外汇黄金投资需要使用货币对和黄金价格作为基准进行交易。

在外汇市场中，投资者可以通过借入另一种货币然后兑换成基础货币的方式，来增加他们的购买力。随后当汇率上升时，他们可以将其兑换回基础货币，从中获利。

黄金作为一种贵金属，通常被视为避险资产，在外汇市场不稳定时，投资者可以通过购买黄金来对冲风险。

In English:

Forex and gold investment require the use of currency pairs and gold prices as benchmarks for trading.

In the foreign exchange market, investors can increase their purchasing power by borrowing another currency and then converting it into the base currency. Subsequently, when the exchange rate rises, they can convert it back into the base currency to profit.

Gold, as a precious metal, is often considered a safe-haven asset. When the foreign exchange market is unstable, investors can hedge their risks by purchasing gold.
