Data sources

Hi all,

Currently developing some systems and use data available on my broker account or through free sources (yahoo finance, barchart.com etc).

However, I find the detail lacking (i.e. only daily data) and would ideally like to breakdown to 4 hour at least. My broker only has data below daily timeframe for 12 months; which is not enough for robust backtesting.

I'm looking for some recommendations on data sources - ideally free ones, but happy to pay if necessary. Where are the best sources?

Many thanks in advance.

I am a big fan of Y Charts. Not free but not super expensive like Bloomberg

 

Don't know about any of these sites, I have always bought mine or accumulated from feeds.

Thanks both, will check out Y charts and the other link.

 

Many of the paid data providers could give you a month free for historical testing. You can try out Barcharts, DTN and if you d Futures, Rithmic.
