Market orders vs limit orders: what is the difference?
A market order buys or sells immediately at the best price available, so it is certain to fill but not at a certain price. A limit order names the price you will accept and fills only at that price or better, so the price is certain but the fill is not. Use market orders for urgency and limit orders for control.
Side by side
| Market order | Limit order | |
|---|---|---|
| When it fills | Immediately | Only if the price reaches your level |
| Price you get | The best available, which may differ from the quote | Your price or better |
| Certain to fill? | Yes, in a normal market | No |
| Main risk | Slippage | Missing the trade |
| Best for | Getting in or out now | Entering at a planned level |
Stop orders
A stop order waits until the price reaches a level and then becomes a market order. A stop loss is a stop order that closes a losing position. A buy stop above the price or a sell stop below it is used to enter on a breakout. Because it turns into a market order, a stop can fill beyond its level in a fast market.
| Order | Placed | Typical use |
|---|---|---|
| Buy limit | Below the current price | Buying a pullback |
| Sell limit | Above the current price | Selling a rally, or taking profit on a long position |
| Buy stop | Above the current price | Entering a breakout upwards |
| Sell stop | Below the current price | A stop loss on a long position, or a breakout downwards |
Slippage
Slippage is the gap between the price you expected and the price you got. Market and stop orders are exposed to it; limit orders are not. It is small in liquid markets during busy hours and can be large around news, at the weekend open, and in thin markets.
Which to use when
- Entering at a level you planned in advance: limit order.
- Entering on a breakout: stop order, accepting some slippage.
- Exiting a losing trade: a stop loss placed when you enter, every time.
- Exiting in an emergency: market order. Getting out matters more than the price.
- Taking profit at a target: limit order.
Options contracts work differently
When you buy a fixed-payout option, there is no order book to rest an order in. The broker quotes a price for the contract and you accept it or not. In Trade Pilot the order panel shows the payout Deriv quotes for your exact settings before you press Buy. On Multipliers you can attach a stop loss and a take profit, which close the position when the loss or profit reaches the amount you set.
Questions people ask
- Is a market order or a limit order better?
- Neither. A market order guarantees the fill and a limit order guarantees the price. Use the one that protects what matters more for that trade.
- Can a limit order fail to fill?
- Yes. If the price never reaches your level, or touches it without enough volume, the order stays unfilled and you miss the move.
- Is a stop loss guaranteed?
- A normal stop loss is not. It becomes a market order at your level and can fill at a worse price in a gap. Some brokers offer guaranteed stops for a fee.
- What is a stop-limit order?
- An order that becomes a limit order, not a market order, when the stop level is reached. It controls the price but may not fill at all in a fast move.
