Experienced contract traders understand that, especially in high-leverage high-frequency trading, trading fees may seem insignificant, but in reality, they accumulate into a substantial expense. Don't underestimate the cost of each trade; over a week, the rebate mechanism can recover hundreds to thousands of U.S. dollars. Saving this money can significantly improve your quality of life. Upgraded smoking and drinking habits, better skincare products for your wife, affording tutoring classes for your children, and not having to skimp on health supplements for your parents—all these benefits are within reach. Many people fail to realize this and continue trading in environments with low rebates, wasting the profits they should have earned. Choosing the right exchange and optimizing rebate strategies can make these earnings essentially free.
