#看懂K线

The candlestick chart, also known as K-line chart, is the most common tool in technical analysis, constructed using four data points: 'opening price, highest price, lowest price, closing price.' Each candlestick represents price changes over a specific period: a red candlestick (or green candlestick) typically indicates that the closing price is higher than the opening price, suggesting a bullish trend; a black candlestick (or red candlestick) indicates a bearish dominance.

The length of the shadows reflects market volatility and buying/selling pressure: a long upper shadow represents significant selling pressure; a long lower shadow indicates strong buying interest. Continuous long red candlesticks may suggest a strong upward trend; conversely, continuous black candlesticks often signal a downward trend.

Learning to read candlesticks helps in assessing support and resistance, trend reversals, and timing for entering and exiting trades, making it one of the foundational skills for cryptocurrency or stock trading.
