Gold is traded virtually 24 hours a day, being a universal commodity, and the prices are constantly moving. You can track spot prices online or via trusted apps such as Moneycontrol Market, iBullion (Android), Gold Tracker (iOS), etc. \r\rPrices of Gold ETFs are also listed on the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE), where they are traded. Even though they mirror gold spot prices, your actual cost of buying/selling will differ on account of expense charges and brokerage.\r\r\rAlternatively, as an offline source, you can walk into any bank branch, which will have the gold price listed for the business day. However, retail rates have a higher markup compared to ETFs.
