Dynamic functionality based on window characteristics

A method for providing dynamic functional states based on a window's characteristics, comprising:

• defining, by a computer device, a first functional state to correspond to a window having a first size, and a second functional state to correspond to the window having a second size based on resizing of the window;
• providing, by the computer device, the first functional state in relation to the window having a first size, the first functional state displays in the window having the first size market data using a first display type, wherein the first display type does not include order entry functionality;
• detecting, by the computer device, an input to resize the window;
• resizing, by the computer device, the window such that the size of the window has the second size that is different from the first size;
• determining, by the computer device, the second functional state based on the second size of the window;
• and
• in response to determining the second functional state, dynamically providing, by the computer device, a second functional state in relation to the window having the second size, wherein the second functional state displays in the window having the second size market data using a second display type that is different than the first display type, wherein the second display type includes order entry functionality, wherein the second display type sends an order message to buy or sell a tradeable object at an electronic exchange in response to a user action received in relation to the market data displayed in the window having the second size.
