We are starting with the Bollinger Bands ® contraction because a contraction often foreshadows a trend change or a trend continuation and is, therefore, the first important signal. Bollinger Bands ® do not lag (as much) because they always change automatically with the price action. When you hear someone say „95% confidence interval,“ it means they’re pretty certain (95% sure, to be exact) that the average price candle will fall within the range of the Bollinger Bands ®.

We used percentage bands and compared price action within the bands to the action of supply-demand tools like David Bostian’s Intraday Intensity to create trading systems. Bollinger Bands consist of three bands – an upper, middle and lower band – that are used to spot extreme short-term prices in a security. The upper band represents overbought territory, while the lower band can show you when a security is oversold. Most technicians will use Bollinger Bands in conjunction with other analysis tools to get a better picture of the current state of a market or security.
But seeing volatility dynamically change levels over time opened a window for innovation, I wondered if volatility itself couldn’t be used to set the width of trading bands. You can try out different standard deviations for the bands once you become more familiar with how they work. Bollinger Bands, a technical indicator developed by John Bollinger, are used to measure a market’s volatility and identify “overbought” or “oversold” conditions. Like other indicators, Bollinger Bands are best used in conjunction with other indicators, price analysis, and risk management as part of an overall trading plan.

A downside breakout might be confirmed with a price close below the support trend line as well as below the lower Bollinger Band. From a practical application perspective, Bollinger Bands are extremely flexible. For my option trading I had built some volatility models in an early spreadsheet program called SuperCalc. One day I copied a volatility formula down a column of data and noticed that volatility was changing over time.
Bollinger Bands can certainly be a confusing indicator, so understanding the underlying reasons behind price movements adds crucial context to Bollinger Band signals. Traders often interpret the breach of these bands as potential buying or selling signals. When prices touch or surpass the upper band, it may indicate an overbought condition, suggesting a possible reversal or correction. Conversely, touching or breaking the lower band might imply an oversold condition, signaling a potential upward price movement. Bollinger Bands present a framework for determining whether prices are high or low on a relative basis.
