Bollinger Bands (BB) is a technical indicator used to measure price volatility in financial markets. It was developed by John Bollinger in 1983. It is now widely used by investors and analysts to assess risk and profit potential.
The BB indicator consists of three lines:
- Moving Average (MA): Usually a 20-day simple moving average (SMA).
- Upper Bollinger band (BB upper band): Located at a distance of K times the standard deviation of the price from the MA line.
- Lower Bollinger band (BB lower band): Located at a distance of -K times the standard deviation of the price from the MA line.
Value of K:
- The default K value is usually 2. However, it can be changed depending on the investor’s purpose of use and trading strategy.
- A higher K value will produce wider Bollinger bands. It indicates higher volatility, and vice versa.

Bollinger Bands Indicator Structure
The BB indicator is a popular technical analysis indicator. It is made up of three main lines:
Moving Average in Crypto Indicators
Concept:
- Moving average (MA) is a popular technical analysis indicator used to calculate the average price of a security or cryptocurrency over a given period.
- MA helps investors smooth price data, eliminate market noise and easily identify market trends.
Below are the current types of MA lines:
- Simple MA (SMA): Calculates the average of the closing prices of the last n bars.
- Exponential MA (EMA): Assigns higher weight to more recent prices. It helps the MA react faster to price changes.
- Considered MA (WMA): Assigns weights to prices based on certain criteria, such as trading volume.
Upper Band and Lower Band Indicator
Concept
- These are two parallel lines drawn at a distance equal to K times the standard deviation of the price from the moving average (MA).
- K is usually 2 but can vary depending on the intended use. Or the investor’s trading strategy.
Meaning of upper and lower borders
- Upper boundary: Shows the highest price that the price can reach in a given period with probability K%.
- Lower boundary: Shows the lowest price that the price can reach in a given period with probability K%.
