Trading Limit

A trading limit, also known as a fluctuation limit, is the maximum amount that the price of a commodity future, option, or listed security may fluctuate during a trading session.

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.

Examples

  1. Commodity Futures: If a corn futures contract has a trading limit of $0.30 per bushel, the price of the contract cannot increase or decrease by more than $0.30 during a single trading session.
  2. Stock Market: A stock might have a trading limit of 10%, meaning the stock price cannot rise or fall by more than 10% from the previous closing price in one trading day.
  3. Options Markets: An options exchange might set a daily price change limit of 20% to curb excessive volatility.
