What is the fee structure of symbiosis?

Could you please elaborate on the fee structure of Symbiosis? I'm particularly interested in understanding how transaction fees are calculated and whether there are any additional costs associated with using the platform. Are there any incentives for high-volume traders or users who stake their tokens? Additionally, does Symbiosis offer tiered fee structures based on factors such as trading volume or account status? I'd appreciate any details you can provide to help me better understand the overall cost of utilizing Symbiosis for my financial needs.
