Bollinger Bands Defined
Bollinger Bands are a technical analysis tool created by John Bollinger that can be used to measure the volatility of a financial asset. Although there are different types of Bollinger Bands, they all consist of three lines: a simple moving average (SMA) line in the middle, and an upper and lower band plotted two standard deviations away from the SMA.
The SMA represents the average price of an asset over a set time period, while the upper and lower bands represent its expected range of price fluctuations. When prices move outside this range, it is considered to be either oversold or overbought. See below for an example of how Bollinger Bands are presented on a Forex technical chart:
There are different types of Bollinger Bands depending on how they are calculated - some use exponential moving averages instead of SMAs, for example. The choice will depend on personal preference and trading strategy.
Traders use Bollinger Bands to help identify trends in price movements or potential breakouts from established ranges. By analysing these patterns, traders can make informed decisions about when to enter or exit trades.
The Three Different Types Of Bollinger Bands
There are three types of Bollinger Bands: the Simple Moving Average (SMA), the Exponential Moving Average (EMA), and the Keltner Channel.
Simple Moving Average
The Simple Moving Average calculation uses the most recent data i.e., if a 21-time period is used as the basis for the calculation, it is the last 21-time frames that are used. When a trading day closes, the oldest time period is dropped from the calculation and the newest included. The upper and lower bands are then drawn above and below this line at a distance of two standard deviations from the moving average.

Exponential Moving Average
The EMA is similar to the SMA but is adjusted to give more weight to the most recent prices, as they are a better indication of current market sentiment. The advantage of the weighted average is that the EMA reacts quicker to changes in market sentiment. This means that it reacts faster to changes in market conditions than its counterpart. The upper and lower bands for EMA also use two standard deviations from this line as their boundaries.

Keltner Channer
The Keltner Channel uses an exponential moving average (EMA) as its centreline, which is then surrounded by two lines that represent an average true range multiplier away from said centreline. Unlike traditional Bollinger Bands, these channels aren’t based on volatility alone but instead consider both volatility and trading ranges.
Each type of Bollinger Band has its own strengths and weaknesses, so traders must choose which one suits their strategy best depending on their style of trading.

How To Read The Bands
Reading Bollinger Bands can be a bit tricky, but with some practice, it becomes easier to understand. The bands consist of three lines: the upper band, the lower band and the middle band which is a simple moving average line.
The upper and lower bands are calculated by adding or subtracting two standard deviations from the middle line respectively. When prices move close to the upper band, it suggests that an asset may be overbought while when they approach the lower one, it indicates an oversold market.
Bollinger Bands can also provide valuable information about volatility in markets. When there’s high volatility, you will notice wider gaps between each of these bands indicating more significant price swings over time.
Traders often use these signals as entry or exit points for their trades since prices usually return to their mean after hitting either of those bands. However, it's essential not to rely solely on Bollinger Bands signals but rather use them alongside other technical indicators such as trendlines and support/resistance levels.
Understanding how to read Bollinger Bands is vital for any trader looking to improve their trading strategies. It helps identify potential buying opportunities in oversold markets and selling opportunities in overbought ones while providing insights into market volatility trends.
Bollinger Band Strategies
Bollinger Bands can be used as part of various trading strategies to help identify entry and exit points.
Bollinger Squeeze
One strategy is the Bollinger Band squeeze. This occurs when the bands narrow, indicating low volatility, which could signal an upcoming breakout. Traders may then enter a long position when prices break above the upper band or a short position if prices break below the lower band.

Overbought v Oversold
Another strategy is using Bollinger Bands in conjunction with other indicators such as Relative Strength Index (RSI). When RSI reaches overbought or oversold levels and prices touch one of the bands, it could indicate a trend reversal.

Traders can also use Bollinger Bands for mean reversion trades by buying when prices fall below the lower band and selling when they rise above the upper band.
Remember that no single trading strategy is fool-proof, so it's essential to back-test your ideas and always practice proper risk management techniques.
Summary
To sum it up, Bollinger Bands are a popular technical analysis tool used by traders to identify potential market trends and volatility. They help in determining the upper and lower price bands of an asset based on its moving average.
In this article, we have discussed the three different types of Bollinger Bands including Simple Moving Average (SMA), Exponential Moving Average (EMA), and Double Bollinger Bands. We have also explained how to read these bands and provided some useful strategies for trading with them.
It's important to remember that while Bollinger Bands can be a powerful tool in your trading arsenal, they should not be relied upon solely for making investment decisions. As with any technical analysis tool, it is always best to use a combination of indicators and perform thorough research before making any trades.
