Good Through

Good Through

An order to a broker to buy or sell a security at a certain price whenever that price becomes available at any time before a certain date. Such an order is standing indefinitely until either the security is bought or sold at the specified price or the expiration date is met, or the investor cancels the order. The order may be partially filled; that is, if the expiration date comes and goes, any part of the order filled remains filled while the rest is cancelled. Most good-'til-cancelled orders are in fact good-through orders because they generally expire 30-60 days after they are made if they have not been filled, unless the investor reiterates them.
