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 stands 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 passes, any part of the order filled remains filled while the rest is cancelled. Most good-'til-cancelled orders are in fact good-through-date orders because they generally expire 30 to 60 days after they are made, if they have not been filled, unless the investor reiterates them.
