Refers to gold derivatives traded in the form of contracts for differences, and their prices are based on COMEX's gold futures contracts. Cfd transaction is a financial transaction based on leverage. Traders can gamble on the price of gold by paying a small margin (the margin required by the exchange), and can buy more or sell short. Different from the actual purchase of gold, cfd trading allows traders to enter and leave the market quickly, with higher flexibility and lower cost. However, due to the nature of leveraged trading, cfd trading also has high risks, so investors should be cautious in trading and strictly control risks.
