K-line is the foundation for observing market sentiment. First, learn to read candlestick charts, then use BOLL to find breakouts and pullbacks. Next, use MACD to assess trend strength; trading in the direction of the trend is more secure. RSI helps determine overbought and oversold conditions, allowing for early detection of potential turning points. Finally, VOL helps you see changes in trading volume, identify signals of major players entering and exiting the market, and grasp the market fluctuations brought by increased volume.
