DESCRIPTION

Abstract Any trader or investor gets benefits to analyze the market by using the method of technical analysis. Bollinger Bands is one of the most important indicators of technical analysis. In this study I have discussed easily about technical analysis, various types of indicators especially Bollinger Bands with example so that any new or old trader or investor can get understand about these fact. Then I have focus on practical implications where I have implemented Bollinger Bands as indicator to analyze ten listed companies of DSE. These ten companies are- LankaBangla Finance Ltd., Meghna Petroleum Ltd., United Airways (BD) Ltd., Jamuna Oil Company Ltd., Padma Oil Company Ltd., Active Fine Chemicals Ltd, Bangladesh Submarine Cable Company Ltd., Islami Bank Bangladesh Ltd., Square Pharmaceutical Ltd., & Titas Gas Transmission & Dist. Co. Ltd. I have also presented a regression analysis for each company. The regressions are done by two variables which are closing price of each company as dependent variable & Index of DSE as independent variable. These regression analyses are done to find dependence of company’s closing price on Index of DSE. Finally, I have presented the Bollinger Bands charts of Index of DSE to highlight the market condition of DSE. At last I expect this study will be a conducive for any new or old trader or investor to analyze their markets.

Chapter 1 Introduction

Background: The methods used to analyze securities and make investment decisions fall into two very broad categories: fundamental analysis and technical analysis. Fundamental analysis involves analyzing the characteristics of a company in order to estimate its value. Technical analysis takes a completely different approach; it doesn't care one bit about the "value" of a company or a commodity. Technicians (sometimes called chartists) are only interested in the price movements in the market. Despite all the fancy and exotic tools it employs, technical analysis really just studies supply and demand in a market in an attempt to determine what direction, or trend, will continue in the future. In other words, technical analysis attempts to understand the emotions in the market by studying the market itself, as opposed to its components. Technical analysis and fundamental analysis are the two main schools of thought in the financial markets. Difference are-

1. A technical analyst approaches a security from the charts, while a fundamental analyst starts with the financial statements. Fundamental analysis takes a relatively long-term approach to analyzing the market compared to technical analysis. While technical analysis can be used on a timeframe of weeks, days or even minutes, fundamental analysis often looks at data over a number of years.

2. Not only is technical analysis more short term in nature than fundamental analysis, but the goals of a purchase (or sale) of a stock are usually different for each approach. In general, technical analysis is used for a trade, whereas fundamental analysis is used to make an investment. Investors buy assets they believe can increase in value, while traders buy assets they believe they can sell to somebody else at a greater price. The line between a trade and an investment can be blurry, but it does characterize a difference between the two schools.

Although technical analysis and fundamental analysis are seen by many as polar opposites - the oil and water of investing - many market participants have experienced great success by combining the two. For example, some fundamental analysts use technical analysis techniques to figure out the best time to enter into an undervalued security. Oftentimes, this situation occurs when the security is severely oversold. By timing entry into a security, the gains on the investment can be greatly improved. Alternatively, some technical traders might look at fundamentals to add strength to a technical signal. For example, if a sell signal is given through technical patterns and indicators, a technical trader might look to reaffirm his or her decision by looking at some key fundamental data. Oftentimes, having both the fundamentals and technical’s on your side can provide the best-case scenario for a trade.

Problem Statement: Although Fundamental analysis is important in analyzing any security, I focus on technical analysis in share price movement of any security. There are many indicators for analyzing the share price movement of any security. Among them Bollinger Bands is another important indicator for analyzing any security. In this study I use Bollinger Bands as indicator to analyze some randomly selected securities of DSE. The main purpose of this study is to verify the feasibility of Technical Analysis by Bollinger Bands on Dhaka Stock Exchange (DSE) and to analyze securities price movement by using Bollinger Bands of Technical analysis. Objectives:

1. To verify the feasibility of Technical Analysis on Dhaka Stock Exchange (DSE) 2. To analyze securities price movement by using Bollinger Bands of Technical analysis. 3. To calculate moving average of price, deviation of price, upper band, & lower band. 4. To show their graphical representation. 5. To identify the upward and downward price movements of selected securities. 6. To calculate the value of %b & to show its graphical representation. 7. To forecast future price range & trend of each security.

Methodology: Research Design Now a day’s DSE is very frequent fluctuate market. Here all the data are historical. For this the given assumptions are built in the base of the historical data. All showed graphs are help to recognize the recent market. This study is very much authentic and realistic. For this any new investor or the old investor can take decision from it. So the research is design in the base of historical data and show the situation of the market. More over the market is now very unpredictable, so the analysis report is very much important for all. The study involved a secondary data about DSE, Dhaka, Bangladesh. Also the companies own website is also helpful for the research. Sources of Data: The data has been collected from Secondary sources. Secondary data sources: Secondary data, such as several academic articles and books have been analyzed to form and clarify the topic of the research, and thus to identify the key variables related to the response and attribution of the entrepreneur in the incidents of the Technical Analysis collecting from DSE and company information. The secondary data sources were- websites, books etc.

Data collection procedure: The data was collected from the secondary market of DSE. Method of Analysis: For implementation & analysis I have taken closing prices of ten listed company then I have done some calculation with excel to find the moving average, deviation, upper band & lower band. Using these data I have found three charts for each company such as-

1. Closing Price Daily, 20-period/2-deviations Bollinger Bands 2. Daily Deviation of closing prices 3. Daily %b of Bollinger Bands

I have also presented a regression analysis for each company. The regressions are done by two variables which are closing price of each company as dependent variable & Index of DSE as independent variable. These regression analyses are done to find dependence of company’s closing price on Index of DSE.

Finally I have presented the Bollinger Bands charts of Index of DSE to highlight the market condition of DSE.  Limitations:

I have taken daily closing price. If I would take longer period, results, interpretation & analysis may defer.

I have used Bollinger Bands as indicator. If I would take another indicator, then interpretation & analysis may defer.

Interpretation depends upon perception of chartists based on charts without considering other socio economical influencing factors.

The technical analysis failed to signal an uptrend or downtrend in time. Report Layout:

Chapter 2 Technical Analysis

Introduction:

Technical Analysis is the forecasting of future financial price movements based on an examination of past price movements. Like weather forecasting, technical analysis does not result in absolute predictions about the future. Instead, technical analysis can help investors anticipate what is "likely" to happen to prices over time. Technical analysis is a method of evaluating securities by analyzing the statistics generated by market activity, such as past prices and volume. Technical analysts do not attempt to measure a security's intrinsic value, but instead use charts and other tools to identify patterns that can suggest future activity.

Just as there are many investment styles on the fundamental side, there are also many different types of technical traders. Some rely on chart patterns; others use technical indicators and oscillators, and most use some combination of the two. In any case, technical analysts' exclusive use of historical price and volume data is what separates them from their fundamental counterparts. Unlike fundamental analysts, technical analysts don't care whether a stock is undervalued - the only thing that matters is a security's past trading data and what information this data can provide about where the security might move in the future. The field of technical analysis is based on three assumptions:

1. The Market Discounts Everything: A major criticism of technical analysis is that it only considers price movement, ignoring the fundamental factors of the company. However, technical analysis assumes that, at any given time, a stock's price reflects everything that has or could affect the company - including fundamental factors. Technical analysts believe that the company's fundamentals, along with broader economic factors and market psychology, are all priced into the stock, removing the need to actually consider these factors separately. This only leaves the analysis of price movement, which technical theory views as a product of the supply and demand for a particular stock in the market.

2. Price Moves in Trends: In technical analysis, price movements are believed to follow trends. This means that after a trend has been established, the future price movement is more likely to be in the same direction as the trend than to be against it. Most technical trading strategies are based on this assumption.

3. History Tends To Repeat Itself: Another important idea in technical analysis is that history tends to repeat itself, mainly in terms of price movement. The repetitive nature of price movements is attributed to market psychology; in other words, market participants tend to provide a consistent reaction to similar market stimuli over time. Technical

Page 13: The practical implication of Technical analysis with Bollinger Bands on empirical study on Dhaka Stock Exchange (DSE)

analysis uses chart patterns to analyze market movements and understand trends. Although many of these charts have been used for more than 100 years, they are still believed to be relevant because they illustrate patterns in price movements that often repeat themselves.

Technical analysis is applicable to stocks, indices, commodities, futures or any tradable instrument where the price is influenced by the forces of supply and demand.

Principles of Technical Analysis:

1. Demand and supply factors 2. Rational and irrational factors 3. Continuous in particular direction 4. Shift of Demand and supply factors 5. Charts representing market action 6. Patterns to forecast forwarded share price

Types of Share Price Movement: 

1. Tertiary Movement – [Day to day movement] 2. Secondary Movement – [A number of weeks or month] 3. Primary Movement – [Period of several months or years]

Types of overall trend under primary movements: There are two types of overall trend under primary movements

1. Bullish Trend 2. Bearish Trend

Bullish Trend: Three phases of a bullish market - revival of confidence, improvement of corporate earnings, speculation & inflation. Bearish Trend: Three phases of a bearish market-abandonment of hopes, low profits and dividends, further distress selling.

Indicators of technical analysis:

Indicators are calculations based on the price and the volume of a security that measure such things as money flow, trends, volatility and momentum. Indicators are used as a secondary measure to the actual price movements and add additional information to the analysis of securities. Indicators are used in two main ways:

1. to confirm price movement and the quality of chart patterns, and 2. To form buy and sell signals.

Types of indicators:

There are many types of indicators as follows:

Trend Indicators: Trend indicators reflect three tendencies in price movements: Up moves, down moves and sideways price moves. These indicators help define prevailing directions/ trends of the price moves by smoothing price data over a certain period of time. In simple words, Trend indicators allow us to visualize Trends in the market.

1. Ichimoku Kinko Hyo 2. Advance Decline Line (ADL) 3. Average Directional Index (ADX) 4. Average Directional Movement Index Rating (ADXR) 5. Commodity Selection Index (CSI) 6. Directional Movement Index (DMI) 7. Double Exponential Moving Average (DEMA) 8. Heiken Ashi 9. Moving Average Convergence and Divergence (MACD) 10. Moving Averages: EMA, SMA and WMA 11. Parabolic SAR 12. Percentage Price Oscillator (PPO) 13. Point & Figure 14. Triple Exponential Moving Average (TEMA) 15. Triple Exponential Moving Average (TRIX)

Momentum Indicators: Momentum indicators show the strength of trends by recording the speed of prices moving over certain time period. At the same time, Momentum indicators track strength and weakness of a trend as it progresses over a given period of time: the highest momentum is always registered at the beginning of a trend, the lowest - at its end point.

1. Accumulative Swing Index (ASI) 2. Advance Decline Ratio (ADR) 3. Aroon Indicator 4. Aroon Oscillator 5. Chande Momentum Oscillator 6. Commodity Channel Index (CCI) 7. Intraday Momentum Index 8. Centre of Gravity 9. Linear Regression Slope 10. Mass Index 11. Momentum Indicator 12. Price Oscillator 13. Qstick 14. Random Walk Index 15. Rate of Change (ROC) 16. Relative Momentum Index (RMI)

Page 15: The practical implication of Technical analysis with Bollinger Bands on empirical study on Dhaka Stock Exchange (DSE)

7 | P a g e   

17. Relative Strength Index (RSI) 18. Smoothed Indexed Rate of Change (SIROC) 19. Stochastics 20. Stochastic RSI 21. Stochastic Momentum Index 22. Ultimate Oscillator 23. Williams %R 24. Williams' Accumulation-Distribution

Volatility Indicators: Volatility indicators show the size and the magnitude of price fluctuations. In any market there are periods of high volatility (high intensity) and low volatility (low intensity). These periods come in waves: low volatility is replaced by increasing volatility, while after a period of high volatility there comes a period of low volatility and so on. Volatility indicators measure the intensity of price fluctuations, providing an insight into the market activity level.

1. Average True Range (ATR) 2. Bollinger Bands (BB) 3. Chaikin Volatility (CHV) 4. Donchian Channel 5. Keltner Bands 6. McGinley Dynamic indicator (MDI) 7. Moving Average Envelopes 8. Starc Bands

Volume Indicators: Volume indicators are used to determine investors' interest in the market. High volume, especially near important market levels, suggests a possible start of a new trend, while low volume suggests trader’s uncertainty and/or no interest in a particular market.

1. Acceleration Bands 2. Market Facilitation Index 3. Chaikin Money Flow (CMF) 4. Chaikin Oscillator 5. Accumulation Distribution Oscillator (ADO) 6. Volume Oscillator (PVO) 7. Demand Index 8. On Balance Volume (OBV) 9. Money Flow

Cycle Indicators: A cycle in the market is determined by a series of repeating patterns. These patterns are, as a rule, dedicated to certain market events, such as seasons, simple day counts, event-to-event sequence, market theories and formulas and so on.

1. Detrended Price Oscillator (DPO) 2. Elliott waves 3. Schaff Trend Cycle 4. Fibonacci 5. Fourier Transform

Conclusions about Technical analysis:

Technical analysts consider the market to be 80% psychological and 20% logical. Fundamental analysts consider the market to be 20% psychological and 80% logical. Psychological or logical may be open for debate, but there is no questioning the current price of a security. Technical analysis focuses directly on the bottom line: What is the price? Where has it been? Where is it going?

In this study I use Bollinger Bands as indicator to analyze some our randomly selected securities of DSE, so I am presenting a brief about this indicator in the next chapter.

Chapter 3 Bollinger Bands

Introduction:

Bollinger Bands is a technical analysis tool invented by John Bollinger in the 1980s, and a term trademarked by him in 2011. Having evolved from the concept of trading bands, Bollinger Bands and the related indicators %b and bandwidth can be used to measure the "highness" or "lowness" of the price relative to previous trades. Bollinger Bands are a volatility indicator similar to the Keltner channel. Bollinger Bands is a versatile tool combining moving averages and standard deviations and is one of the most popular technical analysis tools available for traders.

Bollinger Bands consist of:

Bollinger Bands consist of a middle band with two outer bands. The middle band is a simple moving average that is usually set at 20 periods. A simple moving average is used because the standard deviation formula also uses a simple moving average. The look-back period for the standard deviation is the same as for the simple moving average. The outer bands are usually set 2 standard deviations above and below the middle band. These are listed below-

1. an N-period moving average (MA) 2. an upper band at K times an N-period standard deviation above the moving average

(MA + Kσ) 3. a lower band at K times an N-period standard deviation below the moving average

(MA − Kσ)

Typical values for N and K are 20 and 2, respectively. The default choice for the average is a simple moving average, but other types of averages can be employed as needed. Exponential moving averages are a common second choice. Usually the same period is used for both the middle band and the calculation of standard deviation.

Sharp Charts Calculation: 1. Middle Band = 20-day simple moving average (SMA) 2. Upper Band = 20-day SMA + (20-day standard deviation of price x 2) 3. Lower Band = 20-day SMA - (20-day standard deviation of price x 2)

Chart # i | Closing Price Daily, 20-period/2-deviations Bollinger Bands; Example

Bollinger Bands, however, are created by calculating two standard deviations above and below a 20-day simple moving average. Therefore, the price should remain within the bands about 95% of the time.

The determinative parameter for BB:

In general, the determinative parameter for BB is the period/type of MA, because bands are derivative lines from the MA parameter. The major value for trading of this indicator is in bands. Normal distribution suggests that some variable – in our case this is price, will stay in a range of two standard deviations with a probability ~95%, in range of three standard deviations with a probability more than 99%.

1. MA – period, its type and type of price – close, high, low, etc. 2. Number of standard deviations. The greater this parameter – the wider band lines, and the

less probable that market will touch it. In most cases there is not much sense to apply more than 3 standard deviations.

We should keep in mind, that applying 2 deviations tells that price action will be inside the bands with probability 95%, 3 standard deviations – 99%. So, market will touch the bands very rarely.

If applying of 3 deviations suggests, that price will have to remain between the bands with 99% probability, and market occasionally touches upper or lower band.

The MA period has the same sense as in a simple MA. The longer the MA-period, the more smooth and lazy these MA & BB lines. Also they will be wider. In fact, this is the same sensitivity to most recent price action – if you appoint a short period, then bands of BB will be

very sensitive to price behavior and looks like kinked curves. If you appoint greater period – the line will be smoother and bands range will be wider.

Because there is direct correlation between the deviation and the period, Just to keep it simple – the greater the period, the greater the volatility and deviation. So as deviation is greater – the distance between bands is also wider.

1. Estimation of market volatility:

In general, when the market is calm and quiet – volatility decreases, hence deviation of price from its average also becomes less, and… At the same reasoning the distance between bands becomes greater, when the market turns in sloppy price action or in an impulse and thrusting move.

Chart # ii | Closing Price Daily, 20-period/2-deviations Bollinger Bands; Example

Here you can see – when the market was calm – the distance between the lines was tighter. In March, market fluctuations became wider, hence, volatility was increased and the distance between BB bands then expanded. During the collapse in April, the market was really loud – the bands’ distance has become really wide.

Partially it because of just 2 deviations application Look, how it will be, if we apply 3 deviations:

Chart # iii | Closing Price Daily, 20-period/3-deviations Bollinger Bands; Example

I even have had to eliminate some points, where price previously touched the bands.

2. Classic bounce from Bollinger Bands lines:

As we’ve noted already, due to math laws, price tends to return to the middle of the bands. According to normal distribution, when price reaches any of the bands – it becomes stretched, like a spring and tends to move right back. So, the bands of BB indicator acts like support and resistance:

The whole idea behind the Bollinger bounce is that price tends to return to the middle of the bands.

The longer the time frame you are in, the stronger these bands tend to be. Many traders have developed systems that thrive on these bounces and this strategy is best used when the market is ranging and there is no clear trend.

3. Bollinger Bands squeeze:

This method works better when you give market more room for breathing by appointing just 2 deviations. Why? Because the market has 5 times greater probability to move outside the bands –5 % against ~ 1% when 3 deviations appointed.

Chart # v | Closing Price Daily, 20-period/2-deviations Bollinger Bands; Example

Here we can see that bands squeeze tightly and move almost parallel, range between them is stable. This is an early caution about potential breakout.

Because, calm and very harmonic movement of bands and a tight range between them tell us, that volatility extremely stable. This couldn’t hold too long. Tight range between bands tells, in turn, that volatility is low. This combination tells, that market in extremely calm period - it couldn’t hold too long. Extreme calming is unnatural for markets and this could lead only to a single scenario – growth of volatility and breakout.

So, when market shows a close below some band – this is the most probable direction of the breakout. Especially if it shows a number of closes in this direction. On our chart this is a close below the lower band – hence, we should expect breakout to the downside:

Chart # vi | Closing Price Daily, 20-period/2-deviations Bollinger Bands; Example

In general this approach could be used to identify the starting of new strong move as soon as possible. But, as you understand, you will not see such action very often.

Bandwidth & %b:

In spring of 2010, John Bollinger introduced three new indicators based on Bollinger Bands. They are BB-Impulse, which measures price change as a function of the bands, percent bandwidth (%b), which normalizes the width of the bands over time, and bandwidth delta, which quantifies the changing width of the bands.

%b (pronounced "percent b") is derived from the formula: %b = (Price - Lower Band)/ (Upper Band - Lower Band)

%B quantifies a security's price relative to the upper and lower Bollinger Band. There are six basic relationship levels:

1. %b equals 1 when price is at the upper band 2. %b equals 0 when price is at the lower band 3. %b is above 1 when price is above the upper band 4. %b is below 0 when price is below the lower band 5. %b is above .50 when price is above the middle band (20-day SMA) 6. %b is below .50 when price is below the middle band (20-day SMA)

Bandwidth tells how wide the Bollinger Bands are on a normalized basis. Writing the same symbols as before, and middle BB for the moving average, or middle Bollinger Band: Bandwidth = (upper BB – lower BB) / middle BB.

Some additional advice:

1. If the market penetrates BB band and couldn’t reach the MA line – middle of the range between the bands, then it tells about power of the market in this direction and that the previous move has a solid odds to continue. Just look at chart # vi – market penetrates lower band, but was not able to return even to MA line. Then, the move down continues…;

2. BB bands, especially by applying 2.5-3 deviations and about 20-period could be used as an indicator of overbought/oversold levels and conditions on the market. When the market touches the upper band – the market is overbought, when it touches the lower one – oversold. It is preferable to apply this method not lower than on the daily time frame. A combination of Oversold+ Fib support or Overbought + Fib Resistance has a greater probability to stop the market for some time.

3. BB bands could save you from unwelcome areas to enter the market. It’s safer to buy in the lower half of the range, and Sell in the higher half of the range. Also avoid entering the market, when it stands at the bands – long at higher band, and short at lower band. Because, as we’ve said already – there is a high probability of bouncing in the middle of the range.

4. AS with any other indicator, BB demands fine tuning, by analyzing its application with different pairs and time frames. You should find parameters that most suitable for your trading style and pairs that you trade.

You may apply different variations of the tools that I’ve pointed out. For instance – I said “if the market shows close outside of some band”. You instead could apply not one but 2 or 3 closes. The akin variations are allowed in other strategies with BB. Be free to experiment with the parameters you use, confirmation signals and other things! Your task is to find out how to make more pips on the market. And there is nothing forbidden with any indicator.  

Conclusions about Bollinger Bands: Even though Bollinger Bands can help generate buy and sell signals, they are not designed to determine the future direction of a security. Bollinger Bands serve two primary functions:

1. To identify periods of high and low volatility 2. To identify periods when prices are at extreme, and possibly unsustainable, levels.

Remember that buy and sell signals are not given when prices reach the upper or lower bands. Such levels merely indicate that prices are high or low on a relative basis. A security can become overbought or oversold for an extended period of time. Finally, the bands are just bands, not signals. A band of the upper Bollinger Band is NOT a sell signal. A band of the lower Bollinger Band is NOT a buy signal.

Implementations & Analysis

Introduction:

For implementation & analysis I have taken closing prices of ten listed company then I have done some calculation with excel to find the moving average, deviation, upper band & lower band. Using these data I have found three charts for each company such as-

4. Closing Price Daily, 20-period/2-deviations Bollinger Bands 5. Daily Deviation of closing prices 6. Daily %b of Bollinger Bands

Then I have presented some analysis on these charts.

The selected companies are shown below:

1. LankaBangla Finance Ltd. 2. Meghna Petroleum Ltd. 3. United Airways (BD) Ltd. 4. Jamuna Oil Company Ltd. 5. Padma Oil Company Ltd. 6. Active Fine Chemicals Ltd 7. Bangladesh Submarine Cable Company Ltd. 8. Islami Bank Bangladesh Ltd. 9. Square Pharmaceutical Ltd. 10. Titas Gas Transmission & Dist. Co. Ltd.

I have also presented a regression analysis for each company. The regressions are done by two variables which are closing price of each company as dependent variable & Index of DSE as independent variable. These regression analyses are done to find dependence of company’s closing price on Index of DSE.

Finally I have presented the Bollinger Bands charts of Index of DSE to highlight the market condition of DSE.

After the 23rd March the market was gradually becoming calm. During the collapse in April, the market was really calm – the bands’ distance between the lines was really tighter. Here we can see that bands squeeze tightly and move almost parallel, range between them is stable. This is an early caution about potential breakout. Because, calm and very harmonic movement of bands and a tight range between them tell us, that volatility extremely stable. This couldn’t hold too long. Extreme calming is unnatural for markets and this could lead only to a breakout. On 20th April, it has occurred and it may continue.

Chart #6 | Daily %b of Bollinger Bands; Meghna Petroleum Ltd

Since, from chart#6 we see that the value of %b is always in between 0.20 to 0.82. So the price always remains between bands. Again the last value of %b is 0.40 which indicate that the price is near the meddle line.

Regression analysis:

I have taken 34 days price of Meghna Petroleum Ltd and Index of DSE to find the relationship between them. Then I have run regression by SPSS taking price as dependent variable and Index as independent variable. The result summery of regression is shown below by Table#4 | Model summery, ANOVA, Coefficients.

From the table we see that 32.6% of the variation of price of Meghna Petroleum Ltd can be explained by the Index of DSE and the sensitivity of the price of Meghna Petroleum Ltd to Index of DSE is 0.011, that is, if the Index of DSE will be increased by Tk. 1/- then price of Meghna Petroleum Ltd will be increased by Tk. 0.011/-.

Chart #7 | Closing Price Daily, 20-period/2-deviations Bollinger Bands; United Airways (BD) Ltd

Chart #8 | Daily Deviation of closing prices; United Airways (BD) Ltd

Here we can see from chart#7 & chart#8- during the March, volatility was increased and the distance between BB bands then expanded. But during the April the volatility gradually became stable and, hence, the bands’ distance between the lines was really tighter. Here we can see that bands squeeze tightly and move almost parallel, range between them is stable. This is an early caution about potential breakout.

Again, from chart# 7, in April we have noticed that there occurred a classic bounce from Bollinger Bands lines and price tends to return to the middle of the bands. So, the bands of BB indicator acts like support and resistance & it indicates that there is less probability of breakout.

Chart #9 | Daily %b of Bollinger Bands; United Airways (BD) Ltd

Since, we know that %b is below 0 when price is below the lower band. So from chart#9 we see that there is two breakout of the lower band which occurred prior to the 12th March & after the 29th March. Again the last value of %b is 0.20 which indicate that the price is near the lower band.

Chart #10 | Closing Price Daily, 20-period/2-deviations Bollinger Bands; Jamun Oil Company Ltd

Chart #11 | Daily Deviation of closing prices; Jamun Oil Company Ltd

Here we can see from chart#10 & chart#11- the deviation was gradually decreasing and, hence, the bands’ distance between the lines was gradually decreasing. After 18th April, we can see that bands squeeze tightly and move almost parallel, range between them is stable, but prior to the 18th April bands distance was expanded. This combination tells that market is in extremely calm period - it couldn’t hold too long. Extreme calming is unnatural for markets and this could lead only to a single scenario – growth of volatility and breakout.

Here we can see from chart#13 & chart#14- the deviation was gradually decreasing and, hence, the bands’ distance between the lines was gradually decreasing. Before the 26th April, bands squeezed tightly and moved almost parallel, range between them was stable. This was an early caution about potential breakout and exactly it was occurred on 26th April.

Since, 26th April, the value of %b was below 0.00, so the price breakout the lower band. Again the last value of %b is -0.90 which indicate that the price is below the lower band.

Regression analysis:

I have taken 34 days price of Padma oil company Ltd and Index of DSE to find the relationship between them. Then I have run regression by SPSS taking price as dependent variable and Index as independent variable. The result summery of regression is shown below by Table#8 | Model summery, ANOVA, Coefficients

Chart #20 | Daily Deviation of closing prices; Bangladesh Submarine Cable Company Ltd

We know, calm and very harmonic movement of bands and a tight range between them tell us, that volatility extremely stable. This couldn’t hold too long. Tight range between bands tells, in turn, that volatility is low. This combination tells, that market in extremely calm period - it couldn’t hold too long. Extreme calming is unnatural for markets and this could lead only to a single scenario – growth of volatility and breakout.

Here we can see that bands squeeze tightly and move almost parallel, range between them is stable. This is an early caution about potential breakout.

Since the probability of breakout is high & the last value of %b is above 0.50 & near 1.00, that means the last price is between the middle & upper line, so I think breakout will be occurred with upper band.

Regression analysis:

I have taken 34 days price of Bangladesh Submarine Cable Company Ltd. and Index of DSE to find the relationship between them. Then I have run regression by SPSS taking price as dependent variable and Index as independent variable.

Chart #23 | Daily Deviation of closing prices; Islami Bank Bangladesh Ltd

We see from chart#22 – there was occurred a huge breakout of the lower band on 12th April. Before the 12th April, bands squeezed tightly and moved almost parallel, range between them was stable. This was an early caution about potential breakout and exactly it was occurred on 12th April.

Here we can see from the chart#23- the deviation was rapidly increased after the 21st April and, hence, the bands’ distance between the lines was rapidly expanded.

Chart #24 | Daily %b of Bollinger Bands; Islami Bank Bangladesh Ltd

Since, on 13th April, the value of %b was less than 0.00, so the price breakout the lower band, again, it return back between the bands on 26th April. The last value of %b is 0.20 which indicate that the price is near the lower band.

Regression analysis

I have taken 34 days price of Islami Bank Bangladesh Ltd. and Index of DSE to find the relationship between them. Then I have run regression by SPSS taking price as dependent variable and Index as independent variable. The result summery of regression is shown below by Table#16 | Model summery, ANOVA, Coefficients; Islami Bank Bangladesh Ltd

Here we can see from chart#25 & chart#26- the deviation was gradually decreasing and, hence, the bands’ distance between the lines was gradually decreasing. This combination tells that market is in extremely calm period - it couldn’t hold too long. Extreme calming is unnatural for markets and this could lead only to a single scenario – growth of volatility and breakout.

Since the price touches the upper band, so the breakout may occur with the upper band.

Chart #31 | Index of DSE, Daily, 20-period/2-deviations Bollinger Bands; Dhaka Stock Exchange (DSE)

Chart #32 | Daily Deviation of Index of DSE; Dhaka Stock Exchange (DSE)

We know, calm and very harmonic movement of bands and a tight range between them tell us, that volatility extremely stable. This couldn’t hold too long. Tight range between bands tells, in turn, that volatility is low. This combination tells, that market in extremely calm period - it couldn’t hold too long. Extreme calming is unnatural for markets and this could lead only to a single scenario – growth of volatility and breakout.

Here we can see that bands squeeze tightly and move almost parallel, range between them is stable. This is an early caution about potential breakout.

Chart #33 | Daily %b of Bollinger Bands; Dhaka Stock Exchange (DSE)

Since the probability of breakout is high & the last value of %b is 0.09, that means- the last Index of DSE is exactly near the lower band, so I think breakout will be occurred with lower band.
