在ESPER中值增加超过100次时查找开始值和停止值

Question

我在ESPER遇到麻烦。

我有一个模拟库存文件，其中包含大量信息。

当BTC股票的加权价格增加超过100倍时，我想找出所有开始和结束日期。

这是文件的外观。这些是BTC股票：

2010-07-18,0.04951,0.08585,0.05941,0.08584,75.01,0.07 2010-07-19,0.08584,0.09307,0.07723,0.0808,574,0.09 2010-07-20,0.0808,0.08181,0.07426,0.07474,262,0.08

按顺序每个COMMA分离代表：时间戳，开放，高，低，收盘，交易量，平均值

所以基本上我应该做一个查询，做我上面说的^我似乎无法找出如何。我对CEP很新，所以我还在读它。

非常感谢任何帮助。

您可以使用＆＃34; prev＆＃34;增加命名窗口中的计数，或者针对聚合自定义趋势的API编写聚合函数。
