Post-Only Orders: Spot & Futures Platform Availability & Benefits.
Post-Only Orders: A Beginner’s Guide to Spot & Futures Trading
Post-only orders are a powerful tool for traders looking to improve their execution and potentially reduce trading fees. However, they can seem complex for newcomers. This article will break down what post-only orders are, their benefits, how they work on popular platforms like Binance and Bybit, and what beginners should prioritize when using them. This guide will cover both spot trading and crypto futures markets. Understanding the nuances of these order types is crucial, particularly when navigating the potentially volatile futures market; remember to always have a solid risk management plan (How to Trade Crypto Futures with a Risk Management Plan).
What are Post-Only Orders?
Traditionally, when you place a limit order, the exchange will attempt to match it with existing orders in the order book. If there's a direct match, the order is filled immediately. However, if your limit order crosses the best bid or ask price (the current highest buy or lowest sell order), it can *take* liquidity from the market. Taking liquidity generally incurs a higher trading fee than *making* liquidity.
A post-only order instructs the exchange to *only* execute your order if it doesn’t immediately take liquidity. In other words, it must be placed as a limit order that sits on the order book, waiting for another trader to come to it. If your order would be filled immediately by hitting the existing best bid or ask, it will *not* be executed. It will remain a passive order, “posted” on the order book.
Benefits of Using Post-Only Orders
- Reduced Fees: This is the primary benefit. Most exchanges offer lower fees for makers (those who add liquidity) and higher fees for takers (those who remove liquidity). By using post-only orders, you ensure you’re always making liquidity, thus benefiting from the lower maker fees.
- Improved Execution (Potentially): While not guaranteed, post-only orders can lead to better execution prices, especially in volatile markets. By patiently waiting for a buyer or seller to come to your price, you avoid being ‘front-run’ or getting filled at a less favorable price due to rapid market movements.
- Discipline & Avoidance of Slippage: Post-only orders force you to be more disciplined, as they won’t fill if your price isn’t reached. This helps avoid impulsive trades and potential slippage (the difference between the expected price of a trade and the price at which the trade is executed).
- Strategic Order Placement: Allows for more strategic placement of orders based on support and resistance levels, rather than reacting to immediate price action.
Spot Trading vs. Futures Trading & Post-Only Orders
The applicability and benefits of post-only orders differ slightly between spot trading and crypto futures.
- Spot Trading: In spot trading, you're buying or selling the actual cryptocurrency. Post-only orders are useful here for reducing fees, especially for frequent traders. The impact on execution is less pronounced than in futures due to generally lower volatility.
- Futures Trading: Crypto futures involve contracts representing the future price of an asset. Here, post-only orders are *particularly* valuable. Futures markets are often more volatile, and the fee differences between making and taking liquidity can be significant. Using post-only orders becomes a key component of a robust trading strategy (Navigating the Futures Market: Beginner Strategies for Success). The potential for manipulation and slippage is higher in futures, making the disciplined approach enforced by post-only orders even more beneficial.

Post-Only Order Functionality on Popular Platforms
Let's examine how post-only orders are implemented on two leading exchanges: Binance and Bybit.
Binance
- Order Types: Binance offers a "Post Only" checkbox within the order placement window for both spot and futures trading. When checked, the exchange will only execute your limit order if it doesn’t take liquidity.
- Fees: Binance has a tiered fee structure. Maker fees are significantly lower than taker fees, especially for higher trading volume users. Using post-only orders ensures you consistently qualify for the lower maker fees. Binance's fee schedule is available on their website.
- User Interface: The Binance interface is relatively straightforward. The "Post Only" checkbox is prominently displayed during order creation. You can monitor your maker/taker fee ratios in your account overview.
- Considerations: Binance's order book is very liquid. This means your post-only orders are more likely to be filled quickly, but it also means there's a greater chance they might not be filled at all if the price moves away.
Bybit
- Order Types: Bybit offers a dedicated "Post Only" order type. Like Binance, it’s available for both spot and futures.
- Fees: Bybit also employs a maker-taker fee model, with substantial discounts for makers. Bybit frequently runs promotions that further reduce maker fees.
- User Interface: Bybit’s interface is generally considered cleaner and more focused on derivatives trading (futures, perpetual contracts). The "Post Only" option is clearly labeled in the order entry panel. Bybit provides detailed fee breakdowns and historical trading data.
- Considerations: Bybit’s liquidity, while growing, is generally lower than Binance’s, especially for less popular trading pairs. This could result in your post-only orders remaining unfilled for longer periods. However, Bybit offers advanced order types like "Reduce Only" which can be combined with post-only functionality for sophisticated risk management.

Beginner Prioritization: What to Focus On
For beginners, mastering post-only orders requires a gradual approach. Here's what to prioritize:
1. Understand Maker-Taker Fees: Before using post-only orders, thoroughly understand your exchange’s fee structure. Calculate how much you could save by consistently making liquidity. 2. Start Small: Begin with small order sizes to get comfortable with the process. Don’t risk significant capital until you’ve tested and understand how post-only orders work in live market conditions. 3. Use Limit Orders: Post-only orders *are* limit orders. Ensure you understand how limit orders function before adding the post-only constraint. 4. Patience is Key: Post-only orders require patience. Be prepared for your orders to remain unfilled for some time, especially in less liquid markets. Don't constantly adjust your limit price unless your trading strategy dictates otherwise. 5. Monitor Your Orders: Regularly check your open orders to ensure they haven’t been canceled or are still at a reasonable price. 6. Combine with Risk Management: Always use post-only orders in conjunction with a comprehensive risk management strategy (How to Trade Crypto Futures with a Risk Management Plan). Set stop-loss orders to protect your capital. 7. Practice on Testnet: If available, utilize the exchange’s testnet (simulated trading environment) to practice with post-only orders without risking real funds. 8. Avoid in Highly Volatile Situations (Initially): While post-only orders *can* be beneficial in volatile markets, beginners should avoid using them during periods of extreme volatility until they gain more experience. The risk of orders not being filled and missing out on opportunities is higher.
Advanced Considerations
- Iceberg Orders: Combine post-only orders with iceberg orders (which hide a portion of your order size from the public order book) to minimize market impact.
- Conditional Orders: Utilize conditional orders (e.g., "if-then" orders) to automate your trading strategy and react to specific market conditions.
- API Integration: For advanced traders, integrating post-only order functionality into automated trading bots via the exchange’s API can be highly efficient.
Conclusion
Post-only orders are a valuable tool for traders seeking to reduce fees, improve execution, and enhance their trading discipline. While they require a bit of understanding and patience, the benefits can be significant, particularly in the futures market. By starting small, understanding the fee structures of different platforms, and prioritizing risk management, beginners can effectively incorporate post-only orders into their trading strategies. Remember to continuously learn and adapt your approach as you gain experience in the dynamic world of cryptocurrency trading.
