However, some investors don't actually deliver silver after trading, but just close their positions at maturity to earn the difference profit. Spot silver trading takes USD as the currency unit and ounces as the contract unit, and the price changes with the change of the market. The trading weight is 1 ounce, that is, 1 hand, and the trading unit is 100 ounce or its multiple. Investors can buy the trading right of 1 00 ounces of silver at the price of1ounce, and use the trading right of 100 ounces of silver to buy up and sell down, so as to earn the difference profit.
