A Brief Summary to Understanding Bollinger Bands

John Bollinger developed Bollinger Bands during 1983. Now, they have become one of the primary tools for traders. These bands indicate three lines on price charts wherein the middle one is simply a moving average.

Setting a distance of the upper and lower band from the middle. Traders usually use a moving average of 20 periods. The bands are two standard deviations apart, showing how much the market is changing.

The Bollinger Bands indicator displays price action and volatility. A great deal can be learned through the width of the band: narrow bands indicating low volatility and wide bands indicating high volatility.

When the bands start to come closer, the squeeze usually indicates that large changes in price are imminent.

Touches to the bands can offer trading opportunities. However, the touching of the bands does not translate to a buy or sell. For example, a double bottom near the middle band may suggest a buy. An M top near the upper band may imply a sell.

Applying Bollinger Bands helps understand the market. The middle band's direction shows the strength of a trend. Upward slope equals uptrend, and downward slope equals downtrend. Knowing this helps with trading.

The Beginnings of Bollinger Bands and Their Creator

Bollinger Bands were developed by John Bollinger in the mid-1980s. He is a Chartered Financial Analyst and a Chartered Market Technician. He wanted a tool that can adjust to the changing volume of the markets.

This idea came through John and realization of the markets' change. Obviously, this made a popular trading tool.

He made the bands flexible to traders. They change with market conditions. This helps traders see price changes and possible market shifts.

The bands have three parts: one middle band and two outer bands. The middle band is a 20-day moving average. The outer bands are based on how far they are from this average using standard deviations.

This setup shows the relationship between price and volatility. The greater the volatility, the wider the bands; otherwise, when it is low, the bandwidth is narrow.

John Bollinger's work changed technical analysis. Bollinger Bands are now an important tool for traders in many markets. The trademark for Bollinger Bands was registered in 2011, showing John's significant impact.

Traders use these bands to see when the markets are overbought or oversold. The work by John Bollinger has greatly affected the trading strategies of today.

How Bollinger Bands Work in Trading

Bollinger Bands help us see the variation in prices during markets. They, in fact, illustrate the highest and lowest prices by tracking the price movements. The bands encompass around 95% of price changes for the estimated 20 days, thus have great significance for traders.

Bollinger Bands: Understanding Highs and Lows

Watching price changes with Bollinger Bands helps find market highs and lows. High prices close to the upper band mean it could be overbought. Low prices close to the lower band suggest it might be oversold. This information helps traders choose when to buy or sell.

Knowing the Bands: High and Low Limits

The upper and lower lines of the Bollinger Bands are of crucial importance in trading. The top line usually indicates resistance to strong upward trends, while the bottom line represents support to strong downward trends. The space between these lines denotes the amount by which the market is changing. This information, along with other indicators, helps make trading strategies better.

Bollinger Bands offer a variety of trading strategies to choose from. Some of the well-known ones include:

  • Mean Reversion: Betting that prices will return to normal. We get on trades close to the upper or lower bands in the hope that a change.

Setting Up Your Bollinger Bands: Key Settings to Consider

We would need to understand the main settings of Bollinger Bands in order for us to do good trading decisions. The basic setup uses a moving average and standard deviations. It usually starts with a 20-day simple moving average and 2 standard deviations. That is quite a strong foundation for our Bollinger Band strategy.

Selecting the Correct Time Frames

The time frame chosen is very important. Bollinger Bands can be used on anything from one-minute to daily charts. The shorter time frames give more signals, which is great for scalping or day trading. Longer time frames are better for swing trading because they give clearer points to enter and exit.

Default Settings and Custom Adjustments

The Bollinger Bands are powerful, but default settings are just so. Scalpers and those who desire very fast market change recognition may want to use a 9 period with 2 standard deviations. Swing traders may choose longer period settings to reduce daily noise. The standard deviation field can be modified as well—for example, changing from 2 to 1.9 or 2.5—fit to our trading.

Scalping1-Minute to 5-Minute2
Day Trading15-Minute to 1-Hour2
