Ichimoku Cloud

Overview

Ichimoku Kinko Hyo (一目均衡表) — literally “one-glance equilibrium chart” — was developed by Japanese journalist Goichi Hosoda in the 1930s and published in 1969. It combines trend direction, momentum, and support/resistance into a single visual system. Despite its visual complexity, it’s designed to be readable at a glance once you know what you’re looking at.

The indicator has five components:

• Tenkan-sen (Conversion Line) — short-term momentum
• Kijun-sen (Base Line) — medium-term momentum / dynamic support
• Senkou Span A — leading edge of the cloud
• Senkou Span B — other edge of the cloud
• Chikou Span (Lagging Span) — current price plotted 26 periods back

The “cloud” (Kumo) is the shaded area between Senkou Span A and B, projected 26 periods into the future.

Formula

Tenkan-sen   = (9-period High + 9-period Low) / 2
Kijun-sen    = (26-period High + 26-period Low) / 2
Senkou Span A = (Tenkan-sen + Kijun-sen) / 2, plotted 26 periods ahead
Senkou Span B = (52-period High + 52-period Low) / 2, plotted 26 periods ahead
Chikou Span   = current close, plotted 26 periods back

Default Settings

• Tenkan period: 9
• Kijun period: 26
• Senkou Span B period: 52
• Displacement: 26

These reflect Japanese business calendar (10-day weeks). Some traders adapt to (7, 22, 44, 22) for modern 5-day market weeks.

How to Use It

1. Cloud as Trend Filter

The single most important read:

• Price above the cloud → uptrend
• Price below the cloud → downtrend
• Price inside the cloud → sideways / no clear trend (avoid trading)

The cloud’s thickness indicates trend strength — thick cloud = strong trend regime, thin cloud = weak / transitioning.

2. Cloud Color (Bullish / Bearish)

• Senkou A above Senkou B (cloud green / blue) → bullish
• Senkou A below Senkou B (cloud red) → bearish

A color change in the future projection (where the cloud flips) is an early warning of trend regime change.

3. Tenkan / Kijun Crossover

Similar to MACD signal-line crossover but using midpoints of price highs/lows:

• Tenkan crosses above Kijun → bullish
• Tenkan crosses below Kijun → bearish

Higher-quality signal when the cross happens above (bullish) or below (bearish) the cloud.

4. Chikou Span Confirmation

The Lagging Span confirms trend strength:

• Chikou above price 26 periods ago → bullish confirmation
• Chikou below price 26 periods ago → bearish confirmation

Many Ichimoku purists require Chikou confirmation before entering a trade.

5. The Perfect Setup

The classic strong-trend Ichimoku signal requires ALL of:

1. Price above (or below) the cloud
2. Tenkan crosses Kijun in trend direction
3. Cloud color matches trend direction (green for long, red for short)
4. Chikou Span on the trend-confirming side of price

Strengths

• All-in-one — trend, momentum, support/resistance and forward projection on a single chart
• Self-contained — doesn’t require additional indicators in many cases
• Cloud projects future support/resistance levels, unique among indicators
• Forces holistic reading of market state rather than single-line signals

Weaknesses & Common Mistakes

• Visually overwhelming — new traders give up before learning to read it
• Lagging — designed for sustained trends, not short-term scalping
• Underperforms in ranges — when price chops inside the cloud, signals conflict
• Trading one signal alone — e.g. Tenkan/Kijun cross without cloud confirmation produces many false signals

Best Combinations

• Ichimoku + RSI — Ichimoku defines trend, RSI provides momentum / divergence within that trend
• Ichimoku + Higher Timeframe Confirmation — check daily Ichimoku trend before taking H4 entries
• Ichimoku alone — many practitioners use Ichimoku as a complete standalone system, avoiding indicator stacking

Practical Example

USD/JPY daily chart. Price has been above the cloud for two months (uptrend). Pullback brings price down to the Kijun-sen, which has flattened. Bullish engulfing forms at Kijun. Cloud ahead is green and rising. Long entry, stop below the Kijun, take profit at recent swing high. The Kijun acted as dynamic support — one of Ichimoku’s most reliable plays.

Bottom Line

Ichimoku looks complicated for the first week, then suddenly clicks. After it does, you may find it’s the only indicator you need.
