It is to avoid this risk that futures trading is needed. The original intention of establishing the futures market is to preserve the value, and the futures price is also expected, continuous and authoritative. There are four futures markets in China, Dalian Commodity Exchange, Shanghai Futures Exchange, Zhengzhou Futures Exchange and China Financial Futures Exchange. Compared with European and American futures exchanges, I personally think that domestic futures exchanges are not perfect enough. The international spot gold market is very mature, because the transaction volume is huge and there is no manipulation. You can find electronic traders in Europe, America and Hong Kong, download simulation trading software, and experience trading personally.
