IB Java API：为多个合同提取股票代码数据（实时条）

Question

我正在进行一些算法交易和IB API的自学和实验。 我决定使用Java，但我愿意切换到C ++。 我浏览了一个在线教程，它将引导您完成下面显示的代码，但是想知道是否仅将其扩展到一个库存。 我想查看所有SP500股票并查看股票代码数据，以便根据这些做出决策。

下面的代码将为Microsoft创建合同并获取数据，但我想获取所有500种股票的数据。 EWrapper界面中定义的所有其他方法都被排除在帖子之外，以便于阅读。

我想我需要将自动收报机符号存储在一个文件中，解析它，并将每个合约逐个添加到向量中。 但是，我不确定如何监控数据。 如果我可以按顺序循环遍历每个自动收报机并发出数据请求，那将是很好的但我相信流是在异步线程上处理的（如果错误则纠正我。）

那么如何查看所有500种股票并检查其股票数据呢？

代码片段和解释将不胜感激。 谢谢！
