SignalsRegister#

class qf_lib.backtesting.signals.signals_register.SignalsRegister[source]#

Bases: object

Used to save signals processed by the Position Sizer and to be able to later to analyze all signals generated by the model and to present them in a readable form.

abstractmethod get_signals() → QFDataFrame[source]#

Returns a QFDataFrame with all generated signals. The columns names consist of ticker names (in the following form: NameOfTicker@Model) and the rows are indexed by the time of signals generation (Signal objects do not store the timestamp).

Returns:: QFDataFrame with all generated signals
Return type:: QFDataFrame

abstractmethod get_signals_for_ticker(ticker: Ticker | None, alpha_model=None) → QFSeries[source]#

Returns a QFSeries with all generated signals for the given ticker. In case of a future ticker, it returns signals that were generated for any specific ticker, that belongs to the futures chain.

Parameters:

ticker (Ticker) – ticker for which the data frame should be generated
alpha_model – alpha model for which the generated signals should be returned (it checks whether the name of the alpha model matches the one in the signals using the str function)

Returns:

QFDataFrame with all generated signals

Return type:

QFDataFrame
