Types of Orders: Market Orders

This article discusses Market Orders within the context of crypto futures trading.

Definition

A market order is an instruction to buy or sell a futures contract immediately at the best available current market price. Market orders prioritize speed of execution over price certainty. When a trader submits a market order, the exchange attempts to fill that order instantly using the existing limit orders in the order book.

Why it matters

Market orders are crucial for traders who need immediate entry into or exit from a position. They are essential when volatility is high or when a trader needs to react instantly to breaking news or a sudden market shift, often used when implementing strategies like those involving How to Trade Futures with a Breakout Strategy. However, because they execute immediately, they bypass the control over the exact execution price offered by other order types, such as limit orders.

How it works

Futures exchanges maintain an Order Book, which lists all outstanding buy (bid) and sell (ask) orders that have not yet been executed.

When a trader places a **Market Buy Order**: 1. The order sweeps through the sell side (the ask side) of the order book. 2. It executes against the lowest ask price first, then the next lowest, and so on, until the entire order quantity is filled.

When a trader places a **Market Sell Order**: 1. The order sweeps through the buy side (the bid side) of the order book. 2. It executes against the highest bid price first, then the next highest, until the entire order quantity is filled.

The final price at which the entire order is filled is the *average execution price*. If the order size is large relative to the depth of the order book, the execution price can vary significantly across the different price levels it consumes. This variation is known as Slippage.

Practical examples

Consider a perpetual [[BTC futures contract]] where the current best bid and ask prices are:

• Best Bid: $60,000 (Quantity: 5 contracts)
• Best Ask: $60,005 (Quantity: 10 contracts)
• Second Best Ask: $60,010 (Quantity: 20 contracts)

1. **Placing a Market Buy Order for 8 Contracts:**

   *   The first 5 contracts execute at $60,005.
   *   The remaining 3 contracts execute at the next available price, $60,010.
   *   The trader receives an average execution price somewhere between $60,005 and $60,010, depending on the exact volume filled at each level.

2. **Placing a Market Sell Order for 2 Contracts:**

   *   The entire order executes immediately against the best bid price of $60,000.
   *   The execution price is exactly $60,000.

Common mistakes

A frequent mistake for beginners is using market orders in thinly traded or volatile markets. In these conditions, a large market order can result in significant negative slippage, meaning the execution price is substantially worse than the price quoted just moments before the order was submitted. Traders unfamiliar with the Fee Structures for Futures might also be surprised by the total cost when a market order crosses multiple fee tiers due to slippage.

Safety and Risk Notes

Market orders guarantee execution but do not guarantee price. Traders must be aware of the current market liquidity before using a market order, especially when dealing with significant contract sizes or when using high levels of 2024 Crypto Futures: A Beginner’s Guide to Leverage and Margin. Low liquidity increases the risk of adverse price movement upon execution. Always monitor the order book depth when considering a market order.
