Live online charts showing gold prices can be found at GoldPrice.org, GoldSeek.com and JM Bullion. All the sites update their data constantly, provide charts that show price trends and list gold prices per ounce, gram and kilo. Prices on all the websites are provided in a variety of currencies.
Online sites show the spot prices of gold. A spot price is what the worth of the gold is in that moment. Spot and future prices are determined by a variety of factors such as typical supply-and-demand economics. Prices are also affected by U.S. and global inflation, world events, the political climate and Federal reserve actions.
