请教怎么在参数优化里显示交易手数修改

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 //=========交易相关设置============== } //Bar更新事件函数，参数indexs表示变化的数据源图层ID数组 OnBar(ArrayRef<Integer> indexs) { // IF(Date>=20240202)Return; Vibration = (Highest(High,Vibration_length)-Lowest(Low,Vibration_length))/Lowest(Low,Vibration_length); Commentary(\"Vibration\"+Text(Vibration)); Ma_First = AverageFC(Close,Ma_First_length); Ma_Second = AverageFC(Close,Ma_Second_length); //PlotNumeric(\"Ma_First\",Ma_First); //PlotNumeric(\"Ma_Second\",Ma_Second); //PlotNumeric(\"Ma_Third\",Ma_Third); If (Time >= 155500*0.000001 And Time <= 200500*0.000001 or Time >= 032500*0.000001 And Time <= 080500*0.000001) { Commentary(\"时间过滤\"); //PlotBool(\"aaa\",(Time >= 145500*0.000001 And Time <= 205500*0.000001)); if(MarketPosition ==1) { Sell(0,Open); } if(MarketPosition ==-1) { BuyToCover(0,Open); } Return; } If (Close[1] > Ma_First[1]) dic_filter = True; Else dic_filter = False; If(MarketPosition == 0 And Vibration>Vibration_val) { If(dic_filter And cro_over[1]) { Buy(1,Max(Open,Close[1])); buylasthigh=EntryPrice; } Else If(Not dic_filter And cro_und[1]) { SellShort(1,Min(Open,Close[1])); selllastlow=EntryPrice; }
