策略：均线是中轨，均线+2个ATR是上轨，均线-2个ATR是下轨，收盘价突破上轨做多平空，收盘价突破下轨做空平多，这里面哪里有偷价或者信号闪烁问题，麻烦指导优化修改一下

代码：

Params

Numeric Length(30);

Numeric Length3(60);

Vars

Series<Numeric> atr;

Series<Numeric> upline;

Series<Numeric> downline;

Series<Numeric> myprice;

Series<Numeric> AvgValue3;

Events

 OnBar(ArrayRef<Integer> indexs)

 {

AvgValue3 = AverageFC(Close ,Length3);

atr = Average(TrueRange,30);

upline = AvgValue3 + 2 * atr;

downline = AvgValue3 -2 * atr;

PlotNumeric(\"k\",upline);

PlotNumeric(\"h\",downline);

PlotNumeric(\"AvgValue3\",AvgValue3);

If(MarketPosition<>1 && Close>upline)

{

Buy(0,Open);

}

If(MarketPosition<>-1&&close<downline )

{

SellShort(0,Open);

}

}
