As an investor, learning to interpret candlestick charts is a fundamental skill. Candlestick charts display the changes in opening, closing, highest, and lowest prices for each time period, reflecting market sentiment. A red candlestick usually represents a closing price increase, while a green candlestick represents a closing price decrease. By observing candlestick patterns, such as 'hammer', 'engulfing', or 'doji', one can assess the changes in market bullish and bearish forces. Once, I anticipated a rebound early through the 'double bottom' candlestick pattern, successfully stopping loss and reversing. Mastering candlestick analysis can help us make more calm and rational buying and selling decisions.
