double Lots=1.1;

bool bool1=true;

void OnStart()

  {

   int ticket;

   if(bool1){

     

      ticket=OrderSend(Symbol(),OP_BUY,Lots,Ask,3,0,0,"测试多",123,0,clrNONE);

      Print(rand(),"下多单",Ask,"订单号",ticket);

   }else if(!bool1){

      ticket=OrderSend(Symbol(),OP_SELL,Lots,Bid,3,0,0,"测试空",345,0,clrNONE);

      Print(rand(),"下空单",Bid,"订单号",ticket);

   };

  }

刚刚接触的新手，尝试写简单的脚本测试，然后发现无法成交， ticket输出为-1
