Strategy Description

什么东西

FMZ本地存储调用简化工具 关于本地存储，请访问FMZ API文档

有什么用

简化了FMZ本地存储的调用方式，更加的优雅，不用再打_G()了

如何使用

导入模板

先复制这个模板到你的策略库，在你要使用这个工具的策略中勾选这个模板

在策略代码中

在策略开头用以下代码建立一个对象

PS = ext.PersistentStorage()

搞定 这个对象PS可以当作普通的Python字典来使用，但是只能存储可以JSON序列化的内容

关于此库

使用 WTFPL – Do What the Fuck You Want to Public License
