Post-Only Orders: Spot & Futures – Which Platforms Support Them?

Post-Only Orders: Spot & Futures – Which Platforms Support Them?

Post-only orders are a powerful tool for traders aiming to minimize slippage and potentially benefit from maker fees. This article, geared towards beginners, will explain what post-only orders are, how they work in both spot and futures markets, and which popular platforms currently support them. We’ll analyze key features like order types, fee structures, and user interfaces, helping you choose the best platform for your trading strategy. We will also touch upon related concepts like derivatives and trading strategies to provide a broader understanding.

What are Post-Only Orders?

Traditionally, when you place an order on an exchange, it can be executed as either a *maker* or a *taker*.

• **Maker:** A maker order is one that isn't immediately filled and adds liquidity to the order book. Essentially, you're placing an order at a price not currently available, creating a new order for others to trade against. Makers typically receive a *maker fee rebate* – a payment from the exchange for providing liquidity.
• **Taker:** A taker order is one that is immediately filled by matching an existing order on the order book. Takers *take* liquidity from the market and usually pay a *taker fee*.

A **post-only order** is a specific type of order that *guarantees* it will be executed as a maker order. The exchange will not allow the order to be executed if it would become a taker order. If the order would be filled as a taker, it will simply be cancelled. This is crucial for traders who prioritize receiving maker fee rebates and avoiding the impact of immediate execution on price.

Why Use Post-Only Orders?

There are several key advantages to using post-only orders:

• **Lower Fees:** As mentioned, maker fees are often lower (or even negative – a rebate) than taker fees. Over time, these savings can significantly impact profitability, especially for high-frequency traders.
• **Reduced Slippage:** By avoiding immediate execution, post-only orders are less susceptible to slippage – the difference between the expected price of a trade and the actual price at which it is executed. This is particularly important for larger orders or volatile markets.
• **Improved Order Execution:** Post-only orders can help you get filled at a more favorable price, as you're not competing directly with other immediate buyers or sellers.
• **Strategic Order Placement:** They enable more deliberate order placement, allowing traders to strategically influence the order book.

Post-Only Orders in Spot vs. Futures Markets

The application of post-only orders differs slightly between spot and futures markets:

• **Spot Market:** In the spot market, you’re trading the underlying asset directly (e.g., buying Bitcoin with USD). Post-only orders here focus on minimizing fees and slippage when acquiring or selling the asset.
• **Futures Market:** The futures market involves trading contracts that represent an agreement to buy or sell an asset at a predetermined price on a future date. Post-only orders in futures, particularly perpetual futures, are often used in conjunction with sophisticated trading strategies like grid trading or arbitrage, where precise order placement and fee minimization are critical. Understanding the role of derivatives in the futures market is essential for effective trading. You can learn more about this at [1]. Moreover, techniques like Elliot Wave Theory Explained: Predicting Trends in BTC/USDT Perpetual Futures can be combined with post-only orders to optimize entry and exit points. [2]

Platform Support: A Comparative Analysis

Let's examine which popular platforms support post-only orders and how they implement the feature:

Binance

• **Support:** Binance *does* support post-only orders, but it’s not a straightforward toggle. It requires using the API or a third-party trading bot. There isn’t a built-in checkbox in the standard web interface.
• **Order Types:** Binance offers a wide array of order types including Limit, Market, Stop-Limit, and OCO (One Cancels the Other). However, achieving a post-only execution relies on carefully setting your limit price far enough away from the current market price.
• **Fees:** Binance has a tiered fee structure based on 30-day trading volume and BNB holdings. Maker fees can be as low as 0.0000% with VIP status and BNB discounts. Taker fees are generally higher.
• **User Interface:** The UI is generally user-friendly, but the lack of a dedicated post-only option makes it less convenient for beginners.
• **Beginner Priority:** Low. Requires more technical knowledge or the use of external tools.

Bybit

• **Support:** Bybit has a dedicated "Post Only" checkbox directly within its order placement interface, making it exceptionally user-friendly.
• **Order Types:** Bybit offers Limit, Market, Conditional, and Track Margin Mode orders. The post-only feature works seamlessly with Limit orders.
• **Fees:** Bybit's fee structure is competitive, with maker rebates available. The exact rebate amount depends on your trading volume and membership level.
• **User Interface:** Bybit's interface is clean and intuitive, and the post-only checkbox is clearly visible.
• **Beginner Priority:** High. The ease of use makes it ideal for beginners wanting to experiment with post-only orders.

OKX

• **Support:** OKX also supports post-only orders with a dedicated checkbox on the order form.
• **Order Types:** OKX provides a comprehensive suite of order types, including Limit, Market, Stop-Limit, Trailing Stop, and Advanced Conditional Orders.
• **Fees:** OKX’s fee structure is tiered, with maker rebates available for qualifying traders.
• **User Interface:** OKX’s interface can be a bit overwhelming for beginners due to the sheer number of features but the post-only option is easily located.
• **Beginner Priority:** Medium. The abundance of features might be confusing initially, but the post-only functionality is straightforward.

KuCoin

• **Support:** KuCoin *does not* currently offer a dedicated post-only order type. Similar to Binance, achieving a post-only execution requires careful limit order placement.
• **Order Types:** KuCoin offers Limit, Market, Stop-Limit, and Trailing Stop orders.
• **Fees:** KuCoin’s fee structure is tiered based on 30-day trading volume.
• **User Interface:** KuCoin's interface is relatively simple and easy to navigate.
• **Beginner Priority:** Low. The lack of a post-only option makes it less appealing for traders specifically seeking this functionality.

Kraken

• **Support:** Kraken supports post-only orders through its API and advanced order settings. A dedicated checkbox is not available in the standard web interface.
• **Order Types:** Kraken offers Limit, Market, Stop-Loss, and Take-Profit orders.
• **Fees:** Kraken's fee structure is tiered based on 30-day trading volume.
• **User Interface:** Kraken's interface is functional but can be less intuitive than some other platforms.
• **Beginner Priority:** Low. Requires API knowledge or advanced order setting familiarity.

Bitget

• **Support:** Bitget provides a "Post Only" option directly in the order interface, similar to Bybit and OKX.
• **Order Types:** Limit, Market, Conditional, and TP/QL orders are available.
• **Fees:** Bitget offers a tiered fee system with maker rebates.
• **User Interface:** The UI is modern and user-friendly.

Platform Comparison Table

Platform	Post-Only Support	User Interface	Beginner Priority

Important Considerations for Beginners

• **Price Slippage:** Always consider potential price slippage when placing post-only orders. If the market moves rapidly, your order might not be filled at the expected price, even though it's a maker order.
• **Order Book Depth:** The depth of the order book (the number of buy and sell orders at different price levels) significantly impacts the likelihood of your post-only order being filled. A deeper order book increases the chances of a fill.
• **Volatility:** In highly volatile markets, post-only orders may take longer to fill or may not be filled at all.
• **Testing:** Start with small order sizes to test the post-only functionality on your chosen platform before committing larger amounts of capital.
• **Understanding Futures:** If you're venturing into futures trading, a solid understanding of concepts like margin, leverage, and liquidation is crucial. Furthermore, exploring resources like those found at [3] can provide valuable context, even if you’re not trading energy futures directly.

Conclusion

Post-only orders are a valuable tool for traders seeking to minimize fees and slippage. While not all platforms offer a dedicated post-only option, platforms like Bybit, OKX, and Bitget provide a user-friendly experience with a simple checkbox. Beginners should prioritize these platforms for ease of use and experimentation. Remember to carefully consider market conditions, order book depth, and potential slippage before placing any post-only order. Thorough research and practice are key to successfully incorporating this strategy into your trading plan.
