Bollinger Bands Explained: Trading Strategy, Formula, Calculation and More

Bollinger Bands, a powerful and versatile technical analysis tool, offer traders a unique framework for developing effective trading ig broker review strategies. There are several, including the Keltner channels, moving average envelopes, the Donchian channels, the average true range, and the standard deviation indicator. A contraction of the bands suggests that the market is experiencing less volatility. Price movements are more contained, and there may be less trading volume or market interest in the short term. This reduced volatility period can be seen as a time of consolidation. When the bands widen, this signals an increase in volatility because the standard deviation of the price increases.

The Bollinger Band width determines the strictness of your entry or exit. If you want to have a stricter entry, then you use a larger standard deviation multiple 2 – 4 standard deviations. If you want to have a very easy signal that gets you in or out quickly and easily without much movement, then you’ll want to use a narrower standard deviation multiple. Bollinger Bands are a relatively simple trading tool and are incredibly popular with professional as well as at-home traders.

Bollinger Bands Example

For the lower band, subtract the standard deviation from the moving average. Buying on the break of the lower Bollinger Band is a simple strategy that often works. In every scenario, the break of the lower band was in oversold territory. Stocks that break the lower Bollinger Band and enter oversold territory face heavy selling pressure. When this pressure is not corrected, the stocks continued to make new lows and continue into oversold territory. Stop-loss orders are the best way to protect you from a stock that will continue to ride the lower band down and make new lows.

How to Calculate Bollinger Bands ?

  • The bands are used to generate signals for securities that are oversold or overbought.
  • Bollinger Bands are a technical indicator that helps to identify potential support and resistance levels in the market.
  • Trending prices can continue to “walk” along the upper or lower bands for an extended time.
  • Developed in the 1980s by financial analyst John Bollinger, the bands appear on stock charts as three lines that move with the price.
  • When the lower band turns upward, it suggests that the uptrend is losing strength.

Therefore, the distance between the bands increases or decreases with price movement — widening when the volatility increases and constricting when it decreases. Even a novice trader can get a lot of information just from the position of bands. Because Bollinger Bands are a particularly visual technical indicator, those dynamic changes in volatility are easy to see on a price chart, especially at the extremes. Some traders incorporate these visual cues into their strategies by analyzing band width—as well as where price is in relation to the bands—and then combining this analysis with other indicators.

  • On the other hand, when they continually touch the lower band, the market is perhaps oversold, triggering a buy signal.
  • Since the SMA is essentially an average and the price keeps swinging from one side of the SMA to the other, you are bound to end up with a profit.
  • A strong uptrend confirmed by Bollinger Bands can be a good occasion to open long positions.
  • For example, when the security’s price continually touches the upper Bollinger Band, the market is thought to be overbought and due for a sell.

Unlike a percentage calculation from a normal moving average, Bollinger Bands® simply add and subtract a standard deviation calculation. If there’s a Bollinger Band squeeze in an uptrend, you’re not going short because the probability is lying to breakout to the upside. Instead you’re using the primary trend and the squeezing together of cmc markets review the bands to position yourself in anticipation of getting a breakout like this. If you do that, you’re getting a very low-risk entry because you’re entering when volatility is low.

Setting your stop loss level this way is really powerful because your stop-loss is linked to the volatility of the stock. A very wildly volatile stock will have a wide stop-loss because the standard deviation is high. A very quiet, calm stock will have a tighter stop-loss because the standard deviation is lower. The longer the number of periods in the Bollinger Band calculation, the smoother the bands are and the slower it is to react.
