Dear HTX Users,
Starting on August 5, HTX will introduce the Retail Price Improvement (RPI) order type for spot and margin trading. This feature is designed to enhance market liquidity and provide retail users with an improved trading experience.
Initial Support Scope:
• The RPI order feature is supported only for spot and margin trading.
• RPI order placement is available only to approved, whitelisted market makers.
• RPI orders are supported only on designated whitelisted trading pairs.
Key Highlights:
• Exclusive Matching Mechanism: RPI orders match exclusively with non-algorithmic taker orders. These orders are completely invisible and inaccessible to API taker users, fostering a more balanced and equitable trading environment for retail traders.
• Maker-Only to Enhance Liquidity: RPI orders are strictly post-only (maker-only). This ensures they always act as liquidity providers in the order book and will never execute as a taker order, enhancing market depth and improving the overall retail trading experience.
• Open to Eligible Market Makers: During the initial phase, the RPI order feature is accessible to all eligible market makers to ensure high order quality and optimal market stability.
• Dedicated RPI Fee Structures for Selected Pairs: The RPI feature will first launch on designated whitelisted trading pairs, equipped with a dedicated RPI fee rate designed to incentivize market maker participation and enhance liquidity provision.
Important Notes:
• HTX will complete the launch of the RPI order feature for spot and margin trading by August 5.
• During the initial phase, this feature is supported only for spot and margin trading. Support for futures and other product lines will be announced separately in accordance with future plans.
• The products and services mentioned herein may not be available in your region.
