麻烦客服帮我把一个简单的均线模型改为金字塔的

//------------------------------------------------------------------------

Params
 Numeric FastLength(3);  //短周期
 Numeric SlowLength(10);  //长周期
  
 Numeric StopPoint(30);  //止损点
 Numeric WinPoint(100);   //止赢点
 
 Numeric FlostStopStartPoint(50);   //浮动止损启动条件
 Numeric FlostStopPoint(20);   //浮动止损点
 
 Numeric TradeUint(5); //每次交易手数
 
Vars
 NumericSeries AvgValue1;
 NumericSeries AvgValue2;
 BoolSeries bCrossOver(false);
 BoolSeries bCrossDn(False);
Begin
 AvgValue1 = AverageFC(CLOSE,FastLength);
 AvgValue2 = AverageFC(CLOSE,SlowLength);
 PlotNumeric("MA1",AvgValue1);
 PlotNumeric("MA2",AvgValue2);
 
 
  
 bCrossOver = CrossOver(AvgValue1,AvgValue2);
 bCrossDn   = CrossUnder(AvgValue1,AvgValue2);
 
 //均线交叉时开仓
 if(bCrossOver[1])
 {
  if(MarketPosition != 1)
   Buy(TradeUint,Open);
  
 }
 Else if(bCrossDn[1])
 {
  if(MarketPosition != -1)
   SellShort(TradeUint,Open);
 }
 
 //止盈止损
 SetWinPoint(WinPoint);
 //止损点
 SetStopPoint(StopPoint);
 //浮动止损
 SetFloatStopPoint(FlostStopStartPoint,FlostStopPoint);
 
 PlotNumeric("Assets",Available+PositionProfit+Margin);
 SetOwnAxis("Assets");
End

//PlotNumeric("MA2",AvgValue2);绘制均线

bCrossDn: = Cross(AvgValue2,AvgValue1);//判断是否下穿

//均线交叉时开仓
//if(bCrossOver[1])
{
if(MarketPosition != 1)
Buy(TradeUint,Open);上穿买入开仓

}
//Else if(bCrossDn[1])
{
if(MarketPosition != -1)
SellShort(TradeUint,Open);下穿卖出开仓
}
if bcrossover then buy(holding=0,5,marketr);
if bcrossdn then buyshort(holding=0,5,marketr);

if c-enterprice>100 then sell(1,0,marketr);
if enterprice-c>100 then sellshort(1,0,marketr);

if enterprice-c>30 then sell(1,0,marketr);
if c-enterprice>30 then sellshort(1,0,marketr);

if hhv(h,enterbars+1)>enterprice+50 and c<hhv(h,enterbars+1)-20 then sell(1,0,marketr);
if llv(l,enterbars+1)<enterprice-50 and c>llv(l,enterbars+1)+20 then sellshort(1,0,marketr);

均线交叉平仓同时反向开仓怎么写？

if bcrossover then buy(holding=0,5,marketr);
if bcrossdn then buyshort(holding=0,5,marketr);

改为：

if bcrossover then begin

   sellshort(1,0,marketr);

   buy(holding=0,5,marketr);

end
if bcrossdn then begin

   sell(1,0,marketr);

   buyshort(holding=0,5,marketr);

end
