# Why was my stop loss triggered at a different price?

> Understand why stop orders may execute at a different price due to slippage or market gaps.

Your Stop Loss (SL) can sometimes execute at a price different from the exact trigger you set. This applies to both standalone stop orders and TP/SL orders set on your positions. This can happen due to how stop orders are activated and how the market moves, especially during volatility or when the underlying market reopens.

## How stop losses work on Roxom

When you place a Stop Loss, you choose:

1. **Trigger price**: the price that activates the order (can be Mark Price, Last Price, or Index Price)
2. **Order type**: market or limit order to actually close the position once triggered

<Info>
  **See all stop order types and triggers** in the [Order Types & Execution Rules](https://docs.roxom.com/rulebook/order-types-and-execution-rules/stop-market-order) section of our Rulebook.

## Why execution price can be different

1. **Trigger vs. execution**: Your SL is activated when the trigger price hits your set level. If you use a **market order**, it will execute at the best available price in the order book, which may be different from the trigger price

2. **Slippage during volatility**: In fast markets, the price can move quickly after triggering, especially with low liquidity

3. **Market closures and gaps**: If the underlying market is closed, the Mark Price may be frozen. When it reopens, a gap can occur, and your SL executes at the first available price

***

## Example

**Scenario:**

* SL trigger price: 0.0300 BTC (Mark Price)
* Mark Price drops to 0.0300 BTC → SL activates
* The best available price in the order book is 0.0298 BTC → execution happens there

***

## How to reduce unexpected fills

* **Use Limit SL orders**: If you want more control over execution price (but they may not fill if price moves too fast)
* **Check your trigger price type**: Always verify which trigger price type you selected (Mark Price, Last Price, or Index Price)
* **Be cautious before market reopen**: Be careful with large positions before the underlying market reopens

## Key takeaways

<Note>
  **Important points:**

  * Stop Loss trigger price ≠ guaranteed execution price
  * Slippage, liquidity, and market gaps can change the fill price
  * Choosing the right trigger type and order type can reduce surprises
