System and method for chart based order entry
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.
1. A system comprising:
a computing device, wherein the computing device comprises a processor, wherein the computing device is configured to:
display a movable order entry interface, wherein the movable order entry interface includes a plurality of price objects, wherein each price object corresponds to a price level, wherein the movable order entry interface is positioned at a location on a chart, wherein the chart includes historical market data corresponding to a tradeable object, wherein the historical market data is mapped to a plurality of values along a value axis;
determine a first plurality of price levels based on a value along the value axis associated with the location of the movable order entry interface with respect to the chart, wherein each price object of the plurality of price objects corresponds to one of the first plurality of price levels;
display, in response to an input signal from a user input device, the movable order entry interface at a new location on the chart in relation to an input location of the user input device;
determine, in response to the input signal from the user input device, a second plurality of price levels based on a new value along the value axis associated with the new location of the movable order entry interface with respect to the chart, wherein each price object of the plurality of price objects of the movable order entry interface is updated to correspond to one of the second plurality of price levels;
receive a selection of a price object of the plurality of price objects by the user input device; and
initiate, in response to receiving the selection of the price object, placement of a trade order based on the price level corresponding to the selected price object.
2. The system of claim 1 , wherein the plurality of price objects of the movable order entry interface is arranged in a circular shape.
3. The system of claim 1 , wherein the plurality of price objects of the movable order entry interface is arranged in an arc shape.
4. The system of claim 3 , wherein an angle corresponding to the arc shape is adjustable.
5. The system of claim 1 , wherein the plurality of price objects of the movable order entry interface is arranged to form a pie-chart interface.
6. The system of claim 1 , wherein the plurality of price objects of the movable order entry interface is arranged based on a user-defined shape.
7. The system of claim 1 , wherein the plurality of price objects of the movable order entry interface includes a plurality of bid price objects and a plurality of ask price objects.
8. The system of claim 7 , wherein the plurality of ask price objects correspond to different price levels than the plurality of bid price objects.
9. The system of claim 7 , wherein the trade order is an order to buy when the selected price object is one of the plurality of bid price objects, wherein the trade order is an order to sell when the selected price object is one of the plurality of ask price objects.
10. The system of claim 1 , wherein the movable order entry interface includes a plurality of quantity objects corresponding to a plurality of quantities.
11. The system of claim 10 , further including instructions executable to:
receive a selection of a quantity object of the plurality of quantity objects, wherein the trade order is for a quantity corresponding to the selected quantity object.
12. The system of claim 1 , further including instructions executable to:
receive a default quantity, wherein the trade order is for the default quantity.
13. The system of claim 1 , wherein the selection of the price object by the user input device includes at least one of: a selection of a key on a keyboard, depressing a mouse button, releasing a mouse button, and a touch of a touch-screen display.
14. The system of claim 1 , further including instructions executable to:
display market data in relation to the plurality of price objects of the movable order entry interface.
15. The system of claim 14 , wherein the market data includes current market depth for the price level corresponding to each of the plurality of price objects.
16. The system of claim 1 , further including instructions executable to:
display a working order indicator in relation to one of the plurality of price objects, wherein the working order indicator represents a working trade order at the price level corresponding to the one of the plurality of price objects.
17. The system of claim 1 , further including instructions executable to:
display traded volume in relation to at least one of the plurality of price objects.
18. The system of claim 1 , further including instructions executable to:
update the historical market data as market data is received.
19. The system of claim 1 , further including instructions executable to:
display a current highest bid price available for trading the tradeable object in relation to the plurality of price objects.
20. The system of claim 1 , further including instructions executable to:
display a current lowest ask price available for trading the tradeable object in relation to the plurality of price objects.
