An
order placed with a brokerage to buy or sell a security at a particular
price to close all or part of your position. Many brokers only
allow limit orders to be placed a set distance away from the current
market price.
Limit
orders are traditionally used to close a position once a security
trades at a target price, usually when the position is in profit.
Limit orders can be used to close out all or only part of a position.
