Dynamically activating and deactivating one or more elements of a trading tool

1. A non-transitory computer readable medium having instructions stored thereon, which when executed by a processor cause the processor to carry out acts comprising:

displaying, by a computer device, a trading screen having a display of a trading tool where the trading tool has a trading tool element that is configured to perform at least one trade action and has a value and a location that are determined according to market data received from an electronic exchange;

determining, by the computer device, whether the trading tool element should be active or inactive based on trade data and the market data where the trading tool element, when active, is operable to perform the at least one trade action and, when inactive, is inoperable to perform the at least one trade action;

dynamically, by the computer device, activating or deactivating the trading tool element in response to determining whether the trading tool element should be active or inactive; and

changing, by the computer device, the display of the trading tool element to indicate whether the trading tool element is active or inactive.

2. The non-transitory computer readable medium of claim 1 where dynamically activating or deactivating the trading tool element includes switching an operation state of the trading tool element between active and inactive depending on whether the trading tool element should be active or inactive.

3. The non-transitory computer readable medium of claim 1 where the trade data is risk management data that defines a risk limit.

4. The non-transitory computer readable medium of claim 3 where the trading tool element is active when performing the at least one trade action does not exceed the risk limit and is inactive when performing the trade action associated with the trading tool element substantially equals or exceeds the risk limit.

5. The non-transitory computer readable medium of claim 1 where the trade data is trading methodology data that defines a trading methodology.

6. The non-transitory computer readable medium of claim 5 where the trading methodology is defined by a user to ensure that the trader performs trade actions in accordance with the trading methodology.

7. The non-transitory computer readable medium of claim 1 where changing the display of the trading tool element includes graying out the trading tool element to indicate when the trading tool element is inactive.

8. The non-transitory computer readable medium of claim 1 where the trade data does not include availability data that defines availability of certain components of an electronic trading system.

9. A non-transitory computer readable medium having instructions stored thereon, which when executed by a processor cause the processor to carry out acts comprising:

receiving, by a computer device from an electronic exchange, market data associated with a trading tool element where the trading tool element is a selectable option for performing at least one trade action and has a value and a location that are determined according to the market data;

determining, by the computer device, whether the trading tool element is selectable based on trade data and the market data;

switching, by the computer device, the trading tool element between an active state and an inactive state in response to determining whether the trading tool element is selectable where switching includes configuring the trading tool element to be selectable for performing the at least one trade action when in the active state and configuring the trading tool element such that it is not selectable for performing the at least one trade action when in the inactive state; and

displaying, by the computer device, the trading tool element such that the trading tool element indicates whether it is in the active state or the inactive state.

10. The non-transitory computer readable medium of claim 9 where switching includes dynamically activating or deactivating depending on whether the trading tool element should be in the active state or the inactive state.

11. The non-transitory computer readable medium of claim 9 where the trade data is risk management data.

12. The non-transitory computer readable medium of claim 9 where the trade data is trading methodology data.

13. The non-transitory computer readable medium of claim 9 where displaying includes graying out the trading tool element when the trading tool element is in the inactive state.

14. The non-transitory computer readable medium of claim 13 where graying out includes changing the display of the trading tool to indicate that the trading tool element is in the inactive state, yet allowing information being represented by the trading tool element to be visible.

15. A non-transitory computer readable medium having instructions stored thereon, which when executed by a processor cause the processor to carry out acts comprising:

receiving, by a computer device, at least one variable;

receiving, by the computer device, at least one rule for determining whether a trading tool should be activated or deactivated where the at least one rule is based on trade data and wherein the trading tool has a value and a location that are determined according to market data received from an electronic exchange;

analyzing, by the computer device, the at least one rule, the market data, and the at least one variable to determine whether to switch an operation state of a trading tool element between an active state and an inactive state, the trading tool element being operable to perform a trading action in the active state and being inoperable to perform the trading action in the inactive state; and

switching, by the computer device, the operation state of the trading tool element between the active state and the inactive state in response to analyzing.

16. The non-transitory computer readable medium of claim 15 where the acts further include changing, by the computer device, a display of the trading tool element to indicate whether the trading tool element is active or inactive.

17. The non-transitory computer readable medium of claim 16 where changing the display includes graying out the trading tool element, such that data associated with the trading tool element is visible.

18. The non-transitory computer readable medium of claim 17 where the data associated with the trading tool element is updated even when the trading tool element is inactive.

19. The non-transitory computer readable medium of claim 17 where graying out includes changing a shade or color of the trading tool element.

20. The non-transitory computer readable medium of claim 15 where analyzing comprises determining at least one of whether an option that is too risky, whether an option is contrary to a particular trading strategy, and whether an option would result in a loss of money.
