1. margin: in margin trading, buyers and sellers can make investment operations only by paying a small amount of margin to the broker. There are two purposes for paying the deposit:

(1) Protect the interests of the brokerage firm. When the customer fails to pay for some reason, the brokerage firm will compensate with the deposit.

(2) In order to control the speculative activities of the exchange. Margin is essentially a sum of money paid by a trader to a commodity clearing house through a broker, without calculating interest, to ensure that the trader has the ability to pay commissions and possible losses. But trading margin is by no means a margin for buying and selling futures.

Leverage: Leverage trading is also called virtual trading and deposit (margin) trading. That is, investors use their own funds as a guarantee to enlarge the financing provided by banks or brokers for spot trading, that is, to enlarge the trading funds of investors. The financing ratio is generally determined by banks or brokers. The greater the financing ratio, the less money customers need to pay.

Gambling involves black platforms, and formal platforms will not appear. I suggest you choose the national platform of Shanghai Gold Exchange, and you can find the Golden Point course for details.

For example, the market price of 1kg silver is 5,000 yuan, and you only need to pay 500 yuan to trade.
