有同学留言问，有用过20日线做量化分析吗？牛股一般是20日线做为生命线，20日也是一个月的交易时间。
其实在哈尔兹法则策略量化三（继续优化买点，加入均线系统）中我们有加入20日线的，即在哈尔兹法则的买入条件，股从低价上涨10%的基础上加入5日均线>10均线>20日均线，当时最近三年的收益如下图：
考虑到当时是对哈尔兹策略的优化，所以我们今天以20日单均线作为买卖点，即：
买点，股价大于20均线,买入
卖点，1.股价小于20日均线卖出
2.买入之后，亏损达到0.05%，止损
3.买入之后，超过10天，卖出，这条是为了方便短线分析加的
最近三年收益如下图：
如果你有策略，想法愿意让我量化测试一下，请加公众号：Python量化交易探索，请留言告诉我，感谢。
有同学留言，把牛股启动时的量，价，换手率，这些指标量化，找到刚启动的股票，后续我会尝试做一些妖股启动前，启动时的量，价，换手率，看看是否有相同点，请听后续分解。
20日单均线，python量化交易代码如下：
