Ichimoku Cloud Explained for Automated Trading

The Ichimoku Cloud (Ichimoku Kinko Hyo) looks complex but packs trend, momentum, and support/resistance into one view. Setup.Cash supports the full Ichimoku system. This guide breaks it down.

The Five Lines

1. Tenkan-sen (Conversion, ~9): a fast midline; short-term momentum.
2. Kijun-sen (Base, ~26): a slower midline; medium-term trend and a baseline for stops.
3. Senkou Span A: average of Tenkan and Kijun, plotted ahead.
4. Senkou Span B (~52): a slow midline plotted ahead.
5. The Cloud (Kumo): the area between Span A and Span B — the heart of the system.

How to Read the Cloud

• Price above the cloud: uptrend. The cloud acts as support.
• Price below the cloud: downtrend. The cloud acts as resistance.
• Price inside the cloud: no clear trend — avoid or trade cautiously.
• Thick cloud: strong, stable trend. Thin cloud: weak, easily broken.

Core Signals

Tenkan/Kijun cross. Tenkan crossing above Kijun is bullish; below is bearish. Stronger when it happens above the cloud (for longs).

Cloud breakout. Price closing above the cloud after being below it signals a potential trend change.

Building Ichimoku in Setup.Cash

Add the Ichimoku indicator in the builder with its Tenkan/Kijun/Senkou settings, and create conditions on the cross or the price-vs-cloud position. Or describe it to text-to-strategy: "Long when price is above the Ichimoku cloud and Tenkan crosses above Kijun."

Strengths and Weaknesses

• Strength: a complete system — one indicator gives trend, momentum, and S/R, with the cloud as a high-quality filter.
• Weakness: lagging (built from longer averages) and ineffective in tight ranges where price sits inside the cloud.

Use the price-above/below-cloud rule as a powerful trend filter for other entries, even if you do not trade the crosses directly.

Tuning

The classic 9/26/52 settings are well-tested. Faster settings suit lower timeframes but add noise. Keep the displacement consistent and backtest any change.

Build a Custom Ichimoku Signal

In the Indicators Lab you can build a focused Ichimoku trigger — for example, a single "above cloud" boolean event — and wire it straight into entries. Generate it with AI or write it by hand.

Ichimoku rewards patience: its best use is as a trend and location filter, not a rapid-fire signal generator. Validate any Ichimoku strategy with backtesting and paper trading before risking capital.
