What are the maker taker fees for EXMO?

Excuse me, could you please clarify the maker-taker fee structure for trading on EXMO? I'm interested in understanding how much I would be charged for placing market orders as a taker and for adding liquidity to the market as a maker. Are these fees fixed or do they vary based on the trading pair or the volume of my trades? Additionally, are there any discounts or promotions available for high-volume traders or frequent users of the platform? Thank you for your time and assistance in clarifying this matter.
