(base_instrument=USD, **kwargs)[source]¶ Bases:

class
tensortrade.base.context.
TradingContext
(base_instrument=USD, **config)[source]¶ Bases:
collections.UserDict
A class for objects that put themselves in a Context using the with statement.
The implementation for this class is heavily borrowed from the pymc3 library and adapted with the design goals of TensorTrade in mind.
Parameters: - shared – A context that is shared between all components that are made under the overarching TradingContext.
- exchanges – A context that is specific to components with a registered name of exchanges.
- actions – A context that is specific to components with a registered name of actions.
- rewards – A context that is specific to components with a registered name of rewards.
- features – A context that is specific to components with a registered name of features.
Warning
If there is a conflict in the contexts of different components because they were initialized under different contexts, can have undesirable effects. Therefore, a warning should be made to the user indicating that using components together that have conflicting contexts can lead to unwanted behavior.

__enter__
()[source]¶ Adds a new context to the context stack.
This method is used for a with statement and adds a TradingContext to the context stack. The new context on the stack is then used by every class that subclasses Component the initialization of its instances.
