Foreign exchange margin trading (also called foreign exchange speculation) refers to signing a contract with a (designated investment) bank, opening a trust investment account, and depositing a sum of funds (margin) as a guarantee. The bank (or brokerage house) sets the credit operation limit (that is, a leverage effect of 20-400 times, and it is illegal if it exceeds 400 times). Investors can freely buy and sell spot foreign exchange of the same value within the quota, and the profits and losses caused by the operation will be automatically deducted or deposited from the above-mentioned investment account. Allow small investors to use smaller funds to obtain larger transaction limits, enjoy the same use of foreign exchange transactions as global capital to avoid risks, and create profit opportunities in exchange rate changes. Generally speaking, foreign exchange speculation is an investment behavior.
