Returns: : Returns 8 levels plus the range of all the levels.

get_bb_volatility(bb_highest, bb_lowest, ma_length, lookback)
: Provides a volatility indicator based on Bollinger Bands, and indicates wheather the volatility is increasing or decreasing.
Parameters:
bb_highest (float): (simple float): Top Bollinger Band on which to calculate the range.
bb_lowest (float): (simple float): Bottom Bollinger Band on which to calculate the range.
ma_length (simple int): (simple int): Length to use in the smoothing of Bollinger Bands range.
lookback (int): (simple int): Lookback period to identify a change in the Bollinger Bands range.
Returns: : Returns 8 levels plus the range of all the levels.
