Calculation:

Default Inputs:: length=14, swma_length=4

SWMA = Symmetrically Weighted Moving Average numerator = SUM(SWMA(close - open, swma_length), length) denominator = SUM(SWMA(high - low, swma_length), length) RVGI = numerator / denominator

Args:

open_ (pd.Series): Series of ‘open’s high (pd.Series): Series of ‘high’s low (pd.Series): Series of ‘low’s close (pd.Series): Series of ‘close’s length (int): It’s period. Default: 14 swma_length (int): It’s period. Default: 4 offset (int): How many periods to offset the result. Default: 0

Kwargs:

fillna (value, optional): pd.DataFrame.fillna(value) fill_method (value, optional): Type of fill method

Returns:

pd.Series: New feature generated.
