Yahoo! Finance Historical Months

Usage

Excel formula:

=RTD("gartle.rtd",,"YahooFinanceHistoricalMonths","<Ticker>",[<date>],"<Data Field>")

where <date> is a Microsoft Excel date value or a string value as "yyyy-mm-dd".
If <date> is empty or equal to 0 then the last trade date is used by default. It is useful to monitor the last trade date data.

Example:

=RTD("gartle.rtd",,"YahooFinanceHistoricalMonths","YHOO","2014-12-31","Close")
=RTD("gartle.rtd",,"YahooFinanceHistoricalMonths","YHOO",,"Close")

Important Notes

Do not request the Yahoo! website frequently. Otherwise, your IP can be banned by the Yahoo! website.

Historical data for one ticker symbol are downloaded by one request to a web service. This feature significantly reduces the amount of requests to the Yahoo! website.

The amount of data depends on the entire data period that is calculated for all stocks in opened workbooks.
