双均线跟踪止损50点代码怎么编程

Params Numeric FastLength(7);// 短期指数平均线参数 Numeric SlowLength(53);// 长期指数平均线参数Vars Series<Numeric> AvgValue1; Series<Numeric> AvgValue2;Events OnBar(ArrayRef<Integer> indexs) { AvgValue1 = AverageFC(Close,FastLength); AvgValue2 = AverageFC(Close,SlowLength); PlotNumeric(\"MA1\",AvgValue1); PlotNumeric(\"MA2\",AvgValue2); If(MarketPosition <>1 && AvgValue1[1] > AvgValue2[1]) { Buy(0,Open); } If(MarketPosition <>-1 && AvgValue1[1] < AvgValue2[1]) { SellShort(0,Open); } }//------------------------------------------------------------------------
