Programm structure

This application is written in Java 8 and uses the ta4j-lib for indicator calculations, trading records and strategies. JFreeChart is the underlying charting application. For the GUI elements I have chosen JavaFX (earlier versions used swing).

There are four main classes:

• TaChart
  • This is the JavaFX node (StackPane) that holds the chart. It is the 'view' component of the application.
• ChartIndicatorBox
  • A ChartIndicatorBox is the 'model' component of the application. It stores the indicators, trading records and strategies that can/should be plotted. It also holds a reference to a PropertiesManager to establish a connection to a xml file that stores parameters of indicators.
• RootController.java
  • This is the 'controller' component of the application. It creates the TaChart node with help of a IndicatorBox. It also creates the menu entries and the toggle bar for active indicators inclusive logic.
• AbstractProgramm
  • This abstract class should make it easier for the user to start the application with customized indicators, strategies and trading records.
  • The user just has to override the abstract public ChartIndicatorBox createIndicatorBox(TimeSeries series) function to handle to the application the customized ChartIndicatorBox
