classmethod by_instrument(instrument)[source]

Returns the ledger instance associated with the given instrument. If no ledger exists for the instrument, returns None.

Return type:: Ledger | None
Parameters:: instrument (Instrument)

classmethod calculate_instance_name_from_dict(data)[source]

Convert the provided keyword arguments to an instance name. This method should be implemented by subclasses to define how to derive the instance name.

Return type:: str
Parameters:: data (dict[str, Any])

property instance_name: str

instrument: Instrument

property length: int: Returns the number of transactions in the ledger. This is a computed property that provides the length of the transactions list.

model_config: ClassVar[ConfigDict] = {'extra': 'forbid', 'frozen': True}: Configuration for the model, should be a dictionary conforming to ConfigDict.

transactions: tuple[Transaction, ...]
