What Are Bollinger Bands And How Do They Indicate A Stock’s Next Move? Creator Explains All Video IBD

This is just another example of why it’s important to pair Bollinger Bands with other indicators and not use it as a standalone tool. Essentially, you have an actual reading of the volatility of a security. You can then look back over months or years to see if there are any repeatable patterns of how price reacts when it hits extremes. Instead, I want to center this piece of the article on how you can use bands to trade bitcoin. Not exiting your trade can almost prove disastrous as three of the aforementioned strategies are trying to capture the benefits of a volatility spike. Like any other trade signal, you will need to exit your position without reservation.

  • Notice how BandWidth tracks the Standard Deviation (volatility) – both rise and fall together.
  • The Bollinger Bands Width will increase during a period of high volatility.
  • Bollinger Bands %B indicator is derived from the simple Bollinger Band indicator.
  • Bollinger Band calculates deviation as the square root of the variance.
  • This approach will work well in sideways markets and will also have a high winning percentage.
  • This is an example of combining Bollinger Bands with a momentum oscillator for trading signals.

Use caution and always consult your accountant, lawyer or professional advisor before acting on this or any information related to a lifestyle change or your business or finances. Phases of flat calm, where volatility is very low, are usually believed to be followed by sudden movements that indicate a volatility explosion. In the chart above, you can see that in conjunction with the collapse of the asset’s price, a sharp change in volatility occurs. A tag of the upper Bollinger Band is NOT in-and-of-itself a sell signal. A tag of the lower Bollinger Band is NOT in-and-of-itself a buy signal.

What Is Bollinger BandWidth?

Settings can be adjusted to suit the characteristics of particular securities or trading styles. Most stock charting applications use a 20-period moving average for the default settings. The upper and lower bands are then a measure of volatility to the upside and downside. They are calculated as two standard deviations from the middle band. The bands are used to generate signals for securities that are oversold or overbought.

  • Not to say pullbacks are without their issues, but you can at least minimize your risk by not buying at the top.
  • Like any other trade signal, you will need to exit your position without reservation.
  • Conversely, when the upper and lower Bollinger bands tighten, an impulsive move is likely right around the corner.
  • Notice how leading up to the morning gap down the bands were extremely tight.

The breakout is not a trading signal and many investors mistake that when the price hits or exceeds one of the bands as a signal to buy or sell. Breakouts provide no clue as to the direction and extent of future price movement. This example also provides further supporting evidence with the long wick candle formation, indicating a rejection of the new low by bulls. As mentioned previously, the Bollinger Bandwidth indicator does not specify entry/exit levels so other tools need to be used in conjunction. Fibonacci level s are often used to determine theses entry/exit levels as well as price action trend lines to establish support and resistance points.

Signal: Walking the Bands

This makes sense because larger price movements can be expected over longer timeframes. Chart 4 shows Barrick Gold (ABX) consolidating throughout 2006 and into 2007. As the consolidation narrowed and a triangle formed, Bollinger Bands contracted and BandWidth dipped below 10 in January 2007. Notice how BandWidth remained at low levels as the consolidation extended. BandWidth also rose as prices moved sharply in one direction and Bollinger Bands widened. Bollinger bands help determine whether prices are high or low on a relative basis.

The index is not one of the more popular indicators, but that does not mean it lacks accuracy. Trading in the financial markets can be a risky endeavor with just as much potential for reward as gain. Basic Options contracts are no exception to this rule and carry significant risks. If you notice the volatility easing the initial push could be enough for the security to climb the wall of worry. You can jump onboard the trend with a close stop below the most recent low.

If you are thinking about trading with the Bollinger bandwidth indicator, you can do so within Tradingsim. You can practice placing trades and identify which strategy works bollinger bands bandwidth best with your trading style. The Bollinger bandwidth provides a visual of price consolidation (low bandwidth values) and periods of volatility (high bandwidth values).


When the bands are unusually far apart, that is often a sign that the current trend may be ending. When the distance between the two bands has narrowed too far, that is often a sign that a market may be about to initiate a new trend. Upper resistance and lower support lines are first drawn and then extrapolated to form channels within which the trader expects prices to be contained. As long as prices do not move out of this channel, the trader can be reasonably confident that prices are moving as expected. Technical analysis is a trading strategy that analyzes statistical trends to identify trading opportunities. Looking at the increase in volatility or higher Bollinger Bandwidth value on the USD/JPY daily chart, it shows USD/JPY reaching new lows outlined by the square boxes.

Bollinger Bandwidth Does Not Forecast Market Direction

One of the most well-known theories in regards to Bollinger Bands is that volatility typically fluctuates between periods of expansion (Bands Widening) and contraction (Bands Narrowing). With this in mind, the major trading signal generated by Bollinger Bands Width is known as The Squeeze. Thus, it is important to use BBW smartly in tandem with a directional indicator like the Relative Strength Index to ensure that you enter and exit trades with more confidence. The Bollinger Bands Width is an extension of the Bollinger Bands Indicator, both of which are useful technical indicators to identify The Squeeze and its resultant volatility. A Simple Moving Average (SMA) is used to plot the movement of the middle band, which is the price of a stock, commodity, or currency over 20 periods.

Bollinger Bands

This indicator created to identify the strong Support and Resistance levels based on the Bollinger Bands. When two different time frame Bollinger Bands are travelling together then its a strong Support or Resistance Levels. I have added 5 Min, 15 Min, 30 Min, 1 Hr and 1 Day time frame Bollinger Bands in one Chart. Bollinger Band is simply a representation of the rolling average of price and its standard deviation around the average (called the “basis”). There is a tendency for bands to alternate between expansion and contraction.

For the lower band, subtract the standard deviation from the moving average. Using the bands to indicate overbought/oversold conditions depends on the concept of mean reversion of the price. Mean reversion assumes that if the price varies considerably from the mean or average, it eventually reverts to its long-term average levels. Mean reversion trading attempts to capitalize on a security’s extreme price changes, assuming it will regress to its previous state.

That’s why the Bollinger Bands ecosystem is in place – to benefit from “The Squeeze”, a widely accepted phenomenon that occurs after a period of historically low volatility.

The Bollinger Band Width makes it easier to visually identify new highs and lows. It is defined by alternating phases of volatility compression and expansion. In this article, we’ll focus on an instrument derived from Bollinger Bands called the Bollinger Band Width.

A trader can visually identify a squeeze when the upper and lower bands get closer together, constricting the moving average. A squeeze is a sign of decreased volatility and is considered by investors as a possible sign of future increased volatility and potential trading opportunities. Conversely, the further away the bands move from each other, the more likely the chance of a decline in volatility and the more significant the possibility of exiting a trade.

Bollinger Bands can be used in pattern recognition to define/clarify pure price patterns such as “M” tops and “W” bottoms, momentum shifts, etc. If more than one indicator is used the indicators should not be directly related to one another. For example, a momentum indicator might complement a volume indicator successfully, but two momentum indicators aren’t better than one.

It gained its name because it was originally used to analyze… These are but a few of the great methods for trading with bands.
