The price difference is the difference between the purchase price and the selling price, and it is also the handling fee you pay to the platform. The buying price and selling price will be displayed on the trading software.

So why is it a little bad?

Generally speaking, it is a fixed fee charged by others. Because the spot trading of crude oil follows the principle of market maker, the so-called market maker means that each investor's counterparty is an exchange. In this process, when the price of crude oil is 10. The price you sold to the exchange was 9.95, and the price when you bought it from the exchange was 10.05. Between buying and selling this, the exchange virtually earned your difference.

At the same time, because the counterparty is an exchange, in theory, the money you earn is earned from the exchange, and the loss is also lost to the exchange.
