A trading interface is provided for displaying market data related to a
tradeable object being traded at an electronic exchange. According to one
example embodiment, market data related to a tradeable object is
displayed in relation to a value axis, such as a price axis. As new
market data is received, the displayed market data is updated and may be
repositioned so that a trader can view current market conditions in a
viewable portion of the interface. The interface also includes a number
of market movement indicators that assist a trader in tracking market
movement. These viewable references allow a trader to navigate and
immediately understand the "real" direction of the market activity
despite any underlying adjustment of the viewable area of the trading
interface.
