## Buying Limit

A buying limit is the maximum position size or value an investor can open, often determined by the broker based on the account's equity. It prevents the investor from exceeding their leverage capacity.

These limits are set to ensure the account remains stable and within the regulatory and risk parameters established by the broker.
