K-Line charts show a trading pair’s price movements over different time intervals. Each K-Line displays the opening, closing, highest, and lowest prices for a given interval. You can use K-Lines alongside technical indicators to analyze market trends.

This guide explains how to read and customize K-Line charts using the Futures page in the LBank App.

How to View a K-Line Chart

  1. Open the LBank App, log in to your account, and go to「Futures.

  2. Select the trading pair you want to view to open its trading page.

  3. Tap the chart icon in the upper-right corner, as shown below, to view the K-Line chart and related market data.

  4. Above the chart, you can view the last price, mark price, 24-hour high, 24-hour low, trading volume, and trading turnover.

📌Note: The 24-hour market data and an individual K-Line cover different time periods. Make sure to distinguish between them.

How to Read a K-Line

  1. Each K-Line represents a specific time interval and contains four prices:

 

Price

Description

Open

The price at the start of the interval.

Close

The price at the end of the interval.

High

The highest traded price during the interval.

Low

The lowest traded price during the interval.

  1. A K-Line consists of a body and wicks:

Component

Price Range

Body

The range between the opening and closing prices.

Upper wick

Extends from the top of the body to the highest price during the interval.

Lower wick

Extends from the bottom of the body to the lowest price during the interval.

  1. Typically, a green K-Line indicates that the closing price is higher than the opening price, while a red K-Line indicates that the closing price is lower. The actual colors depend on your chart settings.

  2. The current K-Line continues to update until its interval ends. Its body, wicks, and color may change as the traded price moves. For example, 

    • Suppose a 1-hour K-Line has the following prices

Price

Value

Open

80,000 USDT

Close

81,000 USDT

High

81,500 USDT

Low

79,500 USDT

  • The K-Line’s body and wicks cover the following ranges:

Component

Price Range

Body

80,000–81,000 USDT

Upper wick

81,000–81,500 USDT

Lower wick

79,500–80,000 USDT

Note: These figures are for illustration only and do not represent actual market prices

    • The countdown corresponds to the currently selected K-Line interval.

    • To turn it off, clear「Countdown」.

What Should You Keep in Mind When Using K-Line Charts?

  1. Distinguish between closed and unclosed K-Lines: The current K-Line continues to change until its interval ends. Do not treat its shape as final before it closes.

  2. Confirm the trading pair and interval: Price trends may differ across trading pairs and intervals. Check both before analyzing the chart.

  3. Avoid relying on a single signal: K-Lines and technical indicators do not guarantee future price movements. Do not make trading decisions based solely on one K-Line or indicator.

  4. Understand the risks of futures trading: Futures trading involves leverage and liquidation risk. K-Line analysis is not a substitute for managing margin, positions, and trading risk.
