Downloading weekly bar charts

Is it possibel for someone to download weekly barcharts into an excel spreadsheet (display 4 columns O/H/L/C) for free?

Once I get the data in a spreadsheet I can write my own program to do my own testing then.

Can i get this from yahoo or something?
Is it easy to do?

yes it is possible to do.

i use a program to do it for me called Databull DataBull : download stock quotes, historical quotes, futures and commodities
it outputs to many differnet formats including excel.

another site is eoddata FREE End of Day Stock Market Data and Historical Stock Prices
also just google "free stock market data" and you get a few other places that provide data.

good luck with your trading.
