Ichimoku Cloud (Ichimoku Kinko Hyo)

A multi-line system that aims to show trend direction, equilibrium, and potential support/resistance on a single chart.

What it is

Ichimoku Cloud, or Ichimoku Kinko Hyo ("one-glance equilibrium chart"), is a trend-following framework developed by Japanese journalist Goichi Hosoda and his team, refined over decades and published in its complete form in 1969. Rather than a single line, it combines five components: the Tenkan-sen (conversion line), Kijun-sen (base line), Senkou Span A and Senkou Span B (which together form the "cloud," or Kumo), and the Chikou Span (lagging line). The shaded area between the two Senkou spans is the cloud that gives the indicator its name. It is designed to convey trend, equilibrium, and potential support/resistance zones at a glance. Like all indicators, it is descriptive rather than predictive: it summarizes past and current price and offers no guarantee of future price behaviour. All trading carries risk of loss.

How it works

Each line is a straightforward calculation based on highs and lows over set lookback periods (defaults 9, 26, 52). The Tenkan-sen is the midpoint of the highest high and lowest low over the last 9 periods; the Kijun-sen is that same midpoint over 26 periods. Senkou Span A is the average of the Tenkan and Kijun lines, plotted 26 periods into the future. Senkou Span B is the 52-period midpoint, also plotted 26 periods ahead. The space between Spans A and B forms the cloud. The Chikou Span is simply the current closing price plotted 26 periods back in time. The forward shift of the cloud and the backward shift of the Chikou are central to how the system is read.

How traders read it

• Price above the cloud is often read as a broadly bullish context, price below as broadly bearish, and price inside the cloud as a zone of indecision or consolidation.
• Traders often watch crossovers of the Tenkan-sen and Kijun-sen: the faster Tenkan crossing above the slower Kijun is commonly read as building upside momentum, and the reverse as building downside momentum.
• The cloud itself is frequently treated as a dynamic support/resistance area; a thicker cloud is often interpreted as a stronger potential barrier and a thinner cloud as a weaker one.
• The colour of the cloud (Span A above or below Span B) is used as a rough gauge of the prevailing trend bias projected ahead.
• The Chikou Span is often compared with past price: when it sits above the price from 26 periods ago, some traders read this as leaning to the upside, and the opposite as leaning to the downside.
• Many traders treat a setup as more notable only when several components agree, rather than reading any single line in isolation. None of these readings is predictive, and all trading carries risk of loss.

Common settings

Classic settings are Tenkan 9, Kijun 26, Senkou Span B 52, with both cloud spans displaced 26 periods forward and the Chikou Span displaced 26 periods back. Some traders adapt these for 24-hour or higher-timeframe markets, for example by doubling the values (roughly 20/60/120), but the original 9/26/52 remains the most widely used baseline. Any change alters every line, so it should be tested rather than assumed to be an improvement.

Strengths

• Brings trend context, momentum cues, and potential support/resistance into one self-contained view.
• Plotting the cloud forward gives a visual reference for potential support/resistance zones ahead of price.
• Multiple components let traders look for confluence rather than relying on a single line.
• Works on any timeframe and instrument, since it is based only on price highs and lows.

Pitfalls to watch

• The indicator is lagging by construction: lines are built from past highs and lows, and the forward-shifted cloud is derived from older data, so signals can appear after a move is already underway.
• In ranging or choppy markets the lines can whipsaw and produce frequent conflicting readings, which traders often describe as false signals.
• The chart can look cluttered for beginners; five lines plus a cloud spanning past, present, and future make it easy to misread.
• The default settings (9/26/52) come from a different market era and instrument and are not universally suitable; changing them changes every line and reading.
• Because the cloud and Chikou are shifted in time, the most recent plotted values can change as new bars form. Reading closed bars rather than reacting to an unfinished bar helps avoid acting on values that are still moving.

Pine v6 example

//@version=6
indicator("Ichimoku Cloud", overlay = true)

tenkanLen  = input.int(9, "Tenkan")
kijunLen   = input.int(26, "Kijun")
senkouBLen = input.int(52, "Senkou B")
disp       = input.int(26, "Displacement")

midpoint(simple int len) => math.avg(ta.highest(high, len), ta.lowest(low, len))

tenkan  = midpoint(tenkanLen)
kijun   = midpoint(kijunLen)
senkouA = math.avg(tenkan, kijun)
senkouB = midpoint(senkouBLen)

plot(tenkan, "Tenkan-sen", color = color.blue)
plot(kijun,  "Kijun-sen",  color = color.red)
plot(close,  "Chikou Span", color = color.green, offset = -disp)

spanA = plot(senkouA, "Senkou A", color = color.teal,   offset = disp)
spanB = plot(senkouB, "Senkou B", color = color.orange, offset = disp)
fill(spanA, spanB, color = senkouA > senkouB ? color.new(color.teal, 80) : color.new(color.orange, 80), title = "Kumo")

Pro tip: A common workflow is to use the cloud for context (which side of it price is on) and then look at the Tenkan/Kijun relationship and the Chikou for confirmation, rather than reading any one line alone. Confirming on closed bars and across more than one component can reduce reaction to noise, but it removes neither the indicator's lag nor the risk of loss. This is educational, not advice.
