Precious metals investment is divided into physical investment and leveraged electronic trading investment, as well as bank paper, gold, paper and silver. Among them, physical investment refers to the process that investors earn the difference by buying low and selling high when they are optimistic about the precious metal market. It can also be a means to avoid risks when the economic outlook is not optimistic, and realize the preservation and appreciation of assets. Electronic trading refers to the decision to buy or sell precious metals such as gold and silver according to market price fluctuations. This kind of transaction generally has leverage, which can make a big return at a small cost.

There are many kinds of precious metals that can be used for investment, all of which are financial derivatives of precious metals. Common precious metals investment varieties in the market are: gold spot, silver spot, London gold, Tiantongjin, AuT+D, AgT+D, futures gold, paper gold, paper silver, platinum and palladium. Due to different varieties, their trading methods are similar, but the margin ratio of margin trading (electronic trading) for such precious metals will be different. Considering the risk control and the lack of relevant professional knowledge of most investors, in order to protect the interests of individual investors, the margin ratio of all exchanges is in the range of 5%-20% so far.
