Stock Bull, Bollinger bands are surrogates for confidence intervals. But they are not confidence intervals because the underlying assumption is that an econometric model exists for predicting future price movements. That is arrant nonsense. No such model exists. TAers wrap their ideas up in statistical jargon to try to impart a semblance of mathematical rigor to it, but it is all smoke and mirrors. A good analogy would be a psychic talking about the standard deviation of correct predictions. Sophisticated time series analysis of price and volume data have yet to show any predictive power to generated ad hoc models. TTFN, CTC
