An
order to a
broker in which the client instructs the a
broker to
execute only part of the order if necessary. This situation usually arises when the broker cannot find a corresponding order. For example, if an
investor makes an order to a
broker to
sell 1000
shares at a certain
price but there are only
buyers for 600 shares, the broker partially executes the order and looks for buyers for the remaining 400. The leftovers from an any-part-of order are called
leaves. This order contrasts with an
all-or-none order.
