

We will talk about some important points regarding the construction of the Kumo later.

Other Ichimoku Components (Tenkan, Kijun and Chikou Span Lines)
The Tenkan Line or Tenkan Sen (Sen is Japanese for line) is known as the conversion line or turning line, and is similar to a 9SMA but actually is quite different. Remember a SMA (simple moving average) will smooth out all the data and make it equal but the Tenkan Line will take the highest high and lowest low over the last 9 periods. The explanation for this is Hosada felt price action and its extremes were more important than smoothing any data because price action represented where buyers/sellers entered and directed the market, thus being more important than averaging or smoothing the data out. As you can see by the chart below, the Tenkan Line is quite different than a 9SMA. Because the TL (Tenkan Line) uses price instead of an averaging or the closing prices, it mirrors price better and is more representative of it. You can see this when the TL flattens in small portions to move with price and its moments of ranging.

Akin to all moving averages, the angle of the Tenkan line is very important as the sharper the angle, the stronger the trend while the flatter the Tenkan, the flatter or lesser the momentum of the move is. However, it is important to not use the Tenkan line as a gauge of the trend but more so the momentum of the move. However, it can act as the first line of defence in a trend and a breaking of it in the opposite direction of the move can often be a sign of the defences weakening.

The Kijun Line (or Kijun Sen) is known as the datum line, standard line or trend line designed to indicate the overall trend for the instrument or pair. The formula behind it is the same as the Tenkan line using price action and the highest high + lowest low with the only change being in the periods as it does it over the last 26 periods.

Why 26 periods? The answer to that is a matter of history. When the Ichimoku was first created, the Japanese markets were open 6 days a week (including Saturdays). If the markets are open 6 days a week, this generally results in 26 trading days for the month – hence 26 periods for the Kijun. In essence, what it was meant to be was a measure of the highest high + lowest low for the last month of price action. If the Kijun has been climbing – it means price has been gaining ground for the last month. If it is flat, then it will be the midpoint of the range of price for the last month of price action (or representative of the price equilibrium).

Also like the Tenkan Line, the angle of the Kijun is reflective of the overall trend in place. Price breaking the Kijun after being in an up/down trend often has serious consequences for that trend and can many times lead to a reversal of sorts. Ultimately because it uses a longer period to measure price action, its a more stable method for determining the direction of the trend than the Tenkan Line. Because of price to respect this line during a strong trend, it can potentially be used as a stop loss for traders already in the correct direction of the trend. Hence, when price breaks or closes below it by a significant amount, the trend is often over.

The Chikou Span or lagging line is created by taking the current closing price for the instrument and shifted 26 time periods back, hence why it is a lagging line. This is a strange concept and not something usually seen in technical indicators, which makes the Ichimoku Cloud even more unique. The purpose is simply to gain perspective in regards to how the current price action is in relationship to previous price action.

The main application for giving perspective to the trader is how does the Chikou Span relate to price 26 periods ago? If the Chikou Span is lower than price 26 periods ago, then there is resistance for the current up move or pressure that could force price down into a bearish move. However if the Chikou Span is above price from 26 periods ago, then it would mean there is little or no resistance ahead since price is in the process of making new highs and there is no recent price above it – thus paving the way for a strong trend.

Applications for the Tenkan and Kijun
The most common usage of the Tenkan and Kijun are the ‘cross’ or what we call the TKx (Tenkan-Kijun Cross). Similar to how a MACD uses a cross of its two lines, the Ichimoku Cloud does the same. It is interesting to note that the Ichimoku uses the same periods as the MACD, however it was created over a decade earlier.

One of the main signals for Ichimoku traders, the TKx can often indicate when a trend is about to begin by forming a cross (upward cross = possible upward trend while downward cross = possible down trend). A generic upward cross can be used as a bullish signal (or exit for people already short) and a generic downward cross can be used as a generic bearish signal (and vice versa for current bulls). However, notice we used the term ‘generic,’ meaning there is more to the cross.

Hosada was able to give a further definition to the cross based upon its position to the Kumo or cloud. If the cross was below the Kumo, then it was considered a ‘weak’ signal since the cross was below the Kumo or below resistance. A medium signal was when a cross happened inside the Kumo as it was occurring within the field of support/resistance. A strong signal was when the bullish cross happened above the Kumo as it was happening after clearing resistance. The opposite is true for bearish signals whereby a weak signal is a cross above the Kumo, while a medium signal is inside the Kumo and a strong signal below the Kumo. One important reminder to all this is to make sure you reference the Chikou Span to see how current price is in relationship to previous price action.

The nature of the cross usually indicates the overall strength or potential for the move but it should be noted strong trends have developed from weak crosses. It is always also important you reference the construction of the Kumo when trading the typical TKx signals.

Some Important Final Notes on the Kumo
As stated previously, the Kumo is designed to represent support and resistance but it has a host of implications in doing such. To review, the thicker the Kumo, the stronger the support/resistance it will offer. Price will often reject off of the Kumo only to resume the current trend as depicted below by a few examples.

What this also means is if the Kumo is exceptionally thin, in a ranging market it likely means the range will continue as there is neither enough support nor resistance to hold a single direction for the pair. What it also means is if we are in a current trend and price is approaching a thin Kumo, the chances increase for a trend reversal since the support/resistance offered by the Kumo is not significant. This is why Kumo analysis is important as it can often lead to reversals and inform us in the future of pending trend changes.

Also, there is a common formation in the Kumo called the ‘flat top or bottom’. This refers to when the Span B becomes flat. Remember the Span B is composed of the last 52 candles absolute highest high and lowest low – thus referring to price action over the last 52 periods. If Span B is flat, the only way it can do that is if price has not extended to make any new significant highs or lows. This means we are in a range and the tendency of a range is to move towards equilibrium or towards the center of the range – also known as the value area for price. The end result is, during a ranging environment, the Span B is the virtual 50% Fibonacci retracement level for that range and is the ever-changing 50% Fib level for a trending environment, dividing the last 52 candles into two halves, the upper and lower half.

What does this mean for traders? If price is inside the Kumo, it will have a tendency to gravitate toward the flat top/bottom. If price is above it, the tendency of price will be to gravitate toward the flat top/bottom, often using it as a springboard for a rejection off of it.

Lastly, one of the most important things about the Kumo is what happens when price breaks it. If we have been in a strong trend for some time and price then breaks the Kumo, it usually represents a trend change and the likelihood of a large move about to begin in the direction of the break as you can see by the examples below.

It is because the Kumo is always changing shape that it can represent a much better perspective of support and resistance. It is essentially based upon price action and changing shape based upon previous price moves. This makes it a little more sensitive and representational to price unlike static forms of support and resistance (Fibonacci Retracement Levels, Pivots, Trend Lines, etc.), which do not move at all once they are in place. It is its unique construction that allows the Kumo to be both static and dynamic in giving support/resistance levels to the trader.

In Closing
This is just the beginning of the Ichimoku Cloud and designed to give the trader an introduction to the key elements around such a fascinating indicator and method for trading the markets. The Ichimoku Cloud has the ability to detect trends, reversals, support/resistance levels, trend strength/weakness and momentum for a pair. It is due to its ability to be used in multiple environments, along with its unique perspective upon price and support/resistance levels that Institutional and retail traders have gravitated toward using this method.

I squinted my eyes to view those charts. Still I could not view it properly. Can't you publish charts in white background? Should your readers suffer and strain that much harder and more to see the charts as well? What is the use of article if one cannot view the charts associated with it?
Hello RSI,

You may want to bring this up with the site administrator as they determine the size of the charts. The original resolution is well over 1200 x 700 which is plenty but my guess is they had to reduce it significantly to fit the site.

However, all of the charts have a 'click to enlarge' option which after clicking on them, they become much more readable.

Hope this helps,

Great course!!

This is a quite enlightening and useful post. I have read it and to my surprise realize that this is what I have been looking for. It is fantastic. Despite the low resolution for the charts, the article clearly defines what the Ichimoku cloud entails in simple and clear terms. I also like the clarification on the components of the cloud and how a trader can use the indicator to identify favorable market positions in appropriate time frame. For sure one can make money with the Ichimoku. Blended with the
in your site I am not what I used to be.. I would lie if I told you that I have captured everything from the article; hence, would like to get more about the Ichimoku cloud from you Chris.
