Post-Only Orders: Spot & Futures Platform Availability & Benefits.
Post-Only Orders: Spot & Futures Platform Availability & Benefits
Post-only orders are a powerful tool for traders, particularly those focused on market making or minimizing slippage. While seemingly complex, understanding them can significantly improve your trading efficiency and potentially reduce costs. This article will break down post-only orders, their availability on popular crypto exchanges like Binance and Bybit, their benefits, and what beginners should prioritize when utilizing this order type.
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 a match is found, your order is *executed* immediately. However, sometimes your order might *take* liquidity – meaning it matches against an existing order, essentially filling someone else's order. This can incur higher fees on many exchanges.
A post-only order instructs the exchange to *only* add your order to the order book as a *maker* order. It will not execute against existing orders (taking liquidity). If your order isn’t immediately filled, it remains active in the order book, waiting for a *taker* to come along and fill it. If it never gets filled, it remains open until cancelled.
Essentially, you’re guaranteeing you’ll be providing liquidity to the market, and therefore, often benefiting from reduced maker fees.
Spot vs. Futures: Availability and Differences
Post-only orders are available on both spot and futures markets, however, their implementation and importance differ.
- Spot Markets: In spot trading, post-only orders are useful for traders who want to accumulate or distribute an asset slowly, without significantly impacting the price. They're also valuable for those seeking to benefit from maker fee rebates.
- Futures Markets: In futures trading, post-only orders are even more crucial. The funding rate mechanism in perpetual futures contracts can create opportunities for arbitrage. Post-only orders allow traders to establish positions strategically to capitalize on these funding rate differences, while minimizing taker fees that would eat into profits. Furthermore, managing risk in futures requires precision. As highlighted in [How to Use Stop-Loss Orders to Minimize Losses in Crypto Futures], proper risk management is paramount, and post-only orders can be combined with stop-loss orders to protect your capital.
Platform Comparison: Binance vs. Bybit
Let's examine how Binance and Bybit handle post-only orders:
Binance
- Order Type: Binance offers a “Post Only” order type within its limit order interface. When selected, the system will reject your order if it would immediately execute against an existing order in the order book.
- User Interface: The interface is relatively straightforward. When placing a limit order, a checkbox labeled “Post Only” is available.
- Fees: Binance has a tiered fee structure. Maker fees are generally lower than taker fees. Using post-only orders allows you to consistently benefit from these lower maker fees.
- Additional Features: Binance offers advanced order types like “Time in Force” (Good Till Cancelled, Immediate or Cancel, etc.) which can be combined with post-only orders for greater control.
- Futures Specifics: Binance Futures supports post-only orders, and they are commonly used by algorithmic traders and arbitrageurs. Understanding the nuances of futures trading, including technical analysis and risk management, is crucial for success.

Bybit
- Order Type: Bybit also provides a dedicated “Post Only” option when placing limit orders.
- User Interface: Bybit’s interface is generally considered clean and intuitive. The “Post Only” checkbox is clearly visible during order creation.
- Fees: Bybit’s fee structure is also tiered, with maker fees being lower than taker fees.
- Additional Features: Bybit offers features like conditional orders, which can be combined with post-only orders to automate trading strategies.
- Futures Specifics: Bybit is particularly popular for futures trading. The platform’s robust order book and low latency make it ideal for post-only order execution. However, beginners should be aware of common pitfalls. As detailed in [Common Mistakes to Avoid in Futures Trading], overleveraging and improper risk management are frequent mistakes.
| Feature | Binance | Bybit |
|---|---|---|
| Post-Only Order Availability | Yes | Yes |
| User Interface Clarity | Good | Excellent |

Benefits of Using Post-Only Orders
- Reduced Fees: The primary benefit is lower trading fees. By consistently acting as a maker, you avoid the higher taker fees. Over time, these savings can be substantial, especially for high-frequency traders.
- Minimized Slippage: Slippage occurs when the price at which your order is executed differs from the price you expected. Post-only orders, by adding liquidity to the order book, reduce the likelihood of significant slippage.
- Improved Order Fill Rates: While not guaranteed, post-only orders can sometimes result in better fill rates, particularly in less liquid markets.
- Strategic Position Building: For traders aiming to accumulate a position over time, post-only orders allow for a controlled and less disruptive approach.
- Arbitrage Opportunities: In futures markets, post-only orders are essential for exploiting arbitrage opportunities related to funding rates.
Beginner’s Guide to Utilizing Post-Only Orders
For beginners, here's a step-by-step guide:
1. Understand the Order Book: Before using post-only orders, familiarize yourself with the order book. Understand the difference between bids (buy orders) and asks (sell orders). 2. Start Small: Begin with small order sizes to get comfortable with the process. Don’t risk a significant portion of your capital until you fully understand how post-only orders work. 3. Choose Appropriate Price Levels: Set your limit price strategically. Consider support and resistance levels in technical analysis. Don't set your price too close to the current market price, as it might immediately execute as a taker order. 4. Utilize Time in Force Options: Select a suitable "Time in Force" option. "Good Till Cancelled" (GTC) allows your order to remain active until filled or cancelled. 5. Monitor Your Orders: Regularly check your open orders to ensure they are still active and at the desired price levels. 6. Combine with Stop-Loss Orders: Especially in futures trading, always pair post-only orders with stop-loss orders to limit potential losses. 7. Consider Liquidity: Post-only orders are most effective in markets with sufficient liquidity. In illiquid markets, your orders might remain unfilled for extended periods. 8. Understand the Implications of Funding Rates (Futures): If trading futures, carefully analyze funding rates before placing post-only orders. Be aware of the potential for positive or negative funding payments.
Common Mistakes to Avoid
- Setting Prices Too Close to the Market: This will likely result in your order being executed as a taker order, defeating the purpose of using a post-only order.
- Ignoring Order Book Depth: Insufficient order book depth at your chosen price level can lead to prolonged waiting times or unfilled orders.
- Overleveraging (Futures): Using excessive leverage can amplify both profits and losses. Always use appropriate risk management techniques.
- Not Using Stop-Loss Orders: Without a stop-loss order, you are exposed to unlimited potential losses.
- Trading in Illiquid Markets: Post-only orders are less effective in markets with low trading volume.
- Forgetting to Cancel Orders: Unfilled orders can tie up your capital. Regularly review and cancel any orders that are no longer relevant.
Conclusion
Post-only orders are a valuable tool for traders looking to reduce fees, minimize slippage, and strategically build positions. While they require a bit more understanding than simple market orders, the benefits can be significant, especially for active traders and those involved in futures trading. By carefully considering the platform features of exchanges like Binance and Bybit, and by adhering to the best practices outlined in this guide, beginners can effectively incorporate post-only orders into their trading strategies and improve their overall trading performance. Remember to always prioritize risk management and continuous learning to succeed in the dynamic world of cryptocurrency trading.
