Bollinger Bands

Introduction to Bollinger Bands Indicator

Bollinger Bands is a trading band focused on the price volatility of a simple moving average (SMA). Variance is calculated by measuring the normal statistical deviation from the same volume of data. John Bollinger proposes a 20-day average for measuring a Bollinger band. This is a plain, non-volatile, one-day average of a single currency pair price.
The Bollinger Bands determines normalized prices in comparison with an average of 20 days. This is the number of days his research has shown to be the most accurate method of detecting deviations in US equities. It has become the standard for currency pairs as well.  Bollinger Bands are a statistical trading instrument,  used by financial traders. In the context of automated trading systems, as a quantitative tool for assessing trade decisions. A good thing about Bollinger Bands is that they can be seen in several respects, as a test of uncertainty and as a currency pair demand tracker.

The Purpose of Bollinger Bands

As a technical predictor, it may be a valuable method for a trader to achieve an edge in forecasting possible market fluctuations. Bollinger Band Indicator also acts as a complex measure of support resistance and can also be used to suggest patterns
Bollinger Bands measure market fluctuations. It forms a band that extends or shrinks as volatility increases or decreases.

How to Set Up Bollinger Bands in Your Trade View

Bollinger Bands are a kind of umbrella that can be interpreted by adhering to size, price to earnings ratio) as a metric on BigCharts.  A loop of variance plots lines above and under a central market index. Such lines are referred to as envelopes or bands, and they extend or contract depending on how competitive or volatile the market is
Here is how to set up Bollinger Bands in your view of your trading software.
  1. Drop Bollinger Bands in the map 
  2. Head to ‘settings’ and pick two standard deviations and a basic moving average (SMA) of 20-periods.
  3. Attach another collection of Bollinger Bands of a new color 
  4. Go to ‘Settings’ again and pick one standard deviation and a 20-period SMA

How to Use Bollinger Bands in Swing Trading

Bollinger Bands may be used as the basis for a large variety of swing trades such as short- and long-term trades.
In a swing trading system, the trader will use Bollinger’s battered b-bands in the same way as a long-term pattern path. This will allow the trader to see a start and end of the most volatile period and a low volatility phase. A trader using the band from Bollinger would be able to detect the first hint of a downturn in the pattern. The trader can opt to use the classic Bollinger tape until the price has dropped off the trend axis.

Knowing Bollinger Bands zones

A1 is the lowest Bollinger Band line which is two standard deviations apart from X, which is the 20-period SMA 

B1 is the bottom Bollinger Band line which is the 20-period SMA 

X is the standard deviation. It acts as both the middle of the Double Bollinger Bands (A1B1 and A2B2) 

B2 is the lower BB line and is one standard deviation away from the 20-period SMA 

A2 is the lower BB line, which is two standard deviations away from the 20-period SMA.

The zone between A1 and B1 is the Buy Zone, the first Neutral Zone is between B1 and X, the second Neutral Zone is between X and B2, the Sale Zone is between B2 and A2.

How Do You Spot Patterns With Bollinger Band?

The Bollinger Bands is an adaptive trading band which tracks volatility changes. It also provides a measure of price volatility and market volatility.
Bollinger Bands’ standard formula sets the centerline as a simple moving average. The upper and lower bands are calculated based on the mean of the two lateral bands, which is called the standard deviation
The outer Bollinger Bands are based on market fluctuations. So, it means that as prices fluctuate against a trend, the banding extends. But as inflation increases, Bollinger Bands grow and the bands shorten and expect a downward tendency as rates get lower.
The Bollinger band remains a good indicator of short-term trading. But many traders still use the band to assess overbought and oversold prices.

How Accurate are Bollinger Bands?

One of the most reliable pattern markers used by traders is the Bollinger band. It can be much more consistent when paired with other indicators.
Bollinger Bands are a technological research device that shows the price impact of security. This is achieved by illustrating its stability over a period of time by band expansion and contraction. Bollinger Bands may be a reasonable predictor of whether a stock is expected to rise or decrease in volatility in the future.

How Much Predictive Power have Bollinger Bands Got?

The main moving averages for the S & P 500 and Dow Jones Industrial Average are the upper and lower bands of Bollinger. They form an envelope around the closing price and contain the bulk of price action. Since Bollinger Bands quantify volatility, they may help confirm the intensity of trends. The centreline is formed with an exponential moving average to create a Bollinger band on a share price map, and the band contract is contracted
Looking at the Bollinger band’s 20-day average on a share price map, you can see that two trading bands were added. Bollinger Bands are a method for dividend investors to grasp short-term price fluctuations when it’s time to buy a stock.

What Indicator Combines Well With Bollinger Band?

Combining Bollinger Bands with other metrics will help traders make smarter decisions. Bollinger Bands provides traders with a clearer view of metrics to detect patterns and opportunities in developing markets. The Bollinger Band Strategy is a continuous strategy that uses a 20-period moving average band for the direction of the trend as well
Traders can use Bollinger Bands to help trades and setups in tandem with Moving Average Convergence Divergence (MACD). Bollinger Bands can be used as a key to later validation transactions. It enables traders to take into account the cyclical nature of markets. Whereas MACD is an efficient pattern, follow-up and impulse indicator. Combined with Fibonacci quotas, Bollinger Bands also have a strong base for trading strategies. Bollinger Bands display the upper- and lower-range price pattern, as well as the direction of market growth.

What can Bollinger Bands Identify?

Bollinger Bands are one of the technological analytic tools for conducting technical research on the market. They are used by traders to quantify currency pair price fluctuations and calculate volatility. The bands indicate the demand pattern in the upper and lower scales, as well as the market growth path. Bollinger Bands explain the price effect of an asset by reflecting its volatility within a band over a span of time as an expansion or contraction
Bollinger Bands calculate uncertainty in the market and offer other valuable details such as; 1. Continuing or changing pattern 
  1. Company Consolidation Periods 
  2. Periods with large volatility breakouts come up 
  3. Possible bottoms or market peaks 


John Bollinger, the developer of Bollinger Bands suggests a setting of 9-12.

Bollinger Bands help you decide whether the rates are high or low. They are used in pairs, higher and lower bands, often with a rolling average. Additionally, the pair of bands are not meant to be used. Use the pair to confirm other indicators.
By charting the ratio of higher closes, investors may determine whether a stock is overbought or oversold. It is an oscillator of momentum that determines the way a stock is moving, and the speed of travel.

Short-term moving averages are preferred by traders who want to trade with the current dynamic market. The 10 EMA and 20Ma are the most common exponential moving averages for the short term. These moving averages react most quickly to price moves.

The best indicators are 

Stochastic oscillator 

Moving Average (MA) 

Exponential Moving Average (EMA)
