In crypto trading, one of the first things beginners encounter is the order book—a list of buy and sell orders waiting to be executed. To interact with this order book, traders use different types of orders such as market orders, limit orders, and stop orders.
Each order type works differently and has its advantages, disadvantages, and best-use cases. Knowing when to use a market order vs limit order vs stop order can be the difference between successful execution and unexpected losses.
This guide breaks down each type, shows how they work on platforms like Bitunix, and answers the most common questions traders ask about order types.
What Is an Order Book in Crypto?
An order book is a real-time list of buy and sell orders for a particular cryptocurrency on an exchange. It shows:
- Buy orders (bids): Prices and amounts buyers are willing to pay.
- Sell orders (asks): Prices and amounts sellers want to receive.
- Order depth: The total number of orders at each price point.
The order book is the foundation for how market orders, limit orders, and stop orders get executed.
What Is a Market Order?
A market order is an instruction to buy or sell immediately at the best available price in the order book.
- Buy Market Order: Fills instantly at the lowest available ask.
- Sell Market Order: Fills instantly at the highest available bid.
Best for: Speed and guaranteed execution.
Risk: Price slippage if liquidity is low or volatility is high.
Example: If BTC/USDT is showing $50,000, a market buy order will execute near $50,000, but depending on liquidity, the actual fill could be slightly higher.
What Is a Limit Order?
A limit order allows traders to set the exact price at which they are willing to buy or sell.
- Buy Limit: Placed below the current market price. Executes only if the price drops to that level.
- Sell Limit: Placed above the current market price. Executes only if the price rises to that level.
Best for: Controlling the entry/exit price.
Risk: The order may not fill if the price never reaches the limit.
Example: If BTC is at $50,000, you can set a buy limit at $48,000. It will only execute if the price falls to $48,000 or below.
What Is a Stop Order?
A stop order is an order that triggers once the market reaches a specified stop price.
There are two main types:
- Stop-Market Order: Converts into a market order once the stop price is hit. Execution is guaranteed, but the final price may vary.
- Stop-Limit Order: Converts into a limit order once the stop price is hit. Execution is not guaranteed, but it gives price control.
Best for: Risk management (stop-loss) and breakout strategies.
Example: You hold ETH at $3,000. You set a sell stop-market order at $2,800. If ETH drops to $2,800, the order triggers and sells at the next available price.
Market Order vs Limit Order vs Stop Order
| Feature | Market Order | Limit Order | Stop Order |
| Execution Speed | Instant | Only if price matches | Only if stop price is triggered |
| Price Control | No | Yes | Partial (stop-limit) |
| Best Use Case | Fast entry/exit | Buying dips, selling rallies | Stop-loss or breakout strategies |
| Risk | Slippage | No guarantee of fill | Non-execution (stop-limit) or slippage (stop-market) |
In short:
- Market order = fastest execution.
- Limit order = best price control.
- Stop order = risk management tool.
Limit vs Stop vs Stop-Limit
- Limit Order: Executes at a set or better price.
- Stop-Market Order: Triggers a market order when the stop price is reached.
- Stop-Limit Order: Triggers a limit order when the stop price is reached.
Stop price vs limit price:
- The stop price is the trigger.
- The limit price is the maximum/minimum price you’re willing to trade at once triggered.
Buy Limit vs Buy Stop | Sell Stop vs Sell Limit
- Buy Limit: Buy below current market price.
- Buy Stop: Buy above current market price (e.g., breakout entry).
- Sell Limit: Sell above current market price.
- Sell Stop: Sell below current market price (e.g., stop-loss).
Example:
- BTC trades at $50,000.
- A buy stop at $52,000 means buying if BTC breaks higher.
- A buy limit at $48,000 means buying if BTC dips lower.
When Should Traders Use Each Order?
- Market Orders:
- When execution speed is more important than price.
- During highly liquid market hours.
- Limit Orders:
- When aiming for a specific entry/exit price.
- In volatile markets to avoid slippage.
- Stop Orders:
- To protect profits (trailing stop).
- To prevent large losses (stop-loss).
- To enter trades on breakouts (buy stop).
Practical Examples
Market Order Example
You want to buy 100 USDT worth of BTC instantly. You place a market order, and it fills at the current best available price in the order book.
Limit Order Example
You want to buy ETH if it drops to $2,500. You place a buy limit at $2,500. If ETH hits that price, your order executes.
Stop Order Example
You are long on BTC at $40,000. To prevent losses, you place a sell stop-market order at $38,000. If BTC falls to $38,000, your order executes at the next market price.
