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
