Params

Numeric F1(10);// 短期指数平均线参数

Vars

Series<Numeric> AvgValue1;

Series<Numeric> AvgValue2;

Series<Numeric> AvgValue3;

Series<Numeric> AvgValue4;

Events

OnBar(ArrayRef<Integer> indexs)

{

AvgValue1 = AverageFC(Close,F1);

AvgValue2 = AverageFC(Close,F2);

AvgValue3 = AverageFC(Close,F3);

PlotNumeric(\"MA1\",AvgValue1);

PlotNumeric(\"MA2\",AvgValue2);

PlotNumeric(\"MA3\",AvgValue3);

If(MarketPosition ==0)

{

if(close[1] > AvgValue1[1]&&AvgValue1[1] > AvgValue2[1]&&AvgValue2[1] > AvgValue3[1]&&AvgValue1[1]>AvgValue1[2]&&

AvgValue2[1]>AvgValue2[2]&&AvgValue3[1]>AvgValue3[2])

Buy(1,Open);

if( close[1] <AvgValue1[1]&&AvgValue1[1] < AvgValue2[1]&&AvgValue2[1] < AvgValue3[1]
