Further, the width of the band can be an indicator of its volatility . Certain aspects of Bollinger Bands, such as the Squeeze, work well for currency trading, as does adding a second set of Bollinger Bands. Using this tool correctly can help investors and traders make better decisions and hopefully earn profits. Importantly, however, these conditions should not be taken as trading signals. The bands give no signs of when the change may take place or in which direction the price might move. According to Bollinger, it is necessary to look to other indicators to determine breakout direction. He suggests using the relative strength index along with one or two volume-based indicators such as the intraday intensity index or the accumulation/distribution index.
The chart below shows the VWAP indicator and BB applied on the 15-minute chart of the EUR/USD. The chart below shows the EURUSD with Keltner Channels and BB. For example, as shown below, the Relative Strength Index kept rising together with the Bollinger Bands.
How to Pick Stocks Using Fundamental and Technical Analysis
Conversely, as the bands expand, an increase in price action/market volatility is indicated.

Conversely, the wider apart the bands move, the more likely the chance of a decrease in volatility and the greater the possibility of exiting a trade. The bands give no indication when the change may take place or in which direction the price could move.

But first, let’s review the key Bollinger Band trading signals. Although it is considered as a lagging indicator, it gives some insights as to where volatility is now and where has it been last period (day, week, month, etc.).

Spotting trend reversals
It involves jumping into the bandwagon of an already-existing trend. Another strategy for using Bollinger Bands is to identify breakouts. A breakout is a period where the price of an asset suddenly moves in either direction after a period of consolidation. I believe we’re on the verge of entering bear market territory if 47k doesn’t hold over the next couple of days and weeks. On the second drop, even as the price sets a lower low, the closing price remains above the lower Bollinger Band . The stock breaks out once it surpasses the previous high in the W pattern, and the breakout is confirmed with a bullish signal line crossover in the MACD. The olive green arrow in July 2016, when MSFT closed above the upper band, is therefore not an entry signal as the October 2015 trade is still open.
Since the bandwidth contracts and widens with volatility, it helps traders take advantage of oversold and overbought conditions. By confirming the price action, Bollinger Bands provide traders with information on whether they should make buying or selling orders. For instance, a sell trade should be carried out at the upper band limit; entering a buy trade is advisable at the lower band limit. If a currency normally follows a range pattern, this method will be useful.

- In conclusion, it is important to note that Bollinger Bands are just one part of trading.
- The look-back period for the standard deviation is the same as for the simple moving average.
- Signals based on the distance between the upper and lower band, including the popular Bollinger Band Squeeze, are identified using the related Bollinger BandWidth indicator.
- Volume in candle 2 increased at the moment of the breakout and it could be assumed that it was a true breakout.
- Double tops, head-and-shoulders patterns, and diamonds represent evolving tops.
As a volatility indicator, Bollinger Bands tighten or broaden around the price plot on the chart. As seen in the formula above, the price range widens as the standard deviation goes up and vice versa. For example, when the volatility of a given currency pair is low, the channel narrows down.

Second, the stock price rebounds to approximately the price of the 20-day simple moving average. Third, the price drops to a lower low, but remains above the lower Bollinger Band this time. Finally, the price should bounce up and then experience a positive breakout once it passes the previous high in the W pattern. The breakout can be confirmed with additional indicators, in particular a signal line crossover in the MACD. Bollinger Bands are straightforward to calculate, as they are simply twice the standard deviation from the 20-day simple moving average.
- When the bands separate by an unusual large amount, volatility increases and any existing trend may be ending.
- When the instrument’s price moves towards the upper band, this is a signal that it is overbought.
- Provided the candles will be closed at the topmost zone, traders should hold long trades or even enter new ones.
- It can similarly serve for both breakout and reversal trades.
- This is because during a strong uptrend or downtrend, prices can often stick within the bands.
Bollinger Bands consist of three lines on a trading chart. The middle line of the indicator is the simple moving average of the instrument’s price, which is the average of the price over a certain length of time. Traders should understand that standard settings will not suit all strategies when trading with Bollinger Bands. For example, long-term position traders may prefer to use a more significant number of periods and a higher standard deviation. In contrast, day traders and swing traders may use a lower number of periods and lower standard deviation.
