A trend line refers to a graphical representation of price movement on a chart, where a straight line is drawn by connecting a series of either high or low points. This line helps to identify the direction and strength of the trend, allowing traders and investors to make informed decisions about buying or selling securities.
By analyzing the slope of the trend line, one can determine whether the trend is bullish (upward) or bearish (downward), and can predict potential future price movements. In technical analysis, trend lines are a valuable tool for identifying and analyzing market trends, and are commonly used in conjunction with other indicators and chart patterns to gain a better understanding of market dynamics.
