1. External futures are usually called futures products in the international market, including gold futures, silver futures, crude oil futures, natural gas futures, foreign exchange futures and agricultural products futures of new york Stock Exchange. The basic metal futures of London Stock Exchange include copper futures, nickel futures, aluminum alloys, London zinc and new york copper. Financial index futures include Standard & Poor's 500 Index and Nasdaq 100 Index. Hong Kong's big Hang Seng Index futures and small Hang Seng Index futures, large and small H-share index futures, and Japanese rubber. (For more details, please see the following entries. The index futures of the above-mentioned outbound futures varieties are traded for 24 hours except Hong Kong trading hours.

2. External futures are traded 24 hours a day, with two-way operation without price limit, T+0 trading, trading on the global unified standardized contract exchange, leverage 14 to 28 times, global market, fairness, impartiality and openness, and continuous purchase price. The domestic futures market, trading at fixed trading hours every day, rises or falls by 4%-6%, and many institutional market makers with large funds are seriously manipulated and not fair and open enough. Shanghai T+D gold is traded at three fixed times in the morning, afternoon and evening, which is limited by price fluctuation. When the domestic market opens for trading, it happens to be the relatively off-season in the international market, while when the international market is active, it happens to be the domestic closed period. In this way, gold, copper, agricultural products and other products in the international market will fluctuate greatly, and the international market will fall or rise sharply. When the domestic market opens for trading the next day, it will be affected by the international market, which will lead to excessive losses for investors overnight. If you participate in foreign futures trading, you can close your position at any time, or you can set a stop loss to take profit, which can take effect on the same day or this week. When the market reaches your price, you can make a deal, control the loss and grasp the profit. If you pay attention to Shanghai T+D, you will know that the opening price is high or low almost every day, or there are many gaps.

3. Enterprises that make copper and metals basically use external futures for arbitrage and hedging.

4. Comparison between gold spot and futures: the leverage of gold spot ranges from 100 to 400 times, the spot has no delivery period, the futures has a delivery period, the spot is the current price, and the transaction needs to pay the price difference and transaction fee. Gold futures are future prices, there is no price difference between buying and selling, and the handling fee is low. Spot gold is two to three times the transaction cost of gold futures. Spot gold is dominated by the London market and has a market maker system. There is not much difference between gold spot and gold futures (at present, China is not allowed to engage in spot trading, so I won't elaborate. ), gold futures is an internal exchange transaction, which is a standardized contract and legalized in China.
