What are candlesticks?
Candlesticks are used in quantitative trading for representing the Open, High, Low, and Close price movements of the tradable instrument (security, derivative, currency etc.). Candlesticks resemble the shape of a real life candlestick and hence, the name.
The candlesticks are distinguished by the following colours:
- White Candlesticks or Green Candlesticks: Indicate an uptrend
- Black Candlesticks or Red Candlesticks: Indicate a downtrend
Candlesticks have various sizes, shapes and even colours. The reason for this is that the candlesticks are based on prices. Since the prices keep varying, the size and shape of the candlesticks also vary due to the nature of their anatomy. And that makes them different.
These various shapes and sizes are indicative of market psychology but, at times, can be highly effective in helping you predict the future market direction.
History of candlesticks
Candlesticks were developed in the 17th century in Japan. This is the reason why they are also known as Japanese candlesticks.
After their invention, locals in Japan began using candlesticks while trading rice. This idea was gradually adopted by various people and across countries and kept evolving for the better. The evolution of the same led to what the candlesticks are at present.
Japanese Candlesticks are thought to have been introduced to the West in the book, ‘Japanese Candlestick Charting Techniques by Steve Nison. The West developed the bar point and figure analysis almost 100 years later.
In ancient Japan, the principles were applicable to Rice and today they are applicable to stocks.
Munehisa Homma, a renowned rice merchant from the Japanese town of Sakata, traded in the Dojima market in the 1700s. Further study of candlesticks mentions ‘Sakata’s Methods’ or ‘Sakata’s Rules’, that are based on the name of this particular market.
Homma is said to have developed candlestick charts during his lifetime by studying years of historical data and comparing them with weather conditions. This study also helped him understand the role of emotions on the value and pricing behind the trade of rice.
Anatomy of candlesticks
The anatomy of the Candlesticks has stayed almost similar throughout the ages to give us the current shape and meaning. It consists of 4 distinct values namely:
- The opening price,
- Closing price,
- The highest prices for a given interval, and
- The lowest prices for a given interval.
It’s like a combination of a line chart and a bar chart, where each bar represents all four important pieces of information for an interval.
The hollow or the filled portion of the candlestick is called as the body of the candlestick.
- Long Body - Indicates heavy trading in one direction and strong buying or selling pressure
- Small Body - Indicates lighter trading or little buying or selling activity
The long thin lines above and below the body is called the shadow of the candlestick.
- Upper Shadow - High is marked by the topmost part of the upper shadow
- Lower Shadow - Low is marked by the bottom part of the lower shadow
Candlesticks show and define the price movements as open, close, high and low over a vertical line. It consists of the following:
- Upper tip - High
- Lower tip - Low
- Candle body - The range between Open and Close
- Top End
- Bottom End
And occasionally, you may also observe:
- Upper shadow
- Lower shadow
Further, the body is represented by a Hollow Body Candlestick or a Filled Body Candlestick.
Hollow Body Candlestick
- When the stock closes at a price higher than the opening price
- The body is white
- The bottom of the body depicts the open price
- The top of the body shows the closing value of the stock
Filled Body Candlestick
- When the stock closes at a price lower than the opening price
- The body is black

Categories of candlestick patterns
Trade analysts use candlestick patterns to recognize market turning points and they are utilised to reduce one’s exposure to market risks. Also, candlestick patterns can be based on two candlesticks and at times even a series of multiple candlesticks can be used.
- Candlestick patterns are divided into the number of Candlesticks: One, Two, Three and more.
- Candlestick patterns are categorised into two broad categories, namely Bullish and Bearish.
When the body is filled, black or red, it means that the close is lower than the open and is known as the bearish candle.
It implies that the bearish price movements led to the prices going down and hence, the closing price turned out to be lower than the opening price.
Different types of bearish candles
If the body is empty, is white or green then it means that the close was higher than the open making it a bullish candle.
It implies that the bullish price movements led to the prices going up and hence, the closing price turned out to be higher than the opening price.
Different types of bullish candles
This body depicts the price range between the open and close of the day’s trading.
Difference between Bullish candles and Bearish candles

|2||Second-most Bullish||Second-most Bearish|
|3||Moderate Bullish||Moderate Bearish|
|4||Neutral Bullish||Neutral Bearish|
|5||Least Bullish||Least Bearish|
Representation of Candlesticks
The thin vertical lines above and below the body are called the wicks or shadows which represent the high and low prices of the trading session.
The representation of the candlesticks is as follows:
- Strength is represented by a bullish or green candle
- Weakness is represented by a bearish or red candle
- Buying usually is followed by a green candle
- Selling is followed by a red candle
- You must look for a prior trend. If you are looking at a bullish reversal pattern, then the prior trend should be bearish.

Following are some candlesticks and their interpretation that will be helpful for trading:
How to detect the candlestick patterns in actual charts?
A daily candlestick chart shows the security’s open, high, low, and close price for the day. The candlestick’s body (which we discussed above) shows the link between opening and closing prices.

You can detect these simple candlestick patterns which are:
- Bullish swing
- Bearish swing
- Bullish pin bar
- Bearish pin bar
- Inside bar
- Outside bar
Bullish swing is a simple one which is a 3-candle pattern. The second candle has the lowest low among the three. It signals a possible bullish movement in the prices.
A bearish swing is the opposite of a bullish swing. It is also a 3-candle pattern and the second candle here, has the highest high.
Bullish pin bar
Pin bars are quite frequent and are the most powerful patterns. It is commonly known that a pin bar has a very long shadow and a small body.
Also, a pin bar is not only such a candle, but it must come from the surrounding price action. Hence, a bullish pin bar must have a lower low with respect to the previous candle.
A “small” body can be defined as a body whose width is less than the candle range divided by 3. A bullish pin bar will then have the body located in the upper half of the candle.
Bearish pin bar
The bearish pin bar is similar to the bullish pin bar, but the body is now located in the lower half of the candle and it has a higher high than the previous candle.
Inside bar is a pattern that is made of two candles. The second entire candle is included in the range of the first candle.
The inside bar pattern shows a contraction in volatility that may be a prelude to a strong directional explosion.
The outside bar is the opposite of the inside bar. The candle range includes the entire previous candle.

Drawbacks of reading candlestick patterns for trading
The drawbacks of reading candlestick patterns for trading can be listed as follows:
A candlestick can look different in every time-frame
A candlestick pattern might seem perfectly formed in one timeframe but it can also appear completely opposite in another. This makes it difficult to trust the message of a candlestick pattern 100 percent. Therefore it can cause doubt for traders to decide and execute their trades. If the candlestick is of sufficient size, it might appear on multiple timeframes, but this is an uncommon occurrence.
Unreliability of candlestick patterns over the higher frequencies
During the high frequencies such as a minute data will have a lot of candlestick patterns but a lot of price fluctuations will make it highly difficult to trade. This can lead to an impact on your risk management practice while trading.
In technical analysis, candlestick patterns are often considered a lagging indicator because you need to wait until the close of a candle before entering a trade. This has many drawbacks, with the most important being that lagging indicators only record the results, so it leaves room for the trader to decide or speculate on the next price movements.
