OKX Introduces Enhanced Liquidity Program
OKX will introduce the Enhanced Liquidity Program (ELP) order type on December 3, 2025, a new order type designed to enhance liquidity and improve trade execution quality for non-API users of eligible OKX entities. ELP orders can be placed by all users and match only with taker orders that are not placed through OpenAPI.
By providing targeted liquidity, this program offers non-API users new economic incentives with price improvement and slippage reduction while maintaining transparency and market integrity across the platform.
Key features of ELP orders:
Order placement: All users can place ELP orders through OpenAPI.
Post-only mechanism: Always act as maker orders, which adds liquidity to the order book.
Exclusive matching: Match exclusively with taker orders that aren’t directly placed through OpenAPI.
Lower priority execution: Execute only after all non-ELP orders at the same price level are completed.
Order visibility: ELP orders will be displayed in the user interface without specific indications. There is a new data feed `
books-elp`in OpenAPI to return ELP orders.
ELP orders support all USDⓈ-margined perpetual futures symbols and USDⓈ-margined spot symbols during the initial release. For more details, refer to OKX Enhanced Liquidity Program.
