# Introduction The Gamma Limit Order Hook system is a comprehensive limit order system for Uniswap V4 pools, enabling single-tick limit orders and scale orders that execute autonomously through swap hooks. ## Key Features ### Cost / Fee Distribution * FREE to create limit orders — No fees for order creation. Pay for only gas. * EARN swap fee revenues generated by single-tick liquidity positions * EQUITABLE fee revenue distribution among same-position limit orders based on order size and time in range ### Order Types * **Limit orders**: Single-tick limit orders that are automatically executed via swap hooks * **Scale orders**: Multiple single-tick limit orders that are placed across a price range. Up to 100 limit orders can be placed at one time at various price points ### Order Management * **Order execution**: Orders are automatically burned from the liquidity pool and held in Uniswap's PoolManager contract once executed * **Order claiming**: After orders are executed, users can claim their principal and fees earned from their single-tick positions * **Order cancellation**: Orders can be cancelled at any time. Any fees earned while position was active are claimed during cancellation * **Batch claiming/cancellation**: Claiming & cancelling multiple orders within a single transaction is available for gas efficiency ### --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
