Transaction fee rates are applied in two different ways as market maker and market taker. These;
Market Maker: It is the role taken when the entered order does not match a counter-order in terms of price. In other words, a buy order placed at a price lower than the lowest selling price or a sell order placed at a price higher than the highest bid price is recorded as a Primary Dealer. The market maker role is assumed in transactions that provide board depth, as they are not realized at the time the order is given.
Market Taker: It is the role taken when the entered order instantly matches with a counter-direction order at the current price. Orders placed in the Market Order type are instantly matched to the Market Buyer role. In this case, the user can instantly convert their assets by simply entering the amount.
In the market order, the system continues to automatically match, starting with the best orders, regardless of the price, until you complete the amount you set. For this reason, for the Market Order type, buying and selling may occur above or below the current price, and the amount you specify may not be bought or sold.
