What do you think of a bitcoin K-line if you want to get started quickly? K-line chart is a tool that visualizes price fluctuations and is widely used in financial trading scenarios such as stocks, gold, crude oil and cryptocurrencies.

Understanding the K-line structure is the basic skill of technical investors. Compared with a simple price link chart, it can provide richer market information.

This article will take you to understand the principles of K-line charts from scratch, the practical application of Bitcoin K-line charts, common form recognition techniques, and teach you how to choose the appropriate time period based on your own trading habits.

What is the essence of the K-line chart?

K-line chart (also known as candle chart) is a graphical way to record changes in asset prices. Each K-line contains four key data: opening price, closing price, highest price and lowest price. It is one of the most basic and important tools in technical analysis and is widely used in the stock market, foreign exchange, commodity and digital currency markets.

Each K-line usually appears as a red or green column, so it is also called a "K-bar". The following figure is an example of Bitcoin’s K-line on Binance platform, where red and green alternate lines represent price fluctuations over different time periods - each in this figure represents 4 hours.

By observing the K-line arrangement and pattern changes, we can judge that the current market is in an upward, downward or fluctuating stage.

The core component of the K-line

Each K-line consists of five elements:

• Opening price
• Close price
• The highest price in the current cycle
• The lowest price in the current cycle
• Rising and falling status (the closing price is higher than the opening price, and the other way around will fall)

The specific drawing logic is as follows:

• The physical part connects the opening and closing prices
• The upper and lower extension lines represent the highest point and lowest point in this period, respectively, called the upper shadow line and the lower shadow line.
• Default color settings: Green means rising, red means falling (color can be customized)

Because its appearance is similar to a candle, it is also called a candle chart:

• Candle body (physical) : reflects the price range from opening to closing
• Candle wick (hadow) : The upper shadow shows the highest price, the lower shadow shows the lowest price
• Color difference : Green = close>opening (up), red = close

For example:

• Green entity and no shadow, indicating that the bulls are strong and the price is rising steadily
• The red entity is obvious and has a long shadow line, which indicates that the short side is dominant but there is competition during the session, and eventually closes at the low level.

Time cycle and the uniqueness of the Bitcoin market:

Different time units will generate different K-line charts, for example:

• A "1-hour K-line" records price fluctuations within 60 minutes
• A "Daily K" reflects the price trend of 24 hours a day

Unlike traditional stock markets that have a fixed opening and closing time, the cryptocurrency market operates around the clock. The system uses the price at the start of each cycle as the opening price and the price at the end of the cycle as the closing price. The time benchmark is usually set locally by UTC or exchange.

For example, the daily K-line automatically extracts four prices of the day every day to form a K-line; if a 4-hour K-line is used, 6 will be generated in a day; while the 15-minute K-line has 96 K-lines a day.

Longer periods such as weekly K and monthly K are also common. Medium- and long-term traders pay more attention to larger time frames such as 4-hour, daily, and weekly lines.

Advantages of K-line charts over ordinary price curves

The normal price chart only shows continuous changes in the closing price:

And the K-line chart can provide more dimensions of information:

Ordinary trend charts cannot reflect the volatility amplitude and the power comparison between buyers and sellers, and the K-line chart can not only see the direction, but also infer the long-short game status and judge market sentiment.

• Colors intuitively show rise and fall
• The length of the body length and short shadow line can help judge the fluctuation intensity and potential reversal signals

How to interpret a single K-line? Analysis of typical forms and practical signals

Beginners do not have to analyze all K-lines one by one. It is recommended to be familiar with several typical forms first and grasp the possible trend turning points.

Large entity and short shadow K-line meaning (strong entry or kinetic energy failure)

This type of K-line has almost no upper and lower shadows, and the solid part is very long, looking like a pure red or pure green column. It is one of the easiest to identify and most valuable signals.

• The obvious green positive line: It indicates that the buyer has strong strength
• The obvious red big negative line: It means that selling pressure has an absolute advantage

However, it is necessary to judge its significance based on the location:

• A big positive/negative line breakout appears after consolidation : it may be a signal of the trend establishment (strong start)
• A large K-line appears again after a sharp rise or fall : it may mean that momentum is about to run out (end of the trend)

As shown in the figure below, the two big green Ks on the left and right appear in different positions, with completely different meanings.

The meaning of long shadow line and small entity K-line (trend turning point or market hesitation)

This type of K-line entity is very short, but the upper and lower shadows are particularly long, and are often called "cross", "nail lines" or "pin".

This shows that the bulls and bears compete fiercely during this period, but in the end no one can win, and it often occurs before the trend turning point or during the oscillation period.

• If it occurs after a continuous rise or fall : it may be an early warning of a trend reversal
• If it appears in the sideways consolidation stage : it may be just that the market is waiting and watching, and no direction choice has been made yet

As shown in the figure below, a pattern similar to a "needle" can be seen near multiple highs and lows, reflecting the intensification of market hesitation.

Two forms appear one after another (the probability of changing the disk increases significantly)

If a large entity K-line appears first in the same area, followed by a long shadow K-line, it means that the long-short forces are changing rapidly. At this time, the market may change suddenly, so be vigilant.
