Stop Orders A stop order becomes a market order once a trigger price is reached, and it is used to enter or exit at defined levels.
Stop orders can help manage risk, but they are not guaranteed to fill at the trigger price. In fast markets or gaps, stops may fill at the next available price, leading to slippage. Related terms: Slippage, Gapping, Execution.
What it means
A stop order becomes a market order once a trigger price is reached, and it is used to enter or exit at defined levels.
Why it matters in live markets
In real markets, conditions like liquidity, volatility, and event risk can change quickly. That can affect quoted prices, spreads, and how orders fill. Understanding this term helps you interpret what you see on the platform and avoid incorrect assumptions when the market is moving fast.
Key points
- Focus on how the term affects price, cost, risk, or execution.
- Relationships can change across market regimes and sessions.
- Use the term to describe what you see, not to assume direction.
Example: A simple way to check your understanding is to apply the definition to a live quote, then ask how it affects cost, risk, or execution.
