#看懂K线 Cryptocurrency K-Line Beginner's Guide — Master Core Techniques in Three Minutes

By June 2025, cryptocurrency investors need to grasp the basics of K-lines to cope with market volatility. Key Points:

Colors and Shapes: Bullish Line (Green/Red) closes higher than the opening price, indicating an upward trend; Bearish Line does the opposite. The length of the shadow reflects the strength of resistance/support; a long upper shadow warns of selling pressure, while a long lower shadow suggests a bottom rebound.

Classic Combinations: Patterns such as Hammer (Bottom Reversal), Doji (Bull-Bear Game), and Dark Cloud Cover (Top Risk) should be verified with trading volume to avoid false breakouts.

Multi-Period Linkage: Short-term trading focuses on the 1-hour chart, while long-term investment emphasizes daily/weekly charts, supplemented by MACD and RSI indicators to improve accuracy.

Experts remind that K-lines are merely probabilistic tools and should be paired with risk control and fundamental analysis; beginners are advised to practice through simulated trading.
