Ichimoku Cloud: A First Look
The cloud above today's candle was calculated 26 bars ago and shifted right. It is old information, not a forecast.
The Ichimoku Cloud is five lines, four of which are midpoints between the highest high and lowest low over 9, 26 and 52 periods. The cloud is the shaded area between two of those midpoints, both plotted 26 periods into the future. Price above the cloud is read as a bullish context, below it bearish and inside it undecided. Because the cloud is projected forward from past data, its levels are fixed well before price reaches them.
What to remember
- Tenkan and Kijun are midpoints of the extremes, not means of the closes. They ignore where price spent its time inside the lookback entirely.
- The cloud is drawn 26 periods ahead of the bar that produced it, so next week's cloud boundary is already visible today.
- A thin cloud means the 9, 26 and 52-period midpoints agree, which usually means the market has gone nowhere.
- Use the cloud alone first. Five lines used at once produce contradictions that take practice to resolve.
Lesson 9 of 22 in Trading indicators
Every line is a midpoint of a high and a low
Ichimoku looks complicated because five lines arrive at once. The calculation is not complicated. Four of the five lines are the same operation applied over different lookbacks: take the highest high and the lowest low over N periods and plot the point halfway between them. That is it.
- Tenkan-sen, the conversion line, is the midpoint of the last 9 periods.
- Kijun-sen, the base line, is the midpoint of the last 26 periods.
- Senkou Span A is the midpoint of Tenkan and Kijun, plotted 26 periods into the future.
- Senkou Span B is the midpoint of the last 52 periods, also plotted 26 periods forward.
- Chikou Span is simply the current close, plotted 26 periods into the past.
The cloud, or kumo, is the shaded area between Span A and Span B. Everything visually distinctive about this indicator comes from those two forward projections.
Computing Tenkan and Kijun on EUR/USD
Take a 4-hour chart. Over the last 9 bars the highest high is 1.0920 and the lowest low is 1.0860, so Tenkan-sen is (1.0920 + 1.0860) / 2, which is 1.0890. Over the last 26 bars the highest high is 1.0950 and the lowest low is 1.0780, so Kijun-sen is 1.0865.
Span A is the midpoint of those two, 1.08775, and it is drawn 26 bars to the right of the current candle. Span B needs the 52-bar extremes: say 1.0980 and 1.0740, giving 1.0860, also drawn 26 bars right. The cloud between 1.0860 and 1.08775 is therefore a band about 18 pips thick, sitting in space where price has not yet traded.
Two things follow from that arithmetic and are worth holding on to. A midpoint of the last 26 bars ignores where price spent its time inside that window entirely, so Kijun sits at 1.0865 whether price spent 25 of those bars at the high or at the low. And a thin cloud is thin because Span A and Span B are close together, which happens when the 9, 26 and 52-bar midpoints agree, which is another way of saying the market has been going nowhere.
