The K-line chart (candlestick chart) is the most basic tool for all cryptocurrency traders. By default, Binance's spot and futures trading interfaces display K-line charts, where each candle represents the open, close, high, and low prices for a specific time period. This article explains how to read K-line charts in the most straightforward way. It is most effective to open the Binance Official Website and look at any spot market while reading this article, or download the Binance Official APP to practice on the go. Apple users, please check the iOS Installation Guide.
4 Prices Contained in One Candle
A K-line candle consists of a body and upper/lower shadows (wicks), corresponding to four key prices:
- Open Price: The trading price at the beginning of this time period.
- Close Price: The trading price at the end of this time period.
- High Price: The highest trading price during this time period.
- Low Price: The lowest trading price during this time period.
If the close price is higher than the open price, this K-line is displayed in green (bullish candle), indicating that the price has risen during this period.
If the close price is lower than the open price, this K-line is displayed in red (bearish candle), indicating that the price has fallen during this period.
Note: The red and green colors in US and A-share markets are opposite (In China, red means up and green means down; in the West, green means up and red means down). Binance defaults to green for up and red for down, which can be changed in the settings.
How to Read the Body and Shadows
- Body: The rectangular block between the open and close prices.
- Upper Shadow: The thin line above the body; the highest point is the highest price of this period.
- Lower Shadow: The thin line below the body; the lowest point is the lowest price of this period.
The longer the body, the stronger the buying/selling power; the longer the shadow, the stronger the pushback from opposing forces in that direction, serving as traces of a "fight."
- Long bullish candle with no shadows → Bulls are completely in control.
- Long bearish candle with no shadows → Bears are completely in control.
- Long upper shadow with small body → Price pumped and fell back; resistance above.
- Long lower shadow with small body → Price dipped and bounced back; support below.
How to Switch Timeframes
The length of time each K-line represents is the "timeframe". The top bar of Binance has options like 1m / 5m / 15m / 1h / 4h / 1D / 1W:
| Timeframe | One Candle Represents | Suitable Trading Style |
|---|---|---|
| 1m | 1 minute | Ultra-short term scalping |
| 5m | 5 minutes | Day trading |
| 15m | 15 minutes | Intraday swing |
| 1h | 1 hour | Most common for day trading |
| 4h | 4 hours | Most common for swing trading |
| 1D | 1 day | Medium to long term |
| 1W | 1 week | Long term dollar-cost averaging |
Beginners are advised to start with 1h and 4h. Timeframes that are too short have a lot of noise and make it easy to be swayed by emotions.
A Simple Chart Reading Process
After opening the K-line chart of a trading pair, judge in this order:
- Look at the daily chart (1D) first → Understand whether the macro trend is up, down, or ranging.
- Then look at 4h → Find medium-term structures and support/resistance levels.
- Finally look at 1h → Find specific entry timing.
- Observe the volume histogram → Price action is only valid when supported by volume.
Four Basic Patterns You Must Know
1. Marubozu (Large Bullish / Bearish Candle)
A candle with a long body and short shadows, accompanied by increased trading volume. Appearing at a key level means trend initiation or acceleration.
2. Doji
The open and close prices are almost identical, forming a cross. A Doji at a high level is a top reversal signal, and at a low level is a bottom reversal signal.
3. Hammer
Very long lower shadow, small body, and almost no upper shadow. Looks like a "hammer." Appearing at the end of a downtrend is a bottom bounce signal.
4. Hanging Man (Inverted Hammer / Shooting Star)
Very long upper shadow, small body, and almost no lower shadow. Appearing at the end of an uptrend is a top pullback signal.
Volume Histogram
The histogram below the K-line chart shows the trading volume corresponding to each K-line:
- Volume bar colors match K-line colors: Green bars represent buying volume (upward), red bars represent selling volume (downward).
- Price up, volume up → Strong upward momentum.
- Price up, volume down → Uptrend might be exhausting.
- Price down, volume up → Strong selling pressure.
- Price down, volume down → Selling pressure weakening, possible bottoming out.
Three Commonly Used Moving Averages
By default, Binance K-line charts overlay three Moving Averages (MA):
- MA7: 7-period average price, short-term trend.
- MA25: 25-period average price, medium-term trend.
- MA99: 99-period average price, long-term trend.
When MA7 crosses above MA25 → Short-term bullish. When MA7 crosses below MA25 → Short-term bearish. MA7, 25, 99 stacked upwards in order (Bullish alignment) → Upward trend.
Practical Features of Binance K-Line Charts
Drawing Tools
The left toolbar has tools like trend lines, horizontal lines, rectangles, Fibonacci retracements, etc. Beginners only need to master horizontal lines and trend lines to mark key support and resistance levels.
Switching K-Line Styles
You can switch styles in the top right corner: "Candlestick / Line / Hollow Candles / Heikin Ashi". Beginners should just use standard Candlesticks; study other styles after getting familiar.

Click the "Full Screen" button in the top right corner of the chart to zoom in. On mobile, long-press the K-line area to enter detailed view mode.
Frequently Asked Questions
Q: Can K-line charts really predict prices?
A: K-lines cannot predict; they only reflect the buying and selling battles that have already happened. Its value lies in helping you identify market sentiment and find entry points with higher probabilities, not giving you the answer of "will it go up or down in the next second." No technical analysis tool can predict prices 100%.
Q: Is trading on the 1-minute K-line a faster way to make money?
A: Quite the opposite. The 1-minute chart has extreme noise, and most fluctuations are random. Fees and slippage will eat up all your profits. The shorter the trading timeframe for beginners, the faster they lose money. Start with 1h and 4h.
Q: What is the number unit on the K-line chart?
A: By default, it is priced in USDT (because you are in the BTC/USDT market). If you switch to a BTC trading pair (like ETH/BTC), the unit becomes BTC. The trading pair name in the top left corner will display this clearly.
Q: What if the K-line chart on my phone is too small to see?
A: In the APP, long-press the K-line chart to switch to landscape mode, doubling your field of view. Also, you can use the two-finger pinch gesture to zoom in and out on the K-line density. Directly maximizing the browser window on the web version offers the clearest view.
