When the ratio is rising, it means gold is outperforming silver, and when the line is falling, the first term is doing worse, i.e., silver is doing better. In other words, when the ratio is high, the general consensus is that silver is favoured. Conversely, a low ratio tends to favour gold and may be a signal it’s a good time to buy the yellow metal. Despite the gold-to-silver ratio fluctuating so wildly, another way of using it is to switch holdings between silver and gold when the ratio swings to historically determined “extremes.”
In the Forex market, gold is a form of currency. The particularity of gold is that it can only be traded against United States dollars (USD). The internationally accepted code for gold is XAU. It is known to be a “safe-haven” asset, it is expected to increase its value in times of volatility and economic uncertainty.
The XAU/USD pair tells the trader how many US Dollar (the quote currency) are needed to purchase one Gold Ounce (the base currency). United States is the country that holds the biggest resources of gold in the world.
