Bollinger Bands

Bollinger Band is a technical market analysis tool developed by John Bollinger in 1980s. It consists of three different lines; one above the price line, one below it, and one in the middle of both the lines. The middle line is the simple or exponential moving average of the commodity. The other two lines are the standard deviations of the commodity’s price, one negative and one positive.

These lines can also be customized, but it is best to keep them in default. Standard deviation lines calculate the volatility of the asset and show how the price is moving.

What is the use of Bollinger Bands?

Bollinger Bands measure the noise of a price chart, i.e. quiet or loud. In other words, it measures the volatility of the price. When the market is less volatile, the upper and lower line comes closer. And, when the market is too unstable, the lines move apart.

Initially, Bollinger Bands were known as trading bands but, in 2011, John took the copyrights and named it Bollinger Bands.

A price chart with Bollinger Bands looks like the below figure.

  • If bands start coming closer, then it might be a sign of price change.
