Systems and methods for chart-based order entry are described. According to one example method a chart is used to display historical market data corresponding to a tradeable object. An order entry interface is displayed in relation to the chart. The order entry interface includes a plurality of price objects for selecting price levels to be used for trade orders to buy or sell the tradeable object. According to one example method, the price levels corresponding to the price objects depend on a location of the interface in relation to the chart, and as the interface is moved in relation to the chart, the price levels are automatically updated. Upon selection of the price level on the interface, a trade order to buy or sell is submitted to a matching engine at an electronic exchange.
