I have just learned about futures contracts for gold and find this to be a quite interesting area in commodity trading. To participate in this type of contract, you need to open a futures account with a reputable futures company.

The advantage of gold futures contracts is that your profit or loss depends entirely on the price difference between the buying and selling points. If you hold the contract until it expires, a physical gold transaction will take place. These contracts usually have basic terms such as margin requirements, delivery months, minimum price fluctuations, and trading methods.

When it comes to the world's largest market for gold futures contracts, it must be the "New York Gold" on the New York Mercantile Exchange (COMEX). This is the most active trading venue with the highest liquidity. Currently, COMEX offers both standard gold contracts and mini gold contracts. The standard gold lot is 100 ounces with 99.5% purity, while the mini lot is only 50 ounces with a minimum price fluctuation of $0.25 per ounce.

The operation of gold futures contracts in New York is quite simple — it is a quoting mechanism similar to stock trading. The exchange does not directly participate in transactions but only provides the venue, tools, and regulations to ensure fairness for both parties. The trading hours for gold futures in New York last 23 hours each day, excluding weekends, with closing times from 5:15 to 6:00 a.m. local time for settlement.

In Asia, the Shanghai Futures Exchange also offers gold futures contracts but with some unique features. Each lot here is 1 kilogram of gold, traded with approximately 7x leverage and a minimum margin of 8% of the contract value. Interestingly, Shanghai supports T+0 trading and allows two-way trading, divided into morning and evening sessions. The minimum price fluctuation is 0.02 yuan per gram. However, when the market experiences significant volatility, temporary adjustments may be applied to better manage risks.
