Does anybody knows a website that provide free historical daily gold prices (London or NY), in format of Date, Open Price, High,Low,Close?
I checked Kitco but they don't publish that detailed data.

Answer
you could try http://www.netdania.com . it is a forex data feed but if im not mistaken, they also have Gold and Silver price. You must sign up (its totaly free) and install Java in your computer in order to use the chart. once youve singed up - Log in, click on "chart station" on the left menu and click "try demo".

You can also try http://www.barchart.com but this website is not interactive and the charts are only updated at the end of the day.
