Post-Only Orders: Platforms Supporting Spot & Futures Efficiency.
Post-Only Orders: Platforms Supporting Spot & Futures Efficiency
Post-Only orders are a powerful tool for traders seeking to improve execution prices and minimize slippage, particularly in active markets. This article will delve into the mechanics of post-only orders, explore which platforms support them for both spot and futures trading, and provide a beginner-friendly guide to leveraging this feature. We’ll focus on popular exchanges like Binance and Bybit, outlining their specific implementations and what new traders should prioritize. Understanding post-only orders can significantly enhance your trading efficiency, especially when combined with an understanding of liquidity in futures markets (as discussed here).
What are Post-Only Orders?
Traditionally, when you place a limit order, the exchange attempts to *fill* it immediately at the best available price. However, this can sometimes result in your order "making" the market – meaning it’s the first order at that price, and other traders are filling *your* order. While making the market isn't inherently bad, it can be less desirable if you're prioritizing price improvement.
A post-only order instructs the exchange to *only* post your order as a limit order and *not* to fill it immediately by taking liquidity from the order book. In other words, it guarantees your order will always be a “maker” order, earning you maker fees (which are typically lower than taker fees). If your order isn't filled because no one is willing to trade at your price, it remains open in the order book until it’s either filled, cancelled, or expires.
Key Benefits of Post-Only Orders:
- Lower Fees: Maker fees are generally lower than taker fees, leading to cost savings, especially for high-frequency traders.
- Price Improvement: By avoiding immediate execution, you have a higher chance of getting a more favorable price if the market moves in your direction.
- Reduced Slippage: Slippage occurs when the price at which your order is filled differs from the price you intended. Post-only orders help minimize this by ensuring your order is only filled at your specified price or better.
- Strategic Order Placement: Allows for strategic placement of orders to influence market direction or capitalize on anticipated movements.
Platforms Supporting Post-Only Orders
Not all exchanges offer post-only functionality. Below is an analysis of some popular platforms, detailing their support for post-only orders in both spot and futures trading:
Binance
Binance is one of the largest cryptocurrency exchanges globally, and it offers robust post-only order functionality.
- Spot Trading: Binance allows users to select "Post Only" as an order type when placing limit orders. This ensures the order is always a maker order. The user interface is relatively straightforward, with a clearly marked checkbox or option to enable post-only mode.
- Futures Trading: Binance Futures also supports post-only orders. Within the order entry panel, there's a dedicated "Post Only" option. This is beneficial for traders employing strategies like order layering or attempting to capture the spread.
- Fees: Binance's fee structure is tiered based on trading volume and VIP level. Maker fees are consistently lower than taker fees. Using post-only orders allows you to consistently benefit from the lower maker fee tier.
- User Interface: Binance’s UI can be overwhelming for beginners. However, the post-only option is usually clearly labeled within the advanced order settings. New users might need to explore the different order types to locate it.
Bybit
Bybit is a popular exchange known for its derivatives trading, particularly perpetual contracts.
- Spot Trading: Bybit's spot trading platform supports post-only orders. The feature is integrated into the limit order placement process, allowing traders to specify "Post Only" when setting their price.
- Futures Trading: Bybit is particularly strong in its support for post-only orders within its futures trading environment. It offers a dedicated "Post Only" order type, enabling traders to strategically place limit orders without taking liquidity.
- Fees: Bybit offers competitive fees, with maker fees significantly lower than taker fees. The consistent use of post-only orders can result in substantial savings, particularly for active futures traders.
- User Interface: Bybit generally has a cleaner and more intuitive user interface compared to Binance, making it easier for beginners to navigate and locate the post-only order option. The order entry panel is well-organized and clearly displays the available order types.
Other Platforms
Many other exchanges are beginning to incorporate post-only order functionality, driven by demand from sophisticated traders. Some notable examples include:
- OKX: Supports post-only orders for both spot and futures trading.
- Bitget: Offers post-only functionality primarily within its futures platform.
- Kraken: Supports post-only orders on its spot market.

Understanding Order Types & Post-Only Interaction
To effectively use post-only orders, it's crucial to understand the different order types available on these platforms:
- Limit Order: An order to buy or sell an asset at a specific price or better. Post-only orders are a type of limit order.
- Market Order: An order to buy or sell an asset immediately at the best available price. Market orders *always* take liquidity.
- Stop-Limit Order: An order to trigger a limit order when the price reaches a specified level.
- Stop-Market Order: An order to trigger a market order when the price reaches a specified level.
When using a post-only order, you are essentially placing a limit order that will *not* be filled unless someone else is willing to trade at your price. This means your order will remain in the order book as a "maker" order until it's either filled, cancelled, or expires. Combining post-only orders with stop-limit orders can create powerful trading strategies.
Fees and Cost Savings
The primary benefit of post-only orders is the reduction in trading fees. Exchanges typically employ a “maker-taker” fee model:
- Maker Fees: Fees paid when you add liquidity to the order book (i.e., place a limit order that isn't immediately filled).
- Taker Fees: Fees paid when you remove liquidity from the order book (i.e., place a market order or a limit order that is immediately filled).
Maker fees are generally lower than taker fees, incentivizing traders to provide liquidity. By consistently using post-only orders, you ensure you're always paying the lower maker fees. The exact fee structure varies between exchanges and depends on your trading volume and VIP level. Always review the exchange's fee schedule before trading.
| Exchange | Spot Maker Fee (Example) | Spot Taker Fee (Example) | Futures Maker Fee (Example) | Futures Taker Fee (Example) | |||||
|---|---|---|---|---|---|---|---|---|---|
| Binance | 0.10% | 0.10% | -0.025% | 0.075% | Bybit | 0.05% | 0.10% | -0.025% | 0.075% |
- Note: Fees are subject to change and depend on trading volume and VIP level. These are examples only.*
Beginner's Guide to Using Post-Only Orders
Here's a step-by-step guide for beginners on using post-only orders:
1. Choose a Platform: Select an exchange that supports post-only orders, such as Binance or Bybit. Bybit is often recommended for beginners due to its more intuitive interface. 2. Navigate to the Order Entry Panel: Access the trading interface for the asset you want to trade. 3. Select Limit Order: Choose "Limit Order" as your order type. 4. Enable Post Only: Locate the "Post Only" option within the order settings. This is usually a checkbox or a dedicated button. 5. Set Your Price: Enter your desired price for the limit order. 6. Specify Quantity: Enter the amount of the asset you want to buy or sell. 7. Review and Submit: Double-check your order details and submit the order.
Important Considerations for Beginners:
- Patience is Key: Post-only orders may not be filled immediately. Be patient and allow the market to reach your price.
- Order Book Analysis: Before placing a post-only order, analyze the order book to understand the current supply and demand. This can help you set a realistic price.
- Cancellation: If your order isn't filled after a reasonable period, consider cancelling it and adjusting your price.
- Risk Management: Always use proper risk management techniques, such as setting stop-loss orders, to protect your capital.
- Leverage with Caution: When using post-only orders in futures trading, be extremely careful with leverage. Understand the risks involved (as detailed here) and only use leverage that you are comfortable with.
Advanced Strategies with Post-Only Orders
Once you're comfortable with the basics, you can explore more advanced strategies:
- Order Layering: Placing multiple post-only orders at different price levels to create a wall of support or resistance.
- Spread Capture: Attempting to profit from the difference between the bid and ask price by placing post-only orders on both sides of the spread.
- Iceberg Orders: Breaking up a large order into smaller, hidden orders to minimize market impact. (Some platforms support this in conjunction with post-only orders.)
- Automated Trading Bots: Integrating post-only orders into automated trading bots to execute strategies efficiently.
Conclusion
Post-only orders are a valuable tool for traders of all levels, offering potential benefits in terms of lower fees, price improvement, and reduced slippage. While the concept is simple, mastering its application requires understanding the nuances of order books, fee structures, and risk management. By carefully selecting a platform like Binance or Bybit, and diligently practicing with small amounts, you can unlock the potential of post-only orders to enhance your trading efficiency and profitability.
