TallyMoney uses the global gold market price for troy ounces, irrespective of the customer transaction amount. This can be independently verified by checking the live price at https://www.xe.com/currencyconverter/convert/?Amount=32.1507465686&From=XAU&To=GBP and converting troy ounces into milligrams. A simple and transparent flat fx rate of 0.99% and a 0.5% gold handling fee is charged, and then tally is held at the live market price, with no transaction fees or margins added when you send or spend your tally.
