A Beginner’s Guide To Bollinger Bands®

Usually the same period is used for both the middle band and the calculation of standard deviation. By adjusting the settings though it may be more difficult to gauge the trend based on the guidelines or spot W-Bottoms or M-Tops.

The Bollinger Band indicator was invented by renowned trader and financial analyst, John Bollinger in the early 1980’s. They essentially help you identify possible price reversals by determining overbought and oversold levels using standard deviation. During flat markets, the upper and lower Bollinger Bands tend to hover very close to the SMA. Because of this, reading the Bollinger Bands don’t provide too much trend analysis insight during sideways price action.

We know that markets trade erratically on a daily basis even though they are still trading in an uptrend or downtrend. Technicians use moving averages with support What is Bollinger Band? How to Read and Calculate and resistance lines to anticipate the price action of a stock. Envelope channel has evolved into a generic term for technical indicators used to create price channels with lower and upper bands. A trader can visually identify when the price of an asset is consolidating because the upper and lower bands get closer together.

Back in 2011, Crestmont Research conducted a study of the historical relationship between volatility and market performance. For its analysis, Cresmont measured the volatility of the S&P 500 using the average range for each day. That’s when the price of the underlying asset is between the -1 standard deviation lower band and -2 standard deviation lower band . Therefore, there’s a high probability that the price will continue in its bearish fashion. This strategy is the opposite of the Double Bottoms and is meant to identify trend reversals. In this instance, the price registers two high tops close to or sometimes even above the upper Bollinger Band.

In the early 1980s, Bollinger created these bands that now bear his name. His goal was to create a method for making sense of the volatility that’s constantly at hand with stock price movement. A narrowing of the bands suggests that the next move will be a volatile one. Swing traders should watch a stock with narrow bands carefully to identify the breakout from resistance or breakdown from support. This breakout or breakdown can often yield a profitable trade. Bollinger improved on this envelope theory by making it dynamic rather than fixed. He used a 20-period moving average, and then created bands that were based on standard deviations.

Calculating Bollinger Bands®

For traditional Bollinger Bands®, the measure of central tendency is a simple moving average using the most recent 20 days. In other words, the standard deviation is the measurement of volatility, which, in turn, is used to measure the riskiness of an investment.

Third, prices move above the prior high but fail to reach the upper band. The inability of the second reaction high to reach the upper band shows waning momentum, which can foreshadow a trend reversal. Final confirmation comes with a support break or bearish indicator signal. Bollinger Bands consist of a middle band with two outer bands. The middle band is a simple moving average that is usually set at 20 periods. A simple moving average is used because the standard deviation formula also uses a simple moving average. The look-back period for the standard deviation is the same as for the simple moving average.

On the other hand, instances of resistance occur when an upward trend is “condensed” and will likely reverse downward in the near future. This means that about 90-95% of price movements will occur within this range. I would suggest drawing a horizontal line on the 50.00 level in the RSI indicator before starting.

Reading the Bollinger Bands technical indicator is easy, with some practice. By watching for when the bands narrow tightly, it often signals that a large move may be ahead. When volatility drops, it often resumes once a trading range is broken. Bollinger Bands USD to RUB can help forecast these large movements ahead of time, resulting in substantial profit. Bollinger Bands often use the 20-day simple moving average to begin the calculation, then average out the close price for the first 20-days as the initial data set.

How To Use The Bollinger Band Indicator

Typically, each band is positioned two deviations away from the respective positive and negative SMA positions. You can use Bollinger Bands® as part of your stock research to help you determine whether a stock meets your criteria for making a trade. That’s right, you can make more intelligent and knowledge-based trading plans. If a stock continues to close outside the band, this is a continuation signal. In other words, the shares are likely to continue trading in the same direction. Bollinger Bands are named after John Bollinger — a well-known commentator and technical analyst. He noted that trading opportunities often arose when the stock reached one end of the envelope and then began to reverse.

In the 1980s, John Bollinger, a long-time technician of the markets, developed the technique of using a moving average with two trading bands above and below it. A moving average is a technical analysis indicator that helps smooth out price action by filtering out the “noise” from random price fluctuations. Donchian Channels are moving average indicators developed by Richard Donchian. They plot the highest high price and lowest low price of a security over a given time period. Keltner Channels are volatility-based bands that are placed on either side of an asset’s price and can aid in determining the direction of a trend. Bollinger Band® “bands” can also be a valuable tool for traders who like to exploit trend exhaustion by helping to identify the turn in price. Note, however, that counter-trend trading requires far larger margins of error, as trends will often make several attempts at continuation before reversing.

Here, the strategy is generally to go short, with a stop above the most recent highs. With the W-bottom, the general strategy is to go long on the trade and to place a stop just below the most recent lows to help minimize potential losses. To understand them, let’s first get acquainted with their creator John Bollinger.
