They are two intervals drawn to predict potential volatility range for an asset, in relation to a moving average . Normally, these price channels move across the chart symmetrically, but in certain market conditions, the distance between the bands varies What is Infinox significantly. Bollinger Bands demonstrate the prices and volatility over time of a given asset, which is used in a variety of trading strategies. The formula was first introduced by John Bollinger, an American financial analyst, in the 1980s.
The crux of the Bollinger Band indicator is based on a moving average that defines the intermediate-term “trend” based on the time frame you are viewing. touched the lower band and wait to see where the next low occurs.
The breakout in the Bollinger Bands Moving Average is a confirmation signal, which usually comes after a price interaction with the bands. If the price bounces from the upper band and then breaks the 20-period SMA in bearish direction, we get a strong short signal. If the price bounces from the lower band and breaks the 20-period SMA upwards, then we get a strong long signal. When the Bollinger Bands are close to each other, then the trading indicator is conveying to us that the volatility of the Forex pair is relatively low.
Bollinger Bands Overview
Bollinger Bands are a technical analysis tool, specifically a type of trading band or envelope. Over the years there have been many variations on bands and envelopes, some of which are still in use.
- They are calculated as two standard deviations from the middle band.
- One of these limitations is that Bollinger Bands are primarily reactive, not predictive.
- As we can see, prices tracked the lower Bollinger Band very closely.
- The upper and lower bands are then a measure of volatility to the upside and downside.
- Most stock charting applications use a 20-period moving average for the default settings.
- Although Bollinger Bands are helpful tools for technical traders, there are a few limitations that traders should consider before using them.
Many traders mistakenly believe that because a security’s price has touched the upper band they should go short, or vice versa. However, such price movements should not be viewed as signals to sell or buy. A moving average shows the average price of a security over a certain period of time. The basic rule of moving averages is that if a security’s price is above the moving average, the trend is up. Consequently, they are best used alongside other similar technical analysis indicators.
Profitable Bollinger Band Trading Strategies For Fx Markets
Bollinger Bands also help determine overbought and oversold markets. When prices move closer to the upper band, the market is becoming overbought, and as the prices move closer to the lower band, the market is becoming oversold. The market’s price momentum forex should also be taken into account. When a market enters an overbought or oversold area, it may become even more so before it reverses. You should always look for evidence of price weakening or strengthening before anticipating a market reversal.
Soon we see the price action creating a bullish Tweezers reversal candlestick pattern, which is shown in the green circle on the image. This is a strong long signal occurring at the lower band, and thus creates a nice opportunity to buy the EUR/USD. A stop loss order should be placed below the lowest point of the Tweezers chart pattern as shown on the image.
Trading Idea
When I started working in the markets percentage bands were the most popular choice. Percentage bands are quite simple, a moving average shifted up and down by a user-specified percent. For example, at any given time a 7% band consists of a base moving average, an upper curve at 107% of the base and a lower curve at 93% of the base. Percentage bands had the decided advantage at the time of being easy to chart by hand.
The narrow bands suggest a period of low volatility often associated with a sideways market environment . Widening bands suggest an increase in volatility often associated with a trending market environment. Volatility is considered cyclical in nature in that a period of low volatility is a precursor to high volatility and vice versa. Combining price breakouts with Bollinger Bands is often referred to as a volatility breakout strategy. The strategy whereby we wait for a narrowing of Bollinger Bands as a precursor to a breakout is known as a Bollinger ‘Squeeze’. Bollinger Bands work best when the middle band is chosen to reflect the intermediate-term trend, so that trend information is effectively combined with relative price level information.

In this manner, the trading volumes are typically low as well, and the pair is said to be consolidating or ranging rather than trending. This is what we call a Bollinger Band squeeze, because the bands are being “squeezed” tightly together. In most cases, we should avoid trading within very tight price ranges, because they provide significantly less profitable opportunities than during trending phases. The middle line is the instrument’s moving average, while the upper and lower lines are based on the standard deviation of the price movements. Bollinger Bands are an effective technical analysis indicator, however, they do have limitations. Bollinger Bands are based on an instrument’s simple moving average, which uses past data points.
In this approach, a chart top occurring above the upper band followed by a top below the upper band generates a sell signal. Likewise, a chart bottom occurring below the lower band followed by a bottom above the lower band generates a buy signal. Strategy #5 Playing the Moving Average https://forexarena.net/ – this strategy is for all of the pullback traders. You are looking for stocks that are trending strongly and then react back to the 20-period moving average. This setup works lovely when day trading the Nikkei and usually develops a little after forty-five minutes into the session.
Bollinger bands can be useful indicators of a trend in a market – strong trends cause volatility, which is easy to see as the Bollinger bands widen and narrow. Traders also look for Bollinger ‘squeezes’ and Bollinger ‘bounces’, which are used as indicators for levels of support and resistance. Squeezes – when the upper and lower band contract toward the moving average – could show that there is about to be a breakout of the asset’s price.
Experience The Excitement Of Trading!
The big black arrow on the chart shows a Bollinger Band squeeze. The bands are relatively close to each other squeezing the price action and the indicator. Suddenly, the bands start expanding rapidly during the decrease.
Since then, these statistical charts have been utilized to analyze the market data, inform trading decisions and manage algorithmic trading. In my opinion, the better Bollinger Bands trading strategy is the second setup I showed you. The reason for this is that Volatility and Volumes are mutually connected.
As a result, the bands will always react to price moves, and not forecast them. In other words, Bollinger Bands are reactive, not predictive.
Therefore, their importance to each other is essential, which in turn, creates reliable signals for trading. When the price is moving strongly beyond one of the bands during high volatility and high trading volumes, then we are likely to see a big price move on the horizon. At the beginning of the chart we see the price moving below the 20-period Bollinger Band SMA. However, the two Bollinger Bands are very tight and the volumes are relatively low. Therefore, we would stay out of the market for the time being. Suddenly, the two bands start expanding which is shown by the pink lines on the image. At the same time, the three black arrows point toward an increase in the trading volumes of the USD/JPY. For this reason, we consider this as a nice opportunity for a short position in the Yen.
