Vars
    Global Integer sendCount(0);
Events
    OnBar(ArrayRef<Integer> indexs)
    {
       if(sendCount == 0)  
       {//发开仓单      
       Array<Integer> orders;
            //指定账户指定合约开多头单
           Bool ret =  A_Sell(Symbol, A_BuyPosition(0), 0, orders, "", "") and A_BuyToCover(Symbol, A_SellPosition(0), Q_UpperLimit(), orders, "", "");
             
        if(ret)
            {
                sendCount = sendCount + 1;
            } 
        }    
    }
        

这段代码运行时怎么会产生2次开仓操作
