The Ichimoku Cloud, also known as the Ichimoku Kinko Hyo, is a Japanese charting technique that was developed by Goichi Hosoda in the 1930s. The name implies an ability to assess the balance of supply and demand in the market with just one glance. This technique consists of five lines and a shaded area, forming the cloud. The five lines are the conversion line (tenkan-sen), which averages the highest high and lowest low of the last nine periods; the base line (kijun-sen), which averages the highest high and lowest low of the last 26 periods; the leading span A (senkou span A), which is the average of the conversion line and base line, plotted 26 periods ahead; the leading span B (senkou span B), which averages the highest high and lowest low of the last 52 periods, plotted 26 periods ahead; and finally, the lagging span (chikou span), which is the current closing price, plotted 26 periods behind. The cloud between leading span A and B changes color depending on which line is above the other. It represents potential support and resistance levels, as well as momentum and volatility of the market.
