What Are the Bollinger Bands?
John Bollinger was the creator of the Bollinger Bands. In the 1980s, he invented this method to understand the volatility of any financial instrument or commodity. Moreover, financial traders employ these charts as a methodical tool to tell trading judgments, control automated trading systems, and as an element of technical analysis. Furthermore, Bollinger Bands show a graphical band (the wrap maximum and minimum of moving averages, similar to Keltner or Donchian channels), and volatility (exposed by the beam of the cover) in one two-dimensional chart.
How do Bollinger Bands work?
Two inputs parameters chosen to separate by the user rule, to see how the chart reduces the known historical price data. It also allows the user to vary the reply of the chart, to the magnitude and frequency of the price changes. With, Bollinger Bands uses a statistical calculation known as standard deviation. To establish where a band of likely support or resistance level might lie. This is an earmarked utilization of a broader idea knew as a volatility channel.
A volatility channel plots lines above and below a central measure of price. According to volatility or non-volatility of a market, these lines also known as envelops or bands, widen or contract. Bollinger Bands calculate market volatility and provide lots of useful knowledge, like –
- Trend continuation or reversal
- Periods of upcoming great volatility breakouts
- Periods of markets consolidation
- Possible market tops or bottoms, and possible price target
Bollinger Bands contains three bands. It rotates around a centred simple moving average (SMA). It has the default value of 20, of which 85% of the time. The price held within the following boundaries:
- Upper Band – SMA (minus two standard deviations)
- Lower Band – SMA (plus two standard deviations )
Illustration of Bollinger Band
Bollinger Bands most basic concept is that the channels illustrate a measure of high and low. Let’s know the three key points of Bollinger Bands:
- The upper band shows a level that is statistically high or overvalues
- The lower band shows a level that is statistically low or undervalues
- The Bollinger Bandwidth relations to the volatility of the market
That’s why standard deviation increase as the price ranges broaden and fall in small trading ranges.
- Bollinger Bands widen when the market volatility increases.
- Bollinger Bands narrow when the market volatility decreases.
Trading Strategies of Bollinger Bands

To buy trade, you have to look for the price come to the middle band and bounced higher. After that, if the price breaks above the upper band resistance and closes above it, then enter a buy trade on the next candle. You also have to see that the Stochastic Oscillator and MACD lines are moving upward or cross each other upside. Your stop loss should be below the bullish close candle, which broke the upper band and take a profit level according to the 1:2 ratio.

The first bottom of this type of structure supervises volume and pullback that closes outer of the lower Bollinger Band. Moreover, these types of structures called the “automatic rally”. The price tries to retest the recent lows that have been set to challenge the force of the buying pressure that comes in the bottom after rally starts.
Many traders look for these types of retest candle to strike inside the lower band. It indicates that the hand is changing from the sellers to buyers. Besides, you will see the volume drop off dramatically.

This type of squeezing action of the Bollinger Bands indicator can be a result of an upcoming big move. Besides that, you can also use an additional indicator such as volume expanding or the accumulation distribution. These other indicators can add some confluence to this strategy.
