Introduction :

We divide technical analysis indicators in the cryptocurrency market into two parts, which are the driving indicators that follow the price movement, which are indicators that are compatible with the strong trends of the financial markets. Indicators are the moving average indicator, in addition to the section of oscillating indicators, which are technical analysis indicators that depend on volatility to predict the upcoming price movement with high accuracy, such as the Relative Strength Index (RSI), in addition to the Bollinger Bands indicator.

Through this lesson, we will work to explain the trading indicator Bollinger Bands in the cryptocurrency market, where we will explain its components and method of calculation, in addition to that we will present how to trade using it, in order to suit all traders, whether they are professionals or beginners. Good reading !!

Bollinger Bands: What is it and how does it work?

Developed by the famous John Bollinger, Bollinger Bands have become one of the essential tools of technical analysis. Bollinger Bands allow a moving average of a security to be wrapped between two bands serving as both support, resistance, and/or trend indicator. They can thus be likened to a channel. Bollinger Bands use a moving average price as well as the volatility of that same moving average.

Simple to understand and to construct, Bollinger bands quickly established themselves as one of the most interesting chartist analysis tools to study. Of course, they do not in any way predict the future with accuracy, but they do allow us to estimate its possibilities.

  • Formula or method of calculating the Bollinger Bands indicator

Before building the envelope, it is necessary to calculate the moving average of the security to be studied. Achieving a moving average is relatively straightforward.

Moving Average = Sum of prices over x days/number of days

John Bollinger advocates the use of a 20-day moving average, although it is possible to use other moving averages (10-50 days).

Once the moving average of the security is calculated, Bollinger Bands can be achieved. These use the volatility (standard deviation) of the moving average. The higher the volatility of the stock, the further the bands will move apart and thus indicate a clear trend in the stock. There are two bands, one upper and one lower.

  • The upper band is calculated by adding to the moving average, 2 standard deviations.
  • The lower band is calculated by subtracting from the moving average, 2 standard deviations.

Note that we use 2 standard deviations because this is a 20-day moving average. A 10-day moving average will require 1.5 standard deviations, and a 50-day moving average will require 2.5 standard deviations.

Once the moving average and the two bands are calculated, it is then very easy to draw them.

  • Representation of the Bollinger Bands indicator

On the Ethereum / USD chart below, we have added the Bollinger Bands.

Figure1: Components of the Bollinger Bands Indicator

Bollinger bands are formed by 3 lines. A central line (in orange) and two lines, lower and upper. The centerline is a simple moving average.

You can see from the chart that the price action is oscillating between the lower and upper bands and that the majority of candles are contained in these bands.

First, Bollinger bands allow you to clearly see the ups and downs of the market. This is because the peaks touch the upper line of the indicator, and the troughs touch its lower line. However, you will be able to discover less obvious uses which will allow you to determine the volatility and the strength of the trend.

Interpretation of the Bollinger Bands Indicator in cypto trading :

  • Measurement of volatility and Breakout :

Bollinger bands are an indicator of volatility. They can spot the increase or decrease in the volatility of any asset, including cryptocurrency currency pairs. When the bands widen, it means that volatility increases. Conversely, as they shrink, volatility decreases.

The Tron chart below illustrates the behavior of Bollinger Bands vis-à-vis volatility. In March, the bands were quite thin, a sign that volatility is low in the market. At the beginning of April, the downward breakout followed by the drop in the price of Tron increases market volatility. The bands widen accordingly.

1.PNG

Figure2: Determination of volatility for the TRX / USD pair

When the bands narrow to the point of becoming very thin, it signals low volatility in the market. It also heralds a potentially violent breakout. This breakout is often the result of news in the markets.

Indeed, in traditional markets, it is not uncommon for investors to reduce the size of their positions or not trade, pending major economic news. This decrease in trading volume significantly reduces market volatility.

And when the breakout comes, the price comes completely out of the Bollinger Bands which then start to widen again.

Therefore, when the Bollinger bands are very thin, traders are on the lookout for breakout trading opportunities.

2.PNG

Figure3: Identification of a Breakout

On the Ripple chart above, you can see this phenomenon. The bands got very thin just before the breakout, which was followed by an uptrend.

-Trend reversal :

Bollinger bands can help you spot market reversals or trend changes. This is because when volatility increases dramatically, the price comes out of the bars after the breakout. If more than one candlestick is formed on the outside of the bands, the first candle returning to the bars indicates a possible reversal in the trend.

4.PNG

Figure4: Bollinger Band Breakout

The chart above shows that Cardano's price completely breaks through the bands and forms several candles outside of it. The return of price action in the bars indicates a trend reversal. Note, however, that this signal conflicts with the market's direction. Therefore, one must negotiate with caution.

Overbought and Oversold

The Bollinger Bands indicator is also used to determine the overbought and oversold areas in the market. But it is important to note that this operates in a relatively calm and diversified market.

  • Overbought

An asset is considered overbought when it is trading at sufficiently high prices. This can be determined using the Bollinger Bands. When price touches the upper line while bands have a relatively normal spread, the market is considered to be overbought. So traders can start selling or making their profits (for buyers). Price action tends to pull back to the central moving average or even the bottom line of the slides.

  • Oversold

Conversely, an asset is considered oversold when it is trading at relatively low prices. Analysts can use ranges to identify selling areas on their chart. In fact, when price action touches the lower line of the range, it is considered that the market is oversold. In this case, the sellers can start to reduce the position size or take their profit. On the other hand, other traders see this as a buy signal.

Price retracement of the upper and lower lines can give powerful trading signals when combined with candlestick patterns such as hammers or spinning tops.

Figure5: The Bollinger Bands identify overbought and oversold areas

- Determination of the market trend

Bollinger bands are a quick way to see the market trend, like moving averages. The bands are more visual than a simple moving average line. In addition, the moving average can generate false reversal signals, when the price moves below or above the indicator.

Bollinger bands on the other hand envelop the price and give a better overview of the underlying market trend. Determining this trend is a snap! When the bands go up, the trend is up, and when they go down, the trend is down.

6.PNG

Figure6: Using BB to identify the market trend

Bollinger Bands highlight the bullish and bearish trends on the chart above. At first, they move upwards, then after the Ethereum breakout downwards, the bands have reversed.

In a sustained trend, the central moving average of the Bollinger bands can act as dynamic support and resistance. In an uptrend, the rebound of the price on this central line offers traders opportunities to buy in the direction of the trend.

In a downtrend, bounces off the 20 moving average provide opportunities to sell in the direction of the trend.

line.png

Support and Resistance

Bollinger bands can be used in conjunction with other analytical tools such as fixed supports and resistances defined by price action. Indeed, the rebound of the ends of the bands can coincide with a support or a resistance already defined.

7.PNG

Figure7: BB with Resistance and Support

Going back to our 1-day chart on the Bitcoin / USDT pair, we notice that the first two rebounds on the upper line indeed coincide with a resistance that was support before the BTC / USDT price break.

line.png

How to set up Bollinger Bands?

The default parameters generally programmed in the trading platform, the number of periods over which the central moving average is calculated is 20 while the standard deviation which makes it possible to define the values of the upper and lower bands is multiplied by 2.

It turns out that with this type of setting, statistics show that in most cases prices should stay within these bands.

8.PNG
Figure8: Setting BB inputs using TradingView

1- Lenght: By default, it is 20 which means the last 20 candles.
2- Source: Close: It means that we use the closing price of the candle to calculate the moving average
3- StdDev: By default, it is 2 which means twice the standard deviation, but you could put 50 in periods and 2.5 in standard deviation, which would mean 2 and a half times the standard deviation for the spacing of the bands.
4- Offset: By default, it is 0 which means the number of candles ahead of the graph, it is not very useful.

Advantages and disadvantages of the Bollinge bands indicator

Pros:

  • Identifies the phases of lateralization (horizontal channels)
  • Identifies the start of a new trend with an increase in volatility
  • Allows you to simply follow the volatility of a security

Cons:

  • Only one indicator remains
  • Does not identify the causes of the change in volatility

line.png

Conclusion :

Bollinger bands are similar to moving average envelopes but are plotted at standard deviation levels above and below a moving average.

Bollinger bands are subject to several interpretations in terms of their possibilities and the way traders use them.

For example, they can be used as a "mean reversion" indicator to show if the price might be overvalued one way or the other.

In another case, they could be interpreted as an indicator of trend following and end of the trend when prices move outside the envelopes and they close below or above thus indicating the "break" of the tendance.

Bollinger bands can also clearly represent current market volatility, with contracted Bollinger bands indicating low volatility (with the possibility of a breakout) and wide bands indicating high volatility (with the possibility of a period followed by a breakout). 'low volatility).

Bollinger bands are not designed to be used on their own.

How they are interpreted on a chart depends a lot on the trader.

Hello, dear professor @kouba01,
Thanks for your lesson. It's indeed, a great one.
But here is what I do not understand

How to use Bollinger bands with a trending market

As in one of the comments you say that as you elaborate it as the best parameters to use to get the most accurate signals when trading? but as in this Bollinger bands, there are two parameters which are period and standard deviation. But I think you are talking about periods like in which period we can get the most accurate signals in trading, right? Like in 10 days, 20 days, or 50 days?

Thanks you

As the number of periods involved changes, you need to change the number of standard deviations used. You have to tell us how we do it and why? Is it according to trading strategy or randomly?
