The Chart Types

3.1 – Overview

In technical analysis, price is usually summarized using four important values: Open (O), High (H), Low (L), and Close (C). Together, these four values are called OHLC data. They provide a compact picture of what happened to an asset during a particular period.

The challenge is how to display all four values clearly on a chart.

For example, if we study one trading day, we have four price points. For 10 trading days, we have 40 individual OHLC values. For several months or a full year, the amount of information becomes much larger. A good charting method is therefore essential because it should present this information without making the chart difficult to understand.

Many conventional chart types, such as pie charts, area charts, and ordinary column charts, are not particularly useful for detailed technical analysis. A line chart can be useful for observing the broad direction of price, but it generally focuses on only one price value, usually the closing price.

Three important ways of displaying price data are:

1. Line chart
2. Bar chart
3. Japanese candlestick chart

This chapter focuses mainly on Japanese candlestick charts. Before studying candlestick patterns, however, it is useful to understand how line charts and bar charts work and why candlesticks are so widely used by traders.

3.2 – The Line Chart

The line chart is one of the simplest ways to display price information. It normally plots one price value for each period and connects those points with a line.

In financial markets, the closing price is most commonly used.

Suppose we want to study the closing prices of a stock over five trading days:

A line chart would plot these five closing prices and connect them from left to right.

The same concept can be applied to different time frames. A chart can be created using:

• Daily closing prices
• Weekly closing prices
• Monthly closing prices
• Hourly closing prices
• 15-minute closing prices
• 5-minute closing prices
• Other user-defined intervals

Advantages of a line chart

The biggest advantage of a line chart is simplicity.

With a quick glance, a trader can understand the broad direction of an asset. It is relatively easy to identify:

• An upward trend
• A downward trend
• A sideways market
• Major changes in price direction
• Long-term price movements

Line charts can therefore be particularly useful when the primary objective is to study the general trend.

Limitations of a line chart

The simplicity of a line chart is also its biggest weakness.

A conventional closing-price line chart does not show the complete OHLC information for each period. It normally does not tell us:

• Where the period opened
• The highest price reached
• The lowest price reached
• The relationship between the opening and closing prices

Consider two trading days that both close at ₹100.

On the first day, the stock may have opened at ₹99, reached ₹101, fallen to ₹98, and closed at ₹100.

On another day, it may have opened at ₹110, reached ₹112, fallen to ₹99, and finally closed at ₹100.

A line chart showing only the closing price would show ₹100 for both days. Much of the trading activity that occurred within the period would therefore remain invisible.

For this reason, while line charts are excellent for simplicity and broad trend analysis, they provide limited information for detailed price-action analysis.

3.3 – The Bar Chart

A bar chart provides considerably more information than a simple line chart because a single price bar can represent all four OHLC values.

A traditional price bar consists of:

1. Vertical line – Shows the high and low of the period.
2. Left-hand tick – Shows the opening price.
3. Right-hand tick – Shows the closing price.

Suppose the OHLC data for a stock is:

• Open = ₹65
• High = ₹70
• Low = ₹60
• Close = ₹68

The vertical portion extends from ₹60 to ₹70. A small mark on the left identifies the opening price of ₹65, while a mark on the right identifies the closing price of ₹68.

Therefore, one bar communicates four pieces of information at once.

How to read a bar

The relationship between the opening and closing ticks is important.

If:

Close > Open

the period finished above its opening price. This is generally considered a bullish or positive period.

For example:

• Open = ₹46
• High = ₹51
• Low = ₹45
• Close = ₹49

The market opened at ₹46 and finished at ₹49. Buyers were able to push the price higher during the period.

If:

Close < Open

the period finished below its opening price. This is generally considered a bearish or negative period.

For example:

• Open = ₹74
• High = ₹76
• Low = ₹70
• Close = ₹71

The market opened at ₹74 but finished at ₹71.

The colours used to display bullish and bearish bars depend on the charting platform. Common choices include green and red, but traders can customize these colours.

Understanding the range

The distance between the high and low is known as the price range:

Range = High − Low

For example:

• High = ₹120
• Low = ₹110

Therefore:

Range = ₹120 − ₹110 = ₹10

A large range means the asset moved through a wider price interval during that period. A small range means the movement between the high and low was narrower.

However, range should not automatically be interpreted as trading volume or trading activity. A large range indicates substantial price movement, but volume is a separate measure.

Advantages of bar charts

Bar charts have several strengths:

• They display OHLC information.
• They show the trading range.
• They show the relationship between open and close.
• They can be used across different time frames.
• They are useful for traditional price-action analysis.

Limitations of bar charts

The main difficulty for many beginners is visual interpretation.

A chart containing hundreds of bars can become difficult to scan quickly. The opening and closing ticks are relatively small, and recognizing recurring price patterns may require more effort.

This does not mean bar charts are ineffective. Many professional and experienced traders continue to use them. The choice ultimately depends on personal preference and the type of analysis being performed.

For someone learning technical analysis from the beginning, Japanese candlesticks are often easier to interpret because the relationship between open and close is represented by a clearly visible body.

3.4 – Japanese Candlesticks

Japanese candlestick charts provide another way to display OHLC information.

Like a bar, a single candlestick represents four important prices:

• Open
• High
• Low
• Close

The major difference is how the information is visually presented.

Instead of using small opening and closing ticks, a candlestick uses a rectangular real body to show the relationship between the open and close. Thin lines extending above and below the body show the high and low.

This makes the price action visually prominent and allows traders to understand the market’s movement quickly.

Candlestick charts are now among the most widely used chart types in technical analysis.

3.5 – A Brief History of Japanese Candlesticks

The history of candlestick charting is associated with Japan and the historical trading of rice.

One of the most frequently mentioned figures in this history is Munehisa Homma, an 18th-century Japanese rice trader. Historical accounts describe Homma as an influential trader who studied market prices, supply and demand, and trader psychology.

The precise origins and development of modern candlestick charting are more complicated than the popular story sometimes suggests. Various forms of Japanese price-recording and market analysis developed over time, and it is difficult to attribute the entire modern candlestick system to a single individual.

Candlestick analysis remained relatively unfamiliar to Western traders for many years.

In the late 20th century, Steve Nison played a major role in introducing and popularizing Japanese candlestick techniques among Western traders. His book Japanese Candlestick Charting Techniques, published in the early 1990s, became an influential reference for traders interested in candlestick analysis.

Many candlestick patterns continue to use traditional Japanese names, such as:

• Doji
• Hammer
• Hanging Man
• Harami
• Engulfing
• Morning Star
• Evening Star

The names may sound unusual at first, but they become easier to remember after studying the structure and market context behind each pattern.

3.6 – Candlestick Anatomy

Understanding the anatomy of a candlestick is essential before learning candlestick patterns.

A standard candlestick contains three primary visual elements:

1. Real body
2. Upper shadow
3. Lower shadow

The body represents the distance between the opening and closing prices.

The shadows, sometimes called wicks, show the prices reached beyond the body during the period.

Bullish candlestick

A bullish candlestick forms when:

Close > Open

In other words, the asset finishes the period at a higher price than where it started.

Suppose:

• Open = ₹62
• High = ₹70
• Low = ₹58
• Close = ₹67

The real body extends from ₹62 to ₹67.

The upper shadow extends from ₹67 to ₹70.

The lower shadow extends from ₹58 to ₹62.

The structure can therefore be understood as:

High → Upper Shadow → Close → Real Body → Open → Lower Shadow → Low

Many charting platforms display bullish candles in green, blue, white, or another selected colour.

Bearish candlestick

A bearish candlestick forms when:

Close < Open

Suppose:

• Open = ₹456
• High = ₹470
• Low = ₹420
• Close = ₹435

The real body extends from ₹435 to ₹456.

The upper shadow extends from ₹456 to ₹470.

The lower shadow extends from ₹420 to ₹435.

The structure can therefore be understood as:

High → Upper Shadow → Open → Real Body → Close → Lower Shadow → Low

Bearish candles are commonly displayed in red or black.

The colours are not a fundamental part of candlestick analysis. What matters is the relationship between the open and close and the position of the high and low.

3.7 – Real Body, Upper Shadow and Lower Shadow

The three main components of a candle provide different information.

Real body

The real body represents the distance between the opening and closing prices.

A large bullish body indicates that the closing price was substantially above the opening price.

A large bearish body indicates that the closing price was substantially below the opening price.

A small body indicates that the opening and closing prices were relatively close.

Importantly, body size alone does not prove that buying or selling activity was high. It primarily tells us about the price movement between the open and close. Volume and other market information are needed to assess trading activity more directly.

Upper shadow

The upper shadow connects the top of the real body to the high of the period.

It shows how far the price moved above the open or close before finishing at its final level.

A long upper shadow can indicate that prices moved significantly higher during the period but were unable to maintain those higher levels by the close.

Lower shadow

The lower shadow connects the bottom of the real body to the low of the period.

It shows how far the price moved below the open or close.

A long lower shadow can indicate that prices moved significantly lower but later recovered from those lows.

The meaning of a shadow becomes more useful when it is considered together with the candle’s location, trend, support and resistance, volume, and surrounding candles.

3.8 – An Example of Three Candles

Consider the following OHLC data:

Day 1

The stock opened at ₹430 and closed at ₹438.

Because:

₹438 > ₹430

the candle is bullish.

The high was ₹444 and the low was ₹425.

Day 2

The stock opened at ₹445 and closed at ₹450.

Because:

₹450 > ₹445

the candle is bullish.

The price reached ₹455 on the upside and ₹438 on the downside.

Day 3

The stock opened at ₹445 but closed at ₹437.

Because:

₹437 < ₹445

the candle is bearish.

The high was ₹455 and the low was ₹430.

Plotting these three candles makes the OHLC information much easier to visualize than reading the numbers alone.

This is one of the major strengths of candlestick charts: they convert numerical price data into an easily recognizable visual structure.

3.9 – What a Candlestick Tells You

A candlestick can answer several important questions about a trading period.

Where did the price open?

The body begins at the opening price.

Where did the price close?

The body ends at the closing price.

What was the highest traded price?

The top of the upper shadow identifies the high.

What was the lowest traded price?

The bottom of the lower shadow identifies the low.

Was the period bullish or bearish?

Compare the closing price with the opening price.

How large was the price movement?

Compare the high and low to understand the total range.

How strong was the movement between open and close?

Look at the size of the real body.

Was there rejection from higher or lower prices?

Long upper or lower shadows may provide clues, especially when considered in the right market context.

This makes candlesticks particularly useful for price-action analysis.

3.10 – Long and Short Candles

Candles can have different body and shadow sizes.

A long-bodied candle means there is a relatively large difference between the opening and closing prices.

For example:

• Open = ₹100
• Close = ₹115

The body is ₹15.

A short-bodied candle means the opening and closing prices are relatively close.

For example:

• Open = ₹100
• Close = ₹102

The body is only ₹2.

A long body can indicate strong directional price movement during the period, while a small body indicates relatively limited net movement between the open and close.

However, context is important. A long candle after a major news event can have a different interpretation from a long candle appearing during an established trend.

Similarly, a small body does not necessarily mean that nothing happened. The price could have moved substantially in both directions during the period and eventually closed near its opening price.

3.11 – Understanding Candlestick Range

The total range of a candle is:

Range = High − Low

For example:

• High = ₹150
• Low = ₹135

Range:

₹150 − ₹135 = ₹15

The real body is different from the total range.

For a bullish candle:

Body = Close − Open

For a bearish candle:

Body = Open − Close

This distinction is important because a candle may have a large total range but a small body.

For example:

• Open = ₹100
• High = ₹120
• Low = ₹80
• Close = ₹102

The total range is ₹40, but the body is only ₹2.

This tells us that the market experienced substantial movement during the period, even though the opening and closing prices were very close.

Such distinctions become particularly important when studying individual candlestick patterns.

3.12 – Time Frames in Technical Analysis

A time frame refers to the duration represented by one candle or one price bar.

The appropriate time frame depends on the trader’s objective, strategy, market, and holding period.

Common time frames include:

• Monthly
• Weekly
• Daily
• 4-hour
• 1-hour
• 30-minute
• 15-minute
• 5-minute
• 1-minute

Modern charting platforms may offer many additional intervals.

Monthly chart

One monthly candle represents the price action of an entire month.

Typically:

• Open = opening price of the first trading session of the month
• High = highest price during the month
• Low = lowest price during the month
• Close = closing price of the final trading session of the month

A monthly chart is useful for studying long-term trends.

Weekly chart

A weekly candle represents the trading activity of one week.

For markets that normally trade Monday through Friday, the candle generally begins with the first trading session of the week and ends with the final trading session.

The exact structure can vary because of market holidays and exchange schedules.

Weekly charts are useful for:

• Medium- to long-term trend analysis
• Major support and resistance
• Broader market structure
• Reducing some of the noise found on lower time frames

Daily chart

One daily candle normally represents one trading session.

It contains:

• The session’s opening price
• Highest price reached during the session
• Lowest price reached during the session
• Closing price

Daily charts are widely used by swing traders and investors.

Intraday charts

Intraday charts divide a trading session into smaller periods.

Examples include:

• 30-minute charts
• 15-minute charts
• 5-minute charts
• 1-minute charts

A 15-minute candle represents the OHLC data for a 15-minute interval.

A 5-minute candle represents the OHLC data for a five-minute interval.

The number of candles appearing during a trading session depends on the exchange’s actual trading hours and the selected interval. Therefore, fixed candle counts should not be treated as universal.

3.13 – Choosing the Right Time Frame

There is no single “best” time frame for every trader.

The appropriate time frame depends largely on the trading style.

These are broad examples rather than strict rules. A trader may combine several time frames.

For example, a swing trader might use:

• Weekly chart to understand the major trend
• Daily chart to identify the setup
• 1-hour chart to refine the entry

This is often called multi-time-frame analysis.

3.14 – Information Versus Noise

One of the most important concepts in chart analysis is the difference between information and noise.

As the time frame becomes smaller, the number of candles increases. This provides more individual price observations, but it can also make the chart more sensitive to short-term fluctuations.

For example, a long-term investor may not gain much from watching every one-minute price movement of a stock. Many of those movements may have little relevance to an investment decision that is expected to play out over several years.

On the other hand, an intraday trader may need short-term price information because their trades are opened and closed within the same trading session.

Therefore:

Lower time frame ≠ automatically better information.

The useful question is:

Does this time frame provide information relevant to my trading objective?

A successful approach is not necessarily to collect the maximum amount of data. It is to identify the data that matters and avoid being distracted by irrelevant fluctuations.

3.15 – Why Multiple Time Frames Can Be Useful

Looking at only one time frame can sometimes provide an incomplete picture.

Imagine that a stock appears to be rising strongly on a 5-minute chart. If the daily chart shows that the stock is approaching a major resistance zone, the short-term signal may need to be interpreted differently.

Similarly, a temporary decline on a 15-minute chart may look bearish in isolation but could simply represent a correction within a larger long-term uptrend.

A multi-time-frame approach can therefore help traders understand:

• The broader trend
• Intermediate price structure
• Short-term entry opportunities
• Important support and resistance areas
• Potential conflicts between short-term and long-term signals

However, using more charts does not automatically improve a trading decision. Too many time frames can create confusion. The chosen time frames should have a clear purpose.

3.16 – Candlesticks Are Not Predictive by Themselves

Candlestick charts are powerful visualization tools, but a candlestick does not guarantee what will happen next.

For example, a bullish candle does not mean that the price must continue rising.

Similarly, a bearish candle does not guarantee that the price will fall further.

Candlestick interpretation becomes more meaningful when combined with factors such as:

• Trend
• Support and resistance
• Volume
• Market structure
• Price gaps
• Volatility
• Momentum
• Broader market conditions
• Fundamental or news-related events

A candlestick pattern should therefore be treated as evidence, not certainty.

This distinction is important because technical analysis deals with probabilities rather than guaranteed outcomes.

3.17 – Common Mistakes Beginners Make

Mistake 1: Looking only at candle colour

A green or bullish candle is not automatically a strong buying signal.

The candle’s size, shadows, location, preceding trend, volume, and surrounding price structure also matter.

Mistake 2: Ignoring the time frame

A pattern on a 5-minute chart may have a very different significance from a similar-looking pattern on a weekly chart.

Mistake 3: Assuming every pattern works

Candlestick patterns can fail. No pattern provides certainty.

Mistake 4: Confusing range with volume

A large high-low range means significant price movement. It does not necessarily mean that trading volume was high.

Mistake 5: Using too many indicators and time frames

Adding more information does not always improve analysis. Excessive information can create conflicting signals and decision fatigue.

Mistake 6: Ignoring the broader trend

A candle should not always be interpreted in isolation. Its location within the larger market structure can be more important than its appearance.

3.18 – Line Chart vs Bar Chart vs Candlestick Chart

No chart type is universally superior.

A line chart is excellent when simplicity is the priority.

A bar chart provides complete OHLC information in a traditional format.

A candlestick chart provides the same core OHLC information in a visually intuitive format and makes the relationship between opening and closing prices particularly easy to recognize.

3.19 – Why Candlesticks Are So Popular

Candlesticks combine information density with visual simplicity.

A single candle can tell us:

• Where the period started
• Where it ended
• How high the price moved
• How low the price moved
• Whether buyers or sellers had the stronger net movement
• Whether prices were rejected from higher or lower levels
• How large the movement was compared with surrounding candles

When many candles are placed together, they create a visual record of market behaviour.

This makes it easier to identify structures such as:

• Trends
• Consolidation
• Breakouts
• Reversals
• Rejections
• Momentum changes
• Potential support and resistance reactions

Candlesticks therefore became a natural foundation for the study of price action and candlestick patterns.

3.20 – Important Formulae to Remember

Several simple calculations are useful when studying candlesticks.

Total Range

Range = High − Low

Bullish Body

Body = Close − Open, when Close > Open

Bearish Body

Body = Open − Close, when Open > Close

Direction

• Close > Open → Bullish candle
• Close < Open → Bearish candle
• Close = Open → Open and close are equal; the candle may resemble a doji depending on the exact structure and charting conventions

These calculations are simple, but understanding them is fundamental to reading candlestick charts.

3.21 – Practical Example

Suppose a stock has the following data:

The candle is bullish because:

₹220 > ₹200

The real body is:

₹220 − ₹200 = ₹20

The total range is:

₹225 − ₹190 = ₹35

The upper shadow is:

₹225 − ₹220 = ₹5

The lower shadow is:

₹200 − ₹190 = ₹10

This one candle therefore tells us that the stock opened at ₹200, moved as low as ₹190, climbed as high as ₹225, and eventually closed at ₹220.

The numbers become much easier to understand when converted into a visual candle.

3.22 – The Bigger Picture

A candlestick is only one part of technical analysis.

It is important to avoid interpreting candles mechanically. The same candle can have different meanings depending on where it appears.

For example, a long lower shadow:

• Near important support may suggest rejection of lower prices.
• During a strong downtrend may simply represent temporary buying.
• In the middle of a sideways market may have limited significance.
• Around a major news event may reflect unusually high volatility.

This is why experienced traders generally study context before pattern names.

Instead of asking only:

“What candlestick pattern is this?”

it is often more useful to ask:

“What happened to price, where did it happen, and what does the surrounding market structure suggest?”

That approach leads to better and more disciplined chart analysis.

Key Takeaways

1. OHLC stands for Open, High, Low, and Close. These four values summarize the price action of a trading period.
2. A line chart normally uses closing prices and is excellent for observing broad trends, but it does not display complete OHLC information.
3. A bar chart displays the open, high, low, and close using a vertical range line and opening and closing ticks.
4. Japanese candlesticks also display all four OHLC values but use a real body and shadows, making price movement visually easier to interpret.
5. A bullish candle forms when Close > Open.
6. A bearish candle forms when Close < Open.
7. The real body represents the distance between the open and close.
8. The upper shadow shows the movement between the high and the top of the body.
9. The lower shadow shows the movement between the low and the bottom of the body.
10. The total range is calculated as High − Low.
11. A large candle body represents a large net movement between the opening and closing prices. It should not automatically be interpreted as proof of high trading volume.
12. Time frames determine how much market activity is represented by each candle.
13. Monthly and weekly charts are generally more useful for studying broader trends, while intraday charts provide greater detail for short-term trading.
14. Lower time frames create more candles and more short-term price information, but they can also contain more market noise.
15. The best time frame depends on the trader’s objective, strategy, risk management, and holding period.
16. Multi-time-frame analysis can help traders compare short-term price action with the broader trend.
17. Candlestick patterns should not be treated as guaranteed predictions. They are tools for interpreting market behaviour and probabilities.
18. The most effective candlestick analysis combines the candle with trend, support and resistance, volume, market structure, volatility, and broader market conditions.
19. Candlesticks are popular because they present a large amount of price information in a compact and visually intuitive form.
20. The goal of technical analysis is not to predict every price movement. It is to identify useful information, manage uncertainty, and avoid being overwhelmed by market noise.

Final Perspective

Understanding charts is one of the foundations of technical analysis. Before studying advanced indicators or complicated candlestick patterns, a trader should first understand what a single candle represents.

Every candle is a small story about a particular period. It tells us where the market opened, how far buyers and sellers pushed the price, where the market traded at its highest and lowest levels, and where it finally closed.

The real power comes when individual candles are viewed together. A series of candles can reveal trends, momentum, consolidation, rejection, and changes in market behaviour.

Japanese candlesticks make this process easier because the OHLC information is converted into a simple visual language. Once the anatomy of a candle becomes familiar, reading a chart becomes much less intimidating.

At the same time, a good trader should remember that a chart is a representation of market activity, not a crystal ball. Candles can provide valuable clues, but no candle or pattern can remove uncertainty from financial markets.

The next step is therefore not simply to memorize dozens of candlestick names. It is to understand how candles interact with one another, how they behave around important price levels, and how the larger trend changes their meaning. That foundation makes the study of candlestick patterns far more practical and useful.
