Spot gold

Spot gold (also called international spot gold and London gold) is a spot transaction, which means delivery after the transaction is completed or within a few days. Spot gold is an international investment product. Each gold company establishes a trading platform and conducts online trading transactions with market makers in the form of leverage ratios to form an investment and financial management project. Spot gold is also often called the world's largest stock. Because the daily trading volume of spot gold is huge, the daily trading volume is about 20 trillion US dollars. Therefore, no consortium or institution can artificially control such a huge market, and it depends entirely on the market's spontaneous regulation. There are no bookmakers in the spot gold market, the market is standardized, self-disciplined, and regulations are sound.

Spot silver

Spot silver, also known as international spot silver or London silver, is a contract-based transaction that uses the principle of financial leverage. It's not like the money we usually say, delivery once, but rather requires the delivery procedures to be completed within 1 to 2 working days after the transaction is completed. However, some investors do not actually deliver silver after the transaction, but only arrive at the scene of the transaction. Close the position in the future to earn profit from the price difference. Spot silver trading is based on U.S. dollars as the currency unit and ounces as the contract unit, and the price changes with market changes. The trading weight is based on 1 ounce, which is 1 lot. The trading unit is 100 ounces or its multiples. Investors can use the price of 1 ounce to purchase the trading rights of 100 ounces of silver and use the trading rights of these 100 ounces of silver. Buy up, sell down
