How Bollinger Bands indicator is constructed?
Bollinger Bands is an indicator that sets the range of asset price movement. It is built on the basis of three moving averages one in the middle and two others located the same distance from the first one. Range width is calculated by the mathematical formula of standard deviation.

Its coefficient may be set in the indicator settings. The higher the coefficient the wider the range and the more infrequently the chart reaches borders.

Period is a number of candlesticks used in the calculation of indicator parameters. Increasing period smooth the corridor but does not guarantee an increase in indicator performance accuracy.

How do Bollinger Bands work?
When the price approaches or touches one of the lines, the probability of its movement shifts to the opposite direction.

The breakdown of one of the lines signals probable trend movement towards the breakdown. This type of behaviour can be used in a Bollinger Band breakout strategy.

The higher the volatility on the market the higher the corridor.

Long term location of the indicator is in a narrow range. Usually preceding upheaval in the market.

How to use Bollinger Bands
With the principles of the Bollinger Bands indicator mentioned earlier, it is quite easy to imagine what specific signals it can generate for trading. Here we could distinguish 2 basic types of signals:
Bounces from the upper and lower bands. Seeing that the price respects these lines you can sell on the upper and buy on the lower band.
Breakouts from the upper and lower bounds. If the market dynamically crosses the upper band upwards it may be a buy signal. Conversely, if the price dynamically breaks through the lower band it may be used as a sell signal.
Additionally, it is worth observing the width of the band in order to know what is the current situation on a given asset. If the band is wide, we are usually dealing with a strong trend and high volatility. At such moments it is worth using additional tools to join the trend. If the band is narrow, it is usually due to a consolidation of the market. In such a scenario I personally prefer to wait for a directional breakout and only then look for a signal to enter a position.
The Bollinger Bands indicator is best used in combination with other indicators. By the time a strong trend takes place. This indicator alone becomes ineffective.

4 Useful Insights from the Indicator
Bollinger Bands are one of the most popular technical analysis indicators used by traders worldwide. They were created by John Bollinger in the 1980s and are widely used to identify potential price trends, volatility, and momentum. In this article, we will dive into the details of how Bollinger Bands work and provide you with four useful insights to help you become a better trader.
Insight #1: Understanding the Basics of Bollinger Bands
Bollinger Bands consist of three lines, which are plotted using a moving average and two standard deviations. The middle line is the simple moving average, while the upper and lower bands represent the standard deviations. The distance between the upper and lower bands will change according to the level of volatility in the market. When the market is highly volatile, the distance between the bands will increase, indicating a potential price movement.
Traders use Bollinger Bands to identify the support and resistance levels. When the price moves towards the upper band, it indicates a potentially overbought market, while a move towards the lower band indicates an oversold market. However, it's important to note that Bollinger Bands are not always accurate and should be used in combination with other technical indicators.
Insight #2: Identifying Breakouts and Reversals
Bollinger Bands can also be used to identify potential breakouts and reversals in the market. When the price moves beyond the upper or lower band, it's considered a breakout. A breakout indicates that the price has broken through a significant level of support or resistance, which could lead to a significant price movement in that direction.
On the other hand, a reversal occurs when the price moves from an overbought or oversold condition and moves back towards the moving average. This could indicate that the current trend is losing momentum, and a reversal may be imminent.
Insight #3: Combining Bollinger Bands with Other Indicators
Bollinger Bands work best when used in combination with other technical indicators. One popular indicator to combine with Bollinger Bands is the Relative Strength Index (RSI). The RSI measures the strength of a security's price action and is often used to identify overbought and oversold conditions.
When the RSI is overbought and the price is at the upper band, it could indicate a potential reversal. Conversely, when the RSI is oversold, and the price is at the lower band, it could indicate a potential reversal to the upside.
Insight #4: Using Bollinger Bands to Manage Risk
Bollinger Bands can also be used to manage risk when trading. Traders can use the bands to set stop-loss orders or trailing stops. When the price moves outside the upper or lower bands, it could indicate that the trend is reversing, and traders may want to exit their position. By setting a stop-loss order just outside the bands, traders can limit their potential losses and protect their capital.
Additionally, traders can use Bollinger Bands to set profit targets. When the price reaches the upper band, it could indicate that the trend is becoming overextended, and traders may want to take profits. By setting a profit target just below the upper band, traders can lock in their profits and exit the trade.
