Bollinger bands measure a standard deviation from the mean or middle. Usually the “mean” or middle is a 21 day moving average of closing price.

Upon selecting Bollinger Bands, the default setting will appear in the parameters window . The first number sets the periods for the simple moving average and the standard deviation. The second number sets the standard deviation multiplier for the upper and lower bands. These default parameters set the bands 2 standard deviations above/below the simple moving average.

How much does trading cost?

Because standard deviation is a measure of volatility, when the markets become more volatile the bands widen; during less volatile periods, the bands contract. Using intraday trading indicators help in averting risk and placing appropriate trades based on technical analysis and market sentiments. Angel Broking offers detailed charts and stock analysis reports that comprise these trading indicators. These tools help in planning an effective trading strategy, while minimizing risks. If short-term averages are exceeding the long-term averages, it indicates a bullish market trend.

A Bollinger Band overlay can be set at (50,2.1) for a longer timeframe or at (10,1.9) for a shorter timeframe. Bollinger Bands reflect direction with the 20-period SMA and volatility with the upper/lower bands. As such, they can be used to determine if prices are relatively high or low. According to Bollinger, the bands should contain 88-89% of price action, which makes a move outside the bands significant. Technically, prices are relatively high when above the upper band and relatively low when below the lower band.

Trading Signals

Traders can also add multiple bands, which helps highlight the strength of price moves. Another way to use the bands is to look for volatility contractions. These contractions are typically followed by significant price breakouts, ideally on large volume.

ADX is normally based on a moving average of the price range over 14 days, depending on the frequency that traders prefer. Note that ADX never shows how a price trend might develop, it simply indicates the strength of the trend. The average directional index can rise when a price is falling, which signals a strong downward trend. As you can see, Bollinger Bands offer tremendous help to determine the direction of the market and decide what trading strategy to use. Many traders learn how to use Bollinger Bands to fade the market, but they can be even more powerful when used to trade trends, and in determining the direction of the market.

Bollinger Bands can be found in SharpCharts as a price overlay. As with a simple bollinger bands tutorial moving average, Bollinger Bands should be shown on top of a price plot.

For short term trading I prefer to use a moving average of 12 bars and a standard deviation of 2 for my settings. In many charting software packages the standard settings for the Bollinger Bands are for the moving average and 2 for the standard deviation. John Bollinger suggests a setting of 9-12, and for me the best setting is 12. There are multiple uses for Bollinger Bands®, including using them for overbought and oversold trade signals.

However, “relatively high” should not be regarded as bearish or as a sell signal. Likewise, “relatively low” should not be considered bullish or as a buy signal. As with other indicators, Bollinger Bands are not meant to be used as a stand-alone tool. Chartists should combine Bollinger Bands with basic trend analysis and other indicators for confirmation. In the chart depicted below, Bollinger Bands® bracket the 20-day SMA of the stock with an upper and lower band along with the daily movements of the stock’s price.

In range-bound markets, mean reversion strategies can work well, as prices travel between the two bands like a bouncing ball. However, Bollinger Bands® don’t always give accurate buy and sell signals.

Standard deviation is a mathematical measurement of average variance and features prominently in statistics, economics, accounting and finance. For a given data set, the standard deviation measures how spread out numbers are from an average value. Standard deviation can be calculated by taking the square root of the variance, which itself is the average of the squared differences of themean. Next, multiply that standard deviation value by two and both add and subtract that amount from each point along the SMA. Trading indicators are mathematical calculations, which are plotted as lines on a price chart and can help traders identify certain signals and trends within the market.

It is about time we saw an application of this powerful trend defining tool. However there are issues with what was claimed to define “exactly” what they are. The upper and lower bands are the standard deviation of the data point in the sample not of the (moving)average. The uncertainty in the average can also be defined by its standard deviation as can the uncertainty in the uncertainty in the uncertainty of the average etc.

In other words, the momentum oscillator helps to understand when the market sentiments are undergoing modifications. By applying the ADX indicator trading rules one can take advantage of the strength bollinger bands of the trend and cash in quick profits. The bottom line is that the best profits come from catching strong trends and the best ADX strategy can help you accomplish your trading goals.
