Like gold, silver is an investment commodity that can be bought and sold 24 hours a day. The world's major markets include London, Zurich, new york, Chicago and Hongkong.

As early as the17th century, physical and futures silver were bought and sold in London. The London market set a fixed price every day, and buyers and sellers settled at a fixed price. Although London is still the most active physical market, most transactions are completed in the COMEX market in the United States in the form of contracts (paper and silver), and the spot price of silver is set by COMEX.

The price of silver is mainly affected by supply and demand. In recent years, the supply of silver is in short supply, which makes the fundamentals of silver strong. However, because silver is also a tangible asset and has the function of preserving value, it is also affected by inflation, fiscal deficit, global interest rate and other factors.
