Args:

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 lensig (int): Signal Length. Like TradingView’s default ADX. Default: length scalar (float): How much to magnify. Default: 100 mamode (str): See `help(ta.ma)`. Default: ‘rma’ drift (int): The difference period. Default: 1 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.DataFrame: adx, dmp, dmn columns.
