TradingStrategy

class scml.scml2020.TradingStrategy(*args, **kwargs)

Bases: object

Base class for all trading strategies.

Provides:

• inputs_needed (np.ndarray): How many items of the input product do I need to buy at every time step (n_steps vector). This should be read but not updated by the NegotiationManager.

• outputs_needed (np.ndarray): How many items of the output product do I need to sell at every time step (n_steps vector). This should be read but not updated by the NegotiationManager.

• inputs_secured (np.ndarray): How many items of the input product I already contracted to buy (n_steps vector) [out of input_needed]. This can be read but not updated by the NegotiationManager.

• outputs_secured (np.ndarray): How many units of the output product I already contracted to sell (n_steps vector) [out of outputs_secured] This can be read but not updated by the NegotiationManager.

Hooks Into:

• init

• internal_state

Remarks:

• Attributes section describes the attributes that can be used to construct the component (passed to its __init__ method).

• Provides section describes the attributes (methods, properties, data-members) made available by this component directly. Note that everything provided by the bases of this components are also available to the agent (Check the Bases section above for all the bases of this component).

• Requires section describes any requirements from the agent using this component. It defines a set of methods or properties/data-members that must exist in the agent that uses this component. These requirement are usually implemented as abstract methods in the component

• Abstract section describes abstract methods that MUST be implemented by any descendant of this component.

• Hooks Into section describes the methods this component overrides calling super () which allows other components to hook into the same method (by overriding it). Usually callbacks starting with on_ are hooked into this way.

• Overrides section describes the methods this component overrides without calling super effectively disallowing any other components after it in the MRO to call this method. Usually methods that do some action (i.e. not starting with on_) are overridden this way.
