Fill or Kill Orders: A Beginner's Guide
Welcome to the world of cryptocurrency trading! As you start your journey, you'll encounter different types of orders you can place on a cryptocurrency exchange. One of these is the "Fill or Kill" order. This guide will explain what a Fill or Kill order is, how it works, and when you might want to use it. It's designed for complete beginners, so we'll keep things simple and practical.
What is a Fill or Kill (FOK) Order?
"Fill or Kill" (often shortened to FOK) is a type of order that instructs your exchange to execute your entire order *immediately* at the specified price, or cancel the order altogether. It’s an “all-or-nothing” approach. If the exchange can’t find enough buyers or sellers willing to trade at your price *right now*, the order simply doesn't go through. No partial fills are allowed.
Think of it like this: You want to buy 10 Bitcoin at $30,000 each. You place a Fill or Kill order. If there are at least 10 Bitcoin available for sale at $30,000 or lower, the exchange will buy all 10. If there aren’t, the order is cancelled, and you don’t buy any Bitcoin.
Key Terms Explained
- **Order:** An instruction to buy or sell a cryptocurrency. See Order Types for more detail.
- **Execute:** To complete a trade.
- **Price:** The amount you're willing to pay (when buying) or receive (when selling) for a cryptocurrency.
- **Cancel:** To remove an order that hasn't been filled.
- **Partial Fill:** When only a portion of your order is executed. This *doesn't* happen with a Fill or Kill order.
- **Liquidity:** How easily a cryptocurrency can be bought or sold without significantly affecting its price. High liquidity means there are many buyers and sellers available.
How Does a Fill or Kill Order Work?
Let's use an example on Register now Binance Futures:
1. **Select the Trading Pair:** Choose the cryptocurrency you want to trade (e.g., BTC/USDT). 2. **Choose "Limit" Order:** FOK orders are often implemented as a type of limit order. 3. **Set the Price:** Enter the price you want to buy or sell at. 4. **Enter the Quantity:** Specify the amount of cryptocurrency you want to trade. 5. **Select "Fill or Kill":** Look for the "Order Type" or "Time in Force" option and select “Fill or Kill”. (The exact wording may vary slightly between exchanges.) 6. **Submit the Order:** Once you've confirmed the details, submit your order.
The exchange will then attempt to match your order with existing orders in the order book. If a full match is found at your price, the trade is executed. Otherwise, the order is cancelled. You can find more information on order books in Understanding Order Books.
When to Use a Fill or Kill Order
FOK orders are best used in specific situations:
- **Large Orders:** If you're placing a large order and need to ensure it's filled entirely to achieve your trading strategy.
- **Price Sensitivity:** When you absolutely need to buy or sell at a specific price and are unwilling to accept a worse price.
- **High Liquidity:** FOK orders work best when the market has high trading volume and good liquidity.
- **Avoiding Slippage:** Slippage occurs when the price changes between the time you place an order and the time it's executed. FOK orders minimize slippage by ensuring the full order is filled at the specified price.
