这是在tb公式指南中，A函数与全局变量匹配使用小节中的一条语句：DeleteOrderTickCounter = DeleteOrderTickCounter + 1;不明白的是，为什么要在这里将该变量+1处理呢？？？

这是整段代码：

Params
Numeric offSet(1); // 委托价格偏移，为了保证成交
Numeric BeforeMins(5); // 收盘前几分钟开始操作
Vars
Numeric tempPos; // 仓位
Numeric DeleteOrderTickCounter;
Numeric HasSendOrder(0);

Begin
If(BarStatus == 0)
  {
DeleteOrderTickCounter = 9999;
HasSendOrder = 0;
SetGlobalVar(0,DeleteOrderTickCounter);
SetGlobalVar(1,HasSendOrder);
  }Else
  {
DeleteOrderTickCounter = GetGlobalVar(0);
HasSendOrder = GetGlobalVar(1);
}
If(CurrentTime > (0.1459 - 0.0001*(BeforeMins-1)) && BarStatus == 2 && HasSendOrder == 0)
{
   If(Data0.Close != InvalidNumeric && Data0.A_GetOpenOrderCount()>0) //商品0全部撤单
      {
         Data0.A_DeleteOrder();
         DeleteOrderTickCounter = 1;
      }
   If(Data1.Close != InvalidNumeric && Data1.A_GetOpenOrderCount()>0)//商品1全部撤单
      {
         Data1.A_DeleteOrder();
         DeleteOrderTickCounter = 1;
      }
   If(Data2.Close != InvalidNumeric && Data2.A_GetOpenOrderCount()>0) //商品2全部撤单
      {
         Data2.A_DeleteOrder();
         DeleteOrderTickCounter = 1;
         }
   DeleteOrderTickCounter = DeleteOrderTickCounter + 1; //就是这里看不明白？？？
   SetGlobalVar(0,DeleteOrderTickCounter);
   If(DeleteOrderTickCounter < 5) Return; // 撤单后需要延迟几个Tick才平仓
   tempPos = Data0.A_BuyPosition();
   If(tempPos > 0) // 平多单
         {
         Data0.A_SendOrder(Enum_Sell,Enum_Exit,tempPos,Data0.Q_BidPrice - offSet* Data0.MinMove*Data0.PriceScale);
         }
   tempPos = Data0.A_SellPosition();
   If(tempPos > 0) //平空单
      {
         Data0.A_SendOrder(Enum_Buy,Enum_Exit,tempPos,Data0.Q_AskPrice +offSet*Data0.MinMove*Data0.PriceScale);
      }
   tempPos = Data1.A_BuyPosition;
   If(tempPos > 0) // 平多单
      {
         Data1.A_SendOrder(Enum_Sell,Enum_Exit,tempPos,Data1.Q_BidPrice -offSet*Data1.MinMove*Data1.PriceScale);
      }
   tempPos = Data1.A_SellPosition;
   If(tempPos > 0) //平空单
      {
      Data1.A_SendOrder(Enum_Buy,Enum_Exit,tempPos,Data1.Q_AskPrice +offSet*Data1.MinMove*Data1.PriceScale);
      }
   tempPos = Data2.A_BuyPosition;
   If(tempPos > 0) // 平多单
      {
      Data2.A_SendOrder(Enum_Sell,Enum_Exit,tempPos,Data2.Q_BidPrice -offSet*Data2.MinMove*Data2.PriceScale);
      }
   tempPos = Data2.A_SellPosition;
   If(tempPos > 0) //平空单
      {
      Data2.A_SendOrder(Enum_Buy,Enum_Exit,tempPos,Data2.Q_AskPrice +offSet*Data2.MinMove*Data2.PriceScale);
      }
   HasSendOrder = 1;
   SetGlobalVar(1,HasSendOrder);
}
End
