yahoo stock data url

Historical quotes can be requested for any period in the past. To request historical quote an URL in the following format is used:

http://ichart.finance.yahoo.com/table.csv?s=MSFT&a=02&b=13&c=2001&g=d&ignore=.csv

The following lists the parameters of this URL

Parameter	Description
s=MSFT	Symbol for quote requested
a=02	Start month of quote requested (Zero based). 00-January, 01-February, 02-March, etc
b=13	Start day of quote requested
c=2001	Start year of quote requested
g=d	Frequency of quote requested. Value d here stands for "Daily"

An example of the returned data is as follows:

Date,Open,High,Low,Close,Volume,Adj Close

Here's a neat way to download stock data from Yahoo, perhaps into a spreadsheet (so you can play with the data):

http://finance.yahoo.com/d/quotes.csv?s= a BUNCH of STOCK SYMBOLS separated by "+" &f=a bunch of special tags

for example: http://finance.yahoo.com/d/quotes.csv?s=XOM+BBDb.TO+JNJ+MSFT&f=snd1l1yr
