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
- Quoted prices can change quickly in fast markets.
- Costs and outcomes depend on liquidity, volatility, and order type.
- Always consider the spread when calculating entry and exit levels.
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.
