Ichimoku Kinko Hyo
Five lines intended to be read as one picture. Every component is a midpoint of a range or a shifted copy, which is what makes the whole thing derived from the same series.

What to take away
- Five components, all computed from highs and lows rather than closes.
- The cloud is the area between two of them, projected forward.
- Forward and backward shifts are what make it look unlike other indicators.
- It is a moving-average system in different clothing.
- The default parameters come from a market that traded six days a week.

Five Lines That Answer One Question Each
Ichimoku looks impenetrable because it is five indicators drawn at once. Taken one line at a time it is straightforward.
This lesson is part of a Stock Alerts + Tools plan.
The five components
| Line | Calculation | Shift |
|---|---|---|
| Conversion line | Midpoint of the 9-period high and low | None |
| Base line | Midpoint of the 26-period high and low | None |
| Leading span A | Midpoint of the two lines above | Forward 26 periods |
| Leading span B | Midpoint of the 52-period high and low | Forward 26 periods |
| Lagging span | The close | Backward 26 periods |
Every one is a midpoint of a high-low range over a window, which is a form of moving average that uses extremes rather than closes. The cloud is the region between the two leading spans.
What the shifts do
The forward shift is what gives the chart its distinctive appearance: the cloud extends to the right of the current bar, into space where no price exists yet. It is not a forecast. It is a value computed from past data and drawn twenty-six periods to the right.
This is the most common misreading of the system. The cloud ahead of price was computed from prices that have already occurred, and it will not change as new bars arrive. Reading it as a projection reads a shifted average as a prediction.
The backward-shifted lagging span is the same trick in reverse: today's close, drawn twenty-six periods back, so that it can be compared against where price was then.
Reading it
- Price above the cloud is conventionally read as an uptrend, below as a downtrend, and inside as no trend.
- The conversion line crossing the base line is a faster signal, equivalent to a short average crossing a longer one.
- The cloud's thickness reflects the distance between two averages, which is a measure of how much the trend has changed recently.
- The lagging span above the price from twenty-six periods ago is a confirmation of the same trend condition.
Read as a list, the system is a set of moving-average relationships with a shifted envelope. Nothing in it uses information the price series does not contain, and the components agreeing is arithmetic rather than corroboration.
The parameters
The values 9, 26 and 52 come from a period when Japanese markets traded six days a week: roughly a week and a half, a month, and two months. On a five-day week they correspond to nothing in particular, and they have been carried forward unchanged.
That is not an argument against them. It is the same observation the MACD article makes about 12, 26 and 9: the defaults are conventions with a historical origin, and their main virtue now is that a great many people use them.

What it adds over a moving average system
Since every component is a midpoint of a range, it is fair to ask what the system provides that two moving averages do not. There are two answers and both are modest.
| Feature | What it genuinely adds |
|---|---|
| Midpoints of highs and lows | Uses the full range rather than closes, so gaps and wicks enter |
| The cloud as a zone | A band rather than a line, so the trend condition has a width |
| The forward shift | Nothing predictive. It repositions past values on the axis |
| The lagging span | A single comparison against price 26 periods ago |
The first two are real. Using the full range rather than closes is a genuine difference in construction, and a zone rather than a line means the trend condition is not decided by a single crossing.
The third row is where most of the system's mystique sits and it is arithmetic. Drawing a computed value twenty-six periods to the right makes a chart look forward-looking and adds no information to it.
