When you open the Binance trading page, the most prominent feature is the chart composed of red and green bars. This is the K-line chart, also known as a candlestick chart — the most fundamental analysis tool for all traders. If these bars make absolutely no sense to you, don't worry. After reading this article, you'll be able to understand them.

The Basic Structure of a Candlestick
Each candlestick represents price movement over a specific time period. This period could be 1 minute, 5 minutes, 1 hour, 1 day, and so on, depending on the timeframe you select.
A single candlestick contains four key price points:
- Open: The price at the beginning of the time period
- Close: The price at the end of the time period
- High: The highest price reached during the time period
- Low: The lowest price reached during the time period
Each candle consists of two parts:
The body (the thick bar): Connects the open and close prices. The longer the body, the greater the price movement during that period.
The wicks/shadows (the thin lines): The upper wick extends from the top of the body to the high, and the lower wick extends from the bottom of the body to the low. Wicks indicate that the price reached those levels but couldn't hold them.
What Do Red and Green Represent
In Binance's default settings:
Green (or hollow candle) = Price went up
- The close is higher than the open
- This means the price rose overall during this period
- The bottom of the body is the open, the top is the close
Red (or filled candle) = Price went down
- The close is lower than the open
- This means the price fell overall during this period
- The top of the body is the open, the bottom is the close
An easy way to remember: Green means up, red means down. See green — price went up. See red — price went down.
Note that color conventions can differ across countries and platforms. In the Chinese stock market, red represents a price increase and green represents a decrease — the exact opposite of Binance's default settings. If you're accustomed to the A-share color scheme, you can switch the K-line color scheme in the Binance app settings.
How to Read Information from Candlestick Patterns
Body Length
- Long green body: Price rose significantly, strong buying pressure
- Long red body: Price fell significantly, strong selling pressure
- Short body (any color): Little price movement, buyers and sellers are evenly matched
Wick Length
- Long upper wick: Price spiked up but was pushed back down — indicates selling pressure above
- Long lower wick: Price dipped sharply but was pulled back up — indicates support below
- Almost no wicks: Strong trend with little back-and-forth
Common Single-Candle Patterns
Bullish engulfing candle (Marubozu): A long green body with almost no wicks. Price rose steadily from open to close — buyers were completely in control. Appearing after a period of decline, it may signal a trend reversal.
Bearish engulfing candle: A long red body with almost no wicks. Price fell steadily from open to close — sellers were completely in control. Appearing during an uptrend, it warrants caution about a potential pullback.
Doji: A very short body with roughly equal upper and lower wicks. The open and close are nearly the same — an intense tug-of-war between buyers and sellers with neither side winning. When a doji appears at the end of a trend, it's often a signal of a potential reversal.
Hammer: A very short body with a long lower wick (at least twice the body length) and almost no upper wick. Appearing at the end of a downtrend, it may hint at a bottom reversal — the price dropped sharply but was pulled back up with force.
Inverted hammer / Shooting star: A very short body with a long upper wick and almost no lower wick. Appearing at the end of an uptrend, it may hint at a top reversal — the price surged but was met with heavy selling.
Volume Bars Below the K-Line Chart
You may have noticed a row of bars of varying heights below the K-line chart. These are volume bars, representing the trading volume during the corresponding time period.
Volume bars are also color-coded:
- Green volume bars correspond to bullish candles
- Red volume bars correspond to bearish candles
The size of the volume is very important:
- Price up + volume increasing: The rally is backed by strong buying, and the trend may continue
- Price up + volume decreasing: The rally lacks momentum and may be nearing a top
- Price down + volume increasing: Panic selling, and the decline may accelerate
- Price down + volume decreasing: Selling pressure is weakening, and the price may be near a bottom

Switching Timeframes
Above the K-line chart, you'll see a row of timeframe options: 1m, 5m, 15m, 1h, 4h, 1D, 1W, etc.
- Scalpers typically watch 1-minute to 15-minute candles
- Day traders typically watch 1-hour to 4-hour candles
- Medium to long-term investors typically watch daily and weekly candles
Start with the daily chart (1D) to understand the broader trend, then switch to shorter timeframes for details.

Viewing Detailed Data for a Single Candle
Long-press or tap on any candle, and the screen will display that candle's specific data: open, close, high, low, volume, etc. This is a great way for beginners to learn — every time you see an interesting candle, tap it to see its values and deepen your understanding.
Tips for Beginners Reading K-Line Charts
1. Don't over-rely on a single candle. The signal from a single candle is often unreliable. Look at the candles before and after it, and observe the overall trend and rhythm. Patterns formed by three to five candles are much more meaningful than a single one.
2. Learn to identify trends before studying patterns. The most basic judgment is: if the chart moves from lower-left to upper-right, it's an uptrend; from upper-left to lower-right, it's a downtrend. Studying specific candlestick patterns becomes more effective once you have this foundation.
3. Look at multiple timeframes simultaneously. The daily chart might show an uptrend, but the weekly chart could show a downtrend. Different timeframes can present different trends. The general approach is to use longer timeframes to determine direction and shorter timeframes to find entry points.
4. Don't ignore volume. Price movements without supporting volume have much lower credibility. A sharp rise with low volume could be a false breakout.
5. K-line analysis isn't a crystal ball. Candlestick charts reflect past price movements — they can't accurately predict the future. They're an analytical tool, not a fortune-telling device. Never make major trading decisions based solely on candlestick patterns. Always consider other factors for a comprehensive assessment.
6. Learn through practice. Theory alone won't stick. Pick a cryptocurrency you're interested in, spend a few minutes each day looking at its K-line chart, and try to analyze what the red and green bars are telling you. After a month or two, you'll notice a significant improvement in your chart-reading ability.
Conclusion
K-line charts may look complex, but the core logic is actually quite simple: green means the price went up during that period, red means it went down, longer bars mean bigger changes, and longer wicks mean more back-and-forth. Once you've mastered these basics, you'll already be able to extract useful market information from K-line charts. As for more advanced candlestick patterns and analysis methods, you can gradually build that knowledge through practice.
