Exchange Order Types and Market Structure
Understand market orders, limit orders, order books, spreads, slippage, and routing vocabulary.
Vocabulary-first analysis, reviewed against primary references where they are listed. Read our editorial methodology.
Orders describe trading instructions
An order is an instruction sent to a market venue. A market order prioritizes execution speed. A limit order sets a price boundary. A stop order or take-profit order may trigger after a condition is met.
These words are not predictions. They describe how an exchange or broker should attempt to execute an instruction.
The role of the order book
An order book lists available bids and asks. The bid-ask spread is the gap between the highest buyer and the lowest seller. A deep book usually has more available size near the current price; a thin book can move quickly when orders arrive.
Slippage and price impact appear when a trade consumes liquidity or moves through multiple price levels.
Routing and market design
Crypto markets can include centralized exchanges, decentralized exchanges, private order flow, aggregators, and routers. Each venue has a different way of matching orders or finding liquidity.
Vocabulary such as route splitting, private mempool, auction, and swap router belongs to this broader market-structure theme.
How this appears in the game
When several cards describe order instructions, they likely belong together. When cards describe where liquidity sits or how trades are routed, they may form a separate market-structure group.
The goal is to recognize the function of the word before trying to solve the board.
Applied reading
Why an order instruction is not an execution guarantee
A reader sees a market order described as immediate and a limit order described as price controlled. The missing detail is that every order interacts with available quotes. A market order may execute across several price levels, while a limit order may receive no fill at all. Speed, price boundary, and execution certainty are different objectives.
Venue selection adds another layer. A broker, exchange, or router may choose among markets with different spreads, fees, depth, and latency. The displayed price is therefore only one part of execution quality. The final result also depends on routing, available size, and how the market changes while the order is processed.
Concept boundaries
Terms that are easy to confuse
Market order
An instruction that prioritizes execution at available prices.
It does not promise the last displayed price.Limit order
An instruction with a maximum buy price or minimum sell price.
It controls a boundary but does not guarantee a fill.Spread
The gap between the best available bid and ask.
Spread is a quoted condition; slippage compares expected and actual execution.Price impact
Price movement associated with consuming available liquidity.
It is related to order size and depth, not just general market volatility.Market Depth
The quantity of orders available across multiple price levels.
Depth describes available size across the book; spread describes only the best bid and ask gap.Slippage
The difference between an expected execution result and the price actually received.
Slippage is measured from an expectation to a result; price impact describes how an order consumes liquidity.Knowledge check
Test the distinction, not the definition
Why can a market order fill at several prices?
The best quote may not contain enough size, so the remaining order moves through additional levels.
What trade-off does a limit order make?
It sets a price boundary but accepts the possibility of partial execution or no execution.
Why should a reader distinguish spread from slippage?
Spread is visible before an order, while slippage measures the difference between an expected and realized result.
