How much is Phemex future fee?

Excuse me, could you please clarify the specific fee structure for Phemex futures trading? I'm particularly interested in understanding the magnitude of the fees associated with such transactions. Is there a standard rate for these futures fees, or does it vary based on factors such as trading volume or the type of contract being traded? Additionally, are there any potential discounts or incentives available for frequent traders or those meeting certain criteria? I would greatly appreciate any insights you can provide on this matter.
