本程序基于C#控制台应用开发，二进制文件（文末附下载地址）需求支持库.NET Framework 4.6.1。主要实现了从HTTPS的JSON数据源获取结构化的股票数据，然后对数据进行分析处理，给出分析结论的功能。
先放上代码，后面再对代码进行解释。

Program.cs类是项目自动生成的类。作为程序的入口，并对程序的执行流程进行控制。流程控制主要分为几个部分：1.声明免责信息。2.构造Index类的对象集合，处理例子数据。3.通过无限循环读取用户输入的值构造Index对象，处理特定数据。
其中使用了Index类的两种构造方法。第一种只需输入股票符号，默认按从180个交易日前到今天进行数据获取。第二种需要输入股票符号、结束日期和交易日个数。
Rootobject.cs类由JSON字符串通过Visual Studio 2017的“将JSON粘贴为类”功能自动生成，作为反序列化后的模板和DataModel使用。需要注意的是，某些字段的基本变量类型要定义为长整形才由足够的空间存放数据。
Index.cs类为本程序的业务逻辑类。由构造函数负责获取拼接出股票数据源地址所需的所有参数。
FetchData方法中使用了HttpWebRequest去获取雪球数据源地址的JSON数据，并把JSON字符串反序列化为Rootobject对象，最后判断是否正确获得数据。这里两次进行GET Request是因为数据源需要先访问主页获取到Cookies权限才能正常访问到数据。
GetAntFortuneAlgrithmAdvice方法对指定交易日内的数据进行了遍历统计和分析。分析方法参照了蚂蚁财富的慧定投算法。
编写这个程序的目的是为了按照慧定投的模式对我购买5只互相关度最低指数型基金进行投资，关于股市指数的相关度自动计算程序可能以后会开发。
慧定投官方给出的跟踪标的并没有我需要的指数，而每个投资周期都去手动计算投资额又过于繁琐。所以本着“重复性的劳动交给程序处理，……”这一人生哲学信条，开发了本程序以解放劳动，同时得以回馈社区。
最后再次声明：本程序不代表任何投资建议，入市自负盈亏。
