COMEX Silver futures (SI) are the primary vehicle for trading silver. Silver is more volatile than gold, trading both as a precious metal safe haven and an industrial commodity (electronics, solar panels). Each cent move in silver equals $50 on the standard 5,000 oz contract — fast moves can generate (or cost) significant capital quickly.

COMEX Copper futures (HG) track the price of high-grade copper, often called 'Dr. Copper' for its ability to predict economic activity. Copper is essential in construction, electronics, and EV manufacturing. Rising copper prices often signal economic expansion; falling prices signal contraction.
Micro Silver futures offer reduced-size silver exposure at 1,000 ounces per contract. Given silver's volatility, the smaller contract size helps retail traders manage risk while maintaining real market exposure.
Platinum futures trade on NYMEX with a 50 oz contract size. Platinum has both precious metal and industrial applications (catalytic converters, hydrogen fuel cells). The platinum-gold spread is closely watched by precious metals traders.
COMEX Gold futures (GC) are the global benchmark for gold trading. With a 100 oz contract size, each $1 move in gold equals $100. Gold is traded as a safe-haven asset, inflation hedge, and macro trade against real interest rates. The gold futures market is deeply liquid, with daily volume regularly exceeding 200,000 contracts.
