Bollinger Bands Explained Video

Check out this quick video on bollinger bands. The video will help you familiarize yourself with the indicator and provide a general overview of trade setups before we dig into the advanced strategies.

 

Odds are you have landed on this page in search of bollinger band trading strategies, secrets, best bands to use, or my favorite - the art of the bollinger band squeeze.

Before you skip down to the section titled bollinger band trading strategies which covers all these topics and more; let me impart two additional resources on Tradingsim: (1) Trading Simulator (you will need to practice what you have learned) and (2) Indicators Category (confirming your bollinger band strategy with another indicator is always a plus).

At the end of this article, you will not only learn six bollinger band trading strategies, but more importantly, you will understand which strategy best matches your trading profile.

Bollinger Bands Indicator

Bollinger bands are a powerful technical indicator created by John Bollinger.  Some traders will swear that solely trading a bollinger bands strategy is the key to their success.

Bollinger bands encapsulate the price movement of a stock. It provides relative boundaries of highs and lows. The crux of the bollinger band indicator is based on a moving average that defines the intermediate-term "trend" of the stock based on the trading time frame you are viewing.

This trend indicator is known as the middle band. Most stock charting applications use a 20-period moving average for the default bollinger bands settings. The upper and lower bands are then a measure of volatility to the upside and downside. They are calculated as two standard deviations from the middle band.

Bollinger Bands Calculation:

Upper Band = Middle band + 2 standard deviations

Middle Band = 20-period moving average (most charting packages use the simple moving average)
Lower Band
= Middle band - 2 standard deviations.

The below chart illustrates the upper and lower bands.

Bollinger Band Trading Strategies

Many of you have heard of popular technical analysis patterns such as double tops, double bottoms, ascending triangles, symmetrical triangles, head and shoulders top or bottom, etc. The bollinger bands indicator can add that extra bit of firepower to your analysis by assessing the potential strength of these formations.

Bollinger bands can help you understand whether or not the stock is trending, or even if it is volatile enough for your investment. On occasion when trading with bollinger bands, you will see the bands coiling tightly which indicates the stock is trading in a narrow range.

This coiling action is the trigger to watch for a price breakout or breakdown. Many times, large rallies begin from low volatility ranges. When this happens, it is referred to as "building cause."

This is the calm before the storm.

Let me stop there, I feel myself starting to reveal aspects of the trading strategies.

Bollinger Bands Infographic

Before we jump into the strategies, take a look at the below infographic titled '15 Things to Know about Bollinger Bands'.

The information contained in the graphic will help you better understand the more advanced techniques detailed later in this article.

#1 Strategy - Double Bottoms and Bollinger Bands

Double Bottoms

Double Bottoms

A common bollinger band strategy involves a double bottom setup.

The initial bottom of this formation tends to have substantial volume and a sharp price pullback that closes outside of the lower bollinger band. These types of moves typically lead to what is called an "automatic rally." The high of the automatic rally tends to serve as the first level of resistance in the base building process that occurs before the stock moves higher.

After the rally commences, the price attempts to retest the most recent lows that have been set to test the vigor of the buying pressure that came in at that bottom.

Many bollinger band technicians look for this retest bar to print inside the lower band. This indicates that the downward pressure in the stock has subsided and there is a shift from sellers to buyers. Also, pay close attention to the volume; you need to see it drop off dramatically.

Below is an example of the double bottom outside of the lower band which generates an automatic rally.  The setup in question was for FSLR from June 30, 2011.  The stock hit a new low with a 40% drop in traffic from the last swing low.  To top things off, the candlestick struggled to close outside of the bands.  This led to a sharp 12% rally over the next two days.

#2 Strategy - Reversals with Bollinger Bands

Another simple, yet effective trading method is fading stocks when they begin printing outside of the bands.  Now, let's take that one step further and apply a little candlestick analysis to this strategy.

For example, instead of shorting a stock as it gaps up through its upper band limit, wait to see how that stock performs.  If the stock gaps up and then closes near its low and is still completely outside of the bollinger bands, this is often a good indicator that the stock will correct on the near-term.

You can then take a short position with three target exit areas: (1) upper band, (2) middle band or (3) lower band.  In the below chart example, the Direxion Daily Small Cap Bull 3x Shares (TNA) from June 29, 2011, had a nice gap in the morning outside of the bands but closed 1 penny off the low.

As you can see in the chart, the candlestick looked terrible.  The stock quickly rolled over and took an almost 2% dive in under 30 minutes.

#3 Strategy - Riding the Bands

Riding the Bands

Riding the Bands

The single biggest mistake that many bollinger band novices make is that they sell the stock when the price touches the upper band or buy when it reaches the lower band.

Bollinger himself stated that a touch of the upper band or lower band does not constitute a bollinger band signals of buy or sell.

Not only have I seen, but I have also traded the riding the bands strategy as a continuation setup.

Take a look at the example below and notice the tightening of the bollinger bands right before the breakout.

To my earlier point, price penetration of the bands alone cannot be considered a reason to short or sell a stock.

Notice how the volume exploded on the breakout and the price began to trend outside of the bands. These can be hugely profitable setups, if you give them room to fly.

BSC Bollinger Band Example

BSC Bollinger Band Example

I want to touch on the middle band again. Just as a reminder, the middle band is set as a 20-period simple moving average in many charting applications.

Every stock is different, and some will respect the 20 period and some will not. In some cases, you will need to modify the simple moving average to a number that the stock respects. This is curve fitting, but we want to put the odds in our favor.

While curve fitting can work, you have to make sure you don't go crazy with analyzing corky settings.

At any rate, the middle line can represent areas of support on pullbacks when the stock is riding the bands. You could even increase your position in the stock when the price pulls back to the middle line.

Conversely, the failure for the stock to continue to accelerate outside of the bollinger bands indicates a weakening in the strength of the stock. This would be a good time to think about scaling out of a position or getting out entirely.

Additionally, we should look for higher highs and higher lows as we ride the Bollinger bands.

#4 Strategy - Bollinger Band Squeeze

Another bollinger bands trading strategy is to gauge the initiation of an upcoming squeeze.

John created an indicator known as the band width. This bollinger band width formula is simply (Upper Bollinger Band Value - Lower Bollinger Band Value) / Middle Bollinger Band Value (Simple moving average).

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. This squeezing action of the bollinger band indicator foreshadows a big move. You can use additional signs such as volume expanding, or the accumulation distribution indicator turning up.

These other indications add more evidence of a potential bollinger band squeeze.

We need to have an edge though when trading a bollinger band squeeze because these types of setups can head-fake the best of us.

Notice above in the BSC chart (#3 Strategy) how the bollinger price expanded on the opening of 9/26.

It immediately reversed, and all the breakout traders were head faked. You don't have to squeeze every penny out of a trade. Wait for some confirmation of the breakout and then go with it. If you are right, it will go much further in your direction. Notice how the price and volume broke when approaching the head fake highs (yellow line).

To the point of waiting for confirmation, let's take a look at how to use the power of a bollinger band squeeze to our advantage.  Below is a 5-minute chart of Research in Motion Limited (RIMM) from June 17, 2011.  Notice how leading up to the morning gap the bands were extremely tight.

Tight Bollinger Bands

Tight Bollinger Bands

Now some traders can take the elementary trading approach of shorting the stock on the open with the assumption that the amount of energy developed during the tightness of the bands will carry the stock much lower.  Another approach is to wait for confirmation of this belief.

So, the way to handle this sort of setup is to (1) wait for the candlestick to come back inside of the bollinger bands and (2) make sure there are a few inside bars that do not break the low of the first bar and (3) short on the break of the low of the first candlestick.

Based on reading these three requirements you can imagine this does not happen very often in the market, but when it does, it's something else.  The below chart depicts this approach.

Bollinger Bands Gap Down Strategy

Bollinger Bands Gap Down Strategy

Now let's take a look at the same sort of setup but on the long side.  Below is a snapshot of Google from April 26, 2011.  Notice how GOOG gapped up over the upper band on the open, had a small retracement back inside of the bands, then later exceeded the high of the first candlestick.  These sort of setups can prove powerful if they end up riding the bands.

Bollinger Bands Gap Up Strategy

#5 Strategy - Snap Back to the Middle of the Bands

This strategy is for those of us that 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.

What I like about this strategy is that you will bat a high winning percentage over time.

You are not obsessed with getting in a position and it wildly swinging in your favor. Nor are you looking to be a prophet of sorts and try to predict how far a stock should or should not run.

By not asking for much, you will be able to safely pull money out of the market on a consistent basis and ultimately reduce the wild fluctuations of your account balance, which is common for traders that take big risks.

Middle of the Bands

Middle of the Bands

The key to this strategy is waiting on a test of the mid-line before entering the position.  You can increase your likelihood of placing a winning trade if you go in the direction of the primary trend and there is a sizable amount of volatility.

As you can see in the above example, notice how the stock had a sharp run-up, only to pull back to the mid-line.  You would want to enter the position after the failed attempt to break to the downside.

You can then sell the position on a test of the upper band.  If you have more of an appetite for risk, you can ride the bands to determine where to exit the position.

#6 Strategy - Trade Inside the Bands

This is honestly my favorite of the strategies. If I gave you any other indication that I preferred one of the other signals, forget whatever I said earlier.

The majority of the money to be made in the market, with minimal risk is in the margins.

The same way we say football is a game of inches, trading is the same.

You, of course, can make a ton of money placing big bets, but these types of traders do not make it over a long trading career (20+ years).

First, you need to find a stock that is stuck in a trading range. The greater the range, the better.

Bollinger Bands Range

Bollinger Bands Range

Now, looking at this chart, I feel a sense of boredom coming over me. That's because it's far more entertaining to tell yourself and others you crushed a 20% day trade in one day.

However, from my experience, the guys that take money out of the market when it presents itself, are the ones sitting with a big pile of cash at the end of the day.

In the above example, you just buy when a stock tests the low end of its range and the lower band. Conversely, you sell when the stock tests the high of the range and the upper band.

The key to this strategy is a stock having a clearly defined trading range. This way you are not trading the bands blindly, but are using the bands as a means to gauge when a stock has gone too far.

You could argue that you don't need the bands to execute this strategy. However, by having the bands, you can validate that a security is actually in a flat or low volatility phase, by reviewing the look and feel of the bands.

A simpler way of saying this is that the bands help validate that the stock is stuck in a range.

So, instead of trying to win big, you just play the range and collect all your pennies on each price swing of the stock.

Which Strategy Works Best?

This is the obvious question for anyone reading this article.

For me, it's strategy number 6 hands down, because you are constantly taking money out of the market and it has a high winning percentage.

How do I know it has a high winning percentage?

Because you are not asking much from the market in terms of price movement. From my personal experience of placing thousands of trades, the more profit you search for in the market, the less likely you will be right.

Now, while strategy 6 works best for me, but what about the rest of you?

Since trading is a personal journey, some of the other approaches may work best for your risk profile.

Below is a quick list of the trading styles and which ones are best aligned to the six strategies covered in this article:

  1. Strategy #1 Double Bottoms - this is for the pure technician.  The trader that is going to scan the entire market looking for a particular setup. This will require a ton of patience to identify the setup, since you really need the second bottom to breach the bands to generate a powerful buy signal.
  2. Strategy #2 Reversals - calling all of my risk takers. This approach is fantastic when you get it right, because the reversal  will pour money into your account. However, get things wrong, and the pain can often leave you paralyzed from taking any action. You have to be quick on your toes and willing to cut a loser without blinking.
  3. Strategy #3 Riding the Bands - this is for all my home run hitters out there. You must have the sheer will to only average a 20% to 30% win ratio because you will make all of your money on the big moves. That sounds easy, doesn't it? Well, I have tried systems that have low win percentages and I have failed every time. This is because I am a sore loser. Therefore, I can't handle being wrong that infrequently. So, if you want to take less action and can seriously handle being wrong eight out of ten times, this system will be perfect for you.
  4. Strategy #4 The Squeeze - this for me is the best setup for the traders that want the profit potential of riding the bands, but are able to take quick money as things go in your favor. You can take one of two approaches with the squeeze strategy.  For the riskier traders, you can jump in before the break and capture all of the gains. More conservative traders can wait for the break and then look for a pullback setup in the direction of the primary trend.
  5. Strategy #5 Playing the Moving Average - this strategy is for all of the pullback traders. You are looking for stocks that are trending strongly and then have a reaction 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.
  6. Strategy #6 Trading the Range - I think I have already praised this one enough. For me, it comes down to the simple fact markets are range bound 80% of the time. So, if you need thrills, this strategy will put you to sleep. You will likely want to focus on #2, #3, or #4.

What to Do When the Bands Fail?

Like anything else in the market, there are no guarantees. Bollinger bands can be a great tool for identifying volatility in a security, but it can also prove to be a nightmare when it comes to newbie traders. Don't skip ahead, but I will touch on this from my personal experience a little later in this article.

Like any other trade signal, you will need to exit your position without reservation.

Not exiting your trade can almost prove disastrous as three of the aforementioned strategies are trying to capture the benefits of a volatility spike.

For example, imagine you are short a stock that reverses back to the highs and begins riding the bands. What would you do?

Let me help you out if you are confused - kill the trade!

While bands do a great job of encapsulating price movement, it only takes one extremely volatile stock to show you the bands are nothing more than man's failed attempt to control the uncontrollable.

Bonus Content

In addition to strategies, there are a few items related to bollinger bands I need to cover that will provide you with a full picture of the indicator.  These are not hard fast rules, but things you need to consider as you validate if the indicator is a good fit for you and your trading style.

What are the Ideal Bollinger Bands Settings?

Regardless of the trading platform, you will likely see a settings window similar to the following when logging into the application.

Bollinger Bands Settings

Bollinger Bands Settings

If you are new to trading, you are going to lose money at some point. This process of losing money often leads to over-analysis. While technical analysis affords us the ability to identify things unseen on a ticker, it can also aid in our demise.

In the old times, there was little to analyze. Therefore, you could tweak your system to a degree, but not in the way we can continually tweak and refine our trading approach today.

Case in point, the settings of the bollinger bands indicator. While the configuration is far simpler than many other indicators, it still provides you the ability to run unlimited optimization tests to try and squeeze out the last bit of juice from the stock.

The problem with this approach is after you change the length to 19.9 (yes people will go to decimals), 35 and back down to 20; it still comes down to your ability to manage your money and book a profit.

My strong advice to you is to not tweak the settings at all. It's actually better to stick with 20, as this is the setting all the traders are using anyways to make their decisions.

I always like to know what's coming at me versus trying to look for some secret setting that does not exist.

Bollinger Bands Width

Pairing the bollinger band width indicator with bollinger bands is like combining the perfect red wine and meat combo you can find.

In the previous section, we talked about staying away from changing the settings. Well, if you really think about it, your entire reasoning for changing the settings in the first place is in hopes of identifying how a particular security is likely to move based on its volatility.

A much easier way of doing this is to use the bollinger bands width. In short the the bb width indicator measures the spread of the bands to the moving average to gauge the volatility of a stock.

Why is this important to you?

Well, now you have an actual reading of the volatility of a security, which you can then use to look back over months or years to see if there is any repeatable patterns of how price reacts when it hits extremes.

Still don't believe me? Take a look at the below screenshot using both the bollinger bands and bollinger band width.

Third Time's the Charm - Bollinger Band Width

Third Time's the Charm - Bollinger Band Width

Notice how the bollinger band width tested the .0087 level three times. The other point of note is that on each prior test, the high of the indicator made a new high, which implied the volatility was expanding after each quiet period.

As a trader, you need to separate the idea of a low reading with the bollinger bands width indicator with the decrease in price.

Remember, bollinger band width are informing you that a pending move is coming, the direction and strength are up to the market.

In this example, Sciclone Pharmaceuticals (SCLN) had a huge runup from $9.75 to 11.12.

Did I fail to mention this is a 5-minute chart of SCLN?

If you had just looked at the bollinger bands, it would be nearly impossible to know that a pending move was coming. You would have no way of knowing that .0087 was a level that existed, let alone a level that could trigger such a large price movement.

This is just another example of why it's important to pair bollinger bands with other indicators and not use it as a standalone tool.

My Personal Experience with Bollinger Bands

I think it's safe to say bollinger bands is probably one of the most popular technical indicators in any trading platform

If my memory serves me correctly, bollinger bands, moving averages and volume were likely my first taste of the life.

Well as of today, I no longer use bollinger bands in my trading.  That doesn't mean that they can't work for you, I just found that my trading style requires me to use a clean chart.

So, how did I end up abandoning the bands? Well, let me dig a little deeper so you can understand my rationale.

I tend to over analyze setups; it's what I do.

Therefore, the more signals I have on a chart, the more likely I am to feel the need to take action in response to said signal. This is where the bollinger bands expose my trading flaw.

For example, if a stock explodes above the bands, what do you think is running through my mind? You guessed right, sell!

In reality, the stock could just be starting its glorious move to the heavens, but I am unable to mentally handle the move because all I could think about was the stock needed to come back inside of the bands.

Day Trading in 2007

Flashback to 2007 when I was just starting out in day trading; I had no idea what I was doing.

Instead of taking the time to practice, I was determined to turn a profit immediately and was testing out different ideas.

One of the first ideas I put to the test was bollinger bands.

Why? It's one of the most popular indicators.

I decided to scalp trade, and I would sell every time the price hit the top bands and buy when it hit the lower band. I know, don't judge me, it's pretty bad.

From what I remember, I tried this technique for about a week, and at the end of this test, I had made Tradestation rich with commissions.

The key flaw in my approach is that I did not combine bollinger bands with any other indicator. This left me putting on so many trades that at the end day, my head was spinning.

What it Takes to Trade with Bollinger Bands

To harness the power of bollinger bands; you need to learn how the bands interact with the price of a security. At the end of the day, bollinger bands are a means for measuring volatility. So, it's not something you can just pick up and use for buy and sell signals.

Just as you need to learn specific price patterns, you also need to find out how bollinger bands respond to certain price movements.

This ability to identify the setups will help you avoid the false signals from the real ones.

This level of mastery only comes from placing hundreds if not thousands of trades with the same markets on the same time frame.

Bollinger Bands in the Trading Community

I went onto Amazon to search for the most popular books to see who the leaders are in the space.

No surprise, John Bollinger had the most popular book - "Bollinger on Bollinger Bands."

The thing that surprised me is that I couldn't find many other famous authors or experts in the space. I'm not sure if this is because there aren't many people interested or if other traders stay out of the bollinger bands arena because John is so actively evangelizing the bands.

The books I did find were written by "basement authors" and honestly have less material than what I have composed in this article. The other hint that made me think these authors were not legit, is their lack of the registered trademark symbol after the bollinger bands title, which is required by John for anything published related to bollinger bands.

Conversely, when I search on Elliott Wave, I find a host of books and studies both on the web and in the Amazon store.

I am still unsure what this means exactly.  With there being million of retail traders in the world, I have to believe there are a few that are crushing the market using bollinger bands.

I just struggled to find any real thought leaders outside of John. I write this not to discredit or credit trading with bands, just to inform you of how bollinger bands are perceived in the trading community.

What are the Best Time Frames for Trading with Bollinger Bands?

Bollinger bands work well on all time frames. Remember, price action performs the same, just the scales of the moves are different.

What are the Best Markets for Bollinger Bands?

Without a doubt, the best market for bollinger bands is Forex.  I say this because currencies tend to move in a methodical fashion allowing you to measure the bands and size up the trade effectively.

Next, I would rank futures because again you can begin to master the movement of a particular contract.

Last on the list would be equities. The captain obvious reason for this one is due to the unlimited trading opportunities you have at your fingertips.

It's one thing to know how the e-mini contract will respond to the lower band while in a five-day trading range.

It's an entirely different story to have to size up one stock from the next in terms of how well a given security responds to the bands. There will be some stocks that simply do not care and do whatever the want.

Conclusion

These are but a few of the great methods for trading bollinger bands.

The key point again is bollinger bands gets you in the habit of thinking about volatility.

You will need to do the following to take your bollinger bands trading to the next level:

  1. Settle on a market you want to master (i.e. futures, equities, forex). If you try to learn all three at the same time, you are going down a painful road.
  2. Figure out what time frame works best for you.
  3. Learn to master one strategy before attempting to tackle them all. Any of the strategies mentioned in this article can work given the right market environment and your willingness to stick to your trading plan. However, similar to points one and two above, learn how to focus on getting one thing right before complicating things.
