    Defined by John Bollinger in the 80s. It measures volatility by defining
    upper and lower bands at distance x standard deviations

    Formula:
      - midband = SimpleMovingAverage(close, period)
      - topband = midband + devfactor * StandardDeviation(data, period)
      - botband = midband - devfactor * StandardDeviation(data, period)
