请教一下老师，用A_DeleteOrderEx用例代码测试，交易师手工下了几笔委托，撤单的时候，为什么手工单也全部撤掉了呢？

Vars
    Global Integer cancelId;
    Global Bool openOrder(False);
Events
    OnBar(ArrayRef<Integer> indexs)
    {
        if(BarStatus == 2 && !openOrder)
        {//发开仓单
            //针对当前策略应用的帐户、商品发送委托单
            Bool ret = A_SendOrder(Enum_Sell, Enum_Entry, 2, Q_UpperLimit, 0);
            Print(SellShort,A_SendOrder: + IIFString(ret, True, False));
            if(ret)
            {
                openOrder = True;
            }
            cancelId=createTimer(5000);
        }
    }
  
    OnTimer(Integer tid,Integer intervalMillsecs)
    {
        if(tid == cancelId)
        {//撤单
            Array<Integer> orderIds;
            //获取未完成的报单数组
            Bool ret = A_GetUnFillOrderIDs(orderIds, , 0);
            Integer i;
            For i = 0 To GetArraySize(orderIds) - 1
            {
                Print(accountIndex: + A_AccountID(0) + ,orderId: + Text(orderIds[i]));
                ret = A_DeleteOrderEx(orderIds[i]);//撤指定报单索引的委托单
                Print(A_DeleteOrderEx: + IIFString(ret, True, False));
            }
            StopTimer(cancelId);
        }
    }
