背景

经过迭代 21 的修复之后，现在只剩下 8 个测试用例失败，这 8 个测试用例失败有一个共性问题，都是交易次数出现了问题，7 个交易次数是 0，一个交易次数非常夸张，都需要修复。

修复建议

  1. 现在这么多策略没有产生交易的原因，很可能是指标没有产生具体的值或者产生的值不对，修复建议是只修改相应的指标和 Indocator 类，而不是修改其他的部分。如果非必要，只去修改相应的指标即可。

限制

  1. 不允许修改测试用例

  2. 修改源代码之后，在开始测试的时候，需要 pip install -U . 安装新的代码

  3. 修复不能性能的大幅度下滑。

失败的测试用例：
