Post-Only Orders: Spot & Futures Platform Implementations
Introduction
Welcome to the world of advanced order types! As you progress beyond simple market and limit orders on cryptocurrency exchanges, you'll encounter tools designed for more sophisticated trading strategies. One of these is the “post-only” order. This article will delve into post-only orders, explaining what they are, how they function on both spot and futures platforms, and how they are implemented on popular exchanges like Binance and Bybit. We'll focus on making this accessible for beginners, providing practical insights to help you leverage this powerful order type. Understanding post-only orders is crucial for traders aiming to minimize slippage, reduce fees, and potentially improve execution prices.
What is a Post-Only Order?
A post-only order is a type of limit order that *guarantees* it will be posted to the order book as a limit order, and *never* executed as a market order. This is different from a regular limit order which, if it can't be immediately filled at your limit price, might execute as a market order if you have 'Time in Force' settings allowing it. The primary purpose of a post-only order is to add liquidity to the order book, rather than taking it.
- Adding Liquidity: When you place a post-only order, you are essentially offering to buy or sell at a specific price, contributing to the depth of the order book.
- Avoiding 'Maker-Taker' Fees: Most exchanges use a "maker-taker" fee structure. "Makers" add liquidity (by posting limit orders), and "takers" remove liquidity (by filling existing limit orders with market or immediate limit orders). Makers typically pay lower fees than takers. Post-only orders guarantee you'll be a maker, thus benefiting from reduced fees.
- Controlling Execution: You have full control over the price at which your order is executed; it will only fill if the market reaches your specified limit price.
Spot vs. Futures: How Post-Only Orders Differ
While the core principle of a post-only order remains consistent, its application differs slightly between spot and futures trading.
- Spot Trading: In spot trading, you are buying or selling the underlying cryptocurrency directly. Post-only orders are particularly useful for long-term investors or traders looking to accumulate or distribute positions gradually while minimizing fees.
- Futures Trading: Futures contracts are agreements to buy or sell an asset at a predetermined price on a future date. Futures trading inherently involves leverage, which amplifies both potential profits and losses. Post-only orders in futures are crucial for managing risk and controlling entry/exit points, especially when dealing with leveraged positions.

Implementation Across Popular Platforms
Let's examine how post-only orders are implemented on Binance and Bybit, two leading cryptocurrency exchanges.
Binance
- Order Type: Binance offers a dedicated "Post Only" order type within its advanced order settings. This is found within the Limit order creation window.
- Setting the Order: When creating a limit order, you will find a checkbox labelled "Post Only". Checking this box ensures your order is always posted as a limit order and will not be executed as a market order.
- Fees: Binance's fee structure clearly outlines the maker-taker fees. Using post-only orders guarantees you receive the maker fee discount. The exact fee percentage depends on your 30-day trading volume.
- User Interface: Binance's interface is generally considered user-friendly, but can be overwhelming for beginners. The "Post Only" option is relatively easy to find once you navigate to the advanced order settings.
- Additional Notes: Binance allows you to set a 'Time in Force' for your post-only order (e.g., Good Till Cancelled - GTC, Immediate Or Cancel - IOC). GTC is the most common choice for post-only orders, allowing the order to remain active until filled or cancelled.
Bybit
- Order Type: Bybit also provides a "Post Only" order type. It's accessible within the Limit order creation panel.
- Setting the Order: Similar to Binance, Bybit has a checkbox labeled "Post Only" within the limit order settings. Selecting this option guarantees your order will be a limit order.
- Fees: Bybit also employs a maker-taker fee model. Post-only orders are essential for benefiting from lower maker fees, particularly for high-frequency traders.
- User Interface: Bybit's interface is often praised for its clarity and simplicity, making it potentially more accessible to beginners than Binance. The "Post Only" option is clearly visible and easy to activate.
- Additional Notes: Bybit offers advanced order types like "Reduce Only" which are distinct from "Post Only". "Reduce Only" is used specifically to reduce an existing position, while "Post Only" is for adding liquidity. It’s important not to confuse these two. Bybit also provides detailed documentation and tutorials on utilizing post-only orders.

Benefits of Using Post-Only Orders
- Reduced Fees: The most significant advantage is the reduction in trading fees by qualifying as a maker.
- Improved Execution: By avoiding market orders, you have more control over the price at which your order is filled, potentially leading to better execution prices.
- Liquidity Provision: You contribute to a healthier order book, benefiting all traders.
- Slippage Control: Post-only orders minimize slippage (the difference between the expected price and the actual execution price). This is especially important for large orders.
- Strategic Positioning: Allows for deliberate placement of orders in anticipation of market movements.
Risks and Considerations
- Order May Not Fill: Your order will only fill if the market reaches your specified limit price. If the price doesn't move in your favor, your order may remain unfilled for an extended period or be cancelled.
- Opportunity Cost: While your order is waiting to be filled, you might miss out on other trading opportunities.
- Requires Patience: Post-only orders are not suitable for traders who need immediate execution.
- Limited Flexibility: Unlike market orders, you cannot guarantee immediate execution.
Advanced Strategies with Post-Only Orders
- Layering Orders: Placing multiple post-only orders at different price levels to create a "ladder" of buy or sell orders.
- Dollar-Cost Averaging (DCA): Using post-only orders to buy a fixed amount of cryptocurrency at regular intervals, regardless of the price.
- Range Trading: Placing post-only buy orders at the support level and post-only sell orders at the resistance level of a trading range.
- Hedging: Utilizing post-only orders in futures markets to hedge against potential losses in your spot holdings. Effective risk management strategies, as discussed in [Mastering Risk Management in Bitcoin Futures: Essential Strategies for Hedging and Position Sizing], are crucial when employing hedging strategies.
Beginner’s Prioritization
For beginners, the following are essential when starting with post-only orders:
1. Understand Maker-Taker Fees: Thoroughly research the fee structure of your chosen exchange. 2. Start Small: Begin with small order sizes to get comfortable with the order type. 3. Use Limit Prices Wisely: Set realistic limit prices that are likely to be reached. 4. Utilize GTC (Good Till Cancelled): This ensures your order remains active until filled or cancelled. 5. Practice on Testnet: If the exchange offers a testnet (simulated trading environment), practice with post-only orders there before using real funds. 6. Monitor Your Orders: Regularly check the status of your post-only orders and adjust them as needed.
Conclusion
Post-only orders are a powerful tool for cryptocurrency traders of all levels. By understanding the underlying principles and how they are implemented on different platforms, you can significantly reduce your trading fees, improve execution prices, and contribute to a more liquid and efficient market. While they require patience and careful planning, the benefits can be substantial, especially for those aiming for a long-term, strategic approach to trading. Remember to thoroughly research and understand the risks involved before implementing post-only orders into your trading strategy.
