Limit vs market order in crypto: fees, slippage and fills
Crypto orders work like stock orders, with three twists: fees depend on the order type, small coins can have thin order books, and the market never closes.
The short answer
A Market order fills now, at the best prices in the Order book. On a thin coin, it can eat through several price levels.
A Limit order fills only at your price or better. It may wait, or never fill.
In crypto, the order type often changes your fee too. Many exchanges charge less to orders that wait in the book (makers) than to orders that fill right away (takers).
Our general guide, market vs limit order, covers the basics. This page is about what's different in crypto.
Side by side
| Market order | Limit order | |
|---|---|---|
| Fills | Right away | Only at your price or better |
| Usual fee role | Taker (often higher) | Maker if it rests in the book (often lower) |
| Slippage risk | Yes, can be large on thin coins | None past your price |
| Missed-trade risk | Very low | Yes |
| Partial fills | Rare on big coins | Common |
| Best for | Getting out fast; very liquid pairs | Planned entries, targets, thin coins |
Fee schedules differ by exchange and often by your monthly volume. Check yours.
Maker vs taker, in plain words
- A taker takes an order that's already waiting in the book. A market order is always a taker.
- A maker adds a new order to the book that others can fill later. A limit order that doesn't fill right away is a maker.
Exchanges like makers because they add buyers and sellers. So maker fees are often lower.
A math example. You buy $1,000 of a coin.
| Fee rate | Fee |
|---|---|
| 0.10% (example maker rate) | $1.00 |
| 0.40% (example taker rate) | $4.00 |
Round trip, buying and selling, doubles it. A math example, not a promise. Your exchange's real rates may be higher or lower.
Note: a limit order priced past the market (a buy limit above the ask) fills right away. That makes it a taker. Some exchanges offer a "post-only" option that cancels the order instead of letting it fill as a taker.
Slippage on thin coins
Big coins like bitcoin usually have deep books. A small market order fills close to the price you see.
Small coins can be thin. Here's a picture in words. The book shows:
- 100 coins for sale at $1.00
- 200 coins at $1.05
- 500 coins at $1.15
You send a market order for 500 coins. You get 100 at $1.00, 200 at $1.05 and 200 at $1.15. Your average price is about $1.08, not $1.00. That gap is Slippage.
A limit order at $1.00 would have filled 100 coins and waited for the rest.
The 24/7 twist
Crypto never closes. That changes a few things:
- Quiet hours exist. Weekends and late nights can have thinner books and wider spreads.
- Orders can sit for days. A good-till-canceled limit order may fill at 4 am on a Sunday. Be sure you still want it.
- Stops matter at night too. A move while you sleep doesn't wait.
A simple habit: before any order, look at the spread and the book depth. If the gap between buy and sell prices is wide, use a limit order, or trade smaller.
Which fits you?
- Entering a planned trade at a level? A limit order waits there for you and may cost less in fees.
- Getting out because your plan says so? A market order is fine on a liquid coin. Speed matters more than a fee difference.
- Trading a small, thin coin? Limit orders protect you from walking up the book.
- Holding long-term and buying monthly? Fees add up over time. Limit orders can trim them.
Always plan the stop with the entry. The position size calculator sets the size from it.
Common mistakes
- Market orders on thin coins. The average fill can be far from the screen price.
- Forgetting old limit orders. They can fill days later, after you've changed your mind.
- Chasing a limit order up. If price left, the setup did too. See FOMO trading.
- Ignoring fees on small trades. On many small trades, fees can be a big share of the result.
Questions
Should I use a limit or market order for crypto?
Many traders enter with limit orders, which control the price and often pay lower maker fees, and exit with market orders on liquid coins when speed matters.
What are maker and taker fees?
A maker adds an order to the book that waits to be filled; a taker fills an order already waiting. Many exchanges charge makers less than takers.
Why did my crypto market order fill at a worse price?
The order book wasn't deep enough at the best price, so your order filled at several levels. That difference is slippage, and it's bigger on thin coins.
Can a limit order be a taker?
Yes. If your limit price crosses the market, it fills right away and counts as a taker. A post-only option, where offered, prevents that.
