请教大佬，我每次都必须在公式里修改交易手数，感觉很麻烦，怎么能在参数优化那里可以直接任意改手数呢？谢谢

Params

Numeric Ma_First_length(2);

Numeric Ma_Second_length(1);

Numeric Ma_Third_length(3);

Vars

Series<Numeric> Ma_First;

Series<Numeric> Ma_Second;

Series<Numeric> Ma_Third;

Bool dic_filter;

Series<Numeric> Vibration;

Series<Numeric> spread;Series<Bool> g;

Series<Bool> cro_over;

Series<Bool> cro_und;

Events

   OnInit()

   //=========除权换月相关设置==============

   AddDataFlag(Enum_Data_RolloverBackWard());    //设置后复权

   AddDataFlag(Enum_Data_RolloverRealPrice());    //设置映射真实价格
