--  写一个次主力合约
最近在研究跨期套利，想写一个次主力合约的数据输出，或者直接在指定板块新建一个“次主力”合约，写了好久还是没有搞定。高手们能指教一下吗？

Sub getcizhuli()

pz = "cu "\'定义品种
pzzms = 2
sc = "sq" \'定义市场
maxOpenint = 0
midOpenint = 0
minOpenint = 0


lxhy = pz&"00"
Set History = marketdata.GetHistoryData(lxhy,sc,5)
    Count = History.Count-1
    for i=0 to Count
    mxdate = History.Date(i)
    Openint = History.Openint(i)
   
    n = marketdata.GetReportCount(sc)
    For j = 0 To n - 1
        Set report1 = marketdata.GetReportDataByIndex(sc, j)
            If left(report1.Label,2) = pz  Then
               Set History1 = marketdata.GetHistoryData(report1.Label,sc,5)
                    Count1 = History1.Count-1         
                    for m=0 to Count1
                    date1 = History1.Date(m)
                        if date1=mxdate then
                           Openint1 = History1.Openint(m)
                          
                              if Openint1 > maxOpenint then
                              maxOpenint = Openint1
                              elseif  Openint1 > midOpenint then
                              midOpenint = Openint1
                              else
                              minOpenint = Openint1
                              end if
                          
                
                        end if
                    next
              \'application.MsgOut mxdate&" "&report1.Label
            End If
          
    Next
   
    application.MsgOut mxdate&" "&midOpenint
    next


End Sub

 

以上红色部分数据输出有问题，请指教
