To understand candlestick patterns, you can start from several aspects. First, look at the colors: a bullish candle (red or hollow) indicates strong buying and a rising market, while a bearish candle (green or filled) indicates strong selling and a declining market. Next, observe the size of the body; a large body signifies a clear trend in either direction. Then, examine the length of the wicks; a long upper wick indicates strong selling pressure, while a long lower wick indicates strong buying pressure. Among common candlestick patterns, a doji signifies a balance between buyers and sellers, and an opening gap reflects changes in market sentiment. However, it is essential to combine these observations with tools like trading volume and moving averages for a comprehensive analysis of stock price trends.
