主题：我这样的代码获取MACD的数据对吗？

Set ReportData = Grid.GetReportData() 

Application.MsgOut ReportData.Label
Application.MsgOut ReportData.MarketName
sPolicyName="MACD"
iPeriod=6
Set Formula = marketdata.STKINDI(ReportData.Label,ReportData.MarketName,sPolicyName,0,iPeriod)  
iDIFFs=Formula.GetBufData("DIFF",Formula.DataSize-1)
Application.MsgOut iDIFFs
iDEAs=Formula.GetBufData("DEA",Formula.DataSize-1)
Application.MsgOut iDEAs
iMACDs=Formula.GetBufData("MACD",Formula.DataSize-1)
Application.MsgOut iMACDs
为什么我输出的值貌似不对，我是获取日线的数据？
