1. 1. Post-Only Orders: Improving Execution on Solana Exchanges

As the Solana ecosystem continues to flourish, efficient trading becomes paramount. While simply buying and selling cryptocurrency seems straightforward, understanding advanced order types can significantly improve your execution price and reduce slippage. One such order type is the “post-only” order. This article will break down post-only orders, explaining how they work, why they’re beneficial, and how they’re implemented on popular exchanges. We’ll also provide guidance for beginners navigating the world of Solana trading.

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.” A *taker* immediately matches an existing order on the order book. A *maker* adds liquidity to the order book by placing an order that isn’t immediately filled, awaiting a matching counter-order. Makers generally receive lower fees than takers, incentivizing them to provide liquidity.

However, simply placing a limit order doesn’t *guarantee* you’ll be a maker. If your limit order price is within the current bid-ask spread, it will likely be executed immediately as a taker. This is where post-only orders come in.

A post-only order instructs the exchange to *only* execute your order if it can be placed as a maker. If your order would be executed as a taker, it will be rejected. This ensures you always benefit from lower maker fees and potentially better pricing by avoiding immediate execution in a fast-moving market. Understanding the difference between Market Orders vs. Limit Orders in Futures is crucial before diving into post-only orders.

Why Use Post-Only Orders?

There are several compelling reasons to utilize post-only orders, particularly for active traders:

• **Reduced Fees:** Maker fees are typically significantly lower than taker fees. Over time, these savings can add up, especially for high-frequency traders.
• **Better Execution Prices:** By avoiding immediate execution, you're less susceptible to being filled at the worst available price during rapid price swings.
• **Avoidance of Front-Running:** While not foolproof, post-only orders can help mitigate the risk of malicious actors "front-running" your orders – anticipating your trade and executing their own to profit from the price movement.
• **Control Over Order Type:** You explicitly dictate that your order contributes to liquidity rather than taking it, aligning with a market-making strategy.
• **Improved Slippage Control:** Slippage refers to the difference between the expected price of a trade and the price at which it’s actually executed. Post-only orders can help minimize slippage by ensuring your order isn't filled at a rapidly changing price.

Post-Only Orders on Popular Exchanges

Let’s examine how post-only orders are implemented on some of the most popular cryptocurrency exchanges, focusing on features relevant to beginners. It's also vital to choose the Best Exchanges for 2024 based on your individual needs.

• **Binance:** Binance offers a “Post Only” checkbox within its trading interface. When checked, your limit order will only be executed if it rests on the order book as a maker order. Binance also provides detailed fee schedules, clearly outlining the maker/taker fee differences. Their user interface is generally considered beginner-friendly, but can be overwhelming at first. See How to Get Started with Cryptocurrency Exchanges Without Overwhelm for guidance.
• **Bybit:** Bybit also features a “Post Only” option when placing limit orders. Bybit is known for its derivatives trading and offers competitive fees. Their interface is more geared towards experienced traders, but they provide comprehensive educational resources.
• **OKX:** OKX provides a similar “Post Only” setting. OKX boasts a wide range of trading features and supports various order types, including advanced conditional orders. Conditional Orders: Spot & Futures – Beyond Basic Buy/Sell.
• **Kraken:** Kraken generally requires using API keys and advanced order settings to implement a strict post-only strategy. This is less accessible to beginners.
• **FTX (defunct):** While FTX is no longer operational, it was a pioneer in offering post-only orders and demonstrated their effectiveness.

Understanding Order Types: A Quick Refresher

Before delving deeper into post-only orders, let’s quickly review key order types:

• **Market Order:** Executes immediately at the best available price. Simple, but prone to slippage. See Market Orders, Limit Orders & More: Futures Order Types.
• **Limit Order:** Executes only at a specified price or better. Offers price control but may not be filled if the price doesn’t reach your limit. See Limit orders.
• **Stop-Limit Order:** Combines a stop price and a limit price. Activated when the price reaches the stop price, then executes as a limit order. Stop-Limit Orders: Spot vs. Futures Differences on Top Exchanges.
• **Stop-Market Order:** Similar to a stop-limit order, but executes as a market order once the stop price is reached. Guaranteed execution, but potentially at a worse price.

Post-only orders are typically used *in conjunction* with limit orders. You set a limit price, and the “post-only” function ensures it’s only executed as a maker order.

Fees and Considerations

Exchange fees are a crucial aspect of trading. Here’s a general overview:

• **Maker Fees:** Typically 0.0% to 0.10%
• **Taker Fees:** Typically 0.05% to 0.25%

These fees vary significantly between exchanges and are often tiered based on trading volume. Always consult the specific exchange’s fee schedule.

• • Important Considerations:**

• **Order Rejection:** If your post-only limit order would be executed as a taker, it will be *rejected*. This can be frustrating if you urgently need to enter or exit a position.
• **Liquidity:** In markets with low liquidity, your post-only order may remain unfilled for an extended period.
• **Price Movement:** Rapid price movements can invalidate your limit price, leading to order rejection.
• **Exchange Specifics:** Each exchange implements post-only orders slightly differently. Familiarize yourself with the specific settings and limitations of your chosen platform.
