Limit post-only order

In the world of trading, understanding the various order types is crucial for optimizing your strategy and mitigating risk. One such order type is the limit post-only order. This article will delve into the intricacies of limit post-only orders, their benefits, and how they compare to other order types like market orders, stop limit orders, and iceberg orders. By the end of this guide, you'll have a thorough understanding of how to use limit post-only orders to your advantage.

What is a Limit Post-Only Order?

A limit post-only order is a type of limit order that ensures your order is added to the order book as a maker order, rather than being executed immediately as a taker order. This type of order is designed to add liquidity to the market, which can be beneficial for traders looking to avoid taker fees and potentially earn maker fees.

Key Characteristics of Limit Post-Only Orders

• Limit Price: The price at which you are willing to buy or sell an asset.
• Post Only: Ensures the order is added to the order book and not executed immediately.
• Maker Orders Add Liquidity: By adding your order to the order book, you contribute to market liquidity.

How Limit Post-Only Orders Work

When you place a limit post-only order, you specify a limit price at which you are willing to buy or sell an asset. If the order cannot be added to the order book without being executed immediately, it will be canceled immediately. This ensures that your order remains a maker order, adding liquidity to the market.

Example of a Limit Post-Only Order

Suppose the current market price of an asset is $100. You want to place a sell limit order at $105. By using a limit post-only order, your order will only be added to the order book if it does not match an existing order at the time of placement. If it does match, it will be canceled immediately, ensuring you avoid taker fees.

Comparing Limit Post-Only Orders to Other Order Types

Market Orders

Market orders are executed immediately at the best available price. While they guarantee execution, they do not guarantee the price, which can lead to slippage, especially in volatile markets.

Limit Orders

Limit orders allow you to specify the price at which you are willing to buy or sell an asset. Unlike market orders, they do not guarantee execution, but they do guarantee the price.

Stop Limit Orders

Stop limit orders combine the features of stop orders and limit orders. They become active only when the stop price is reached, and then they are executed as limit orders at the specified limit price.

Iceberg Orders

Iceberg orders consist of a large order split into smaller visible and hidden orders. This helps in executing large orders without disrupting the market.

Benefits of Using Limit Post-Only Orders

Avoid Taker Fees

By ensuring your order is added to the order book, you can avoid taker fees and potentially earn maker fees.

Add Liquidity

Maker orders add liquidity to the market, which can be beneficial for the overall market environment.

Mitigate Risk

By specifying a limit price, you can mitigate the risk of slippage and ensure your order is executed at your chosen price.

Time in Force Options for Limit Post-Only Orders

Good Till Cancel (GTC)

A GTC order remains active until it is either filled or canceled by the trader.

Immediate or Cancel (IOC)

An IOC order must be executed immediately. Any portion of the order that cannot be filled immediately is canceled.

Fill or Kill (FOK)

A FOK order must be executed in its entirety immediately, or it is canceled.
