Ichimoku cloud is an overlay that provides all the information about the price trend at a glance, including its direction, momentum, dynamic support and resistance levels and even trade signals. It uses moving averages to show bullish and bearish crossover points.The ichimoku cloud consists of five plots.
- Conversion Line (9 period high+ 9 period low)/2))
- Base Line (26 period high + 26 period low)/2))
- Leading Span A (ConversionLine + Base Line)/2))
- Leading Span B (52 period high + 52 period low)/2))
- Lagging Span (Plotted 26 days in past)
Cloud, which is the most important feature of the overlay is formed between Leading Span A and the Leading span B plots and helps in identifying the trends. The trend is upwards when prices go above the cloud. However, it goes downwards when prices go below the cloud. When the Leading span A rises above the Leading Span B, it indicates strengthening of the upward trend. However, the downward trend strengthens when the Leading span B goes above the Leading Span A.
To use ichimoku cloud overlay in FinancialChart, add a FinancialChart control to your application and bind it to an appropriate data source using the DataSource property. The IchimokuCloud class allows you to modify the period values for each of the plotting lines, for example, conversion line has a default period of 9 days, however, you can modify the period value for conversion line using the ConversionPeriod property. Similarly, you can use BasePeriod, LeadingPeriod, and LaggingPeriod properties to modify the period values for base line, leading span, and lagging span respectively. Also, it provides styling properties for each of the five plots mentioned above, i.e. ConversionLineStyle, BaseLineStyle, LaggingLineStyle, LeadingSpanALineStyle, and LeadingSpanBLineStyle property. You can also set the color of bullish and bearish cloud using BullishCloudColor and BearishCloudColor properties respectively.
The following example considers stock data for a company Box Inc. over a period of time and plots ichimoku cloud on the same financial chart, as shown in the image above. The example uses data from a JSON file, and DataService.cs class is created to access the JSON file.
Make sure that Build Action property of the JSON file is set to Embedded Resource.
