#看懂K线 Understanding candlestick (K-line) charts is key to trading success. Each candle shows price movement within a set time frame—open, high, low, and close. A green (or white) candle means price went up; red (or black) means it fell. Patterns like doji, hammer, and engulfing reveal market sentiment. Combining these with volume and trend analysis can help predict future price moves. Mastering K-line charts takes practice, but it's a valuable skill for any trader.
