You can see that for the most part, the price action was touching the lower band and the stock price fell from the $60 level in the dead of winter to its March position of around $10. In a couple of instances, the price action cut through the centerline (March to May and again in July and August), but for many traders, this was certainly not a buy signal as the trend wasn’t broken. When using Bollinger Bands®, designate the upper and lower bands as price targets. If the price deflects off the lower band and crosses above the 20-day average (the middle line), the upper band comes to represent the upper price target. In a strong uptrend, prices usually fluctuate between the upper band and the 20-day moving average.
Opening a position on June 13 allowed traders to enter right before the turnaround. Chart 5 shows Honeywell (HON) with an extended trading range in the area. There was a move to the upper band in May, but no breakout for a signal. Instead, HON clearly broke below the lower band to trigger a bearish signal in June 2007. Ideally, the Bollinger Bands indicator is usually narrow when there is no market volatility while its gap increases when market conditions change. Equity line with BBW filter.In short, limiting trend-following entries based on market volatility levels produced good results in our test.
On the right side, the Bollinger Bandwidth remained at elevated levels ahead of the next earnings. In turn, this threshold is defined by an input, which can be a preset exact value, or, for greater uniformity when backtesting multiple markets, a percentage of the last market close. The difference between the two bands can then be used as a filter for market entries; a narrowing of the width between the two bands is a condition for entry.

Commodity Channel Index Definition The commodity channel index (CCI) is an oscillator used to identify cyclical trends in a security. It’s another thing to size up one stock from another in terms of how it will respond to the bands. I just struggled to find any real thought leaders outside of John. I write this not to discredit trading with bands, just to inform you of how bands are perceived in the trading community. This level of mastery only comes from placing hundreds, if not thousands of trades in the same market. The stock could just be starting its glorious move to the heavens, but I am unable to mentally handle the move because all I can think about is the stock needs to come back inside of the bands.
Notice how the volume exploded on the breakout and the price began to trend outside of the bands; these can be hugely profitable setups if you give them room to fly. Another simple, yet bollinger bands bandwidth effective trading method is to fade stocks when they begin printing outside of the bands. We’ll take this one step further and apply a little candlestick analysis to this strategy.
The break of the lower Bollinger Band® signaled an oversold condition. On December 26, Yahoo again tested the lower band, but did not close below it. This would be the last time that Yahoo tested the lower band as it marched upward toward the upper band. Following the strategy, technical traders would enter their buy orders for NYX on June 13. The default setting for Band Width is a 20-Day simple moving
average with bands drawn at 2 standard deviations. Stock volatility can be challenging to forecast, but the Bollinger Band Width offers a less complex, visualized way to measure current volatility and estimate future shifts.

Traders can trade with the Bollinger Bandwidth indicator in several different ways but two of the most common ways to trade with this indicator involve breakout and reversal movements. Another good example of this is Snap, which you can see in the chart below. As you can see, the Bollinger Bandwidth remained in a tight range before the stock collapsed.
2 represents the number of standard deviations for the upper and lower band. BandWidth can be positioned above, below or behind the price plot. Bollinger Bands® gives traders an idea of where the market is moving based on prices. To calculate bands, you should first identify a simple moving average.
After periods of consolidation (low volatility), it is often noted that price tends move in an asserted fashion either up or down. Contrary to this, when the Bollinger Bandwidth indicator increases to relative highs (high volatility), this regularly signals a reversal in current trend. Because Bollinger Bands® are computed from a simple moving average, they weigh older price data the same as the most recent, meaning that new information may be diluted by outdated data.
A Bollinger Band® is a technical analysis tool defined by a set of trendlines. They are plotted as two standard deviations, both positively and negatively, away from a simple moving average (SMA) of a security’s price and can be adjusted to user preferences. Before we get to how they can do that, let’s talk about what they are and what they look like. A Bollinger Band consists of a middle band (which is a moving average) and an upper and lower band. These upper and lower bands are set above and below the moving average by a certain number of standard deviations of price, thus incorporating volatility. The general principle is that by comparing a stock’s position relative to the bands, a trader may be able to determine if a stock’s price is relatively low or relatively high.
It has been found that buying the breaks of the lower Bollinger Band® is a way to take advantage of oversold conditions. Usually, once a lower band has been broken due to heavy selling, the price of the stock will revert back above the lower band and head toward the middle band. This is the exact scenario this strategy attempts to profit from. The strategy calls for a close below the lower band, which is then used as an immediate signal to buy the stock the next day. Bollinger Bands® were created by John Bollinger in the ’80s, and they have quickly become one of the most commonly used tools in technical analysis.
