Order Book Rebates

Commission

Order book rebates represent a payment from an exchange to a liquidity provider for posting limit orders that rest on the order book, effectively narrowing the spread and increasing market depth. These incentives are particularly prevalent in high-frequency trading environments and cryptocurrency exchanges, where competitive order placement is crucial for capturing fleeting arbitrage opportunities. The economic rationale centers on internalizing order flow and reducing adverse selection costs for the exchange, while simultaneously encouraging market participants to contribute to a more efficient price discovery process. Rebate structures are often tiered, with larger rebates offered for providing liquidity in more actively traded instruments or at higher volumes, influencing trading strategies and overall market microstructure.
