Spread

To obtain charts, make sure to add chart=True as the last parameter

Get underlying data

common.qa.spread(data: pandas.core.frame.DataFrame, window: int = 14) -> Tuple[pandas.core.frame.DataFrame, pandas.core.frame.DataFrame]

Standard Deviation and Variance

Parameters
----------
data: pd.DataFrame
    DataFrame of targeted data
window: int
    Length of window

Returns
-------
df_sd: pd.DataFrame
    Dataframe of rolling standard deviation
df_var: pd.DataFrame
    Dataframe of rolling standard deviation
