# Trading Costs and Secondary-Market Trading Revenue Market.Cards currently does not charge users a separate platform trading fee. Market.Cards generates secondary-market trading revenue through the bid-ask spread in trades. Put simply, there's usually a gap between what a buyer will pay and what a seller will accept. When orders are matched and executed, the platform or liquidity provider may receive a portion of that spread as secondary-market trading revenue. At the current stage, this secondary-market trading revenue is generally kept within **1%-3%** of the execution price. If the spread exceeds 3%, the platform returns the extra spread benefit to both the buyer and the seller. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
