Maker-Taker Fee Models

The maker-taker fee model is a common pricing structure used by exchanges to incentivize liquidity. Under this model, traders who provide liquidity by placing limit orders (makers) are charged lower fees or even receive rebates, while traders who remove liquidity by placing market orders (takers) pay higher fees.

This structure is designed to encourage market makers to keep the order book deep and the spreads tight. The net effect is a more efficient market for all participants.

However, it can also lead to issues like "wash trading," where participants create fake volume to collect rebates. Exchanges must balance these incentives carefully to ensure they are promoting genuine liquidity provision rather than gaming the system.

This model is a foundational element of modern exchange economics and has a significant impact on trading strategy selection.
