Order Book
The Hyperliquid Order Book is the backbone of trading on the platform, designed to function similarly to centralized exchanges but with the advantage of being fully on-chain. This ensures transparency and fairness while maintaining high-speed matching and robust operations.
Overview of the Order Book 📘
Core Functionality: Each asset has its own order book, where orders are matched based on price-time priority.
Tick Size and Lot Size:
Prices are placed as integer multiples of the tick size.
Sizes are specified as integer multiples of the lot size.
On-Chain Matching: All operations occur directly on-chain, integrating seamlessly with the Clearinghouse to ensure margin and position checks are consistently enforced.
Key Features:
Fully On-Chain: Transparent and verifiable, with every operation recorded on the blockchain.
Margin-Integrated: Margin checks are conducted when orders are placed and again when they match, ensuring resilience against oracle price fluctuations.
Fair Matching: Orders follow a price-time priority, rewarding earlier placement at the same price level.
Order Types 🛒
Hyperliquid offers a wide range of order types, catering to diverse trading strategies:
Primary Order Types:
Market Order: Executes immediately at the current market price.
Limit Order: Executes at the specified limit price or better.
Stop Market Order: A market order activated when the price hits the stop price, used to limit losses or lock in profits.
Stop Limit Order: A limit order triggered at a selected stop price.
Advanced Order Types:
TWAP (Time-Weighted Average Price): Divides a large order into smaller sub-orders executed at intervals to minimize market impact.
Details: Sub-orders execute every 30 seconds, targeting the TWAP schedule while limiting slippage to 3%.
Scale Orders: Places multiple limit orders within a defined price range to capture volatility effectively.
Order Options ⚙️
Reduce Only: Ensures the order only reduces an existing position rather than opening a new one in the opposite direction.
Good Til Cancel (GTC): The order remains on the book until filled or canceled.
Post Only (ALO): Adds an order to the book without executing it immediately.
Immediate or Cancel (IOC): Cancels the order if it’s not immediately filled.
Take Profit (TP): Triggers a market or limit order to close a position at a specific profit level.
Stop Loss (SL): Triggers a market or limit order to close a position at a specified loss threshold.
TP/SL Orders:
Mark Price Triggered: TP/SL orders are activated using the mark price for accurate execution.
Drag-and-Drop Editing: Modify TP/SL directly on the TradingView chart.
Market vs. Limit TP/SL:
Market: Executes with a 10% slippage tolerance.
Limit: Allows traders to control slippage with aggressive or conservative limit prices.

Index Perpetuals 📊
In addition to spot-based perpetuals, Hyperliquid offers index perpetual contracts, which track formulas instead of spot prices.

Example Applications: Indices tracking market sentiment, weighted averages of token prices, etc.

Hyperps (Hyperliquid-Only Perps) 🚀
A unique offering by Hyperliquid, Hyperps are perpetual contracts that don’t require an external spot or index oracle price.
Funding Rates: Determined relative to an 8-hour exponential moving average of the mark price, reducing susceptibility to manipulation.
Conversion to Vanilla Perps: Once the underlying asset becomes widely traded on major platforms (e.g., Binance, Bybit), Hyperps transition to standard perpetual contracts.
Open Interest Caps: Initially limited to $1,000,000 for early market stability.
