The calculation method for trading fees is actually not complicated. The basic platform fee is 0.05%, plus the fee from the liquidity aggregator, which together make up the total fee you need to pay. But the good news is that this rate is not fixed — exchanges offer a tiered system.

The fee tier mainly depends on your rolling trading volume over the past 14 days. At the end of each UTC day, the system will recalculate your fee rate, which means your tier may be adjusted at any time. The higher your trading volume, the more favorable your fee rate.

Particularly noteworthy is the order rebate mechanism. As a market maker, you can earn rebates when your orders are filled, which provides a significant cost hedge for frequent traders or users providing liquidity. For specific rebate ratios and threshold levels for each tier, it is recommended to check the platform documentation directly, as these parameters are updated periodically.
