London gold trading is not a kind of gold, but a way of precious metal margin trading. The narrow sense of London gold refers to 400 ounces of gold bars with a purity of 99.5% in the underground vault of London, while the broad sense of London gold refers to the spot gold traded.

In Asia, London gold is represented by Hong Kong gold market. In loco-London gold trading, investors don't need to extract physical gold, which saves the transportation, storage, inspection and identification of gold, and the difference between the buying price and the selling price is smaller than the difference between the buying and selling price of physical gold. In addition, some companies do not charge any commission or handling fee to customers, which further reduces the investment cost of investors.

In Hongkong, the authoritative representative of the gold market is the China Gold and Silver Exchange, which has been established for more than 100 years. It is the only gold and precious metal trading platform in Hong Kong, trading physical and spot gold. Any dealer who wants to become a member of the fair must first pass strict examination and approval. China Gold and Silver Exchange launched an electronic trading platform in 2008. Anyone who trades through an electronic dealer recognized by the gold and silver exchange can obtain the authentication transaction code issued by the exchange. Investors can check the trading data such as trading price, trading time and quantity on the website of the fair.

When investors choose dealers, they should take gold and silver dealers as the standard, then calculate the investment cost and income, and choose their own investment partners.
