标题：未成交单，隔几秒自动撤单的VBA代码

Sub OrderCheDan(iCheTime)  '获取未成交单，指定秒数后撤单
 dim Orderid   '订单ID
 dim Filled   '提交手数
 dim Remaining  '剩余手数
 dim Action   '买卖
 dim OrderType  '订单类型
 dim LmtPrice  '委托价
 dim Account   '账户
 dim Kaiping   '开平
 
 PendingCount=Order.OrderNum2
 For i=0 to PendingCount-1
  Call Order.OrderInfo2(i,OrderID,ConSign,Filled,Remaining,Action,OrderType,LmtPrice,Account,Kaiping,Code,Market)
  'application.MsgOut "PendingCount:" & PendingCount & ",OrderID:" & OrderID & ",Code:" & Code & ",lmtPrice:" & lmtPrice & ",Action:" & Action & ",Kaiping:" & Kaiping & ",Filled:" & Filled & ",Remaining:" & Remaining 
 'application.MsgOut Cdate(time) & ",sAction:" & sAction & ",sKaiping:" & sKaiping & ",LmtPrice:" & LmtPrice & ",OrderID:" & OrderID
   OrdTime=right(Order.OrderInfoTime2(i),8)    '订单的委托时间

   application.MsgOut "OrdTime:"&OrdTime
   if Datediff("s",OrdTime,Cdate(time))>iCheTime then    '超过间隔指定的秒数，就撤单
      Call Order.CancelOrder(OrderID)

   end if 
 Next
End Sub

调用以上代码的方式：OrderCheDan 5               '间隔5秒不成交就撤单

可以把这个过程放到计时器中，定时检测有没有未成交的单，有，而且超过时间就撤单。
