What a stop loss order is and what it is not
A stop loss converts into a market order (or in some variants a limit order) when a trigger price is reached. That means the fill price can differ from the trigger price, especially in fast or thin markets. This difference, often called slippage, matters because investors sometimes assume a stop loss guarantees an exit price. Standard stop losses generally do not. Some brokers offer guaranteed stop losses for an extra charge, but availability and cost vary and must be confirmed directly with the broker for your account type and region.
- A standard stop loss triggers an order; it does not guarantee the exit price.
- Slippage can occur around news events, market opens and gaps between sessions.
- Guaranteed stops, where offered, usually carry a fee or wider conditions.
- Stop orders behave differently on different products, so check per instrument.
