## What is the Definition of Post-Only?

A post-only order is a type of limit order that ensures the order is only added to the order book and does not immediately execute against existing orders. If the order would result in an immediate match, it is either cancelled or adjusted to ensure it only acts as a maker, providing liquidity. This instruction is crucial for traders who wish to earn maker rebates or avoid taker fees. It prevents unintended immediate execution. The order is designed to contribute to market depth.

## What is the Function of Post-Only?

The primary function of a post-only order is to guarantee that the trader acts as a liquidity provider, thereby potentially earning maker fees or avoiding taker fees, which can significantly impact profitability for high-frequency strategies. It ensures the order rests on the book, contributing to market depth rather than consuming it. This mechanism is particularly valuable in markets with differential fee structures. It supports passive trading strategies. The function helps manage trading costs effectively.

## What is the Application of Post-Only?

In cryptocurrency and derivatives trading, post-only orders are widely applied by market makers and algorithmic traders seeking to profit from bid-ask spreads while minimizing transaction costs. These orders are essential for strategies that rely on providing liquidity and collecting rebates. They are also used to manage market impact for large positions, slowly accumulating or distributing assets without aggressively moving prices. This application enhances capital efficiency. It is a fundamental tool for sophisticated market participants.
