Money market funds refer to funds that invest in short-term securities in the money market. Money fund is a collection of social idle funds, operated by fund managers, with high security, high liquidity and stable income. The assets of the Fund are mainly invested in short-term monetary instruments, such as treasury bills, commercial paper, bank time deposit certificates, government short-term bonds, corporate bonds, interbank deposits and other short-term securities. However, there are many similarities between foreign exchange margin trading and gold margin trading. The trading methods of the two products are almost the same, such as two-way trading, 24-hour trading and leveraged trading.
