目标¶

本示例旨在说明如何基于自定义的数据进行回测研究，例子以ETF回测为例，若是其他市场其他标的，同理即可。

策略逻辑¶

每日计算沪深300的5日均线和20日均线值

若5日均线大于20日均线，只持有a(注:a没有持仓就买入。b和c若有持仓就买出平仓)，建仓20%；

若5日均线小于20日均线，只持有b(注:b没有持仓就买入。a和c若有持仓就买出平仓)，建仓20%；

若5日均线小于20日均线，只持有c(注:c没有持仓就买入。a和b若有持仓就买出平仓)，建仓20%。

模块介绍¶

m2,数据源模块,读取基金日线行情数据

m1,自定义Python模块,过滤出三只ETF基金数据

m4,数据源模块,读取指数日线行情数据

m3,自定义Python模块,过滤出沪深300指数行情数据

m6,自定义Python模块,将沪深300指数数据和回测标的的历史行情数据整理到一起

m8,代码列表模块,指定回测标的、起始结束时间

m7,自定义Python模块,读取基准数据

m5,Trade(回测/模拟),回测执行模块
