老师：

  您好，我在OnBar运行两腿套利的程序发送信号到OnSignal,在OnSignal中用A函数发单开平仓，模拟交易已经有成交持仓了，但A_SendOrderEx()的返回值为False 。下面是OnSignal中的程序：

Onsignal(ArrayRef<Signal> sigs)

{

 signal mysig0;

 signal mysig1;

 SignalRef sig = sigs[i];

Integer i = 0;

  For i = 0 To GetArraySize(sigs) - 1

  {                                                                    

    If(sig.index==0)

     {

      mysig0=sig;

     If(!BitHas(sig.flag,Enum_Signal_NotSend)&&QuoteStatus==Enum_QuoteStatus_RealTime )

       {

        If(mysig0.side==1 and condition==0 )

         {

         Bool  ret0=data0.A_SendOrderEx(Enum_Buy,mysig0.combOffset,mysig0.volume, mytick.bidask1.bidP,myorderId);

          condition==1;      

          Print("data0.A_SendOrderEx:" + IIFString(ret0,"True","False");

          }

         If(mysig0.side==2 and condition==0)

          {

          Bool ret0=data0.A_SendOrderEx(Enum_Sell,mysig0.combOffset,mysig0.volume, mytick.bidask1.askP,myorderId);

             condition==1;

            Print("data0.A_SendOrderEx:" + IIFString(ret0,"True","False"));

           }

         }

        }

       If(sig.index==1)

       {

       mysig1=sig;

      If(!BitHas(sig.flag,Enum_Signal_NotSend)&&QuoteStatus==Enum_QuoteStatus_RealTime)

         {

           If(mysig1.side==1 and condition==0 )

           {

            Bool ret1=data1.A_SendOrderEx(Enum_Buy, mysig1.combOffset, mysig1.volume, mytick.bidask1.bidP,myorderId);

                condition==1;

              Print("data1.A_SendOrderEx:" + IIFString(ret1,"True","False"));

            }

            If(mysig1.side==2 and condition==0)

            {

            bool ret1=data1.A_SendOrderEx(Enum_Sell, mysig1.combOffset, mysig1.volume, mytick.bidask1.askP,myorderId);

               condition==1;

               Print("data1.A_SendOrderEx:" + IIFString(ret1,"True","False"))

              }

         }

       }

     }

   }
