In the world of day trading, stock charts are arguably the most informative data summarization tools available. Almost every single day trader uses some form of charts to aid his/her decision making process. There are a variety of different chart types available, but candlestick charts are easily one of the most popular amongst day traders. Whereas simple line charts may be sufficient for investors, candlestick charts provide extra data that can be valuable to day traders.

Brief History of Candlestick Charts

The usage of candlestick charts goes back hundreds of years. It’s believed that Japanese rice traders used these charts to create a summarization and visualization of supply and demand. A trader by the name of Steve Nison is credited for introducing these charts to the Western World. Nison popularized these charts and still remains a credible authority on the theory and application of candlestick charting.

Fast forward to present time and candlestick charts have become a ubiquitous trading tool utilized by many professionals. These charts are available in most trading software packages and have a variety of practical applications.


What are Candlesticks?

Each candlestick holds four key pieces of data: the open, the close, the high, and the low. These charts can be applied to any timeframe. The main advantage to candlestick charts is that they provide more information than a simple line chart.


Components of Candlesticks

A candlestick consists of its real body as well as an upper and lower shadow (also referred to as a wick).


The body represents the open and close prices for the given timeframe, while the wicks represent the highs and the lows for the timeframe.

If a stock closes above its opening price, it is represented by a hollow real body (or a green body). If a stock closes below its opening price, it is represented by a filled real body (or a red body). The visual representation of these candlesticks may vary slightly by charting platform, however the data is the same.


How to Use this Information

As a day trader, you should be interested in the actual trading activity that goes on for a given timeframe. Candlestick charts shed light on the trading that went on before a closing price was agreed upon.

For example, a basic line chart may show that a stock closed at $10. This data may be sufficient enough for an investor, however day traders tend to seek more data about the activity that led to the closing price. For the example above, a candlestick chart may show that the stock opened at $11, hit a low of $8 and then closed at $10. This would be a completely different scenario than if the stock opened at $6, hit a high of $11 and closed at $10. The main point being that a candlestick chart tells the story behind the closing price of a stock.


This information can be used to determine the sentiment surrounding a stock. Are traders bullish or bearish? Did the stock close near its highs or lows? How volatile is the stock? The goal of using candlesticks is to better understand the trading activity of the market.

Candlestick formations can be indicative of market sentiment and volatility.

Bullish Candles

If a stock closes near its highs, it would be considered to be bullish for the given timeframe. Candlesticks will also indicate the level of bullishness.


Bearish Candles

If a stock closes near its lows, it would be considered bearish for the given timeframe. Of course, this analysis (for both bullish and bearish candles) is relevant to the given timeframe and not necessarily indicative of longer-term trends.



The height of a candlestick can indicate how volatile a stock is. For example, a stock trading in a range of $7-$11 for the day may be considered volatile, whereas a stock trading between $10-$10.50 may not.


Candlestick Patterns

For the sake of this introductory post, we won’t delve too deep into candlestick patterns, however we may expand on the topic at a later point in time.

There are hundreds of different candlestick patterns. Just like chart patterns, these candlestick patterns can be used to predict future market action. Patterns may consist of one candlestick or multiple, and certain candlesticks are more significant than others.

Keep in mind that you don’t need to utilize these patterns to take advantage of candlestick charting. The charts are a beneficial tool on their own. That being said, some traders look for patterns to predict future market price action.

Here are some commonly used candlestick patterns:

Bullish Engulfing – A bullish engulfing pattern is characterized by a green (or hollow) candle that fully engulfs the real body of a previous red (or black) candle. This can be indicative of a move higher.


Bearish Engulfing – A bearish engulfing pattern is characterized by a red (or black) candle that fully engulfs the real body of a previous green (or hollow) candle. This can be indicative of a move lower.


Doji – A doji is characterized by an equal (or close to equal) opening and closing price. This candle represents a neutral sentiment in which supply and demand are closely leveled. The significance of this candle is relative to previous trading activity.


Wrapping Things Up

Understanding the basics of candlestick charting is fairly simple. Each candlestick tells a story about the trading activity during a certain timeframe. This data can be incredibly helpful for traders looking to gauge the sentiment of the market.

While candlesticks are relatively simple in nature, there are plenty of advanced analyses that may be applied. We may discuss some of the more advanced tactics in future articles. Stay tuned!
