主题：怎么写VBA程序，实现数据接收模块里面的批量补数据功能，只要补充期货类数据就OK了

Sub SJBC()
if application.ReceiveDataStatus=0 then application.ReceiveData(1)
Application.PeekAndPump
application.SendMessage(33882)
call application.Settimer(1,600000)
call application.Settimer(2,9000000)
Set Wrap = CreateObject("DynamicWrapper")
Wrap.Register "user32.dll","FindWindowA","i=ss","f=s", "r=l"
Wrap.Register "user32.dll","FindWindowExA","i=llss","f=s", "r=l"
Wrap.Register "user32.dll","SendMessageA","i=lull","f=s", "r=l"
h = Wrap.FindWindowA("#32770","数据接收")
tab=Wrap.FindWindowExA(h,0,"SysTabControl32","")
TCM_SETCURFOCUS=4912
WM_SETFOCUS=7
WM_KEYDOWN=256
WM_KEYUP=257
BM_CLICK=245
Wrap.SendMessageA tab,TCM_SETCURFOCUS,2,0
h1=Wrap.FindWindowExA(h,0,"#32770","自定义补数据")
cb=Wrap.FindWindowExA(h1,0,"ComboBox","")
Wrap.SendMessageA cb,WM_SETFOCUS,0,0
Wrap.SendMessageA cb,WM_KEYDOWN,VK_DOWN,0
Wrap.SendMessageA cb,WM_KEYUP,VK_DOWN,0
bt=0
bt=Wrap.FindWindowExA(h1,0,"Button","开始补充")
Wrap.SendMessageA bt,BM_CLICK,0,0
if bt<>0 then todayhas=1
End Sub

这个代码好像是实现自定义的补数据功能，怎么实现批量补数据，只需要补充期货类数据就可以了

我在自定义补充数据时候，，添加品种时，我选择所有的期货合约，当出现移仓时出现新的合约时，请问是否还需要手动添加新的合约进去，他才回自动补充新的合约数据

当日收盘后，补充最近1天的数据是否是补充当天的数据

当日收盘后什么补充最近1天的数据是不是今天的数据还是昨天的数据，当日收盘后当日数据什么时候可以补充
