With the Ichimoku Cloud, all you need to keep track of are the cloud and the momentum indicator, aka the lagging span (usually colored in green). To enter a short position (to sell a certain currency pair), make sure that the momentum indicator and the price are below the cloud. To enter a long position (to buy), make sure that the momentum indicator and the price are above the cloud.
The Ichimoku cloud is quite a powerful tool to help you catch trends. This indicator was invented by a Japanese journalist named Goichi Hosoda. It is great in trending markets but can be misleading is sideways markets.
Before entering a position based on the above setups, it is critical to ensure that you are in a trending market. To do so, drawing trendlines and trading the breakout will help you avoid some costly mistakes. Combining Ichimoku cloud analysis with other technical or fundamental indicators usually gives you the best results.
