Bollinger Bands respond to market conditions by calculating price volatility. 

That’s what makes them so useful for crypto traders: between the two bands they can find almost all the price data they need.

What’s a Bollinger Band?

This little device basically tells us if the market is quiet or if the market is LOUD!

The bands contract when the market is quiet and the bands grow when the market is LOUD.

Remember on the chart below that the bands are close together when the price is quiet. The bands break apart when the price moves up.

Bollinger Bands consists of one center line and two above and below value channels (bands). 

The middle line is an exponential moving average; the price channels are the standard stock deviations being investigated. 

The bands may extend and contract as a problem’s price action is unstable (expansion) or bound into a tight pattern of crypto trading (contraction).

Who invented Bollinger Bands?

John Bollinger, an American financial analyst, writer and consultant to the field of technical analysis, invented Bollinger Bands, which was used by novices and experts.

In the early 1980s, he began developing Bollinger Bands. 

He was interested in trading options back then, and most of his research was about volatility.

Bollinger took the Keltner Channel as the underlying basis in the creation of his theory. 

His concept was to add standard deviation in volatility to allow more efficient trading groups.

He charted the closing price with the bands on both sides on a 20-day moving average, reflecting doubled standard deviations of the moving average.

On the Financial News Network in 1983, Bollinger first introduced the concept to the world. 

His book “Bollinger on Bollinger Bands,” which was published in 2001, has been translated into 11 languages. In the trading environment, he also coined the term ‘ rational analysis’ as a tool for evaluating markets with an emphasis on related fundamental and technical factors.

Why Bollinger Bands useful in Crypto Trading? 

Bollinger Bands offer a lot of advantages to crypto traders. 

The Bollinger Bands graph can be very useful for determining price trends in markets that appear to be rather unpredictable, reading the trend power, timing entries during range markets, and detecting potential market tops in a flexible, adaptive way.

Bollinger Bands are often used in combination with other analytical tools, so it can provide an objective view of the markets and serve as a key decision area for different trading strategies.

How To Use Bollinger Bands When Trading Crypto? 

Identify the upper and lower bands as price targets when using Bollinger Bands. 

The upper band comes to reflect the higher price target when the value deflects the lower band and crosses above the 20-day average (the middle line). 

Prices usually fluctuate between the upper band and the moving average of 20 days in a fast uptrend. 

A crossing below the 20-day moving average when this occurs

Bollinger bands are used in many ways. 

But it’s important to note that this doesn’t automatically mean sale when the price hits the upper band. Likewise, it doesn’t necessarily mean purchasing if the price hits the lower band. 

Actually, take it from John Bollinger himself who said, “There is literally nothing about a band’s label that is a signal in and of itself.”

During a powerful down-or up-trend, prices will “walk the show.” 

This implies that the lower or upper band is repeatedly touching or breaking through a value. 

That’s why you may not want to take action when either band is affected by the cost, and may rather wait to try a “double bottom,” a “classic M top,” or a “three pushes up” formation.

Which Signals To Look For

The bands typically appear to move in a synchronous fashion during normal market times, but you can use them to see market volatility.

  1. If the gap between the bands is near, it suggests low market volatility.
  2. If there is a large gap between the bands, this shows high market volatility.

Traders find the instrument to be trading within its average when price movements closely follow the middle group.

Bollinger Bands Performance

Bollinger bands are an important source of technical analysis, but they have limitations. 

Bollinger bands are based on the simple moving average of an instrument which uses past data points.

As a consequence, and not predicted, the bands will always respond to price movements. Bollinger Bands are, in other words, reactive, not predictive.

Bollinger bands, too, may be prone to giving false signals. 

For example, when the price of an instrument passes through the trade entry point, a false breakout occurs. 

It signaled a deal, but then pushed in the opposite direction. 

This leads to a loss of trade.

Traders should also recognize that not all approaches will be suited by default settings. 

A greater number of intervals and a higher standard deviation may be favoured by long-term traders. 

Short-term traders may tend to use fewer periods and lower standard deviation.

Because they have drawbacks, in combination with other technical analysis devices, Bollinger Bands are best used. 

Movable averages, stochastic measurements and trend lines can be included.

Features of Bollinger Bands


The condition is called the squeeze when the price bands come closer together. 

These cycles suggest low current volatility and in the near future the potential for high volatility. 

However, while volatility is expected to increase, the predictor does not provide the trader with the details about a particular time. 

During the pinch, traders remain largely inactive.

Combine and conquer

Bollinger bands are good at showing current volatility and sometimes predicting future market fluctuations, but they are not a standard method for trading. 

This measure should be paired with other measures for optimum predictive ability and effectiveness, according to Mr. Bollinger himself.


Approximately 90% of the price action between the price bands takes place. 

The incidents that occur in the remaining 10% of the time are considered breakouts. 

A breakout is an activity that leaves the “standard” price range of price action. 

We should not be used as trading indicators because they do not provide any information about the intensity and course of future trends.

Bollinger Band Limitations

Bollinger bands are a useful indicator, but they have a variety of constraints. 

Bollinger bands are created from a simple average of movement, which is the average price over a number of price bars. 

This means that Bollinger Bands will always respond to price movements, but they will not predict them. 

Bollinger bands are not predictive, they are reactive.

For all traders, default settings won’t work. Effective traders may want a small number of periods or a lower standard deviation, while long-term traders may want a larger number of periods and a larger standard deviation, so there are no indications. 

Through changing the settings, though the pattern based on the guidelines or finding W-Bottoms or M-Tops may be more difficult to gage.

In reality, M-Tops and W-Bottoms may not end up being reversals, but simply consolidations where the price tends to move in the direction of the trend after a false breakout. 

A false breakout is when the price goes through the entry point, initiating a sale, but then moving quickly in the other direction leading to a loss. 

That’s why losses from stops are used.


The indicator for the Bollinger Bands is just one device. It has limitations and will not always generate accurate signals. 

Nonetheless, it can help you stay on the trend side and spot potential reversals. 

To do this, you will need to configure the metrics in order to match them with the above guidelines. 

It may not work well to set the indicator randomly or by definition. 

Place the indicator and check it with paper

The above instructions are not on their own a trading strategy. 

A crypto trading strategy includes entry points, exit points, and risk management that this article has not addressed

Nevertheless, Bollinger Bands can be paired with a market technique, such as the two-hour process of crypto day trading stocks.

This measure may be useful for traders seeking trend reversals when either the Bollinger bands ‘ upper or lower channels are hit. 

The reversals can last from short to longer periods of time and can therefore be used for all forms of traders that may find trading in intraday to trading in place.
