Maker/Taker Fees

Most exchanges charge different fees depending on whether your order adds liquidity to the order book or removes it. A maker order (e.g. a limit order that doesn't execute immediately) sits on the book waiting to be filled, adding liquidity — and is usually charged a lower fee, since it helps other traders find a counterparty. A taker order (e.g. a market order) executes immediately against existing orders, removing liquidity, and typically pays a higher fee. Trading volume over time often unlocks lower fee tiers on both sides, which is worth checking before choosing where to trade actively.
