An
order to
buy a
stock at or below a specified price or to sell a stock at or above a specified price. For instance, you could tell a
broker "
buy me 100
shares of XYZ Corp at $8 or less" or to "sell 100 shares of XYZ at $10 or better." The customer specifies a price and the order can be
executed only if the
market reaches or betters that price. A conditional
trading order designed to avoid the danger of adverse unexpected price changes.
