想下载银行日股价数据，但是BANKFOCUS只能下载2年内的日股价数据，2年前的日股价数据好像需要怎么怎么转换计算什么的，找了好久找不到哇，向大神求教，跪谢！

下文是BANKFOCUS的提示信息，然而还是不会弄哇……

“The section ‘Daily pricing series’ presents the Daily Closing Prices and is updated on a daily basis. For the daily closing prices there can be a history of two years.
If interested in uploading the complete history (i.e. more than two years) of daily stock prices for a certain company this can be done via the Addin function. A new Addin template called "Daily stock prices.xlsm" has been created as an example which can be used. The history can go back to January 2002.”
