The present method and software provides a display for a trader in tradable instruments that shows the market price and market depth. The display dynamically updates with data received from an electronic exchange and centers on the market price. Upon the trader moving a cursor over a trade entering portion of the screen to make a trade, the price is held stationary and no longer centers on the market price so as to permit the trader to select a price and quantity for trading. The displayed data is still being updated in the stationary screen, however. The trade is made by the trader selecting a price and quantity on the display. Movement of the cursor away from the trade selecting area results in the display again automatically centering on the market price in the dynamic display mode.
