This squeezing action of the Bollinger Band indicator often foreshadows a big move. To the earlier point, price penetration of the bands alone cannot be a reason to short or sell a stock. The first bottom of this formation tends to have substantial volume and a sharp price pullback that closes outside of the lower Bollinger Band.

As the chart above shows, the bands have actually widened since late December. Bollinger Bands are one tool that can help you decide when to make your move by illustrating the relative strength—or momentum—of a stock or other investment. You can even apply this indicator to the broad market.

How Bollinger Bands Indicator Works

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 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.

This concept is the basis for the “overbought” and “oversold” strategies. The earliest example of trading bands that I have been able to uncover comes from Wilfrid Ledoux in 1960. He used curves connecting the monthly highs and lows of the Dow Jones Industrial Average as a long-term market-timing tool. After Ledoux the exact sequence of trading band development gets foggy. M. Hurst who used cycles to draw envelopes around the price structure. Hurst’s work was so elegant that it became a sort of grail with many trying to replicate it, but few succeeding.

Trend Trading Indicator Strategy

This is the only way you can understand whether this indicator is useful to you or not. The Bollinger Bands indicator works on the basis of a moving average. The upper and lower levels are equidistant from the MA. The lag rate is calculated using the standard deviation multiplied by the specified factor. The latter depends on the length of the moving average.

Investors make purchases after a repeat testing without much stress and soon get the expected profit. W-bottom is the most common pattern of transition to the bullish market. It is rarely seen in its pure form and often has a variety of deviations from the ideal shape. For the rest of the figures – M7, M9, M12, M14, W1, W3, W5, W8, W10 – signals are generated based on the general rules described below for W and M shapes.

You see that the distance between bands is wider than in the previous chart. Moreover, the upper and lower bands are smoother than the “32-period” moving average Bollinger Bands. I think it is not a good idea to recommend a specific MA. Recommending a specific number for a moving average is difficult due to many factors that affect your analysis, such as mentality, emotional strength, assets, etc.

How do you add Bollinger bands when you’re trading?

John Bollinger explains that Bollinger Bands are not a standalone indicator and should always be used in combination with others. If you’re brave, you can also write manually the formula for each value in order to test it and calculate it truly manually, but that’s a waste of time. Every time we do the formula we need to insert in X each number one at a time.

The neckline in the right shoulder often stops at the moving average, and the first decline is in the vicinity of the lower Bollinger band. The most common case of a triple top is the head and shoulders pattern, which is well known in technical analysis. It is followed by another period of growth, which forms a new high, which ends with an even larger rollback. Quite often, this rollback completes near the previous local low. As for the interaction of the W-bottom with the BB, in most cases the left side of the pattern will touch the lower line or cross it. The growth following the local low will again return the candles to the inner zone of the bands.

Bars closing outside the bands are statistically more likely to indicate the continuation of the trend, rather than its end. When the trend develops, we move the stop loss to a breakeven position . For clarity, I marked the initial stop level with a transparent red line. Colors – here you can set up the color, thickness and look of the indicator line. By default, it is bright yellow, so it is better to immediately change it to a more vivid color. First, let’s add Bollinger Bands and RSI to the EURUSD chart of LiteFinance online terminal.

• The blue arrows mark the candlestick in which the Bollinger Bands %b ranges from 0 to 0.2, and the MFI chart is just below 20.
• In range-bound markets, mean reversion strategies can work well, as prices travel between the two bands like a bouncing ball.
• Or, on the other hand, sell every time the price hits the upper band.
• The distance between the upper and lower band is determined by standard deviations.

During such times, the price may bounce off both the upper and lower band. In those cases, it isn’t necessarily a reversal signal. The narrow bands are just closer to the price and thus likely to be touched. The pullback doesn’t have to stall out near the middle line, but it does show selling strength if it does. Even during an uptrend prices drop for periods of time, known as pullbacks. During an uptrend, if the price is moving strongly then pullback lows will typically occur near or above the moving average line.

The first step in calculating Bollinger Bands® is to compute the simple moving average of the security in question, typically using a 20-day SMA. A 20-day moving average would average out theclosing pricesfor the first 20 days as the first data point. The next data point would drop the earliest price, add the price on day 21 and take the average, and so on. Next, the standard deviation of the security’s price will be obtained.

First, the stock formed a reaction low in January and broke below the lower band. Second, there was a bounce back above the middle band. Third, the stock moved below its January low and held above the lower band. Even though the 5-Feb spike low broke the lower band, the signal is not affected since, like Bollinger Bands, it is calculated using closing prices. Fourth, the stock surged with expanding volume in late February and broke above the early February high. Chart 3 shows Sandisk with a smaller W-Bottom in July-August 2009.

Relative Strength Index (RSI): Calculation & How to Trade It?

The trader decides the number of standard deviations they need the volatility indicator set at. The number of standard deviations, in turn, determines the distance between the middle band and the upper and lower bands. The position of these bands provides information on how strong features of group insurance policy the trend is and the potential high and low price levels that may be expected in the immediate future. The Bollinger bands trading strategy is used to know the value of price levels. This strategy is used for short term trading purpose and can also be used for long term.

To simplify the calculations, let’s take a period of 10 bars. After selecting the multiplier and the period, you can calculate the Bollinger bands themselves. It will draw real-time zones that show you where the price is likely to test in the future. For each type of trading, there are different settings. It’s not advisable to base yourself solely on Bollinger Bands in order to make trading decisions.

The standard Bollinger Bands formula uses a 20-day SMA for the middle line, while the other two are calculated based on volatility compared to the SMA. You can always modify this setting according to your trading preferences. This is because trending markets can sometimes ride the bands for a long time and suddenly stop existing trades using the cheap/expensive model. That’s why you should always use another indicator, such as the Relative Strength Index , to confirm the “squeeze” and “bounce” of both upper and lower bands.

This way you are not trading the bands blindly but are using the bands to gauge when a stock has gone too far. This strategy is for those of us who like to ask for very little from the markets. Essentially you are waiting for the market to bounce off the bands back to the middle line, which carries a high winning percentage over time. The idea, using daily charts, is that when the indicator reaches its lowest level in 6 months, you can expect the volatility to increase. This goes back to the tightening of the bands that I mentioned above.
