交易,一根均线上多下空,能做到稳定盈利?是"大道至简",还是嘴盘忽悠?Python量化交易均线策略测试一中,我们用python程序量化测试了10日均线,50日均线作为单根均线策略,测试发现收益十分不理想。

今天我们继续对单根均线策略做量化测试,今天突然想起昨天的测试还有60日均线没有做量化测试,为什么要测试60日均线,因为60日均线太有名了,外号有牛熊分界线,万能均线,生命线等。

仅仅以股价大于60均线作为买入条件,最近三年收益如下:



60均线最近三年收益

我们再把昨天python量化交易测试的10日均线,50日均线收益图贴在下面,很明显60日均线收益确实整体要稍微好一些。



10日均线,最近三年收益



50日均线,最近三年收益

我们对60日均线策略买点做一些优化

1.股价大于60日均线,且均线趋势向上

2.股价大于30日均线,且均线趋势向上

3.股价大于10日均线,且均线趋势向上

回测最近三年收益如下:


擦,貌似越优化收益越差,这也是意料之外的事情,这个优化策略,是我在百度找的一篇洋洋洒洒写了1万多字,图文并茂,貌似,看起来大神给的策略,看起来大神给的策略,量化交易回测不行啊,未完待续。。。。。。

如果你有策略愿意让我量化测试一下,请加公众号:Python量化交易探索,留言告诉我。

60日均线策略,python量化交易代码如下:
