Definition
A trading limit is the maximum amount the price of a security, commodity, or futures contract can move up or down in a specified trading session. These limits serve as a regulatory measure to prevent extreme volatility and to maintain market stability. Trading limits are commonly set by exchanges and regulatory bodies and are designed to protect investors from sharp market movements.
