Usage

>>> vbt.TRENDLB.run(ohlcv['High'], ohlcv['Low'], up_th=0.2, down_th=0.2).plot().show()

run class method

    short_name='trendlb',
    hide_params=None,
    hide_default=True,
    **kwargs
)

Run TRENDLB indicator.

  • Inputs: high, low
  • Parameters: up_th, down_th, mode
  • Outputs: labels

Pass a list of parameter names as hide_params to hide their column levels, or True to hide all. Set hide_default to False to show the column levels of the parameters with a default value.

Other keyword arguments are passed to IndicatorBase.run_pipeline.

run_combs class method

TRENDLB.run_combs(

    param_product=False,
    comb_func=itertools.combinations,
    run_unique=True,
    short_names=None,
    hide_params=None,
    hide_default=True,
    **kwargs
)

Create a combination of multiple TRENDLB indicators using function comb_func.

  • Inputs: high, low
  • Parameters: up_th, down_th, mode
  • Outputs: labels

comb_func must accept an iterable of parameter tuples and r. Also accepts all combinatoric iterators from itertools such as itertools.combinations. Pass r to specify how many indicators to run. Pass short_names to specify the short name for each indicator. Set run_unique to True to first compute raw outputs for all parameters, and then use them to build each indicator (faster).

Other keyword arguments are passed to TRENDLB.run.

Note

This method should only be used when multiple indicators are needed. To test multiple parameters, pass them as lists to TRENDLB.run.

up_th_list class property

List of up_th values.
