Margin trading means that investors can conduct large transactions beyond their own financial strength by providing only a part of the funds as a deposit, which improves the utilization rate of funds. For example, in the international spot gold margin trading, investors use $65,438+00,000 as the margin and control the financial strength of $654,380+000 to complete the gold trading. Under normal circumstances, the deposit can be regarded as a deposit, and they can only have the right to trade goods if they pay a certain deposit first. The ratio of deposits is the leverage ratio.
