Sources:

Few internet resources on definitive definition. Request by Github user homily, issue #46

Calculation:

Default Inputs:: length=26, MA=’sma’
BIAS = (close - MA(close, length)) / MA(close, length): = (close / MA(close, length)) - 1

Args:

close (pd.Series): Series of ‘close’s length (int): The period. Default: 26 mamode (str): See `help(ta.ma)`. Default: ‘sma’ drift (int): The short period. Default: 1 offset (int): How many periods to offset the result. Default: 0

Kwargs:
