老师你好，请问一下我这个编写的代码为什么会在图表上刚买就平仓，明明在平仓条件里加入了BarsSinceEntry > 0。

Params

Numeric Length1(5);

Numeric Length2(20);

Numeric ATRMA(20);

Vars

Series<Numeric> ma1;

Series<Numeric> ma2;

Global Numeric HHV;

Series<Numeric> ATR;

Global Bool ret1;

Global Bool ret2;

Global Numeric oParCl;

   Global Numeric oParOp;

   Global Numeric oPosition;

   Global Numeric oTransition;

Events

OnBar(ArrayRef<Integer> indexs)

{

ma1 = AverageFC(c[1],Length1);

ma2 = AverageFC(c[1],Length2);

PlotNumeric(MA1,ma1);

PlotNumeric(MA2,ma2);

ATR = AvgTrueRange(ATRMA);

ret1 = CrossOver(ma1,ma2);

ret2 = CrossUnder(ma1,ma2);

Commentary(ret1+IIFString(ret1, True, False));

Commentary(ret2+IIFString(ret2, True, False));

Bool ret = ParabolicSAR(0.02, 0.2, oParCl, oParOp, oPosition, oTransition);

If(oPosition == 1)

Commentary(多头);

If(oPosition == -1)

Commentary(空头);

If(ret1 And MarketPosition == 0 And Not ret2)

{buy(1,O);

HHV = o;}

If(MarketPosition == 1 And BarsSinceEntry > 0 And Not ret1 And ret2);

{Sell(1,O);

Commentary(平仓);}

If(MarketPosition == 1 And BarsSinceEntry > 0 And oPosition == -1)

{Sell(1,O);

Commentary(价格下降平仓);}

If(MarketPosition == 1 And BarsSinceEntry >0)

HHV = Max(HHV,O);

If(MarketPosition == 1 And BarsSinceEntry > 0 And Low < HHV - 4* ATR)

{Sell(1,HHV - 5* ATR);

Commentary(止损);}

}
