// "Bollinger Bands were developed by John Bollinger and are envelopes that
// are plotted at two (2) standard deviation levels above and below a moving
// average. The CCT Bollinger Band Oscillator reconfigures the classic bands.
// The new indicator constructs two (2) parallel lines instead of the erratic
// envelopes. These parallel lines represent a measurement of two (2) standard
// deviations from the mean and are assigned zero and 100 on the chart. The
// indicator represents the price as it travels above and below the mean (50%)
// and outside the two standard deviations (zero and 100). Penetration of the
// upper or lower band represents overbought and oversold conditions. When
// using the CCT Bollinger Band Oscillator, “failure
// swings” and “divergences” can lead to
// significant reversals."
