Precious metals are macro-priced products, and prices are driven by interest rates, inflation, the U.S. dollar, and geography. This article analyzes the core variables: the real interest rate determines the opportunity cost of gold holdings, the strength of the U.S. dollar is negatively correlated with the gold price in most stages, the central bank's gold purchase constitutes a long-term variable on the demand side, geopolitical uncertainty amplifies short-term fluctuations, and the industrial attributes of silver make the gold-silver ratio a relative strength indicator. Trading actions are extracted from the expected difference, and market charts and stop-profit and stop-loss tools are used to implement cognition into disciplined operations.
