The spread is the difference between the buying price and the selling price. It is also the handling fee you pay to the platform. The trading software will display one buying price and one selling price. No matter what kind of investment it is, there are procedures. It's free, and the spread is actually a kind of handling fee. This is determined by the spot trading mechanism.

So why are there spreads?

Spot transactions have two prices, a buying price and a selling price. The spread refers to the fixed difference between the buying price and the selling price, that is, the buying price - the selling price = the spread. The spread is the transaction cost of the investor. The system charges a spread fee at the moment a position is opened. Spread fees are only charged in one direction when opening a position, and no spread fees are required when closing a position.

Spots have a short-selling mechanism, that is, you can make money by buying long, and you can make money by buying down. As for stocks, there is no short-selling, you can only buy up. If silver can only be bought up, then there is no spread. This is a saying, the exchange cannot give you a platform for you to make money for no reason. If there is no spread, the exchange will not lose money. If you buy it at the time, you can sell it immediately. The existence of the spread is for the masses to use this loophole to perform operations, and it is also a prevention and control measure for the exchange. Moreover, the spread accumulates over time, increasing like a snowball, so when there is a crisis in the market, its existence is also solved. In this crisis, there is a gap, that is, a price difference between buying and selling, which should exist as a matter of course.
