// According to Wikipedia and the internet:
// Bollinger Bands chart the price and volatility of a financial instrument over time
// and yield an "envelope" minimum and maximum and middle "bands" of moving averages
// which provide a relative definition of high and low market prices
// Prices are "high" at or near the upper band and "low" at or near the lower band.
// Bollinger Bands are considered useful for pattern recognition
