leverage trading, also known as margin trading. As the name suggests, it is to use small amount of funds to invest several times the original amount in order to obtain multiple returns or losses relative to the fluctuation of the investment object. Different transaction leverage ratios are different. For example, futures generally have 10 times leverage, that is to say, if the market price changes in the opposite direction of your expectation, 10% of your investment (margin) will lose 100%, and if the market changes in the same direction as your expectation, the return will be 100%. If it is 100 times leverage trading, the market price changes by 10%, and the return or loss of investment will reach 1000%. As the increase or decrease of margin (the small amount of funds) does not move according to the fluctuation ratio of the underlying assets, the risk is very high
foreign exchange margin trading refers to signing a contract with (designated investment) bank, opening a trust investment account, depositing a sum of funds (margin) as guarantee, and setting a credit operation limit (i.e. 20-400 times leverage effect) by (investment) Bank (or brokerage bank). Investors can freely buy and sell spot foreign exchange of the same value within the limit, and the profits and losses caused by the operation will be automatically dected from or deposited in the above investment account. So that small investors can make use of smaller funds, get a larger amount of trading, and enjoy the use of foreign exchange transactions as global capital to avoid risks, and create profit opportunities in exchange rate changes
for foreign exchange leveraged transaction, the leverage ratio is between 20 times and 400 times, and the standard contract in the foreign exchange market is RMB 100000 per hand (which refers to the base currency, that is, the currency before the currency pair). If the leverage ratio provided by the broker is 20 times, the margin of RMB 5000 per hand (if the currency of the transaction is different from the gold coin of the account guarantee, it needs to be converted); If the leverage ratio is 100 times, a margin of 1000 yuan is required for the transaction.
