Bollinger Bands Indicator Strategy

Bollinger Bands

Bollinger Bands® is a popular technical analysis tool that indicates whether the price of an instrument is high or low relative to its peers. Bollinger Bands, which were invented by John Bollinger in the 1980s, can be applied to a wide range of financial instruments. Indexes, currencies, and stocks are examples of these.

Bollinger Bands, as a technical indicator, show when an instrument is overbought or oversold. If the price of the instrument moves towards the upper band, it is usually a sign that it is overbought. When the price moves towards the lower band, it usually indicates that it has been oversold. They can also be used to predict volatility. During periods of calm trading, the bands will narrow. The bands will widen when price movements are volatile. Bollinger Bands are a popular technical analysis tool. When combined with other indicators, they can assist traders in profiting from overbought and oversold market conditions.

What exactly are Bollinger Bands?

Bollinger Bands are a technical analysis indicator that can be used to determine whether an instrument in the financial markets is overbought or oversold, as well as to assess volatility. Bollinger Bands are three lines drawn on a trading chart. The indicator’s middle line is the simple moving average (SMA) of the instrument’s price, which is the average of the price over a set period of time. This is usually set to a period of 20 days. The upper band is comprised of the SMA plus two standard deviations. The lower band represents the SMA less two standard deviations.

A Bollinger Band can be found on either side of the SMA. Bollinger Bands resemble an envelope enclosing the instrument’s price. The standard deviation determines the widths of the bands. The volatility of the instrument’s price movements is denoted by the standard deviation. In most cases, this is set to 2.0.

Calculating the Bollinger Bands

The period is the number of intervals used to calculate the Bollinger Band. A setting of (20, 2) indicates that the period and standard deviation are both set to 20 and 2.0. The bands for Bollinger Bands with a setting of 20, 2 are calculated using the following formulas:

Upper band = SMA (20-day) + (20-day standard deviation x 2)

Lower band = 20-day simple moving average (SMA) – (20-day standard deviation x 2)

Bollinger Bands: How to Use Them

Bollinger Bands can be applied to any timeframe of a chart, including weekly, daily, and five-minute charts. The settings can be changed to accommodate different trading styles. When the price of the instrument moves towards the upper band, it indicates that it is overbought. Traders generally look to sell when they believe an instrument has been overbought. When the price of the instrument moves towards the lower band, it indicates that it is oversold. Generally, traders seek out securities that have been oversold.

Bollinger Bands are not a perfect trading indicator. They do not always produce reliable signals. As a result, they work best when combined with other similar technical analysis indicators to provide more accurate trading signals. Some of the complementary technical analysis tools available on our Next Generation platform are as follows:

Averages of movement

Moving averages are a well-known trading tool. Traders use these to determine trend direction. A moving average depicts the average price of a security over a given time period. The basic rule of moving averages is that if the price of a security is higher than the moving average, the trend is upward. The trend is downward if the price is below the moving average.

Depending on the trader’s strategy, moving averages can be set to different timeframes. Moving averages can also be classified into several types. A simple moving average (SMA) and an exponential moving average (EMA) are two examples (EMA).

Stochastic indicator

Another well-known technical analysis tool is the stochastic indicator. These can be used to forecast trend reversals. The momentum of price movements is measured by stochastics. Stochastic indicators, like Bollinger Bands, can assist traders in identifying overbought and oversold levels.

The true range on average

The average true range (ATR) is a volatility-measurement technical indicator. Originally developed for commodity analysis, it can now be applied to other instruments such as indices and stocks.

A higher ATR indicates that a security is experiencing a high level of volatility. A low ATR indicates that a security is experiencing low volatility. ATR is used by traders to determine entry and exit points. When combined with other trading indicators, it can be a useful tool.

Keltner’s Channals

Keltner channels, like Bollinger Bands, are volatility-based indicators. The main distinction is that Keltner Channels set band widths based on average true range rather than standard deviation. The middle line in Keltner channels is also an exponential moving average.

On a Euro 50 chart, Bollinger Bands (shown in pink) are compared to Keltner channels (shown in blue).

The strategy of Bollinger Bands

Traders employ a variety of trading strategies when employing Bollinger Bands. Some of the more popular trading strategies that can assist traders in both bear and bull markets are as follows:

Riding the bandwagon

Many traders believe that because a security’s price has touched the upper band, they should sell it, or vice versa. However, such price movements should not be interpreted as buy or sell signals. Price penetration of the bands by itself is not a signal to enter a trade. This is due to the fact that during a strong uptrend or downtrend, prices can frequently remain within the bands.

Squeeze the Bollinger Band

This strategy employs a metric known as ‘band width.’ The following formula is used to calculate band width:

Band width = (upper Bollinger band value – lower Bollinger band value) / middle Bollinger band value

The idea behind this indicator is that when it reaches a six-month low, traders can anticipate an increase in volatility. A squeeze is triggered at this point, and the instrument’s price may move significantly.

What are the most effective Bollinger Bands settings?

Bollinger Bands can be configured for a variety of timeframes and trading strategies. The bands, for example, can monitor movement on hourly, daily, weekly, and monthly charts. A trader looking for long-term price movements in an instrument may prefer to use Bollinger Bands on a monthly chart.

A short-term day trader, on the other hand, may prefer to use Bollinger Bands on a five-minute chart. There is no single best timeframe for Bollinger Bands. The timeframe used will be determined by the trader’s strategy.

Bollinger Bands Patterns

Double Bottoms

A double bottom occurs when the price of an instrument falls sharply, with significant volume, and closes outside the lower Bollinger Band. It will then briefly rebound higher towards the middle band. Finally, it will fall lower once more, but this time on lower volume, and close just inside the lower band.

This pattern indicates that the downward pressure has been relieved. The market is shifting from sellers to buyers. Frequently, the next price movement is a strong upward move off the second low. Traders may decide to go long, aiming for the middle or upper band.

Reversals

In a trend reversal strategy, traders look for signs that the instrument’s price trend will reverse. For example, the price could gap up above the upper Bollinger Band but close near the interval low. This could indicate that the trend will reverse in the near future. The trader may enter a short position with the goal of reaching the middle band. Similarly, the price may fall below its lower Bollinger Band but close near the interval high. This would imply that the trader could go long, aiming for the middle band.

How to Use Bollinger Bands

Bollinger Bands are a useful technical analysis indicator, but they have some limitations. Bollinger Bands are based on a simple moving average of an instrument’s past data points. As a result, the bands will always react to price changes rather than forecasting them. In other words, Bollinger Bands are reactive rather than predictive and are frequently referred to as a lagging indicator rather than a leading indicator.

Bollinger Bands are also prone to generating false signals. A false breakout, for example, occurs when the price of an instrument passes through the trade entry point. It indicates a trade but then reverses its direction. As a result, the trade is a loss.

When using Bollinger Bands, traders should keep in mind that standard settings will not work for all strategies. Long-term position traders may prefer more periods and a higher standard deviation, whereas day traders and swing traders may prefer fewer periods and a lower standard deviation. As a result, the Bollinger Bands indicator works best when combined with other indicators and tools as part of a comprehensive trading strategy.

Summary

In conclusion, Bollinger Bands are an effective technical analysis tool. The bands are used to analyse volatility and trend strength, which is especially useful when opening and closing trades quickly in a volatile market, such as when scalping forex. Bollinger Bands can also be used to forecast trend reversals. Traders should keep in mind that Bollinger Bands are based on historical data. As a result, the bands react to price movements but do not predict future price movements. When trading with Bollinger Bands, you should always consider risk-management controls.
