# Stop-Limit Orders

> A stop-limit order becomes a limit order when its stop price trades. Learn how to set the stop and limit, when it protects you and when it can fail to fill.

A stop-limit order combines a stop order and a limit order. It has two prices: a **stop price** that activates the order, and a **limit price** that sets the worst price you will accept once it is active. When the market trades at your stop price, the order becomes a limit order at your limit price. It protects you from bad fills, but in exchange it can leave you without a fill at all.

## How it works

**Example: A sell stop-limit on a long position**
You own shares bought at $40.00. You place a sell stop-limit with a stop at $37.00 and a limit at $36.50.
**Orderly fall:** price trades at $37.00, the order activates as a sell limit at $36.50 and fills at about $36.95. You are out.
**Fast fall:** price drops from $37.20 to $36.10 in one move. The order activates at $37.00, but bids are already below $36.50, so nothing fills. The price keeps falling to $33.00, and you are still holding.

That second case is the central risk: a stop-limit can fail exactly when you most need protection.

## Stop vs stop-limit compared

| | Stop order | Stop-limit order |
|---|---|---|
| After trigger becomes | Market order | Limit order |
| Fill | Guaranteed once triggered (if trading continues) | Only at the limit or better |
| Price | Not guaranteed | Guaranteed, if filled |
| Danger | Slippage in fast markets and gaps | No exit in fast markets and gaps |

## Choosing the stop and limit prices

- **Stop price:** where your trade idea is wrong, as with any stop. See [Stop Loss Strategies](https://learn.tradelabsai.com/risk/stop-loss-strategies/).
- **Limit price:** how much slippage you will accept. A limit very close to the stop is likely to be skipped in a fast move. A limit further away fills more reliably but allows more slippage.

A common approach is to set the limit a set distance beyond the stop, such as a fraction of the asset's average true range, so it fills in normal conditions but not in a disorderly crash.

## When stop-limit orders make sense

- **Entering breakouts.** A buy stop-limit at $45.10 with a limit at $45.40 enters a breakout but refuses to chase a sudden spike to $47.
- **Thin markets** where a plain stop could fill at an absurd price on a brief air pocket.
- **Situations where no exit is acceptable,** for example a long term holding where you would rather hold through a flash crash than sell at a panic price.
- **Venues that require them.** Some crypto exchanges and extended hours sessions accept only limit based orders.

## When they are dangerous

- **As your main protective stop on a leveraged position,** where failing to exit can cause losses far beyond plan.
- **Around earnings and major news,** where prices can gap straight past both your stop and limit.
- **During halts,** after which a stock can reopen far below your limit. See [Trading Halts and Circuit Breakers](https://learn.tradelabsai.com/markets/trading-halts/).

**Watch out: Know what you are protecting against**
Ask: is my bigger risk a bad fill or no fill? For most protective stops, especially with leverage, no fill is worse. For entries, a bad fill is usually worse.

## Stop-limit orders in crypto

Many crypto exchanges offer stop-limit as the default stop type. Because crypto trades around the clock and can drop several percent in seconds during liquidation cascades, a tight limit can easily be skipped. Some exchanges also offer stop-market orders; know which you are placing.

## Frequently asked questions

### What is the difference between a stop order and a stop-limit order?

A stop order becomes a market order when triggered, guaranteeing an exit but not a price. A stop-limit becomes a limit order, guaranteeing a price but not an exit.

### Can a stop-limit order not execute?

Yes. If the price moves past your limit before the order can fill, it remains unfilled and you keep the position.

### What limit price should I use?

Far enough beyond the stop to fill in normal conditions but close enough to block extreme fills, often a small multiple of typical tick movement or a fraction of the ATR.
